Behavior is the product of interconnected brain regions that work together as networks. This case study examines whether there are differences between a participant with a large congenital left temporal lobe cyst, which impacted the volume of structures in the region, and control subjects of similar age on cognitive tasks and network connectivity as measured by resting-state functional magnetic resonance imaging (rs-fMRI).

The case participant (CP; 71 year old female) and controls (CON; n = 25; 48% female) were recruited as part of a larger aging study. CON were chosen from the larger study population by age (+/- 10 years from CP; Range = 68-86 years). Cognitive tasks included: Shopping list memory task, Montreal Cognitive Assessment, WAIS-IV subtests: Digit Span, Digit-Symbol, Symbol Span, and Letter-Number Sequencing. For rs-fMRI, we administered four blood-oxygen level dependent (BOLD) functional connectivity (rs-fMRI) scans at 6 minutes each. Image processing was conducted using the CONN toolbox. Independent sample t-tests evaluated differences between CP and CON. Segregation was evaluated in the Auditory (Au), Cerebellar-basal ganglia (CBBG), Cingulo-Opercular Task Control (COTC), Dorsal Attention (DA), Default Mode (DMN), Fronto-Parietal Task Control (FPTC), Salience (Sa), Sensory Somatomotor Hand (SSH), Sensory Somatomotor Mouth (SSM), Visual (Vi), and Ventral Attention (VA) networks to assess CP’s functional segregation by network throughout the brain. Bonferroni correction was applied to account for multiple comparisons in cognitive testing (.05/7 for significance at p < 0.007) and network segregation (.05/11 for significance at p < .005).

Independent samples t-tests did not reveal significant differences across cognitive tasks (t(24) <1.04, p > .05). Network segregation did not reveal significant differences between CP and CON across networks examined (t(24) < 1.269, p > .005). However, DMN and DA segregation trended toward significance (t(24) = -2.724, p = .006 and t(24) =-2.006, p = .028), respectively) with CP demonstrating lower segregation as compared to CON.

CP performed similarly on cognitive testing to CON, indicating that the congenital presence of a large temporal lobe cyst did not impact global cognition, list learning and memory, working memory, or processing speed. CP did not demonstrate significantly different segregation across networks of interest after Bonferroni correction. Our cognitive performance results are consistent with a similar case-study examining language, which revealed intact linguistic abilities (Tuckete et al., 2022). The lack of differences in cognitive performance and segregation highlight the capacity for plasticity in the human brain, even in the presence of a large structural abnormality. This also suggests that the processes of aging in this case are not markedly different from controls. In future research we intend to expand on this case study by evaluating right temporal to hippocampal seeds and language network seeds to delve deeper into memory and language functioning.

Gulf War Illness (GWI) is a debilitating multi-symptom condition that affects nearly a third of 1990-91 Gulf War (GW) veterans. Symptoms include chronic pain, debilitating fatigue, gastrointestinal issues, and cognitive decrements. Prior studies have documented reduced cognitive functioning in this affected population, particularly in the areas of memory, attention and response inhibition. To date, research has focused on cognitive functioning in male and female veterans together. Very limited research has reported on GW women's cognitive functioning separately mostly due to scarcity of data on women veterans. In this study, we had the unique opportunity to utilize a newly combined neuropsychological test dataset from women GW veterans in the Boston, Biorepository and Integrative Network (BBRAIN) for GWI. The aim was to compare neuropsychological outcomes with toxicant exposures in women veterans with and without GWI.

Cognitive data from the BBRAIN biorepository was used for this study. The sample consisted of 62 women veterans who were deployed to the Persian Gulf War from 1990-91. Neuropsychological test scores included the Conners Continuous Performance Test Third Edition (CPT3), Delis-Kaplan Executive Function System (D-KEFS) Color-Word Interference, and the California Verbal Learning Test Second Edition (CVLT-II). War-related exposure to chemical weapons, anti-nerve gas pills and pesticides were measured by a self-reported survey. For analysis, war-related exposure was classified into three groups: controls with 0-6 days of exposure; cases with 0-6 days of exposure and cases with 7 or more days of exposure. Multiple linear regression modeling was used to measure differences in neuropsychological scores across the three groups by each war-related exposure.

After adjusting for age, education and other exposures, an increase in duration of exposure to pesticides was significantly associated with worse CPT3 commission errors, fewer words correct in the CVLT-II trials 1-5, and an increase in self-corrected errors on DKEFS Color-Word Interference Test Trials 1, 2 and 4 (p<0.05). More days reported hearing chemical alarms and seeing smoke from oil well fires was significantly associated with fewer words correct on all CVLT-II trials, and more self-corrected errors on Color-Word Interference Trials 2 and 4 (p<0.05). An increase in exposure duration to pyridostigmine bromide anti-nerve gas pills was associated with fewer words correct on the CVLT-II learning Trials 1-5 and short delay recall and an increase in self-corrected errors on Color-Word Interference Trials 2, 3, and 4 (p<0.05). When associations were adjusted for PTSD, all significant associations stayed constant (p<0.05).

In this study, women veterans with GWI who had higher levels of exposure to pesticides, oil well fires and who took more antinerve gas pills during the war are showing increased learning difficulties and more deficits in attention and response inhibition. Future research should examine if similar patterns of neuropsychological symptoms are also present in male GW veterans with higher war-time related toxicant exposures.

More than 30 years after the 199091 Gulf War (GW), approximately 200,000 veterans are still suffering from Gulf War Illness (GWI). Veterans who have this multi-symptom disorder experience impaired cognition, chronic pain, sustained fatigue, and gastrointestinal issues. GWI is believed to be associated with neurotoxicant exposures during the war. Prior research has shown cognitive deficits in combined samples of male and female GW veterans with GWI. These studies have shown that veterans with GWI have cognitive decrements in memory, learning and sustained attention. Studies have yet to compare neuropsychological outcomes by sex. This is mainly due to the lack of collected data on women GW veterans in the past. This study aims to analyze neuropsychological differences in males compared with female veterans with GWI and in those with neurotoxicant exposures from the Boston, Biorepository and Integrative Network (BBRAIN) for GWI repository dataset.

