RESUMO

Exposure to early life adversity (ELA) is hypothesized to sensitize threat-responsive neural circuitry. This may lead individuals to overestimate threat in the face of ambiguity, a cognitive-behavioral phenotype linked to poor mental health. The tendency to process ambiguity as threatening may stem from difficulty distinguishing between ambiguous and threatening stimuli. However, it is unknown how exposure to ELA relates to neural representations of ambiguous and threatening stimuli, or how processing of ambiguity following ELA relates to psychosocial functioning. The current fMRI study examined multivariate representations of threatening and ambiguous social cues in 41 emerging adults (aged 18 to 19 years). Using representational similarity analysis, we assessed neural representations of ambiguous and threatening images within affective neural circuitry and tested whether similarity in these representations varied by ELA exposure. Greater exposure to ELA was associated with greater similarity in neural representations of ambiguous and threatening images. Moreover, individual differences in processing ambiguity related to global functioning, an association that varied as a function of ELA. By evidencing reduced neural differentiation between ambiguous and threatening cues in ELA-exposed emerging adults and linking behavioral responses to ambiguity to psychosocial wellbeing, these findings have important implications for future intervention work in at-risk, ELA-exposed populations.

RESUMO

Learning safe versus dangerous cues is crucial for survival. During development, parents can influence fear learning by buffering their children's stress response and increasing exploration of potentially aversive stimuli. Rodent findings suggest that these behavioral effects are mediated through parental presence modulation of the amygdala and medial prefrontal cortex (mPFC). Here, we investigated whether similar parental modulation of amygdala and mPFC during fear learning occurs in humans. Using a within-subjects design, behavioral (final N = 48, 6-17 years, mean = 11.61, SD = 2.84, 60% females/40% males) and neuroimaging data (final N = 39, 6-17 years, mean = 12.03, SD = 2.98, 59% females/41% males) were acquired during a classical fear conditioning task, which included a CS+ followed by an aversive noise (US; 75% reinforcement rate) and a CS-. Conditioning occurred once in physical contact with the participant's parent and once alone (order counterbalanced). Region of interest analyses examined the unconditioned stress response by BOLD activation to the US (vs. implicit baseline) and learning by activation to the CS+ (vs. CS-). Results showed that during US presentation, parental presence reduced the centromedial amygdala activity, suggesting buffering of the unconditioned stress response. In response to learned stimuli, parental presence reduced mPFC activity to the CS+ (relative to the CS-), although this result did not survive multiple comparisons' correction. These preliminary findings indicate that parents modulate amygdala and mPFC activity during exposure to unconditioned and conditioned fear stimuli, potentially providing insight into the neural mechanisms by which parents act as a social buffer during fear learning. RESEARCH HIGHLIGHTS: (1)This study used a within-participant experimental design to investigate how parental presence (vs. absence) affects youth's neural responses in a classical fear conditioning task. (2)Parental presence reduced the youth's centromedial amygdala activation to the unconditioned stimulus (US), suggesting parental buffering of the neural unconditioned response (UR). (3)Parental presence reduced the youth's mPFC activation to a conditioned threat cue (CS+) compared to a safety cue (CS-), suggesting possible parental modulation of fear learning.

RESUMO

Adolescence is a period of rapid biobehavioral change, characterized in part by increased neural maturation and sensitivity to one's environment. In this review, we aim to demonstrate that self-regulation skills are tuned by adolescents' social, cultural, and socioeconomic contexts. We discuss adjacent literatures that demonstrate the importance of experience-dependent learning for adolescent development: environmental contextual influences and training paradigms that aim to improve regulation skills. We first highlight changes in prominent limbic and cortical regions-like the amygdala and medial prefrontal cortex-as well as structural and functional connectivity between these areas that are associated with adolescents' regulation skills. Next, we consider how puberty, the hallmark developmental milestone in adolescence, helps instantiate these biobehavioral adaptations. We then survey the existing literature demonstrating the ways in which cultural, socioeconomic, and interpersonal contexts drive behavioral and neural adaptation for self-regulation. Finally, we highlight promising results from regulation training paradigms that suggest training may be especially efficacious for adolescent samples. In our conclusion, we highlight some exciting frontiers in human self-regulation research as well as recommendations for improving the methodological implementation of developmental neuroimaging studies and training paradigms.

