Inhibitory Control During Emotional Distraction Across Adolescence and Early Adulthood

This study investigated the changing relation between emotion and inhibitory control during adolescence. One hundred participants between 11 and 25 years of age performed a go‐nogo task in which task‐relevant stimuli (letters) were presented at the center of large task‐irrelevant images depicting negative, positive, or neutral scenes selected from the International Affective Picture System. Longer reaction times for negative trials were found across all age groups, suggesting that negative but not positive emotional images captured attention across this age range. However, age differences in accuracy on inhibitory trials suggest that response inhibition is more readily disrupted by negative emotional distraction in early adolescence relative to late childhood, late adolescence, or early adulthood.     

Contributions of Reward Sensitivity to Ventral Striatum Activity Across Adolescence and Early Adulthood

It was examined how ventral striatum responses to rewards develop across adolescence and early adulthood and how individual differences in state‐ and trait‐level reward sensitivity are related to these changes. Participants (aged 8–29 years) were tested across three waves separated by 2 years (693 functional MRI scans) in an accelerated longitudinal design. The results confirmed an adolescent peak in reward‐related ventral striatum, specifically nucleus accumbens, activity. In early to mid‐adolescence, increases in reward activation were related to trait‐level reward drive. In mid‐adolescence to early adulthood decreases in reward activation were related to decreases in state‐level hedonic reward pleasure. This study demonstrates that state‐ and trait‐level reward sensitivity account for reward‐related ventral striatum activity in different phases of adolescence and early adulthood.     

Distinct Age‐Related Differences in Temporal Discounting and Risk Taking in Adolescents and Young Adults

Age‐related differences in temporal discounting (TD) and risk taking, and their association, were examined in adolescents and young adults (n = 337) aged 12–27 years. Since monetary rewards are typically used in TD and risk‐taking tasks, the association between monetary reward valuation and age and decision making in these tasks was explored as well. TD declined linearly with age, with a particularly sharp decline from 15 to 16 years. In contrast, risk taking was not correlated with age and TD. Reward valuation was not associated with TD and risk taking, and age‐related differences in TD remained significant after controlling for reward valuation. Together, these findings suggest that risk taking and TD are two separate constructs with distinct age‐related differences in adolescence and young adulthood.     

Development of Multifaceted Risk Taking and the Relations to Sex Steroid Hormones: A Longitudinal Study

Risk taking is a multidimensional construct. It is currently unclear which aspects of risk‐taking change most during adolescence and if/how sex hormones contribute to risk‐taking tendencies. This study applied a longitudinal design with three time‐points, separated by 2 years, in participants aged 8–29 years (670 observations). The Balloon Analogue Risk Task, a delay discounting task, and various self‐report questionnaires were administered, to measure aspects of risk taking. Longitudinal analyses demonstrated mostly nonlinear age‐related patterns in risk‐taking behavior and approach‐related personality characteristics (peaking in late adolescence). Increased testosterone and estradiol were found to increase risk‐taking behavior and impulsive personality, but decrease avoidance‐like personality. This study demonstrates that risk taking is most pronounced in mid‐to‐late adolescence and suggests that sex hormones accelerate this maturational process.     

Continuity and Discontinuity in Perceptions of Family Relationships From Adolescence to Young Adulthood

The present 8‐year longitudinal study examined how multiple aspects of family relationships change across the transition from adolescence (M_age = 15 years) to young adulthood (M_age = 22 years) among 821 individuals. Results showed that there was more discontinuity than continuity in family relationships across this transition. Whereas a normative decline was evident in all measured aspects of family relationships during adolescence, this decline persisted for only a few dimensions of family relationships during young adulthood. Other aspects of family relationships stabilized or rebounded. There was little variation in these trajectories as a function of ethnicity or gender, suggesting that these changes in family relationships are generally normative. Results suggest that the transition to adulthood is a period of significant transformation in family relationships.     