The total sample included 297 veterans with GWI (women n=50, men n=247) who were deployed to the 1990-91 Gulf War with an average age of 52 years. GWI case status was defined by the Kansas GWI criteria. Neuropsychological data including the Conners Continuous Performance Test Third Edition (CPT3), Delis-Kaplan Executive Function System (D-KEFS) Color-Word Interference Test, and the California Verbal Learning Test (CVLT-II) were combined from the BBRAIN repository datasets. War-related exposures, including chemical weapons, anti-nerve gas pills and pesticides were measured by a self-reported survey. Multiple linear regression was used to analyze the association between sex, war-related exposures, and neuropsychological test score outcomes.

After adjusting for age, education level and PTSD, men had a significantly lower number of words correct in the CVLT-II learning Trials 1-5, short delay recall and long delay recall compared with women veterans (p<0.05). The two groups also differed significantly in CPT3 commission scores, and total time on the D-KEFs Color-Word Inference total times in Trials 1 and 2 with men performing worse (p<0.05). Reported exposure to chemical weapons, pesticides, pyridostigmine bromide (PB) anti-nerve gas pills or smoke from oil well fires were all significantly associated with fewer words correctly recalled on all learning trials of the CVLT-II, long delay, and short delay to a greater degree in men as compared to women (p<0.05). Reported exposure to chemical weapons or smoke from oil well fires were significantly associated with more commission errors on CPT3 in men with GWI (p<0.05). Chemical alarms, smoke from oil well fires and PB were associated with slower response time on the Color-Word Interference test Trial 1 in men compared with women veterans.

In this study, men with GWI demonstrated significantly poorer performance in verbal memory, learning, response speed and attention. Male veterans reporting neurotoxicant exposures during the war also showed worse learning and verbal memory, impulsivity and response speed decrements compared to exposed women veterans. Future research should consider men and women separately when examining outcomes from war-related exposures.

Parental history (PH) of problematic substance use has been identified as a risk factor for adolescent substance use, which can lead to increased use in adulthood. Researchers hypothesize that individuals with PH exhibit premorbid differences in their reward processing, increasing their likelihood of engaging in reward-driven behavior. Studies have shown that preadolescents with PH have greater activation in their putamen and nucleus accumbens (NA); however, most research has only investigated PH of alcohol use (PHA), not PH of drug use (PHD). Additionally, limited research has assessed whether reward processing develops differently among youth with (PH+) to youth without (PH-). The present study utilizes the national, prospective Adolescent Brain Cognitive Development SM (ABCD) Study to examine whether reward anticipation in the nucleus accumbens (NA) differs in preadolescents with and without parental substance use history and whether patterns of reward anticipation change over time during a two-year follow-up period. Further, it will also examine whether PHA and PHD predict similar activation patterns.

The current sample (N=6,600, Mage = 10.9; range = 9-13.8 years old; 46.7% female) was drawn from the national ABCD Study. To assess reward processing, the Monetary Incentive Delay Task (MID), a fMRI task-based paradigm, was administered at baseline and 2 year follow-up. The primary regions of interest (ROI) were the left and right NA and neutral vs anticipation of large rewards was the selected contrast. The Family History Assessment was used to assess problematic parental alcohol and drug use for both parents, with scores ranging from 0-2, with two indicating that both parents demonstrate problematic use. Three PH contrasts (PH- vs.PH+1, PH-vs.PH+2, & PH+1 vs. PH+2) were created for each group (PHA and PHD) (Martz et al., 2022). Separate linear mixed-effect models with predictors variables (parental contrasts, timepoint, and parental contrasts-by-time-point) and covariates (age, sex, race/ethnicity, income, parental education, parental warmth, parental monitoring, and the random effects of MRI model, family status, and subject) were run to predict reward anticipation.

Results indicated that PHA and,not PHD, was predictive of reward anticipation. PHA+1 youth showed greater activation in the l-NA (b= .02827, p= .03) and r-NA (b= .03476, p=.005), compared to PH- youth. Additionally, PHA+1 youth showed greater activation in the r-NA (b=-.07029, p=.008) compared to PHA+2 youth, but not in the l-NA. Those with PHA+2 demonstrated blunted activity in both the l-NA (b= -.07244, p=.02) and right nucleus accumbens (b= -.1091, p=001) when compared to those with PH-. No interactions with time were found.

Preadolescents with a PHA+ for both parents had blunted activity in reward anticipation, conferring a unique risk not seen in youth with only one parent with problematic alcohol use, or in youth with a PH of drug use. Future research should attempt to disentangle both genetic and environmental factors that may explain these discrepancies in reward processing, as well as the protective factors that may mitigate it. The current study found no interaction between PHA+ and time, suggesting that during preadolescents, the pattern of reward functioning remains consistent, but future work should assess if this pattern holds up across adolescence

Gulf War (GW) veterans were exposed to many neurotoxicants during the 1990-1991 Gulf War. Neurotoxicants included: chemical warfare such as sarin nerve gas, combustion byproducts from oil well fires and diesel fuels from tent heaters, pesticides, and prophylactic anti- nerve gas pyridostigmine bromide pills (PB); all of which have been associated with both cognitive and mood concerns. There are few longitudinal studies that have examined cognitive functioning regarding these toxicant exposures. In our longitudinal Fort Devens cohort, we found decrements over time in the area of verbal learning and memory but no differences in measures of nonverbal memory and executive function. To describe changes more accurately over time in this GW veteran cohort, we examined cognitive functioning in those with probable Post-Traumatic Stress Disorder (PTSD) versus those without.

The FDC is the longest running cohort of GW veterans with initial baseline cognitive, mood, exposure and trauma assessments in 1997-1998 and follow-up evaluations in 2019-2022. FDC veterans (N=48) who completed both time points were the participants for this study. Veterans were categorized into dichotomous (yes/no) groups of PTSD classification. The PTSD checklist (PCL) was used to determine PTSD case status. Symptom ratings on the PCL were summed (range:17-85) and a cutoff score of 36 or higher was utilized to indicate probable PTSD. Neuropsychological measures of mood (POMS) and memory (Visual Reproductions from the Weschler Memory Scale-R; California Verbal Learning Test Second Edition; CVLT2) and executive function and language; (Delis-Kaplan Executive Function System- Color Word and Verbal fluency- Animals) were compared overtime using Paired T-tests.

