Although these problems have been well described, the related adolescent behaviors of risk-taking and sensation-seeking have not yet been explored in this population. This study examined risk-taking and sensation-seeking propensity, and associations with conduct problems and depressive symptoms, in early adolescents who were adopted as young children from institutional care. Methods Risk-taking and sensation-seeking propensities of 12- and 13-year-old postinstitutionalized (PI; n = 54) adolescents were compared with two groups: youth who were internationally adopted early from foster care (PFC; n = 44) and nonadopted youth (NA; n = 58). Participants were recruited to equally represent pre/early- and mid/late-pubertal stages within each group. Participants completed the youth version of the Balloon Analogue Risk Task (Lejuez et al., ) and the Sensation-Seeking Scale for Children (Russo et al., ). Parents completed clinical ratings of participants' conduct problems and depressive symptoms.

Failure is Not an Option: Risk-Taking is Moderated by Anxiety and Also by Cognitive Ability in Children and Adolescents Diagnosed with an Autism Spectrum Disorder / Mikle SOUTH in Journal of Autism and Developmental Disorders, 41-1 (January 2011)

In 40 children and adolescents diagnosed with ASD and 37 IQ—and age-matched comparison participants (the TYP group), we found no differences in summary measures on an experimental risk-taking task. However, anxiety and IQ predicted risk-taking only in the ASD group. Risk-taking was correlated with behavioral inhibition in the ASD group and behavioral activation in the TYP group. We suggest that performance on the task was motivated by fear of failure in the ASD group and by sensitivity to reward in the TYP group. Behavioral markers of anxiety and cognitive ability may improve conceptualization of heterogeneity in ASD.

The preference for surprise in reinforcement learning underlies the differences in developmental changes in risk preference between autistic and neurotypical youth / Kentaro KATAHIRA ; Hironori AKECHI ; Atsushi SENJU in Molecular Autism, 16 (2025)  

Public ISBD [article]  inMolecular Autism > 16 (2025) . - 3 Titre : The preference for surprise in reinforcement learning underlies the differences in developmental changes in risk preference between autistic and neurotypical youth Type de document : Texte imprimé et/ou numérique Auteurs : Kentaro KATAHIRA, Auteur ; Hironori AKECHI, Auteur ; Atsushi SENJU, Auteur Article en page(s) : 3 Langues : Anglais (eng) Mots-clés : Humans  Adolescent  Child  Male  Female  Reinforcement, Psychology  Young Adult  Autistic Disorder/psychology  Adult  Choice Behavior  Risk-Taking  Learning  Autism  Developmental changes  Reinforcement learning  Risk preference  Surprise  the Declaration of Helsinki and was approved by the Committee on Ethics of  Experimental Research on Human Subjects, Graduate School of Arts and Sciences,  University of Tokyo (156-17). Consent for publication: Not applicable. Competing  interests: The authors declare no competing interests. Index. décimale : PER Périodiques Résumé : BACKGROUND: Risk preference changes nonlinearly across development. Although extensive developmental research on the neurotypical (NTP) population has shown that risk preference is highest during adolescence, developmental changes in risk preference in autistic (AUT) people, who tend to prefer predictable behaviors, have not been investigated. Here, we aimed to investigate these changes and underlying computational mechanisms. METHOD: We ran a game-like risk-sensitive reinforcement learning task on 75 participants aged 6-30 years (AUT group, n = 31; NTP group, n = 44). Focusing on choices between alternatives with the same objective value but different risks, we calculated the risk preference and stay probability of a risky choice after a rewarding or non-rewarding outcome. Analyses using t-tests and multiple regression analyses were conducted. Using the choice-related data of each participant, we fit four reinforcement learning models and compared the fit of each model to the data. Furthermore, we validated the results of model fitting with multiple methods, model recovery, parameter recovery, and posterior predictive check. RESULTS: We found a significant difference in nonlinear developmental changes in risk preference between the AUT and NTP groups. The computational modeling approach with reinforcement learning models revealed that individual preferences for surprise modulated such preferences. CONCLUSIONS: These findings indicate that for NTP people, adolescence is a developmental period involving risk preference, possibly due to lower surprise aversion. Conversely, for AUT people, who show opposite developmental change of risk preference, adolescence could be a developmental period involving risk avoidance because of low surprise preference.

