The purpose of the present study was to identify clinically relevant subtypes of aggressive children based on measures of children's self-systems and significant others' perceptions of relationship quality. In a sample of aggressive second- and third-graders, a cluster analysis of these children's perceptions of support and significant others' (mother, teacher, and peers) perceptions of relationship quality revealed one subgroup in which self- and other-ratings were both below the group mean (concordant-negative), one in which both were above the sample mean (concordant-positive), and one in which they were discrepant (high child-report and low other-report). All three clusters were rated as more aggressive than controls. However, children in the discrepant group were rated as considerably more aggressive and delinquent than those in the two concordant clusters, who did not differ from each other on measures of internalizing and externalizing behaviors. Results are discussed from an attachment perspective and in terms of the clinical significance of this self–other discrepancy.

A recent finding that individuals with autism are not susceptible to illusions has been explained by Happé (1996) as a sign of “weak central coherence” at lower levels of processing. We investigated the phenomenon with a more sophisticated measure. In Experiment 1, individuals with autism, Asperger's syndrome, moderate learning difficulties, and typical development adjusted certain comparison lines and circles to make them appear to be the same size in four visual illusions. With a minor exception, the participants with autism and Asperger's syndrome evinced a systematic bias in their judgements in the illusion condition. The extent of this was no different from control participants. In a second experiment, a similar finding was obtained in a task where participants made verbal judgements about the stimuli. The results suggest that lower-level coherence in visual processing in autism is intact.

Inferior auditory temporal processing has been postulated as causally linked to phonological processing deficits in disabled readers with concomitant oral language delay (LDRDs), and absent in specifically disabled readers with normal oral language (SRDs). This investigation compared SRDs, LDRDs and normal readers aged 7–10 years on measures of auditory temporal processing (temporal order judgement) and phonological decoding (nonword reading). LDRDs exhibited deficits in temporal order judgement compared with normal readers, from whom SRDs did not differ significantly. These findings suggest that auditory temporal processing and oral language are related; however, very large within-group variability in the auditory temporal processing data further suggests that this relationship prevails in only a proportion of disabled readers with concomitant oral language weakness. In nonword reading, LDRDs performed worst of all, but SRDs also exhibited significant deficits compared with normal readers. Taken together, our results preclude the conceptualisation of temporal processing deficits as the unitary cause of phonological and language deficits in disabled readers.

Do cultural values and traditions influence the development of coping styles? To address this question, we compared self-reports of coping by 6–14-year-olds in Thailand and the U.S. One hundred and forty-one children were interviewed about six common stressors: separation from a friend, injection in a doctor's office, adult anger, peer animosity, school failure, and physical injury. Children's self-reported coping methods were coded as overt or covert. Coping goals were coded as reflecting primary control (attempts to influence objective conditions), secondary control (attempts to adjust oneself to objective conditions), or relinquished control. Although findings revealed numerous cross-national similarities, there were also multiple main and interaction effects involving culture, suggesting that sociocultural context may be critical to our understanding of child coping. Consistent with literature on Thai culture, Thai children reported more than twice as much covert coping as American children for stressors involving adult authority figures (i.e. adult anger, injection in doctor's office). Thai children also reported more secondary control goals than Americans when coping with separation, but American children were five times as likely as Thais to adopt secondary control goals for coping with injury. The findings support a model of coping development in which culture and stressor characteristics interact, with societal differences most likely to be found in situations where culture-specific norms become salient.

The main aim of this study was to determine whether child mental health professionals who regularly use questionnaires to screen for mental disorders know that these questionnaires have a low predictive value when the base rate of a disorder is low. The study was based on a representative sample of professionals who used questionnaires regularly to screen for mental disorders. They were set a problem in which a clinic sample was screened with a questionnaire that, at a certain cut-point, had 80% sensitivity and 80% specificity, and in which the true base rate of disorder was 10%. Only 10% (5/48) of respondents answered correctly that just 30% of individuals who scored above this cut-point would actually have the disorder and more than half of respondents believed that 80% would have the disorder. Both users and designers of questionnaires need to be more aware of and explicit about their drawbacks as screens for mental disorders.

In order to examine the mechanism whereby stunted children have poor developmental levels, we compared the behaviour of stunted (N=78) and nonstunted (N=26) children aged 12 to 24 months, and examined the relationship of their behaviour to their developmental levels. The effect of nutritional supplementation with or without psychosocial stimulation on the stunted children's behaviour was also examined. The children were observed at home during 4 days over a period of 6 months. The stunted children showed significantly more apathy, and less enthusiasm and variety in exploring, were less happy and more fussy. Caretakers' vocalisations to them were less warm or instructive. Stunted children's activity level, exploratory and happy behaviours were predictive of change in developmental levels measured on the Griffiths Scales, from enrolment to 12 and 24 months later. Supplementation predicted mental age at 12 and 24 months after enrolment, however, it had no significant effect on behaviour.