The study sample (N=48) was 92% male and 96% reported active-duty status at the time of the GW. Mean current age was 58 years. All veterans reported exposure to at least one war-related toxicant. 48% met criteria for probable PTSD (N = 23) while 52% did not (n=25). No differences between groups were found in any of the POMS subscales, nor were differences seen in verbal memory, executive function, or language tasks. There were, however, significant differences in nonverbal memory in those with probable PTSD showing fewer details recalled during delay on the WMS-R Visual Reproductions (p<0.05).

In this longitudinal analysis, GW veterans with PTSD showed declines in nonverbal memory and consistent levels of function in all other tasks. Basic mood scales did not show decline; therefore, these results are not due to generalized changes in mood. All participants reported at least one neurotoxicant exposure and we did not have the power to examine the impact of the individual exposures, thus we cannot rule any contributing factors other than PTSD. This study highlights the importance of longitudinal follow up and continual documentation of GW veterans’ memory performance and their endorsement of mood symptoms overtime. Specifically, these findings reveal that future studies should examine the prolonged course of memory and mood symptomatology in GW veterans who have endorsed a traumatic experience.

Memory complaints have been a concern of Gulf War (GW) veterans since their return from the war in 1991, and over time it has been reported that exposures to neurotoxicants during the war have been associated with memory decline from premorbid levels. However, many of the studies that have shown slight or no memory decrements only looked at one time point and have not followed participants to document trajectory of symptoms over time. Longitudinal design is an optimal way to document change in cognitive function over time and the Fort Devens cohort (FDC), the longest running cohort of GW veterans, is ideal for assessing such change. This prospectively designed non-treatment seeking cohort were assessed at multiple timepoints with neuropsychological assessments and surveys. Initial neuropsychological assessments from 1997 showed above average scores on tests of verbal memory (California Verbal Learning Test) and average nonverbal memory (Wechsler Memory Scale-R) performances. A follow-up study of neuropsychological testing was completed between 2019-2022. This study was designed to document change in cognitive status between the two time points.

Participants (N=50) from the original 1991 cohort were again tested from 2019-2022. Neuropsychological tests included California Verbal Learning Test-Second edition (CVLT2) for verbal learning, and the visual reproduction subtest from the Wechsler Memory Scale-Revised (WMS-R) for nonverbal learning and memory. For both time points, the average scores of the participants were compared with age scaled scores for each neuropsychological test.

The mean age of our current participants was 58 years. 72% were men. Relative to standardized test norms at the first time point, the scores for total learning from trials 1 through 5 from the CVLT2 were in the above average range relative to age and gender-based norms. During the second time point, the participants average scores on the same scale had dropped to the average range, one full standard deviation below their prior performances. In addition, at the first time point, total learning from visual reproductions was in the average range and dropped to the low average range for the second time point. This value dropped by one-half a standard deviation.

Results showed significant diminishment in verbal and visual memory relative to prior test performances. Whenever possible, documenting the trajectory of symptoms relative to where each participant started on neuropsychological functional outcomes is key to understanding the longitudinal impact of neurotoxicant and other war-related exposures in military veterans. Given this decline, further assessment of GW veterans’ cognitive trajectories is warranted.

People with Korsakoff syndrome (KS) experience severe neuropsychological and neuropsychiatric complications following vitamin B1 deficiency predominantly due to alcoholism. KS often presents itself with neuropsychological symptoms such as problems in episodic memory, executive functioning, and social cognition. Common neuropsychiatric symptoms in KS are disorders of affect, confabulations, anosognosia, and apathy. Apathy can be defined by a pathological lack of goal-directed behaviors, goal-directed cognitions, and goal-directed emotions. Patients with KS have an increased risk of cerebrovascular comorbidity. Cerebrovascular accidents are known to increase the risk for developing apathy. Apathy in KS patients can negatively influence the ability to live an autonomous life, often making 24-hour care a necessity. Limited research on apathy in KS patients has been published to this day. Our aim was to assess apathy in Korsakoff patients with and without neurovascular comorbidity.

General apathy and related subconstructs, such as judgment and decision-making skills, emotional blunting, and the intentions to perform pleasurable activities, were studied in fifteen KS patients, fifteen KS patients with additional cerebrovascular comorbidity, and fifteen healthy controls. The first responsible caregiver of each patient filled in the Apathy Evaluation Scale and Scale for Emotional Blunting. An examiner administered the interview-based Judgement scale of the Neuropsychology Assessment Battery with the KS patients and each KS patient filled in the self-report section of the Pleasurable Activities List. Both KS patient groups receive 24-hour care in a specialized facility for Korsakoff Syndrome.

Our study found higher levels of general apathy in both KS patient groups, when rated by their caregiver compared to healthy controls. No difference was found between the KS patient groups and the healthy control group on the self-reported section of the Pleasurable Activities List, which might suggest the presence of intrinsic motivation in KS patients. However, a discrepancy was found between the self-reported activity levels and proxy reported levels of apathy. KS patients with cerebrovascular comorbidity showed increased levels of emotional blunting compared to KS patients without cerebrovascular comorbidity and healthy controls. Decreased judgment and decision-making skills were found in both patient groups compared to healthy controls, with no difference found between KS patients with cerebrovascular comorbidity and KS patients without.

Our findings suggest that people with Korsakoff syndrome experience more general apathy compared to healthy controls. Both patient groups showed decreased judgement and decision-making skills and increased emotional blunting. Intrinsic motivation was found to be intact in KS patients. Experiencing cerebrovascular comorbidity in KS carries a risk for developing emotional blunting. Our findings show that apathy greatly affects people with KS. Future scientific research is warranted to further benefit the care for this complex patient population.

Prior literature has documented how motives for cannabis use predict frequency of use and cannabis use problems among adolescents. However, few studies have examined possible moderating variables that may influence the association between cannabis use motives and frequency of use. The current study examines how risky decision-making moderates this association to help better understand which individuals are at greater risk for cannabis use escalation. The current study will be the first to examine the interactive effects of motives for cannabis use (i.e., health or recreational reasons) and risky decision-making on cannabis use trajectories among a sample of adolescent cannabis users.