RESUMO

Typologies serve to organize knowledge and advance theory for many scientific disciplines, including more recently in the social and behavioral sciences. To date, however, no typology exists to categorize an individual's use of emotion regulation strategies. This is surprising given that emotion regulation skills are used daily and that deficits in this area are robustly linked with mental health symptoms. Here, we attempted to identify and validate a working typology of emotion regulation across six samples (collectively comprised of 1,492 participants from multiple populations) by using a combination of computational techniques, psychometric models, and growth curve modeling. We uncovered evidence for three types of regulators: a type that infrequently uses emotion regulation strategies (Lo), a type that uses them frequently but indiscriminately (Hi), and a third type that selectively uses some (cognitive reappraisal and situation selection), but not other (expressive suppression), emotion regulation strategies frequently (Mix). Results showed that membership in the Hi and Mix types is associated with better mental health, with the Mix type being the most adaptive of the three. These differences were stable over time and across different samples. These results carry important implications for both our basic understanding of emotion regulation behavior and for informing future interventions aimed at improving mental health.

RESUMO

BACKGROUND: Prolonged stress exposure is associated with alterations in cortisol output. The COVID-19 pandemic represented a stressor for many, including children. However, a high-quality caregiving environment may protect against psychological problems and possibly against elevations in cortisol. We examined adolescents' physiological stress responses to the pandemic and the role of attachment in two longitudinal samples from the Netherlands and the United States (https://aspredicted.org/HHY_8MK). METHODS: Cortisol was assessed from hair samples before and during the pandemic, while attachment was self-reported prepandemic. Study 1 included a Dutch sample (N = 158; examined at ages 10 and later at 14 years old), whereas Study 2 included a US sample (N = 153; examined at ages 9-11 and again 2 years later) and an age-matched prepandemic sample (N = 29, 10-13 years old). Repeated-measures analyses of variance examined changes in cortisol from prepandemic to during the pandemic and the effect of attachment in each sample separately. RESULTS: After accounting for age, both studies revealed nonsignificant changes in hair cortisol and a nonsignificant effect of attachment. A significant effect of sex emerged in Study 1, with Dutch girls showing a significant cortisol increase during the pandemic, which was not explained by puberty. CONCLUSION: These findings suggest differential associations of the pandemic with hair cortisol increases by sex and country.

RESUMO

As social creatures, our relationships with other people have tremendous downstream impacts on health and well-being. However, we still know surprisingly little about how our social interactions regulate how we think and feel through life's challenges. Getting help from other people to change how one thinks about emotional events-known as "social reappraisal"-can be more effective in downregulating negative affect than reappraising on one's own, but it is unknown whether this regulatory boost from social support persists when people face the same events alone in the future. In a preregistered study of 120 young adults (N = 60 same-gender dyads, gender-split sample) involving in-lab emotion regulation tasks and a follow-up task online approximately 1 day later, we found that participants responded less negatively to aversive images that were socially regulated (i.e., reappraised with the help of a friend) both immediately and over time, as compared to images that had been solo regulated (i.e., reappraised on one's own) or not regulated (i.e., passively viewed). Interestingly, the regulatory boost from social support observed both in the lab and at follow-up was driven by women dyads. This work highlights one important mechanism explaining how support from others can facilitate emotional well-being: By changing peoples' lasting impressions of distressing events, interactions with others can help prepare them to cope with future exposure to those events on their own, underscoring how valuable others' perspectives can be when navigating ongoing emotional stressors.

