Item Social versus non-social behavioral inhibition: Differential prediction from early childhood of long-term psychosocial outcomes(Wiley, 2023-06-22) Tan, Enda; Zeytinoglu, Selin; Morales, Santiago; Buzzell, George A.; Almas, Alisa N.; Degnan, Kathryn A.; Chronis-Tuscano, Andrea; Henderson, Heather; Pine, Daniel S.; Fox, Nathan A.Behavioral inhibition (BI) is a temperamental style characterized by cautious and fearful behaviors in novel situations. The present multi-method, longitudinal study examined whether young children's observed and parent-reported BI in social versus non-social contexts predicts different long-term psychosocial outcomes. Participants (N = 279) were drawn from a longitudinal study of socioemotional development. BI in social contexts (“social BI”) was measured via children's observed wariness toward unfamiliar adults and peers at 24 and 36 months and parents’ reports of children's social fear/shyness at 24, 36, and 48 months. BI in non-social contexts (“non-social BI”) was measured via children's observed fearful responses to masks and novel toys, and parents’ reports of children's distress to non-social novelty at 9 months and non-social fear at 48 months. At 15 years, anxiety was assessed via adolescent- and parent-reports, and global internalizing and externalizing problems were assessed via parent-reports. Confirmatory factor analysis showed that a two-factor model fit the BI data significantly better than a single-factor model, providing evidence for the dissociation of BI in social versus non-social contexts. Social BI was uniquely associated with adolescent social anxiety, whereas non-social BI was specifically associated with adolescent separation anxiety. Neither social BI nor non-social BI predicted global internalizing and externalizing problems, providing evidence for the specific relations between BI and anxiety problems. Together, these results suggest that young children's inhibited responses in social versus non-social situations predict different subtypes of anxiety problems in adolescence, highlighting the multifaceted nature of BI and the divergent trajectories of different anxiety problems.Item DEVELOPMENTAL AND INDIVIDUAL DIFFERENCES IN REWARD PROCESSING ACROSS CHILDHOOD AND ADOLESCENCE(2010) Kirwan, Michael Louis; Fox, Nathan A; Human Development; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)Adolescence is a developmental period characterized by maturation across multiple domains. This maturation is not without difficulties, however, as adolescents also display increased negative mood, conflict with parents, and risk-taking behaviors. Increased risk-taking is thought to be the byproduct of changes in reward circuits in the brain, and while a solid foundation of research has provided evidence for changes in reward processing during adolescence compared to adulthood, little is known about the changes that occur from childhood into adolescence. The current study addresses this gap in the literature with an investigation of changes in behavioral performance on a reward-processing task using a cross-sectional sample of children and adolescents. Three primary findings emerged from this study. First, adolescents displayed faster reaction times than 8-year-olds. Second, subjects responded faster and more accurately on trials with greater potential rewards. Finally, individual differences were related to reward sensitivity, reaction times, and response accuracies.Item School-Related Apathy in 8th- and 10th- Grade Students: A Mixed-Method Exploration of Definitions, Construct Independence, Correlates, and Grade-Level Differences(2007-04-26) Riconscente, Michelle Maria; Alexander, Patricia A; Human Development; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)Research-based and folk conceptualizations of school-related apathy were explored in 309 8th- and 10th- grade Catholic school students and their teachers. Definitions, construct independence, and relation to select individual and group differences including grade level were examined. Findings indicated that while some independence exists among the set of five constructs assessed--adolescent apathy, amotivation, apathy syndrome, disengagement, and work avoidance--substantial overlap is present that can inform development of a more parsimonious conceptualization of students' lack of school motivation centered on perceived relevance and a general attitude of interest. Results also demonstrated only moderate levels of agreement between research-based and teacher identification of students low on school-related motivation; however, both approaches indicate that approximately 1 in 4 students manifests markedly low school-related motivation. Relations of several individual and group differences to conceptualizations of school-related apathy were documented in expected directions. Implications of the findings for educational research and practice are discussed.