Data from 194 adolescent cannabis users aged 14–17 at baseline were analyzed as part of a larger longitudinal study. Participants included those who self-reported use of cannabis within six months prior to the baseline assessment. The Marijuana Reasons for Use Questionnaire (MJRUQ) was used to assess motives for cannabis use from a list of 13 items. A confirmatory factor analysis identified “health” and “recreational” factors for motives for cannabis use. Lifetime frequency of cannabis use (number of days used) was assessed through the Drug Use History Questionnaire, while risky decision-making was assessed using the Game of Dice Task. We used latent growth curve modeling and linear regression analyses to examine the interactive effects of motives for cannabis use and risky decision-making on initial levels of lifetime cannabis use at baseline, and rate of cannabis use escalation over time.

No significant interactive effects were found for health motives for cannabis use; however, we found significant main effects of health motives on initial levels of lifetime cannabis use at baseline (b = 100.82, p < .01) and rate of cannabis use escalation (b = 24.79, p < .01). Those with a greater proclivity to use cannabis for health purposes showed higher initial levels of lifetime use at baseline and steeper increases in the rate of cannabis use escalation relative to those less likely to use for health purposes. Furthermore, we found a significant interactive effect of recreational motives for use and risky decision-making on the rate of cannabis use escalation (b = -2.53, p < .01). Follow-up analyses revealed that among those less likely to use cannabis for recreational purposes, higher risky decision-making was associated with a steeper increase in the rate of cannabis use escalation relative to those who exhibited lower risky decision-making.

The current study replicated findings suggesting that cannabis use motives influence cannabis use trajectories. We found that using cannabis primarily for health reasons was associated with higher initial levels and steeper increases in use regardless of decision-making. Furthermore, we found that both motives for use and risky decision-making interacted to influence associations with cannabis use trajectories. Specifically, among individuals reporting less cannabis use for recreational reasons, those with relatively riskier decision-making showed steeper increases in the rate of cannabis use escalation. These findings inform prevention and intervention practices that focus on decision-making by tailoring approaches based on an individual’s primary motives for cannabis use.

Emotion regulation and functioning have well established links to substance use in adolescents. Yet limited research has investigated emotion regulation in very early substance initiators either on self-report or on behavioral measures (i.e., Emotional Stroop). Similarly, there are few prospective investigations of emotional functioning as a predictor of initiation. Given concerns of emotion difficulties preceding and predicting substance use onset, we aim to investigate emotional functioning difficulties in very early (ages 9–13) substance use initiators relative to sociodemographically matched controls, both after initiation and as a predictor of initiation. We hypothesize that initiators would demonstrate greater emotion dysregulation and decreased emotional functioning relative to controls.

ABCD Study Annual Release 4.0 was used. Participants included those who had data available at Y3 follow-up visit and youth-reported use of any full dose of a substance (n=148). Sociodemographic controls were then matched (n=148). General linear mixed effects models were run to assess emotional functioning at Y3 (Emotional Stroop response time and accuracy performance, youth-reported Emotion Regulation Questionnaire, and parent-reported Difficulties in Emotion Regulation Scale and Child Behavior Checklist externalizing and internalizing symptoms) by substance use group status controlling for random effects of family. Further, hierarchical linear models assessed CBCL emotional functioning from Y0 to Y3 predicting SU initiation at Y3, controlling for within-subject change.

At Y3, early substance use initiation predicted higher parent-reported externalizing symptoms significantly (estimate=5.88, p<.001). Substance use initiation also marginally predicted high parent-reported internalizing symptoms (estimate=2.29, p=.08) and DERS (estimate=0.02, p=.07). ERQ and Stroop performance were not significantly associated with group status (p's>.10). For externalizing symptoms predicting SU initiation, regardless of year (baseline through Y3) was significantly predictive of initiation (p's<.001). HLM demonstrated that externalizing symptoms at all time points resulted in the best predictive model (AIC=392.85, BIC=422.80, relative to models including all data through Y2, AIC=433.63, BIC=458.59).

Here we found externalizing symptoms and, to a lesser extent, internalizing symptoms and emotion dysregulation are associated with early substance use initiation. However, results are limited to parent report, despite the consideration of youth-report and a behavioral measure of emotion regulation, the Emotional Stroop task. Further, while marginal effects were found, downstream externalizing symptoms were a better predictor of later substance use initiation. While other metrics of emotion regulation have been linked to substance use in adolescence, emotion regulation abilities may change as a result of substance use, rather than a predictor of use, and thus needs monitoring over time.

Emotion regulation is generally thought of as the process of overriding one's initial emotional response to personally relevant events. One frequently investigated type of emotion regulation is cognitive reappraisal, which describes one's ability to cognitively alter the meaning of an event. Cognitive reappraisal is associated with better cognitive, social, and health outcomes compared to other emotion regulation strategies. The cognitive building blocks of cognitive reappraisal are related to executive cognitive control processes, which broadly describe one's ability to engage in non-automatic and goal-oriented behaviors. Crucially, executive control processes are also relevant in demanding cognitive tasks such as prospective memory since, similarly to cognitive reappraisal, they involve effortful and purpose driven efforts. However, cognitive reappraisal has thus far not been investigated regarding prospective memory performance despite findings that suggest that emotionally evocative stimuli improve prospective memory performance. The present study investigated whether cognitive reappraisal state and trait measures as well as other types of emotion regulation strategies are associated with prospective memory accuracy of negatively valenced prospective memory targets.

A total of 45 participants (69% women; M = 22.62 years, SD = 5.69 years) took part in this cross-sectional study. Cognitive reappraisal and prospective memory tasks were administered on the computer. A total of 106 pictures were shown in the prospective memory task, including 12 prospective memory hits. A 2-back paradigm was used as the effortful ongoing task. Dependent measures included accuracy of and reaction times to negative prospective memory hits. A total of 45 pictures were shown in the cognitive reappraisal task. Participants were asked to decrease their negative emotions when looking at previously normed negatively valenced pictures versus merely looking at them (Lang et al., 2001). Dependent measures in the cognitive reappraisal task included success of downregulating negative emotion after the DECREASE versus LOOK instruction. A mood manipulation check and a questionnaire asking about participants' reappraisal strategies was conducted. Trait based measures of emotion regulation included the Emotion Regulation Questionnaire and the Dysfunction of Emotion Regulation Scale.