RESUMO

The tendency to interpret ambiguous stimuli as threatening has been associated with a range of anxiety disorders. Responses to ambiguity may be particularly relevant to mental health during the transition from adolescence to adulthood ("emerging adulthood"), when individuals encounter unfamiliar challenges and navigate novel social situations. However, it remains unclear whether neural representations of ambiguity relate to risk for anxiety. The present study sought to examine whether multivariate representations of ambiguity - and their similarity to representations of threat - relate to appraisals of ambiguity or anxiety in a sample of emerging adults. Participants (N = 41) viewed threatening (angry), nonthreatening (happy), and ambiguous (surprised) facial stimuli while undergoing fMRI. Outside of the scanner, participants were presented with the same stimuli and categorized the ambiguous faces as positive or negative. Using representational similarity analyses (RSA), we investigated whether the degree of pattern similarity in responses to ambiguous, nonthreatening, and threatening faces within the amygdala related to appraisals of ambiguous stimuli and anxiety symptomatology. We found that individuals who evidenced greater similarity (i.e., less differentiation) in neural representations of ambiguous and nonthreatening faces within the left amygdala reported lower concurrent anxiety. Additionally, trial-level pattern similarity predicted subsequent appraisals of ambiguous stimuli. These findings provide insight into how neural representations of ambiguity relate to risk or resilience for the development of anxiety.

RESUMO

PURPOSE: Prior work suggests sexual minority (e.g., gay, bisexual) young adults are at greater risk for depression and anxiety. However, the majority of said work focuses exclusively on self-reported sexual minority identity and neglects same-gender attraction. The current study aimed to characterize links between identity- and attraction-based indicators of sexual minority status and depression and anxiety in young adults, and to examine the ongoing significance of caregiver support in mental health during this key developmental period. METHODS: 386 youth (mean age = 19.92 years; SD = 1.39) reported their sexual orientation identity and experiences of attraction toward men and/or women. Participants also reported on anxiety, depression, and caregiver social support. RESULTS: While less than 16% of participants identified as sexual minority individuals, nearly half reported same-gender attraction. Self-identified sexual minority participants reported significantly higher depression and anxiety than self-identified heterosexual participants. Similarly, same-gender attracted individuals exhibited heightened depression and anxiety compared to exclusively different-gender attracted individuals. Greater caregiver social support predicted lower depression and anxiety. DISCUSSION: The present findings suggest that not only are self-identified sexual minority individuals at heightened risk for depression and anxiety symptoms, but also that this risk extends to a larger group of young people who experience same-gender attraction. These results demonstrate that better mental health supports may be needed for youth who identify as sexual minority individuals or report same-gender attraction. That higher caregiver social support was associated with lower mental illness risk suggests caregivers may be key to mental health promotion during young adulthood.

RESUMO

Emotion regulation (ER) strategies and beliefs about emotions (implicit theories of emotions; ITE) may shape psychosocial outcomes during turbulent times, including the transition to adulthood and college while encountering stressors. The normative stressors associated with these transitions were compounded by the COVID-19 pandemic, providing a novel opportunity to examine how emerging adults (EAs) cope with sustained stressors. Stress exposures can heighten existing individual differences and serve as "turning points" that predict psychosocial trajectories. This pre-registered study (https://osf.io/k8mes) of 101 EAs (18-19 years old) examined whether ITE (believing emotions can change or not; incremental vs. entity beliefs) and ER strategy usage (cognitive reappraisal and expressive suppression usage) predicted changes in anxiety symptomatology and feelings of loneliness across five longitudinal assessments (across a 6-month period) before and during the initial months of the COVID-19 pandemic. On average, EAs' anxiety decreased after the pandemic outbreak but returned to baseline over time, while loneliness remained relatively unchanged across time. ITE explained variance in anxiety across time over and above reappraisal use. Conversely, reappraisal use explained variance in loneliness over and above ITE. For both anxiety and loneliness, suppression use resulted in maladaptive psychosocial outcomes across time. Thus, interventions that target ER strategies and ITE may ameliorate risk and promote resilience in EAs who experience increased instability.