Temperamental sensitivity to early maltreatment and later family cohesion for externalizing behaviors in youth adopted from foster care

Children in foster care frequently have histories of physical/sexual abuse and neglect, increasing their risk for externalizing behaviors (EB; e.g., aggression). According to the differential susceptibility theory, children with reactive temperaments (e.g., negative emotionality) may be particularly vulnerable to early maltreatment, but may also benefit the most from environmental enrichment such as family cohesion. In a high-risk longitudinal sample of 82 children adopted from foster care in Los Angeles County from 1996 and 2001, we examined predictions of EB from childhood to adolescence/young adulthood from temperament, preadoption maltreatment, and adoptive family cohesion. Overall, results from generalized linear models and generalized estimating equations (GEE) did not support differential susceptibility theory – specifically, youth with early reactive temperament did not exhibit heightened sensitivity to maltreatment nor to later adoptive family cohesion. Instead, reactive temperament was associated with higher EB at initial adoptive placement and escalating EB across childhood, controlling for age, gender, race-ethnicity, preadoption maltreatment, and adoptive family cohesion. Preadoption maltreatment history was unrelated to baseline EB, although sexual abuse history predicted escalating childhood EB post-adoption, whereas exposure to family violence (e.g., domestic violence) inversely predicted EB over time. By late adolescence/young adulthood 11–15 years post-adoption, rates of arrest and substance use in this sample were relatively comparable to normative populations of youth, although older age of adoption predicted more substance use in late adolescence/young adulthood. Findings highlight early reactive temperament and preadoption maltreatment as important risk factors to target for ameliorating patterns of EB growth in the first few years of adoption.     

Relationship Reciprocation Modulates Resource Allocation in Adolescent Social Networks: Developmental Effects

Adolescence is characterized as a period of social reorientation toward peer relationships, entailing the emergence of sophisticated social abilities. Two studies (Study 1: N = 42, ages 13–17; Study 2: N = 81, ages 13–16) investigated age group differences in the impact of relationship reciprocation within school‐based social networks on an experimental measure of cooperation behavior. Results suggest development between mid‐ and late adolescence in the extent to which reciprocation of social ties predicted resource allocation. With increasing age group, investment decisions increasingly reflected the degree to which peers reciprocated feelings of friendship. This result may reflect social‐cognitive development, which could facilitate the ability to navigate an increasingly complex social world in adolescence and promote positive and enduring relationships into adulthood.     

Socio-Economic Gradients and Disability During The Transition to Young Adulthood: A Longitudinal Survey and Register Study in Norway

The study aimed to investigate trends and explanatory factors for socio-economic inequalities associated with disability during the transition to young adulthood. A sample of 2606 participants (56% females and 44% males) was prospectively followed from adolescence to young adulthood. Disability status, age, gender, mental health problems, scholastic competence and social acceptance were measured from the longitudinal survey Young in Norway, while socio-economic indicators such as participants’ and their parents’ levels of education, annual income, unemployment and welfare benefits were extracted from the National Population Register in Norway. Regression models were applied to estimate associations between disability and socio-economic outcomes. The findings show that disabled adolescents have a significantly greater risk of achieving lower levels of education and are unemployed and over-represented in welfare benefits during the transition to young adulthood. Most of these associations between disability and socio-economic outcomes were explained by mental wellbeing and self-perceptions. The study suggests that interventions addressing mental wellbeing and social competence might reduce the development of socio-economic inequalities among young people with disability.     

Adolescent maltreatment and its impact on young adult antisocial behavior

STATEMENT OF PROBLEM: Childhood maltreatment is known to be a risk factor for a range of later problems, but much less is known about adolescent maltreatment. The present study aims to investigate the impact of adolescent maltreatment on antisocial behavior, while controlling for prior levels of problem behavior as well as sociodemographic characteristics. METHODS: Data are from the Rochester Youth Development Study, a cohort study of the development of problem behaviors in a sample of 1,000 urban youth followed from age 13 into adulthood. Subjects include 68% African American, 17% Hispanic, and 15% White youth. This analysis includes a maximum of 884 subjects, of whom 9.3% had substantiated maltreatment reports in adolescence. Among the maltreated adolescents, 14 experienced sex abuse, 36 experienced physical abuse, and 32 were neglected or emotionally abused. Outcomes explored in late adolescence (ages 16-18) and young adulthood (ages 20-22) include arrest, self-reported general and violent offending, and illicit drug use. Control variables include prior levels of these outcomes as well as sociodemographic characteristics like poverty, parent education, and caregiver changes. RESULTS: Logistic regression analysis determined that experiencing any substantiated maltreatment during adolescence increases the odds of arrest, general and violent offending, and illicit drug use in young adulthood, even controlling for sociodemographic characteristics and prior levels of problem behavior. Different types of adolescent maltreatment, including neglect, appear to produce similar adverse behavioral consequences. CONCLUSIONS: Adolescent maltreatment necessitates increased attention in view of its enduring and potentially wide-ranging impact on the life span.     