Participants endorsed significantly higher negative mood after looking at negative versus neutral pictures, t(48) = 22.77, p , .05). Ratings further indicated that participants were able to significantly decrease how negative they felt when reappraising versus looking at negative pictures, t(44) = 12.82, p , .05. Regarding the relationship between prospective memory accuracy of negatively valanced prospective memory targets and cognitive reappraisal ability, no significant bivariate correlation was found (p > .05). However, a significant bivariate correlation was found between reaction times to negatively valenced prospective memory targets and cognitive reappraisal ability (rs = -.32, p = .03). No significant relationship was observed between prospective memory accuracy of or reaction times to negatively valenced prospective memory targets and trait based measures of emotion regulation (all ps > .05).

Hypotheses were partly supported. Higher state-based cognitive reappraisal abilities may be associated with lower cognitive costs when asked to remember negatively evocative pictures and/or higher overall cognitive capacity. The importance of assessing emotion regulation when utilizing emotionally evocative stimuli and their clinical significant is discussed.

Cognitive reappraisal is a frequently researched emotion regulation strategy. It broadly describes one's ability to alter or reinterpret the meaning of personally relevant events. Cognitive reappraisal is robustly associated with lower self-reported negative affect, lower physiological arousal, and higher positive affect, which is the reason why it is a key component of many psychotherapeutic interventions. However, little research to date has investigated different types of cognitive reappraisal tactics and their association with cognitive reappraisal success. Given that there are an arguably indefinite number of ways to reappraise personally relevant events, it would be clinically informative to identify those tactics that are associated with the greatest decline in negative emotionality. The current study investigated whether one's predominant use of a specific reappraisal strategy is associated with divergent cognitive reappraisal success.

A total of 42 participants (67% women; M = 23.33 years, SD = 6.05 years) took part in this cross-sectional study. Cognitive reappraisal was administered via a computerized task modeled after McRae et al. (2012). A total of 45 previously normed pictures were shown in the cognitive reappraisal task (Lang et al., 2001). Participants were asked to either decrease how they felt or look at negatively evocative images. The dependent measure was success of downregulating negative emotion after the “decrease” versus “look” instruction (i.e., cognitive reappraisal success). A mood manipulation check, a questionnaire asking about participants' reappraisal strategies, and frequency of each reappraisal tactic was conducted after the task was completed to ensure that participants implemented the task as intended. Reappraisal tactics were rated by 3 independent raters individually according to a previously established rating tactic coding system (McRae et al., 2012). An analysis of variance was conducted comparing reappraisal success across groups of the reappraisal tactic most frequently used for each participant. Additionally, total number of reappraisal strategies used was included as a covariate.

Participants endorsed significantly higher negative mood after looking at negative versus neutral pictures, t(41) = 22.70, p < .05). Ratings further indicated that participants were able to significantly decrease how negative they felt when reappraising versus looking at negative pictures, t(41) = 11.95, p < .05. On average, participants' most frequently used reappraisal tactic was used 50.54% (SD = 16.32) of the time. Descriptive statistics on frequency of reappraisal tactics across participants is shown. Regarding the analysis of variance of divergent reappraisal success based on tactic, no significant relationship was found (p > .05). The inclusion of number of reappraisal strategies per participant did not impact the results (p > .05).

The present study did not show a significant difference between reappraisal tactics regarding their cognitive reappraisal success. This replicates past findings and indicates that type of reappraisal tactic used may be not as impactful as using cognitive reappraisal in some fashion. However, reappraisal tactics were not distributed equally across participants. Future studies should include larger samples to attain adequate sample sizes for each reappraisal tactic. Furthermore, participants should be instructed to use a specific reappraisal tactic alongside their self-selected reappraisal preferences to gain insight into the relative success of different reappraisal tactics. Clinical relevance of present findings is discussed.

We measured sex differences in emotion regulation (ER) abilities – relying on exercise of cognitive reappraisal – during an image rating task in adults over 55 years of age with varying degrees of depression symptom severity. We also collected a self-report measure on participants' views of their own ER capacities. Previous research by this group has demonstrated the importance of emotion processing in the context of sex and aging in depression. We hypothesized that females would (1) score higher on the Cognitive Reappraisal Facet of the ERQ, (2) be more successful in utilizing cognitive reappraisal skills in response to negative stimuli; and (3) have self-report scores on the ERQ that more closely match their success at cognitive reappraisal than would males.

capacities. Previous research by this group has demonstrated the importance of emotion processing in the context of sex and aging in depression. We hypothesized that females would (1) score higher on the Cognitive Reappraisal Facet of the ERQ, (2) be more successful in utilizing cognitive reappraisal skills in response to negative stimuli; and (3) have self-report scores on the ERQ that more closely match their success at cognitive reappraisal than would males.

Only the first of our three outcome measures was successfully predicted by the model including age, MADRS scores, and sex as predictors. Scores on the ERQ cognitive reappraisal facet with sex accounted for 11.3% of the variance (F=7.344, p=.009). Age and depression symptom severity did not reach significance. Performance on the ERT itself and the correlation between the two were not meaningfully modeled.

Women showed both better cognitive reappraisal abilities overall and more insight into the level of those abilities, findings that fall in line with most ER literature. However, we found that females were also more likely than males to be skewed in the positive or “overconfident” direction; to overestimate those same abilities. This information is useful for clinicians interpreting self-report information in the emotion regulation domain. These findings may not generalize to a more diverse (racially and socioeconomically) population and given the cognitive nature of the reappraisal strategy; these results may not extend to a less educated population. These data will be useful to inform the interpretation of fMRI images from this same experiment.

Youth with attention-deficit/hyperactivity disorder (ADHD), characterized by symptoms of inattention and hyperactivity, often experience challenges with emotion regulation (ER) and/or emotional lability/negativity (ELN).1-3 Prior work has shown that difficulties with ER and ELN among young children contribute to lower academic achievement.4-6 To date, research examining associations between ADHD and academic achievement have primarily focused on the roles of inattentive symptoms and executive functioning.7-8 However, preliminary work among youth with ADHD suggests significant associations between disruptions in emotional functioning and poor academic outcomes.9-10 The current study will examine associations between ER, ELN, and specific subdomains of academic achievement (i.e., reading, spelling, math) among youth with and without ADHD.