RESUMO

Emotion regulation is particularly important for adolescents as they undergo normative developmental changes in affective systems and experience heightened risk for psychopathology. Despite a high need for emotion regulation during adolescence, commonly studied emotion regulation strategies like cognitive reappraisal are less beneficial for adolescents than adults because they rely on neural regions that are still developing during this period (i.e., lateral prefrontal cortex). However, adolescence is also marked by increased valuation of peer relationships and sensitivity to social information and cues. In the present review, we synthesize research examining emotion regulation and peer influence across development to suggest that sensitivity to peers during adolescence could be leveraged to improve emotion regulation for this population. We first discuss developmental trends related to emotion regulation at the level of behavior and brain in adolescents, using cognitive reappraisal as an exemplar emotion regulation strategy. Next, we discuss social influences on adolescent brain development, describing caregiver influence and increasing susceptibility to peer influence, to describe how adolescent sensitivity to social inputs represents both a window of vulnerability and opportunity. Finally, we conclude by describing the promise of social (i.e., peer-based) interventions for enhancing emotion regulation in adolescence.

RESUMO

Social decision-making is omnipresent in everyday life, carrying the potential for both positive and negative consequences for the decision-maker and those closest to them. While evidence suggests that decision-makers use value-based heuristics to guide choice behavior, very little is known about how decision-makers' representations of other agents influence social choice behavior. We used multivariate pattern expression analyses on fMRI data to understand how value-based processes shape neural representations of those affected by one's social decisions and whether value-based encoding is associated with social decision preferences. We found that stronger value-based encoding of a given close other (e.g. parent) relative to a second close other (e.g. friend) was associated with a greater propensity to favor the former during subsequent social decision-making. These results are the first to our knowledge to explicitly show that value-based processes affect decision behavior via representations of close others.

RESUMO

BACKGROUND: The interval between adolescence and adulthood, 'emerging adulthood' (EA), lays the foundation for lifelong health and well-being. To date, there exist little empirical data - particularly in the neurobiological domain - to establish markers of risk and resilience during the transition to adulthood. This gap in the literature is concerning given the numerous forms of psychiatric illness that emerge or worsen during this period. METHODS: In this review, we focus on two strands of research with distinct importance for EA: reward sensitivity, and tolerance of ambiguity. We begin by placing these domains in a framework that considers the unique developmental goals of EA and then synthesize emerging neurobiological research on how these domains develop during EA. We then consider their role in common mental health problems that occur during this interval as well as how social support may moderate outcomes. Finally, we offer recommendations for advancing research to understand developmental process and outcomes in EA. FINDINGS AND CONCLUSIONS: Few longitudinal studies specifically address emerging adult development and the milestones that characterize this interval. Data on neurobiological development are similarly sparse. Understanding neurobiological development during this window and its links to key adjustment outcomes is crucial for optimizing outcomes.

RESUMO

Early caregiving adversity (ECA) is associated with elevated psychological symptomatology. While neurobehavioral ECA research has focused on socioemotional and cognitive development, ECA may also increase risk for "low-level" sensory processing challenges. However, no prior work has compared how diverse ECA exposures differentially relate to sensory processing, or, critically, how this might influence psychological outcomes. We examined sensory processing challenges in 183 8-17-year-old youth with and without histories of institutional (orphanage) or foster caregiving, with a particular focus on sensory over-responsivity (SOR), a pattern of intensified responses to sensory stimuli that may negatively impact mental health. We further tested whether sensory processing challenges are linked to elevated internalizing and externalizing symptoms common in ECA-exposed youth. Relative to nonadopted comparison youth, both groups of ECA-exposed youth had elevated sensory processing challenges, including SOR, and also had heightened internalizing and externalizing symptoms. Additionally, we found significant indirect effects of ECA on internalizing and externalizing symptoms through both general sensory processing challenges and SOR, covarying for age and sex assigned at birth. These findings suggest multiple forms of ECA confer risk for sensory processing challenges that may contribute to mental health outcomes, and motivate continuing examination of these symptoms, with possible long-term implications for screening and treatment following ECA.

