Two languages, historically related, both have lexical stress, with word stress distinctions signalled in each by the same suprasegmental cues. In each language, words can overlap segmentally but differ in placement of primary versus secondary stress (OCtopus, ocTOber). However, secondary stress occurs more often in the words of one language, Dutch, than in the other, English, and largely because of this, Dutch listeners find it helpful to use suprasegmental stress cues when recognising spoken words. English listeners, in contrast, do not; indeed, Dutch listeners can outdo English listeners in correctly identifying the source words of English word fragments (oc-). Here we show that Dutch-native listeners who reside in an English-speaking environment and have become dominant in English, though still maintaining their use of these stress cues in their L1, ignore the same cues in their L2 English, performing as poorly in the fragment identification task as the L1 English do.

Bilingual children have better Theory-of-Mind compared to monolingual children, but comparatively little research has examined whether this advantage in social cognitive ability also applies to adults. The current study investigated whether multilingual status and/or number of known languages predicts performance on a mentalizing task in a large sample of adult participants. Multilingualism was decomposed based on whether English is the first language or not. All analyses controlled for well-known predictors of mentalizing, such as gender, same-race bias, and years of English fluency. We found a U-shaped trend, such that monolinguals and multilinguals did not differ much in their mentalizing ability, but bilinguals performed worse than monolinguals. Our study builds upon past work by examining a large sample of participants, measuring a crucial aspect of adult social cognition that has previously been unexplored, controlling for several nuisance variables, and investigating whether multilingualism leads to additional benefits in mentalizing abilities beyond bilingualism.

Thirty-four English–Malay bilinguals of between four and six years of age (both balanced and dominant) characterized as low socioeconomic status (SES) on income and parental education were tested on the child-Attentional Network Task (child-ANT; Rueda, Fan, McCandliss, Halparin, Gruber, Lercari & Posner, 2004) measuring executive attention. Although SES measures fell below the Singapore median, Malay children's performance on the child-ANT remained high when compared to other age-matched monolingual and bilingual children previously tested with the child-ANT (Yang, Yang & Lust, 2011), and English–Chinese Singaporean bilinguals (Kang, 2009). None of the three SES measures – father's and mother's education, and income, significantly correlated with child-ANT components. Regression analyses confirmed that none of the SES measures significantly predicted performance on the child-ANT. Caregiver reports suggested that both balanced and dominant bilinguals displayed high executive control. We consider the possibility that cultural variations – simultaneous and pervasiveness of bilingualism in Singapore, or pervasive code-switching – may ameliorate potential negative effects of SES on executive control development.

It is well-known that native English speakers sometimes erroneously accept subject-verb agreement violations when there is a number-matching attractor (e.g., *The key to the cabinets were…). Whether bilinguals whose L1 lacks number agreement are prone to such interference is unclear, given previous studies that report conflicting findings using different structures, participant groups, and experimental designs. To resolve the conflict, we examined highly proficient Korean–English bilinguals’ susceptibility to agreement attraction, comparing prepositional phrase (PP) and relative clause (RC) modifiers in a speeded acceptability judgment task and a speeded forced-choice comprehension task. The bilinguals’ judgments revealed attraction with RCs but not with PPs, while reaction times indicated attraction with both structures. The results therefore showed L2 attraction in all measures, with the consistent exception of judgments for PPs. We argue that this supports an overall native-like agreement processing mechanism, augmented by an additional monitoring mechanism that filters explicit judgments in simple structures.

Both inhibitory control and typological similarity between two languages feature frequently in current research on multilingual cognitive processing mechanisms. Yet, the modulatory effect of speaking two typologically highly similar languages on inhibitory control performance remains largely unexplored. However, this is a critical issue because it speaks directly to the organisation of the multilingual's cognitive architecture. In this study, we examined the influence of typological similarity on inhibitory control performance via a spatial Stroop paradigm in native Italian and native Dutch late learners of Spanish. Contrary to our hypothesis, we did not find evidence for a differential Stroop effect size for the typologically similar group (Italian–Spanish) compared to the typologically dissimilar group (Dutch–Spanish). Our results therefore suggest a limited influence of typological similarity on inhibitory control performance. The study has critical implications for characterising inhibitory control processes in multilinguals.

