RESUMO

Theories of adolescent development suggest that elevated neural sensitivity to social evaluation confers tradeoffs for adolescents' wellbeing, promoting adaptation to changing social contexts but increasing risk for emotional distress and depression. This study investigated whether the association between neural processing of peer feedback and depressive symptoms depends on teacher-reported executive function (EF) ability in adolescent girls. Girls showed activation to negative and positive peer feedback in regions implicated in social-emotional processing that interacted with EF to predict depressive symptoms. Specifically, activation predicted more depression in youth with poorer EF but less depression in youth with better EF, suggesting that the impact of increased social sensitivity may depend on youths' ability to regulate this sensitivity in adaptive ways.

RESUMO

To examine whether need for approval (NFA) and antisocial behavior (ASB) moderate the effects of socioemotional stimuli on cognitive control, 88 girls (Mage  = 16.31 years; SD = 0.84; 65.9% White) completed a socioemotional Go/No-go and questionnaires. At high approach NFA, girls responded more slowly during appetitive than control (b = -8.80, p < .01) and aversive (b = -5.58, p = .01) trials. At high ASB, girls responded more slowly (b = -6.12, p = .02) and less accurately (OR = 1.11, p = .03) during appetitive than aversive trials; at low ASB, girls responded more slowly during aversive than control trials (b = -4.42, p = .04). Thus, both context and individual differences influence adolescents' cognitive control.

RESUMO

Exposure to peer victimization is a traumatic stressor, with adverse consequences for mental and physical health. This prospective, multi-method, multi-informant study investigated how victimization "gets into the brain," as reflected in neural dysregulation of emotion during adolescence. Moreover, we examined whether certain youth are particularly vulnerable to compromised neural function (i.e., a pattern of positive amygdala-right ventrolateral prefrontal cortex [rVLPFC] connectivity linked to poor emotion regulation [ER] and emotional distress) following victimization. In all, 43 adolescent girls completed an implicit ER task during a functional brain scan, and reported on rejection sensitivity. In 6th-9th grades, teachers and adolescents reported annually on victimization. Results revealed that a history of elevated victimization predicted less effective neural regulation of emotion (more positive amygdala-rVLPFC connectivity) in girls with high but not low rejection sensitivity. Consistent with a differential susceptibility model, high rejection sensitivity was associated with particularly effective neural regulation of emotion (more negative amygdala-rVLPFC connectivity) in girls with low-victimization histories. A parallel pattern emerged for a behavioral index of ER. This research provides insight into one pathway through which peer adversity undermines emotional development in ways that forecast compromised future health, and identifies youth who are at particularly high risk following peer adversity.

RESUMO

The purpose of this study was to investigate contributions of maternal emotional resources to individual differences in adolescents' functional connectivity during emotion regulation. Participants included 35 adolescent girls who completed an implicit emotion regulation task during fMRI. Mothers reported on the quality of their adult attachment and emotional awareness when youth were in elementary school. Higher anxious attachment and lower emotional awareness were significantly correlated with more positive amygdala-right ventrolateral prefrontal cortex connectivity, a pattern linked in prior research with ineffective emotion regulation and emotional difficulties. Further, there was an indirect effect of anxious attachment on adolescent connectivity through emotional awareness. These results suggest that compromised maternal emotional resources in childhood may be linked to atypical neural processing of emotions.

RESUMO

This research examined whether heightened neural activation to social cues confers adjustment advantages in supportive social contexts but adjustment disadvantages in stressful social contexts. Forty-five adolescent girls were exposed to social exclusion during an fMRI scan and reported on parent-child relationship quality and depressive symptoms. Stressful parent-child relationships predicted subsequent depressive symptoms in girls with high and moderate but not low dorsal anterior cingulate cortex, subgenual anterior cingulate cortex, and anterior insula activation during exclusion. In the context of supportive parent-child relationships, however, neural activation to exclusion predicted particularly low levels of depressive symptoms. This support for a biological sensitivity to context model suggests the possibility of redirecting adolescent girls' neural sensitivity to social cues toward more positive adaptation.