Forty-six youth (52% male; Mage=9.52 years; 76.1% Hispanic/Latino; 21 with ADHD) and their parents were recruited as part of an ongoing study. Parents completed the Disruptive Behavior Disorders Rating Scale11 and Emotion Regulation Checklist12 about their child. Youth completed the Wechsler Abbreviated Scale of Intelligence-II13 and three subtests [Spelling (SP), Numerical Operations (NO), Word Reading (WR)] of the Wechsler Individual Achievement Test-III.14 Univariate analysis of variance assessed differences in emotional functioning and academic achievement among youth with and without ADHD. Correlation and regression analyses were conducted to examine the association between emotional factors and the three subtests of academic achievement.

Youth with ADHD exhibited significantly higher ELN (M=30.7, SD=8.7) compared to their peers (M=23.2, SD=5.8), when controlling for child age, sex, and diagnoses of conduct disorder and/or oppositional defiant disorder [F(1,41)=8.96, p<.01, ŋp2=.18]. With respect to ER, youth with (M=24.8, SD=4.2) and without ADHD (M=25.8, SD=4.3) did not differ [F(1,41)=.51, p=.48]. Surprisingly, within this sample, ADHD diagnostic status was not significantly associated with performance on any of the academic achievement subtests [WR: F(1,41)=.29, p=.59; NO: F(1,41)=.91, p=.35; SP: F(1,41)=2.14, p=.15]. Among all youth, ER was significantly associated with WR (r=.31, p=.04) and SP (r=.35, p=.02), whereas ELN was associated with performance on NO (r=-.30, p=.04). When controlling for child age, sex, IQ, and ER within the full sample, higher ELN was associated with lower scores on the NO subtest (b=-.56, SE=.26, p=.04). The associations between higher ER and WR scores (b=1.12, SE=.51, p=.03), as well as higher ER and SP scores (b=1.47, SE=.56, p=.01), were significant when controlling for child age and sex, but not ELN and IQ (p=.73 and p=.64, respectively).

As expected, youth with ADHD had higher ELN, although they did not differ from their peers in terms of ER. Results identified distinct associations between ER and higher reading/spelling performance, as well as ELN and lower math performance across all youth. Thus, findings suggest that appropriate emotional coping skills may be most important for reading and spelling, while emotional reactivity appears most salient to math performance outcomes. In particular, ELN may be a beneficial target for intervention, especially with respect to improvement in math problem-solving skills. Future work should account for executive functioning skills, expand the academic achievement domains to include fluency and more complex academic skills, and assess longitudinal pathways within a larger sample.

Adaptive emotional regulation strategies, such as cognitive reappraisal, are related to better neuropsychological functioning in the general population. Individuals with PTSD demonstrate difficulty with both emotional regulation and cognitive performance that contribute to clinical presentation (e.g., negative mood, irritability). However the extent to which neuropsychological functioning is associated with emotion regulation, alone and in concert with common comorbid symptoms like depression, remains understudied in this population. Better understanding how specific neuropsychological functions relate to cognitive reappraisal could point to novel treatment targets given preliminary evidence that certain cognitive training techniques can improves neuropsychological and affective outcomes. The present study aims to investigate the relationship between clinical symptoms of PTSD and depression, working memory capacity, and cognitive reappraisal in Veterans with PTSD. We hypothesized that clinical symptoms and working memory capacity would interact to predict cognitive reappraisal, such that elevated depression would relate to worse cognitive reappraisal, particularly for individuals with poor working memory capacity.

Measures of working memory (symmetry span task), mental health symptomatology (Clinician-Administered PTSD Scale for DSM-5 (CAPS-5) and Beck Depression Inventory-II (BDI-II), and emotional regulation (Emotion Regulation Questionnaire (ERQ)) were collected in 38 Veterans. A regression analysis was conducted with total CAPS score, total BDI score, total symmetry span score, and the interaction between BDI score and symmetry span score as the independent variables and total ERQ cognitive reappraisal score as the dependent variable.

When examining each predictor independently, cognitive reappraisal was not associated with working memory (t=1.42, p=.165), but was significantly associated with PTSD (t=-3.17, p<.003) and depressive (t=-4.15, p<.001) symptom severity. The multiple regression model (F(4, 35)=4.45, p<.005, R2=.26) did not support the hypothesized relationship between working memory and depressive symptoms (t=0.56, p=.579). Depression independently predicted utilization of cognitive reappraisal in veterans with PTSD (t=2.43, p=.020) but PTSD symptom severity and working memory scores did not. However, additional investigation revealed that independently, greater PTSD symptom severity did predict less utilization of cognitive reappraisal (t=-3.17, p<.005).

While depressive symptoms did not moderate the relationship between working memory and cognitive reappraisal, depressive symptoms did best predict utilization of cognitive reappraisal in a population with PTSD. Contrary to the hypothesized outcome, neither working memory nor PTSD symptoms were significant predictors of cognitive reappraisal when controlling for depressive symptoms. This suggests that the phenomenon of lower cognitive reappraisal rates in individuals with PTSD may be due to the presence of depressive symptoms rather than traumatic stress symptoms or neuropsychological ability. Due to the sample size and homogeneous diagnosis of the current study it is possible that the predicted relationship between working memory, PTSD severity, and cognitive reappraisal was not observed due to low power or a restricted range. Further investigation specifically in clinical populations on factors that predict utilization of cognitive reappraisal could expand on these findings in populations experiencing other stress-based disorders.

Combat exposure is associated with higher rates of depressive symptoms, including anhedonia (i.e., a reduced ability to seek and experience rewards) and feelings of social disconnectedness. While these symptoms are commonly documented in combat-exposed Veterans following deployment, the cognitive mechanisms underlying this pathology is less well understood. Computational modeling can provides detailed mechanistic insights into complex cognition, which may be particularly useful to understand how social reward processing is altered following combat exposure. Here, we use a Bayesian learning model framework to address this question.

Thirty-three Operation Enduring Freedom (OEF)/ Operation Iraqi Freedom (OIF)/Operation New Dawn (OND) Veterans (25 Male, 8 Female) between the ages of 18-65 years old (M = 41.61, SD = 10.49) participated in this study. In both classic/monetary and social reward conditions, participants completed a 2-arm bandit task, in which they must choose on each trial between two options (i.e., slot machine vs social partner) with unknown reward rates. While they received monetary outcomes in the classic condition, participants received compliments from different fictitious partners in the social condition. We first compared a learning-independent Win-stay/Lose-shift (WSLS) heuristic and either a Rescorla-Wagner Q-learning or a Bayesian learning model (Dynamic Belief Model/DBM) paired with a Softmax reward maximization policy. DBM+Softmax provided the best fit of the data for most participants (31/33). Individual DBM parameters of prior reward expectation, reward learning (i.e., perceived stability of reward rates), and Softmax reward maximization were estimated and compared across conditions.