Several studies on heritage language (HL) acquisition investigate a single linguistic structure, showing how language exposure or cross-linguistic effects affect its acquisition. Here, we consider HL speaking children's mastery of several linguistic structures using a cloze-test. We examine how their language competence is affected by language exposure variables and age. We tested 180 children between the ages of 8 and 16, living in Switzerland and speaking European Portuguese as HL and French, German or Italian as their societal language. The items of the cloze-test cluster around two levels of difficulty, with the items at the second level corresponding to structures that are acquired late in Portuguese monolingual acquisition. Older age and a greater amount of formal instruction in the HL lead to better performance. The role of the amount of formal instruction varies based on the level of difficulty of the target structures. Cross-linguistic influence does not affect the results.

This study investigated the effect of external non-linguistic cues on language selection in bilinguals. Participants viewed photographs and stated in which language they would speak to the individuals in those photographs via a button press. These images were manipulated such that external cues (the ‘speak Welsh’ logo, presented in the form of a poster or a lanyard) were present or absent. Participants responded faster and selected Welsh as their language of choice more often in trials that contained a language cue than in trials in which a language cue was absent. Furthermore, trials containing a lanyard had a greater effect on participant performance than trials containing a poster. These results suggest that external cues can influence language selection in bilinguals, and that the perceived reliability of the cue can modulate this effect. These findings have implications for the language selection literature and could inform the development of future language use interventions.

The study of the brains’ oscillatory activity has been a standard technique to gain insights into human neurocognition for a relatively long time. However, as a complementary analysis to ERPs, only very recently has it been utilized to study bilingualism and its neural underpinnings. Here, we provide a theoretical and methodological starter for scientists in the (psycho)linguistics and neurocognition of bilingualism field(s) to understand the bases and applications of this analytical tool. Towards this goal, we provide a description of the characteristics of the human neural (and its oscillatory) signal, followed by an in-depth description of various types of EEG oscillatory analyses, supplemented by figures and relevant examples. We then utilize the scant, yet emergent, literature on neural oscillations and bilingualism to highlight the potential of how analyzing neural oscillations can advance our understanding of the (psycho)linguistic and neurocognitive understanding of bilingualism.

Little is known about the effects of bilingualism and distributional properties of word relationships on children's development of semantic convergence, operationalized as children's ability to produce word associates that mirror adults’ responses in a word association task. Forty-five Mandarin–English bilingual, 32 Spanish–English bilingual, and 28 English-speaking monolingual children, aged 4 to 7, produced three associates to each of 15 single-word cues in English. Children's productions were compared against adult responses to the same cues in the “Small World of Words” Norm. Three scoring methods comparing similarities of children's responses to adults’ showed consistent bilingual disadvantages in producing adult-like responses. Follow-up analyses targeted the three most predominant responses adults produced for each cue and addressed factors predicting children's likelihood to produce these responses. Results showed additional effects of cue-associate relationships measured by co-occurrence and semantic relatedness. The findings highlight the multi-faceted nature of knowledge development of word relationship and semantic convergence.

Comprehenders predict what a speaker is likely to say when listening to non-native (L2) and native (L1) utterances. But what are the characteristics of L2 prediction, and how does it relate to L1 prediction? We addressed this question in a visual-world eye-tracking experiment, which tested when L2 English comprehenders integrated perspective into their predictions. Male and female participants listened to male and female speakers producing sentences (e.g., I would like to wear the nice…) about stereotypically masculine (target: tie; distractor: drill) and feminine (target: dress; distractor: hairdryer) objects. Participants predicted associatively, fixating objects semantically associated with critical verbs (here, the tie and the dress). They also predicted stereotypically consistent objects (e.g., the tie rather than the dress, given the male speaker). Consistent predictions were made later than associative predictions, and were delayed for L2 speakers relative to L1 speakers. These findings suggest prediction involves both automatic and non-automatic stages.

In Rethinking Multilingual Experience through a Systems Framework of Bilingualism (Titone & Tiv, 2022), we encouraged psycholinguists and cognitive neuroscientists to consider integrating social and ecological aspects of multilingualism into a collective understanding of its cognitive and neurocognitive bases (i.e., to rethink experience). We then offered a framework – the Systems Framework of Bilingualism – and described empirical challenges and potential solutions with applying this framework to new research. Since the paper's publication, several eminent colleagues read and commented on our Keynote, noting both its strengths and areas for improvement. We read each commentary with enthusiasm and gratitude. Here, we briefly respond to several salient points raised, which led us to clarify and improve our theoretical approach. We first address what the commentaries agreed were strengths of the framework. We follow this with a discussion of what the commentaries stated could be improved or extended. We conclude with ways that we modified our model to collectively address concerns raised in the commentaries.