RESUMO

This study examines the interactive contribution of the hypothalamic-pituitary-adrenal (HPA) axis and approach-avoidance motivation systems to longitudinal changes in depressive symptoms across the adolescent transition. In the summer prior to, or fall of, 4th grade, 132 youth (68 girls; 64 boys; M age = 9.46 years) participated in a social challenge task and reported on their depressive symptoms. In the winter of 6th grade, youth completed a semi-structured interview of depression and a self-report measure of approach-avoidance motivations. Analyses revealed two profiles of risk for adolescent depressive symptoms, with some gender differences: (1) excessive disengagement, reflected in HPA underactivation along with low approach motivation or high avoidance motivation; and (2) excessive engagement, reflected in HPA overactivation along with high approach motivation. This research highlights the importance of a multi-system perspective on development, suggesting that the implications of HPA dysregulation for depressive symptoms are contingent on adolescents' tendencies toward approach versus avoidance.

RESUMO

Adolescence is a period of rapid biological and psychological development, characterized by increasing emotional reactivity and risk-taking, especially in peer contexts. Theories of adolescent neural development suggest that the balance in sensitivity across neural threat, reward and regulatory systems contributes to these changes. Building on previous research, this study used a novel social feedback task to explore activation and functional connectivity in the context of social threat and reward in a sample of mid-adolescent girls (n = 86, Mage = 16.32). When receiving negative peer feedback, adolescents showed elevated activation in, and amygdala connectivity with, social processing regions [e.g. medial prefrontal cortex (mPFC) and temporoparietal junction (TPJ)]. When receiving positive feedback, adolescents showed elevated activation in social and reward (e.g. mPFC and ventromedial prefrontal cortex) processing regions and less striatum-cerebellum connectivity. To understand the psychological implications of neural activation and co-activation, we examined associations between neural processing of threat and reward and self-reported social goals. Avoidance goals predicted elevated amygdala and striatum connectivity with social processing regions [e.g. medial temporal gyrus (MTG)], whereas approach goals predicted deactivation in social processing regions (e.g. MTG/TPJ and precuneus), highlighting the importance of considering individual differences in sensitivity to social threat and reward in adolescence.

RESUMO

Recent theories posit that emotion mindsets (i.e., the extent to which individuals believe emotions are malleable or fixed) play a crucial role in experiences of emotion and influence emotion regulation (ER) processes. Drawing from mindset theory, this study examined the hypothesis that fixed emotion mindsets (FEMs) would predict depressive symptoms via compromised ER competence in adolescence, a period when many first episodes of depression occur. Results supported these hypotheses across two studies assessing participants in midadolescence (ages 14-18; M age = 16.17) and late adolescence (ages 18-21; M age = 18.52). Using a comprehensive approach to assessing ER, results demonstrated that FEMs were associated with less voluntary engagement and more disengagement and emotion dysregulation. In turn, higher voluntary engagement was associated with lower depressive symptoms, whereas higher disengagement and emotion dysregulation were associated with higher depressive symptoms. These findings highlight that one understudied pathway from FEMs to depressive symptoms may be the manner in which individuals respond to their emotions, implicating emotion mindsets as one target for efforts to improve clinical outcomes during adolescence.

RESUMO

The adaptive calibration model suggests exposure to highly stressful or highly supportive early environments sensitizes the brain to later environmental input. We examined whether family and peer experiences predict neural sensitivity to social cues in 85 adolescent girls who completed a social feedback task during a functional brain scan and an interview assessing adversity. Whole-brain functional connectivity (FC) analyses revealed curvilinear associations between social experiences and FC between the ventral striatum and regions involved in emotion valuation, social cognition, and salience detection (e.g., insula, MPFC, dACC, dlPFC) during social reward processing, such that stronger FC was found at both very high and very low levels of adversity. Moreover, exposure to adversity predicted stronger FC between the amygdala and regions involved in salience detection, social cognition, and emotional memory (e.g., sgACC, precuneus, lingual gyrus, parahippocampal gyrus) during social threat processing. Analyses also revealed some evidence for blunted FC (VS-PCC for reward; amygdala-parahippocampal gyrus for threat) at very high and low levels of adversity. Overall, results suggest social experiences may play a critical role in shaping neural sensitivity to social feedback during adolescence. Future work will need to elucidate the implications of these patterns of neural function for the development of psychopathology.