RESUMO

Early life stress (ELS) is common in the United States and worldwide, and contributes to the development of psychopathology in individuals with these experiences and their offspring. A growing body of research suggests that early life stress may contribute to adverse health partly through modulation of immune (and particularly inflammatory) responses. Therefore, increased maternal prenatal inflammation has been proposed as a mechanistic pathway by which the observed cross-generational effects of parental early life stress on child neuropsychiatric outcomes may be exerted. We examined associations between early life stress and molecular markers of inflammation (specifically pro-inflammatory gene expression and receptor-mediated transcription factor activity) and a commonly studied circulating marker of inflammation (C-Reactive Protein) in a diverse group of women in or near their third trimester of pregnancy, covarying for age, race/ethnicity, BMI, concurrent infection, concurrent perceived stress, and per capita household income. Mothers who experienced higher levels of early life stress had significantly increased pro-inflammatory (NF-κB) and decreased anti-viral (IRF) transcription factor activity. Transcripts that were up or down regulated in mothers with high ELS were preferentially derived from both CD16+ and CD16- monocytes. Early life stress was not associated with elevated CRP. Taken together, these findings provide preliminary evidence for an association between ELS and a pro-inflammatory transcriptional phenotype during pregnancy that may serve as a mechanistic pathway for cross-generational transmission of the effects of early life stress on mental and physical health.

RESUMO

Although considerable research has demonstrated the importance of social relationships for well-being, limited work has assessed how people help regulate each other's emotions, a process called social emotion regulation. The present research utilized two experiments in 2020 (N1 = 50, N2 = 268) where people shared and responded to personal experiences to examine: (a) the kinds of regulatory support people offered others; (b) how people felt receiving different types of social feedback about their experiences; and (c) whether the support they offered others shaped how they felt receiving different feedback. When providing feedback to a confederate, participants varied in whether they chose to use validation, which affirms someone's feelings, or one of three types of social reappraisals, which help others change how they think about an emotional experience (i.e., temporal distancing: emphasizing how things change over time; positive focus: focusing on the bright side; and perspective taking: considering others' perspectives). Across studies, when participants received feedback about their own experiences, validation was the most comforting and preferred feedback. In Study 2, temporal distancing emerged as the most comforting, helpful, and preferrable type of social reappraisal and was the only reappraisal perceived as no less helpful than validation. Additionally, participants who provided social reappraisal to the confederate benefited most from receiving this type of support from others. Together, these results highlight the variability in how people use social emotion regulation strategies to support others and demonstrate how such differences in implementation, as well as individual differences in those receiving support, can shape social regulatory outcomes.

RESUMO

Therapeutic dance has been increasingly used as a treatment modality for sexual trauma, yet its evidence-based efficacy has not yet been catalogued. We therefore conducted a systematic review to summarize the existing evidence for therapeutic dance as an intervention for healing after sexual trauma. We searched 5 major databases to identify intervention studies on the use of therapeutic dance for individuals with histories of sexual trauma. Studies were included based on the following criteria: 1) the study involves individuals who have been exposed to sexual trauma; 2) the study reports on any form of dance as a therapeutic intervention; and 3) the study reports on dance intervention outcomes. A total of 1,686 sources were identified. Of these, 11 articles met eligibility criteria and were assessed. Reported outcomes were extracted and organized into emergent domains. We found that therapeutic dance acts upon three broad domains-affect, self, and interpersonal relationships - and can be delivered in diverse settings. Across the studies, dance showed benefits on outcomes. However, a significant weakness of the current peer-reviewed literature is the lack of robust empirical intervention research on dance therapy. Overall, the emerging literature suggests that therapeutic dance is a potential intervention for those who have experienced sexual trauma. The review findings presented here can be used to inform practitioners and systems of care targeted for those who have been subject to sexual trauma.

RESUMO

Beginning college involves changes that can increase one's vulnerability to loneliness and associated negative outcomes. Parent and friend relationships are potential protective factors against loneliness given their positive association with adjustment. The present longitudinal study, with data collection at baseline, 1 month, and 2 months later, assessed the comparative effects of self-reported parent and friend relationship quality on loneliness in first-year college students (N = 101; 80 female, Mage = 18.36). At baseline, parent and friend relationship quality were negatively associated with loneliness. Longitudinal data revealed that friend relationship quality interacted with time, such that its effects on loneliness attenuated over the course of 2 months. By contrast, parent relationship quality continued to predict lower loneliness 2 months post-baseline. These results highlight the importance of close relationships and suggest that targeting relationship quality could be effective in helping youth transition to college.