Participants did not differ in their reward learning parameters across monetary and social conditions (t(30)= -0.70, p = 0.490), suggesting similar perception of reward stability in both modalities. However, higher Bayesian prior mean (i.e., initial belief of reward rate; t(30)= -2.31, p = 0.028, d=0.42) and greater reward maximization (i.e., Softmax parameter; t(30)= -2.26, p = 0.031, d=0.41) were observed in response to social vs monetary rewards. In the social reward condition, higher self-reported social connectedness was associated with greater model fit of our DBM model (i.e., smaller Bayesian Information Criterion/BIC; r = -0.38, p = 0.041). In this condition, those expecting higher reward rates when initiating reward exploration (those with higher DBM prior mean) endorsed lower self-esteem (Spearman's ρ = -0.43, p = 0.078) and lower positive affect (ρ = -0.32, p = 0.078).

A Bayesian learning modeling framework can characterize mechanistic differences in the processing of social vs non-social reward among combat-exposed Veterans. Individuals with higher social connectedness were more model-based in their performance, consistent with the notion that they are more likely to estimate and anticipate how much social peers have to offer. Combat-exposed individuals with lower self-esteem and positive affect appear to have higher initial expectations of reward from unknown partners, which could reflect greater need for mood and/or self-esteem repair in those individuals. Overall, Bayesian modeling of social reward behavior provides a useful quantitative framework to predict clinically relevant construct of functional outcomes in military populations.

To find how healthy college going participants SRS were affected by a customized Mind Body Intervention (MBI).

We performed a customized online tele-video course based MBI incorporating mindfulness and awareness training over a period of one month in 2021 to MBA students attending the Indian Institute of Management (IIM). Each subject was their own control. We used the World Health Organization Quality of Life Scale (QO-BREF) social relationship sub-scores pre and post intervention to assess participant SRS.

277 MBA students from the IIM with a mean age of 26.89 ± 1.7 were analyzed. Of the 277 students, 90 (32.49%) were female. The MBI decreased the self-perceived Social Relationship score among 277 graduate students. The mean SRS before the intervention was 7.51 ± 1.7 while the mean SRS after was 6.9 ± 1.7. Univariate paired t-test showed a significant mean difference (t = 5.1, p<.001). On a multivariate linear-regression model, the SRS change estimate was 0.46, t-value was 9.3, p < 0.001; 95% confidence interval was 0.37 - 0.56; p-value <0.001.

An online tele-video based customized Mind Body Intervention decreased the self-perceived social relationship score among graduate students at the IIM during the Covid-19 pandemic.

The increasing complexity of social stress may be especially threatening to mental health during childhood and adolescence. One's skills in effectively coping with this stress may contribute to symptoms of pediatric anxiety and depression, a growing, significant, and pervasive public health concern. In addition to strategic skills, individual differences in coping may reflect differences in brain structure, including the white matter pathways that integrate frontal lobe networks with those involved in social functioning. Identifying the neurological substrates underlying anxiety and depression is an important way to delineate mechanisms underlying development of these disorders. Deterministic automated-fiber quantification (AFQ) is a technique that removes potential error from manual tracking of white matter, segregating tracts into distinct nodes—diminishing the effect of crossing fibers—and quantifying the number of fibers in a tract, allowing for assessment of connectivity across regions. Collectively, this investigation aims to quantify the interplay between anxiety, depression, coping with social stress, and white matter microstructure in children and adolescents.

Ninety-two healthy children and adolescents (8-17 years old; n=53 female, Mage=12.96; n=39 male, Mage=12.31) and a parent rated symptoms of anxiety and depression using the Behavior Assessment System for Children (BASC-III). Coping and stress reactivity were assessed using the Responses to Stress Questionnaire, Social Stress version. Children and adolescents also completed 64-direction DTI in a Siemens 3T Prisma scanner. White matter microstructure was quantified using AFQ; Fractional anisotropy (FA) values were extracted for 18 tracts, comprised of 100 nodes each.

Mean levels of parent- and self-reported anxiety and depression fell within the normative range, and children reported mild- to moderate social stress. Higher levels of social stress were associated with increased parent reported anxiety (r=.294, p=.002) and parent- and self-reported depression (r=.481, p<.001; r=.211, p=.034, respectively). Anxiety and depression were not significantly related to white matter microstructure; however, several specific links with coping were noted. Use of secondary control coping (e.g., cognitive restructuring) was associated with higher FA of the bilateral inferior fronto-occipital fasciculi (left IFOF r=.228, p=.027; right IFOF r=.299, p=.003) and left inferior longitudinal fasciculus (r=.269, p=.009); use of primary control coping (e.g., problem solving) was associated with higher FA of the bilateral uncinate fasciculi (left UF r=.216, p=.036; right UF r=.207, p=.045). Furthermore, use of primary and secondary control coping were associated with fewer symptoms of anxiety and depression, whereas greater use of disengagement coping (e.g., wishful thinking) was associated with more depressive symptoms.

These findings highlight links among white matter microstructure in tracts integrating frontal with temporal and occipital regions, and adoption of adaptive (i.e., primary and secondary control) coping responses. This may suggest that strong connections between brain regions supports more of a modulatory than a neglecting coping strategy. Finding also replicate extant literature on the ties between coping style and psychosocial distress. Given that coping responses are amenable to intervention, capitalizing on these brain-behavior links during ongoing neuromaturation is worthy of future research, with a goal of reducing symptoms of anxiety and depression via the brain's support of adaptive coping.

Multiple sclerosis (MS) is a persistent neuroinflammatory disease of the central nervous system that affects young adults, and is pathologically characterized by multiple and distributed focal white matter lesions, although they are characteristically located in periventricular regions. Cognitive impairment occurs in all clinical forms of the disease, with great variability and great impact on the quality of life of patients. Recent research indicates that in addition to cognitive and physical deficits, they also have deficits in social cognition, such as Theory of Mind. Although social cognition in patients with multiple sclerosis has begun to be studied in recent years, there is still little knowledge about its impact in the early stages of the disease, when the load of injuries is low and physical disability is not yet present. A series of 7 cases of patients diagnosed with MS in follow-up by the Multiple Sclerosis polyclinic of the Institute of Neurology of the Hospital de Clínicas is presented.