Drug use and personality in adolescence and young adulthood: structural models with nonnormal variables

An introduction to structural modeling with nonnormal continuous variables is provided using the equations language of the micro-mainframe program EQS in the context of a longitudinal study of adolescent development that followed about 700 adolescents across an 8-year span into young adulthood. 2 models relating drug use and personality are developed to assess the influence of drug use on personality, and personality on drug use. A high level of self-acceptance is shown to have a small but significant inoculating effect against subsequent cannabis use in both early and late adolescence, while a small positive effect of cannabis use on subsequent self-acceptance occurs only during early adolescence. Substantial stability of self-derogation, cannabis use, and law abidance are demonstrated, with self-derogation during adolescence leading to increased law abidance during young adulthood.     

Separating the fish from the sharks: a longitudinal study of preschool response inhibition

The development of response inhibition was investigated using a computerized go/no‐go task, in a lagged sequential design where 376 preschool children were assessed repeatedly between 3.0 and 5.25 years of age. Growth curve modeling was used to examine change in performance and predictors of individual differences. The most pronounced change was observed between 3 and 3.75 years. Better working memory and general cognitive ability were related to more accurate performance at all ages, but relations with speed changed with age, where better cognitive skills were initially related to slower responding, but faster responding at later ages. Boys responded more quickly and were more accurate on go trials, whereas girls were better able to withhold responding on no‐go trials.     

Age differences in strategic planning as indexed by the tower of London

The present study examined age differences in performance on the Tower of London, a measure of strategic planning, in a diverse sample of 890 individuals between the ages of 10 and 30. Although mature performance was attained by age 17 on relatively easy problems, performance on the hardest problems showed improvements into the early 20s. Furthermore, whereas age-related performance gains by children and adolescents (ages 10-17) on the hardest problems were partially mediated by maturational improvements in both working memory and impulse control, improved performance in adulthood (ages 18+) was fully mediated by late gains in impulse control. Findings support an emerging picture of late adolescence as a time of continuing improvement in planned, goal-directed behavior.     

Predictors of resilience in abused and neglected children grown-up: the role of individual and neighborhood characteristics

PURPOSE: This paper examines individual, family, and neighborhood level predictors of resilience in adolescence and young adulthood and describes changes in resilience over time from adolescence to young adulthood in abused and neglected children grown up. METHOD: We use documented cases of childhood physical and sexual abuse and neglect (n=676) from a Midwestern county area during the years 1967-1971 and information from official records, census data, psychiatric assessments, and self-reports obtained through 1995. Analyses involve logistic regressions, replicated with Mplus to test for possible contextual effects. RESULTS: Almost half (48%) of the abused and neglected children in adolescence and nearly one-third in young adulthood were resilient. Over half of those who were resilient in adolescence remained resilient in young adulthood, whereas 11% of the non-resilient adolescents were resilient in young adulthood. Females were more likely to be resilient during both time periods. Being white, non-Hispanic decreased and growing up in a stable living situation increased the likelihood of resilience in adolescence, but not in young adulthood. Stressful life events and a supportive partner promoted resilience in young adulthood. Neighborhood advantage did not exert a direct effect on resilience, but moderated the relationship between household stability and resilience in adolescence and between cognitive ability and resilience in young adulthood. CONCLUSIONS: Ecological factors appear to promote or interfere with the emergence and stability of resilience following childhood maltreatment.     

Maturation of cognitive processes from late childhood to adulthood

To characterize cognitive maturation through adolescence, processing speed, voluntary response suppression, and spatial working memory were measured in 8- to 30-year-old (N = 245) healthy participants using oculomotor tasks. Development progressed with a steep initial improvement in performance followed by stabilization in adolescence. Adult-level mature performance began at approximately 15, 14, and 19 years of age for processing speed, response inhibition, and working memory, respectively. Although processes developed independently, processing speed influenced the development of working memory whereas the development of response suppression and working memory were interdependent. These results indicate that processing speed, voluntary response suppression, and working memory mature through late childhood and into adolescence. How brain maturation specific to adolescence may support cognitive maturation is discussed.     

Why Don’t Smart Teens Have Sex? A Behavioral Genetic Approach

Academic achievement and cognitive ability have been shown to predict later age at first sexual intercourse. Using a sample of 536 same-sex twin pairs who were followed longitudinally from adolescence to early adulthood, this study tested whether relations between intelligence, academic achievement, and age at first sex were due to unmeasured genetic and environmental differences between families. Twins who differed in their intelligence or their academic achievement did not differ in their age at first sex. Rather, the association between intelligence and age at first sex could be attributed entirely to unmeasured environmental differences between families, whereas the association between academic achievement and age at first sex could be attributed entirely to genetic factors.     

