This study tested the pathways supporting adolescent development of prosocial and rebellious behavior. Self-report and structural brain development data were obtained in a three-wave, longitudinal neuroimaging study (8–29 years, N = 210 at Wave 3). First, prosocial and rebellious behavior assessed at Wave 3 were positively correlated. Perspective taking and intention to comfort uniquely predicted prosocial behavior, whereas fun seeking (current levels and longitudinal changes) predicted both prosocial and rebellious behaviors. These changes were accompanied by developmental declines in nucleus accumbens and medial prefrontal cortex (MPFC) volumes, but only faster decline of MPFC (faster maturity) related to less rebellious behavior. These findings point toward a possible differential susceptibility marker, fun seeking, as a predictor of both prosocial and rebellious developmental outcomes.  相似文献

Globalization prompts remote acculturation toward U.S. culture in Jamaica; this study used a bioecological systems approach to examine its proximal impact on nutrition through U.S. cable TV consumption, and maternal influences in the home. Overall, 330 randomly selected adolescent–mother dyads from schools in Kingston, Jamaica (Madolescent_age = 13.8 years, SDadolescent_age = 1.8) completed questionnaires reporting American identity and behavioral preferences, daily time spent watching U.S.‐produced TV programs, and frequency of eating unhealthy foods. Actor–partner interdependence models revealed that girls’ American identity/behavior directly predicted their unhealthy eating, whereas girls’ mothers and boys’ American identity/behavior indirectly predicted unhealthy eating as mediated by their U.S. TV hours. Additionally, mothers’ American identity/behavior predicted daughters’ unhealthy eating as mediated by mothers’ U.S. TV hours. Remote acculturation theory may facilitate more targeted research and prevention/intervention.  相似文献

This study examined correspondence between timing (onset) and tempo (rate) of sexual maturation prospectively (average ages 11–16 years) measured by gonadal hormones and secondary sex characteristics (Tanner stage) using dual-process models, and associations of these measures with substance use (SU) involvement in boys at age 16 years (N = 534, 77.5% White/22.5% Non-White). All measures of timing were highly associated. Early Tanner stage timing often predicted slower increases in gonadal steroids, but not the reverse; patterns varied by ethnicity. Hormone and Tanner stage measures were similar earlier in development but diverged later in development. In White boys only, early timing of the pubertal rise in testosterone was associated with increased SU involvement, suggesting a physiological rather than psychosocial mechanism of association.  相似文献

Delay discounting is a stable trait measure of impulsivity. Engaging in episodic future thinking (EFT) can reduce discounting, but whether individual differences in discounting are associated with differences in future thinking remains unclear. Here, this association was tested in healthy adolescents (n = 49, age range = 12–16 years, fluent German speakers, from a large German city). Data collection was between December 2011 and December 2012. Vividness of EFT (assessed via the Autobiographical Memory Interview) was negatively correlated with discounting (r = ?.41, 95% CI [?.63, ?.13], r2 = .17). Regression analyses confirmed that this association was stable when controlling for additional variables, including hormonal measures of pubertal maturation and intelligence. EFT may attenuate impulsivity in young people at risk of engaging in problematic behavior.  相似文献

Stress responses to social evaluation are thought to increase during adolescence, which may be due to pubertal maturation. However, empirical evidence is scarce. This study is the first to investigate the relation between pubertal development and biological responses to a social‐evaluative stressor longitudinally. Participants performed the Leiden Public Speaking Task twice, with a 2‐year interval (N = 217; age at Time 1: 8–17 years). The results support an increase in sensitivity to social evaluation during adolescence. The overall cortisol and alpha‐amylase responses increased—both between and within participants—and were more strongly related to self‐reported pubertal development than to age. The cortisol response shifted from speech delivery toward anticipation. The alpha‐amylase response increased in both phases.  相似文献

This study examined longitudinal effects of adolescent and parent cultural stress on adolescent and parent emotional well-being and health behaviors via trajectories of adolescent and parent family functioning. Recent immigrant Latino adolescents (Mage = 14.51) and parents (Mage = 41.09; N = 302) completed measures of these constructs. Latent growth modeling indicated that adolescent and parent family functioning remained stable over time. Early levels of family functioning predicted adolescent and parent outcomes. Baseline adolescent cultural stress predicted lower positive adolescent and parent family functioning. Latent class growth analyses produced a two-class solution for family functioning. Adolescents and parents in the low family functioning class reported low family functioning over time. Adolescents and parents in the high family functioning class experienced increases in family functioning.  相似文献

This multimethod multisample longitudinal study examined how neurological substrates associated with goal directedness and information seeking are related to adolescents’ identity. Self‐reported data on goal‐directedness were collected across three biannual waves in Study 1. Identity was measured one wave later. Study 1 design and measurements were repeated in Study 2 and extended with structural brain data (nucleus accumbens [NAcc] and prefrontal cortex gray matter volume [PFC]), collected across three biannual waves. Study 1 included 497 adolescents (Mage T1 = 13.03 years) and Study 2 included 131 adolescents (Mage T1 = 14.69 years). Using latent growth curve models, goal directedness, NAcc, and PFC volume predicted a stronger identity one wave later. These findings provide crucial new insights in the underlying neurobiological architecture of identity.  相似文献