Clinically stable patients with no recent urges and no cognitive complaint were included. They were evaluated with the ACE-R screening test and Theory of Mind tests: Reading the mind in the eyes and Faux Pas tests.

All patients presented normal ACE results, without indicators of cognitive impairment and poor performance in the emotion reading test. In two cases, poor yields in Faux Pas were also found.

Social cognition has a great impact on quality of life, and there are indicators of involvement in early stages of the disease in which other typical cognitive deficits are not yet evident, and may constitute the first indicator of deterioration. The evaluation and early detection of deficits in social cognition could contribute to the treatment and quality of life of patients.

Accurate processing of facial displays of emotion is critical for effective communication. A robust literature has documented impairment in the ability to recognize facial affect in people with traumatic brain injury (TBI), but research is scarce about memory for facial affect. Disruptions in recognizing and remembering the emotions of others can undermine relationship quality and may result in psychosocial dysfunction. Importantly, the extant literature indicates that facial affect recognition dissociates from other cognitive abilities such that it is likely a distinct neuronal process. Thus, explicit measurement of affect recognition and memory for emotions may be critical for implementing and refining rehabilitation interventions. The present study examined the relationship between recognition and memory for emotions using a novel computerized task and explored its associations with other cognitive abilities.

Participants were adults who were neurologically healthy (n = 31) or had a history of moderate to severe TBI (n = 26). The battery included the novel Assessment of Facial Affect Recognition and Memory (AFARM), Cambridge Face Memory Test (face memory without emotion), Wechsler Test of Adult Reading, Rey Auditory Verbal Learning Test, Judgment of Line Orientation, Oral Symbol Digit Modalities, Digit Span, FAS, Animal Fluency, and the Affect Intensity Measure (experienced emotion). Spearman correlations examined the relationship of AFARM performance with the test battery. Logistic regression models examined whether immediate-delay (ID-EM) and long-delay face emotion-memory (LD-EM) accounted for unique variance in group membership beyond recognition accuracy of facial affect and memory for faces.

AFARM demonstrated relationships with neuropsychological and mood variables in the expected directions across and within groups, with the strongest associations observed for memory for verbal information (rs = .51 to .58) and processing speed (rs = .48 to .57). Consistent with traditional list-learning tests, ID- and LD-EM were highly correlated (r = .85). Experienced affect intensity was inversely associated with ID-EM (r = -.29) and LD-EM (r = -.38) but not with recognition accuracy (r = -.10). Logistic regression examining ID-EM was significant, χ2(3) = 26.05, p < .001, Nagelkerke R2 = .49. ID-EM accounted for unique variance in group status (p = .006; OR = 0.65) after accounting for recognition accuracy and face memory. Similarly, the model examining LD-EM was significant χ2(3) = 27.70, p < .001, Nagelkerke R2 = .43; LD-EM was significant after accounting for other variables (p = .017; OR = 0.69).

The findings are consistent with the hypothesis that memory for emotions represents a unique component of social cognition that is separate from recognition. Accuracy in identifying emotions, face recognition memory, and memory for emotions are strongly related but not wholly redundant processes. Consistent with prior literature, subjective experience of emotion had substantial effects on objective performance tasks, indicating that an individual's intense experience of their own emotions can disrupt sensitivity to the emotions of others. Future research should assess the extent to which memory for emotions relates to psychosocial outcomes such as the quality and quantity of interpersonal relationships.

Previous research suggests that individuals with isolated Agenesis of the Corpus Callosum (AgCC) have cognitive and psychosocial deficits including that of complex processing of emotions (Anderson et al., 2017) and their ability to verbally express emotional experiences (Paul et al., 2021). Additionally, research suggests individuals with AgCC show impaired recognition of the emotions of others (Symington et al., 2010), as well as diminished ability to infer and describe the emotions of others (Renteria-Vazquez et al., 2022; Turk et al., 2010). However, the nature of the empathic abilities of individuals with AgCC remains unclear in empirical research. Capacity for empathetic feelings and situational recognition in persons with AgCC were tested using the Multifaceted Empathy Test [MET] (Foell et al., 2018). We hypothesized that individuals with AgCC would have lower abilities for both cognitive and affective empathy than neurotypical controls.

Results from 50 neurotypical control participants recruited from MTurk Cloud were compared to responses from 19 AgCC participants with normal-range FSIQ (>80) drawn from the individuals with AgCC involved with the Human Brain and Cognition Lab at the Travis Research Institute. The research was completed through an online version of the MET. The MET uses a series of photographs of individuals displaying an emotion. To measure cognitive empathy, the participants are asked to pick the correct emotion being displayed with three distractors for each item. To measure affective empathy, they are then asked on a sliding scale, “how much do you empathize with the person shown” (1 = Not at all, 7 = Very much).

Results of a MANOVA showed a trend for a significant overall difference between individuals with AgCC and controls for empathic abilities F(1, 67) = 2.59, p-value = .082, with persons with AgCC showing less empathy overall. Follow-up one-way ANOVAs showed that individuals with AgCC scored significantly lower in cognitive empathy F(1, 67) = 4.63, p-value = .035, ηp2 = .065; however, affective empathy was not significantly different between groups F(1, 67) = .537, p-value = .466, ηp2 = .008.

Results suggest that adults with AgCC have a diminished ability to give cognitive labels to the emotional states of others compared to neurotypical controls. However, contrary to our hypothesis, participants with AgCC had affective responses to the pictures of the emotional states of others which were similar to neurotypical controls. Recent research has shown that individuals with AgCC have difficulty inferring and elaborating on the more complex cognitive, social, and emotional aspects of simple animations (Renteria-Vazquez et al., 2022; Turk et al., 2010). Cognitive empathy would require this form of elaborative thinking, even when affective empathy is normal. Similarly, Paul et al. (2021) described alexithymia in persons with AgCC as difficulty in expressing emotions linguistically, but found similar endorsements of emotional experience when compared to neurotypical controls. This study provides further evidence to suggest the corpus callosum facilitates the ability to cognitively label emotions but not necessarily the ability to experience emotions affectively.