RESUMO

Cognitive systems that track, update, and utilize information about reward (consequences) and risk (uncertainty) are critical for adaptive decision-making as well as everyday functioning and well-being. However, it remains unclear how individual differences in reward and risk sensitivity are independently shaped by environmental influences and give rise to decision-making. Here, we investigated the impact of early life experience-a potent sculptor of development-on behavioral sensitivity to reward and risk. We administered a widely used decision-making paradigm to 55 adolescents and young adults who were exposed to early deprivation in the form of early institutional (orphanage) care (a type of early life adversity) and 81 comparison individuals who were reared by their biological parents and did not experience institutional care. Leveraging random coefficient regression and computational models, we observed that previously institutionalized individuals displayed general reward hyposensitivity, contributing to a decreased propensity to make decisions that stood to earn relatively large rewards relative to comparison individuals. By contrast, group differences in risk sensitivity were selectively observed on loss, but not gain, trials. These results are the first to independently and explicitly link early experiences to reward and risk sensitivity during decision-making. As such, they lay the groundwork for therapeutic efforts to identify and treat adversity-exposed individuals at risk for psychiatric disorders characterized by aberrant decision-making processes.

RESUMO

Adults quickly orient toward sources of danger and deploy fight-or-flight tactics to manage threatening situations. In contrast, infants who cannot implement the safety strategies available to adults and depend heavily on caregivers for survival are more likely to turn toward familiar adults, such as their parents, to help them navigate threatening circumstances. However, work has yet to investigate how readily children and adolescents orient toward their parents in threatening or fearful contexts. The current work addressed this question using a visual search paradigm that included arrays of parents' and strangers' faces as target and distractor stimuli, preceded by a fear or neutral emotional priming procedure. Linear mixed-effects models showed that children and adolescents (N = 88, age range = 4-17 years; 42M/46F) were faster to search for the face of their parent than of a stranger. However, fear priming attenuated this effect of the parent on search times, such that children and adolescents were significantly slower to orient toward their parent in an array of strangers' faces if they were first primed with fear as opposed to a neutral video. This work indicates that fear priming may phasically interfere with parental orienting during childhood and adolescence, possibly because fear reallocates attention away from parents and toward (potentially threatening) unfamiliar people in the environment to facilitate the development of independent threat learning and coping systems.

RESUMO

Despite its transdiagnostic significance, there is modest evidence with respect to the predictive validity of childhood irritability, especially across developmental periods; similarly, little is known about explanatory factors underlying these predictions. This study had two goals: (1) to test the predictive validity of childhood irritability with respect to adolescent internalizing and externalizing problems, controlling for baseline ADHD and related psychopathology and (2) to test theoretically-derived family (i.e., parenting behavior, parenting stress) and social (i.e., peer status, social skills) constructs as explanatory factors of adolescent psychopathology. Two hundred thirty ethnically diverse (51.5% White) 5-10-year-old youth (32% female) with (n = 121) and without (n = 110) ADHD completed three separate laboratory-based assessments across six to seven years. Temporally-ordered predictors, putative mediators, and psychopathology outcomes were assessed using multiple informants (i.e., parent, teacher, youth) and methods (i.e., structured interviews, normed rating scales). Controlling for demographic factors, clinical correlates, and baseline psychopathology, childhood irritability uniquely predicted adolescent externalizing problems, but not internalizing problems. Next, analyses revealed that low social skills partially explained predictions of adolescent internalizing problems. However, family or social factors did not underlie predictions of adolescent externalizing problems. These preliminary findings support the predictive validity of childhood irritability with respect to early adolescent externalizing problems and implicate low social skills as a potentially unique mediator of internalizing outcomes. Intervention-induced improvements in social skills may minimize emergent psychopathology initiated by significant childhood irritability.