Frontal asymmetry (FA), the difference in brain activity between the left versus right frontal areas, is thought to reflect approach versus avoidance motivation. This study (2012–2021) used functional near-infrared spectroscopy to investigate if infant (Mage = 7.63 months; N = 90; n = 48 male; n = 75 White) FA in the dorsolateral prefrontal cortex relates to psychopathology in later childhood (Mage = 62.05 months). Greater right FA to happy faces was associated with increased internalizing (η2 = .09) and externalizing (η2 = .06) problems at age 5 years. Greater right FA to both happy and fearful faces was associated with an increased likelihood of a lifetime anxiety diagnosis (R2 > .13). FA may be an informative and early-emerging marker for psychopathology.  相似文献

To study the contribution of perceived parent achievement goals to students' attitudes towards academic help seeking, 4th, 6th, 7th, and 9th grade students in Greece (n = 712) reported perceptions of their parents' achievement goals, personal achievement goal orientations, and help-seeking beliefs and intentions. Students' mastery goal orientation positively predicted their help-seeking attitudes (perceived benefits and intentions to seek help) and negatively predicted their help-seeking avoidance attitudes (perceived costs and intentions to avoid seeking help), whereas performance-avoidance orientation directly predicted their help-seeking avoidance attitudes. Multiple-group path analysis indicated that perceived parent goals predicted student help seeking and help avoidance attitudes through students' own achievement goal orientations. Further, the pattern of relations varied by grade level. Results are discussed in light of current theory and research on the developmental phases of parental influence on student motivation and self-regulated learning.  相似文献

This exploratory study examined the relation between pubertal timing and dimensions of ethnic-racial identity among adopted Korean Americans raised transracially in White families. The study also examined whether internalized racism moderated the association between pubertal timing and ethnic-racial identity. Adopted Korean American adolescents (N = 202; 108 females; ages 13–19 years) completed measures of pubertal development, ethnic-racial identity, and internalized racism in 2007. There was no significant main effect of pubertal timing for either male or female adolescents. Internalized racism moderated the relation between pubertal timing and ethnic-racial identity clarity (B = −.16, p = .015) among male adolescents. Specifically, earlier pubertal timing was significantly associated with lower ethnic-racial identity clarity for male adolescents with higher levels of internalized racism.  相似文献

Personality and identity formation are intricately linked in adolescent development. The personality disposition of perfectionism has been associated with identity processes, but their longitudinal interplay in adolescence has not yet been investigated. This four-wave study, with 5- to 6-month intervals between each wave (N = 744 Caucasian adolescents, Mage = 15.2 years, 55% girls), examined associations between perfectionism (self-oriented and socially prescribed) and identity processes in the domain of future plans. Self-oriented perfectionism predicted increases in commitment making, identification with commitment, and exploration in depth. Socially prescribed perfectionism showed bidirectional positive relations with ruminative exploration. Exploration in depth predicted increases in socially prescribed perfectionism. Findings suggest that perfectionism is an important personality disposition in adolescent identity formation unfolding over time.  相似文献

This study investigated whether temperamental approach–withdrawal underlies infants' responses to novel foods. Data were drawn from a longitudinal study of mother–infant dyads (n = 136). Approach–withdrawal responses to novel foods and novel toys were coded when infants were 6 and 12 months of age. When infants were 18 months of age, approach–withdrawal behaviors, positive affect, and negative affect were used in a latent profile analysis to identify groups of toddlers who exhibited similar responses to novelty. As predicted, novel food and novel toy responses were concurrently associated at 12 months and followed a similar developmental pattern across the 1st year. Furthermore, novel food acceptance at 12 months of age, but not 6 months, predicted greater toddler approach.  相似文献

This study examined longitudinal acculturation patterns, and their associations with family functioning and adolescent risk behaviors, in Hispanic immigrant families. A sample of 266 Hispanic adolescents (Mage = 13.4) and their primary parents completed measures of acculturation, family functioning, and adolescent conduct problems, substance use, and sexual behavior at five timepoints. Mixture models yielded three trajectory classes apiece for adolescent and parent acculturation. Assimilated adolescents reported the poorest family functioning, but adolescent assimilation negatively predicted adolescent cigarette smoking, sexual activity, and unprotected sex indirectly through family functioning. Follow‐up analyses indicated that discrepancies between adolescent and parent family functioning reports predicted these adolescent outcomes. Results are discussed regarding acculturation trajectories, adolescent risk behavior, and the mediating role of family functioning.  相似文献