Longitudinal associations between specific types of emotional reactivity and psychological, physical health, and school adjustment / Jessica M. DOLLAR in Development and Psychopathology, 35-2 (May 2023)

KEANE, Auteur ; Lenka SHRIVER, Auteur ; Laurie WIDEMAN, Auteur Article en page(s) : p.509-523 Langues : Anglais (eng) Mots-clés : emotional reactivity  physical health  psychopathology  risk-taking  school problems Index. décimale : PER Périodiques Résumé : Using a multimethod, multiinformant longitudinal design, we examined associations between specific forms of positive and negative emotional reactivity at age 5, children?s effortful control (EC), emotion regulation, and social skills at age 7, and adolescent functioning across psychological, academic, and physical health domains at ages 15/16 (N = 383). We examined how distinct components of childhood emotional reactivity directly and indirectly predict domain-specific forms of adolescent adjustment, thereby identifying developmental pathways between specific types of emotional reactivity and adjustment above and beyond the propensity to express other forms of emotional reactivity. Age 5 high-intensity positivity was associated with lower age 7 EC and more adolescent risk-taking; age 5 low-intensity positivity was associated with better age 7 EC and adolescent cardiovascular health, providing evidence for the heterogeneity of positive emotional reactivity. Indirect effects indicated that children?s age 7 social skills partially explain several associations between age 5 fear and anger reactivity and adolescent adjustment. Moreover, age 5 anger reactivity, low-, and high-intensity positivity were associated with adolescent adjustment via age 7 EC. The findings from this interdisciplinary, long-term longitudinal study have significant implications for prevention and intervention work aiming to understand the role of emotional reactivity in the etiology of adjustment and psychopathology.

A polygenic score for age-at-first-birth predicts disinhibition / Leah S. RICHMOND-RAKERD in Journal of Child Psychology and Psychiatry, 61-12 (December 2020)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 61-12 (December 2020) . - p.1349-1359 Titre : A polygenic score for age-at-first-birth predicts disinhibition Type de document : Texte imprimé et/ou numérique Auteurs : Leah S.

However, the meaning of these genetic discoveries is unclear. Drawing on evidence linking early pregnancy with disinhibitory behavior, we tested the hypothesis that genetic discoveries for age-at-first-birth predict disinhibition. METHODS: We included participants with genotype data from the two-decade-long Environmental Risk (E-Risk) Study (N = 1,999) and the four-decade-long Dunedin Study (N = 918). We calculated a genome-wide polygenic score for age-at-first-birth and tested whether it was associated with a range of disinhibitory outcomes across the life course, including low childhood self-control; risk for externalizing psychopathology; officially recorded criminal offending; substance dependence; informant reports of disinhibitory problems; and number of lifetime sexual partners. We further tested whether associations were attributable to accelerated pubertal maturation. RESULTS: In both cohorts, the age-at-first-birth polygenic score predicted low childhood self-control, externalizing psychopathology, officially recorded criminal offending, substance dependence, and number of sexual partners. Associations were modest, but robust across replication. Childhood disinhibition partly mediated associations between the polygenic score and reproductive behaviors. In contrast, associations were not attributable to accelerated pubertal timing. CONCLUSIONS: Genomic discoveries for age-at-first-birth are about more than reproductive biology: They provide insight into the disinhibitory traits and behaviors that accompany early parenthood. Age-at-first-birth is a useful proxy phenotype for researchers interested in disinhibition. Further, interventions that improve self-regulation abilities may benefit young parents and their children.