This study was designed to test the prediction that adolescents with autism would have specific limitations in imitating the “style” of another person's actions. In a series of original tasks that tested the delayed imitation of novel nonsymbolic actions, 16 participants with autism and 16 nonautistic participants group-matched for age and verbal ability were proficient in copying goal-directed actions, but in 3 out of 4 tasks, strikingly fewer participants with autism imitated with style with which the demonstrator executed the actions. An additional finding was that on 2 conditions that involved copying self-orientated actions, only 5 of the participants with autism but 15 of the 16 nonautistic participants spontaneously adopted the orientation-to-self on at least 1 occasion. The results are discussed with reference to theories concerning imitation deficits in autism, and with regard to the proposal that autism involves an impairment in intersubjective contact between affected individuals and others (Hobson, 1989, 1993; Rogers & Pennington, 1991).

From a sample of middle-class mothers and their 3-year-old children, a selected group of 36 mothers were divided into 2 groups according to the quality of their responses to the Adult Attachment Interview as a Questionnaire (Crandell, Fitzgerald, & Whipple, 1997). Twenty mothers provided coherent accounts of their early parent–child relationships (secure) and 16 mothers provided idealised, entangled, or otherwise incoherent accounts of their early parent–child relationships (insecure). The mothers were administered an abbreviated version of the WAIS-R and the children were given an abbreviated version of the Stanford-Binet Intelligence Scale. The quality of mother–child interactions was assessed by videotaping a 20-minute play episode and clean-up period, and by rating the degree of synchrony according to a modified version of the Belsky Parent–Child Interaction System (Whipple, Denburg, & Davies, 1993). The results were that children of secure mothers scored 19 points higher on the Stanford-Binet test compared to children of insecure mothers. (The adjusted mean difference was 12 points when maternal IQ, education, and family SES were taken into account.) The group difference in the children's IQ remained significant when comparisons were made between a subgroup of 12 secure and 12 insecure mothers who were matched for maternal IQ. Finally we examined the subgroup of 16 cases where child IQ scores were either 10 points higher or lower than maternal IQ. In all 6 cases where child IQ was at least 10 points below maternal IQ, the child had a mother who was insecure; in contrast, only 4 of the 10 children who had IQ scores 10 points higher than maternal IQ had an insecure mother. In terms of parent–child interaction patterns, there was suggestive evidence that the degree of parent–child synchrony was also related to child IQ. The results suggest important social-developmental contributions to young children's performance on standardised tests of intellectual ability.

The goal of this study was to evaluate the effect of methylphenidate (MPH) and clonidine in comparison with placebo on response inhibition and state regulation in children with Attention Deficit Hyperactivity Disorder (ADHD). The study utilised a double-blind cross-over design in which children were randomly assigned without replacement to placebo, MPH, and clonidine following baseline assessment. The primary dependent measures were derived from children's performance (reaction time and errors) on a GO–NO GO task under three conditions that altered the inter-stimulus interval (ISI) for presented GO–NO GO stimuli: ISI of 1 sec (fast condition), 4 sec (medium condition), and 8 sec (slow condition). Findings indicated no difference in task performance between groups treated for 7 weeks with placebo, MPH, and clonidine. We concluded that the state regulation problem in ADHD is resistant to MPH and clonidine.

The role of attachment style, self-esteem, and relationship attributions as possible mediators between abusive childhood experiences and difficulties in establishing supportive love relationships in adulthood were investigated in a sample of women known to be at risk of experiencing relationship problems. Measures of child abuse, the quality of love relationships, and the three potential mediators were made concurrently in adulthood. Participants who had experienced child abuse were found to be six times more likely to be experiencing difficulties in the domain of adult love relationships than those who had not. Self-esteem and relationship attributions were not found to be related to child abuse. When both child abuse and avoidant/ambivalent attachment style were considered together avoidant/ambivalent attachment style, but not child abuse, was found to be related to relationship difficulties. These findings indicate that avoidant/ambivalent attachment style, but not self-esteem and relationship attributions, is a mediating factor in the route from child abuse to adult relationship abilities.

The relationships between maternal age (at birth) and educational and psychosocial outcomes at age 18 were examined in a birth cohort of 1025 New Zealand children. This analysis indicated the presence of consistent tendencies for increasing maternal age to be associated with declining risks of educational underachievement, juvenile crime, substance misuse, and mental health problems. Children with teenage mothers had risks of later adverse outcomes that were 1.5 to 8.9 times higher than the risks for offspring of mothers aged over 30. Subsequent analyses revealed that the associations between maternal age and later educational and psychosocial outcomes were largely, but not wholly, explained by associations between maternal age and the child-rearing practices and home environments experienced by children. In general, increasing maternal age tended to be associated with more nurturant, supportive, and stable home environments. In turn, these linkages between maternal and childhood environment explained most of the association between maternal age and later outcomes. The theoretical and applied implications of these results are considered.
