The study demonstrates that the modified TSST task can elicit an acute hypothalamic-pituitary-adrenal axis response, but the nature of this response is dependent upon participants' perceptions of language brokering (parental dependence and efficacy), parental hostility, and discrimination experiences. Adolescents' individual characteristics and contextual demands remain important considerations in understanding their acute stress responses.

Prior studies investigating the association between acculturation and adolescent adjustment have often focused on specific acculturation domains rather than examining these domains collectively in a profile typology. Here, we investigate stability and change patterns in Mexican American adolescent acculturation profiles over time, using a two-wave longitudinal dataset spanning 5 years. Using latent profile analysis, three adolescent acculturation profiles were identified at Waves 1 and 2: integrated; moderately integrated; and moderately assimilated. Using latent transition analysis, four acculturation transition profiles were identified across time: stable integrated; stable moderately integrated; progressive; and regressive. Over half of all adolescents were identified as belonging to the stable integrated and stable moderately integrated transition profiles. Adolescents classified in the stable integrated profile reported the highest levels of adjustment (academic competence and socioemotional well-being) relative to those with other transition profiles. Findings

Objective: Hormones are often conceptualized as biological markers of individual differences and have been associated with a variety of behavioral indicators and characteristics, such as mating behavior or acquiring and maintaining dominance. However, before researchers create strong theoretical models for how hormones modulate individual and social behavior, information on how hormones are associated with dominant models of personality are needed.Although there have been some studies attempting to quantify the associations between personality traits, testosterone, and cortisol, there are many inconsistencies across these studies.Methods: In this registered report, we examined associations between testosterone, cortisol, and Big Five personality traits. We aggregated 25 separate samples to yield a single sample of 3,964 (50.3% women; 27.7% of women were on hormonal contraceptives). Participants completed measures of personality and provided saliva samples for testosterone and cortisol assays.Results: The results from multi-level models and meta-analyses revealed mostly weak, nonsignificant associations between testosterone or cortisol and personality traits. The few significant effects were still very small in magnitude (e.g. testosterone and conscientiousness: r = -0.05). A series of moderation tests revealed that hormone-personality associations were mostly similar in men and women, those using hormonal contraceptives or not, and regardless of the interaction between testosterone and cortisol (i.e., a variant of the dual-hormone hypothesis).Conclusions: Altogether, we did not detect many robust associations between Big Five personality traits and testosterone or cortisol. The findings are discussed in the context of biological models of personality and the utility of examining heterogeneity in hormonepersonality associations.

Language brokering is a prevalent phenomenon in ethnic minority immigrant populations. Although accruing evidence points to the beneficial impacts of healthy role identity development, research investigating the formation of a language broker role identity in language brokering adolescents is lacking in the literature. In a sample of 604 Latinx adolescents (54.3% female; M age at Time 1 = 12.41, SD = .97), structured equation modeling was conducted with maternal warmth and hostility examined as antecedents and adolescents' life meaning as a mediator for language broker role identities. Results revealed that life meaning mediated the positive association from Lester Sim is a doctoral student in the Department of Psychology at the University of Michigan. His research interests include the study of close relationships, examining cross cultural differences and how identity may influence these processes.