Positive peer and romantic relationships are crucial for adolescents' positive adjustment and relationships with parents lay the foundation for these relationships. This longitudinal meta-analysis examined how parent–adolescent relationships continue into later peer and romantic relationships. Included longitudinal studies (k = 54 involving peer relationships, k = 38 involving romantic relationships) contained demographically diverse samples from predominantly Western cultural contexts. Multilevel meta-regressions indicated that supportive and negative parent–adolescent relationships were associated with supportive and negative future peer and romantic relationships. Meta-analytic structural equation modeling (k = 54) indicated that supportive parent–adolescent relationships unidirectionally predicted supportive and negative peer relationships, while negative parent–adolescent relationships were bidirectionally associated with supportive and negative peer relationships. Maintaining mutually supportive relationships with parents may help adolescents to develop positive social relationships.  相似文献

This study tested whether the strength of the mediational pathway involving interparental conflict, adolescent emotional insecurity, and their psychological problems depended on the quality of their sibling relationships. Using a multimethod approach, 236 adolescents (Mage = 12.6 years) and their parents participated in three annual measurement occasions. Tests of moderated mediation revealed that indirect paths among interparental conflict, insecurity, and psychological problems were significant for teens with low, but not high, quality bonds with siblings. High-quality (i.e., strong) sibling relationships conferred protection by neutralizing interparental conflict as a precursor of increases in adolescent insecurity. Results did not vary as a function of the valence of sibling relationship properties, adolescent sex, or gender and age compositions of the dyad.  相似文献

Self-conscious emotions arise from evaluating the self through the eyes of others. Given that children with autistic traits may experience difficulties with understanding others' minds, they might show less attuned self-conscious emotions. Two-to-five-year-old children's (N = 98, Mage = 48.54 months, 50% girls, 92% White) self-conscious emotions (guilt, embarrassment, and shame-like avoidance) were observed after children “broke” the experimenter's favorite toy. Data were collected from March 2018 till June 2019. Children with more autistic traits showed less theory of mind (ToM), and more shame-like avoidance, but associations were not mediated by ToM. This provides initial evidence that children with more autistic traits may show disturbances in some but not all self-conscious emotions, which could hinder their social functioning.  相似文献

Parental discriminatory experiences can have significant implications for adolescent adjustment. This study examined family processes linking parental perceived discrimination to adolescent depressive symptoms and delinquent behaviors by using the family stress model and incorporating family systems theory. Participants were 444 Chinese American adolescents (Mage.wave1 = 13.03) and their parents residing in Northern California. Testing of actor–partner interdependent models showed a significant indirect effect from earlier paternal (but not maternal) perceived discrimination to later adolescent adjustment through paternal depressive symptoms and maternal hostility toward adolescents. The results highlight the importance of including both parents and examining actor and partner effects to provide a more comprehensive understanding of how maternal and paternal perceived discrimination differentially and indirectly relate to adolescent adjustment.  相似文献

This study tested whether maternal responsiveness moderated or mediated pathways from iron deficiency (ID) at 12–18 months to adolescent behavior problems. Participants were part of a large Chilean cohort (N = 933). Iron status was assessed at 12 and 18 months. Maternal responsiveness was assessed at 9 months and 5 years. Parents reported their child’s symptomology at 5 years, 10 years, and adolescence (11–17 years; M = 14.4). Structural equation modeling identified a previously unrecognized pathway by which child externalizing problems and negative maternal responsiveness at 5 years mediated associations between ID at 12–18 months and adolescent internalizing, externalizing, and social problems. Positive maternal responsiveness in infancy did not buffer those with ID anemia from developing 5-year internalizing problems.  相似文献

Adolescence is an important time for social development during which friendships become more intimate and complex. In this functional magnetic resonance imaging (fMRI) study we tested how outcomes for friends are processed on the neural level across adolescence. Participants between 8 and 27 years of age were tested twice with a 2‐year difference between the first (N = 299) and second (N = 254) time points. Participants performed a task in which they could win and lose money for themselves and their best friend. Mixed linear models revealed a linear decrease in activity in social brain regions for friend > self over development. These results confirm changes in the social brain network across adolescent development, we further show that individual differences are related to these neural changes.  相似文献

We initiated and structured a single program that supervised teachers, some with neuroscience or psychology degrees, to collaborate and explore the effects of science of learning‐translated pedagogy. This article reports on the 34 findings from teacher‐led randomized controlled trials (RCTs) and replications. Teachers designed trials, looking at areas such as attention, memory, and spaced learning. Overall, positive effects were found over short periods (1–6 weeks; r = 0.15, p < .0001 [d = 0.30], N = 2,157). However, retrieval practice (testing as a learning experience) had differential effects mediated by age, approach, and lesson content. Results suggest science of learning‐translated pedagogy needs extensive replication to establish how best to use laboratory evidence in classrooms. Multiple planned replication of teacher‐led RCTs has potential as an evaluation tool, combining high levels of mundane realism with strong internal validity and the potential to build cost effective large samples for meta‐analysis.  相似文献