Response Time Adjustment in the Stop Signal Task: Development in Children and Adolescents

Adjusting speed to maintain fast and accurate performance is critical to goal-directed behavior. This study examined development of response time adjustments in the stop signal task in 13,709 individuals aged 6–17 years (49.0% Caucasian) across four trial types: correct and incorrect go, successful (stop-inhibit), and failed (stop-respond) trials. People sped more after correct than incorrect go responses and slowed more after failed than successful stop trials. Greater slowing after stop-respond but less slowing after stop-inhibit trials was associated with better response inhibition. Response time adjustments were evident in children as young as age 6, developed throughout childhood, and plateaued by age 10. Results were consistent with the predictions of the error detection and shifting goal priority hypotheses for adjustments.     

Differences between residential and non-residential fathers on sexual socialisation of African American youth

This study investigated differences between residential and non-residential fathers on topics discussed during father–child sex communication and factors associated with child sexual socialisation. Young people (N = 159, 53% female) provided self-reports using computer surveys on the role of their fathers on father–child sex communication, general communication, parental monitoring, father social support and topics discussed during father–child sex communication. The analysis revealed differences in topics discussed between young people with residential vs. non-residential fathers. Independent group t-tests revealed significant differences between young people with residential vs. non-residential fathers on social support and parental monitoring for sons and parental monitoring for daughters. Sons and daughters with residential fathers had higher scores on these variables. Discriminant function analyses, chi-square tests and hierarchical linear regression analyses were carried out to determine whether there were meaningful distinctions between young people with residential vs. non-residential fathers. The analysis revealed social support and parental monitoring provided the most meaningful distinction between young people with residential vs. non-residential fathers. These results highlight the importance of non-residential fathers in the sexual socialisation of their young people through parent–child sex communication. Discussion focuses on the need for development of interventions to promote the inclusion of non-residential fathers in the sexual socialisation of African American youth.     

Women Face Unemployment: A Comparative Analysis of Age Groups

The study examined differences in job search intensity, attitudes toward unemployment, and related responses among four age groups of jobless women in Israel, all of whom were married: Post-adolescence (up to age 21); young adulthood (age 22–35), mid-life (age 36–49); and late adulthood (50–62). The findings revealed differences in job search intensity for the four age groups. The youngest group spent more time seeking employment per week than did the other groups. At the same time, women in the late adulthood group were least likely to reject job offers owing to financial considerations, whereas those in the young adult and mid-life groups tended to reject job offers either due to conflict with family obligations or to work conditions. Moreover, the older respondents reported a sharper decline in health following unemployment than did their younger counterparts. In the same vein, members of the late adulthood group reported less financial strain as a result of unemployment than did the rest of the groups.     

Small-group collaboration and individual knowledge acquisition: The processes of growth during adolescence and early adulthood

Research into small-group collaboration during middle to late childhood shows that while individual understanding can be promoted through exchanging differing opinions, the joint analyses that groups construct while collaborating play a tangential role. Individuals may or may not accept these constructions depending upon processes of reflection and reconciliation that are triggered through difference and sometimes occur post-group. Recognizing a dearth of research with older participants (together with inconclusive suggestions that collaborative constructions may become more significant with age), the reported study examines the impact of small-group collaboration during adolescence and early adulthood. Forty-six pairs of students aged between 10 and 22 years worked on a computer-presented task that required them to discuss and predict the trajectories objects follow when they fall from stationary or moving carriers. Associations between group dialogue and post-test performance confirmed a key role for differing opinions while collaborative constructions turned out to have little relevance.     

A qualitative study of specialist schools’ processes of eliciting the views of young people with autism spectrum disorders in planning their transition to adulthood

Government legislation and research literature highlight the importance of the participation of pupils with autistic spectrum disorders (ASD) in planning for their transition to adulthood. However, effective processes which enable their participation are under‐researched. In this study, nine teaching staff from two specialist schools in the north‐west of England were interviewed and a transition meeting was observed in one school to explore these processes. Analyses indicate that in both schools, enabling the participation of young people with ASD in the planning for their transition to adulthood involves three phases and is underpinned by a person‐centred ethos. Although the processes were perceived to be effective, the participation of pupils varied between schools. Final decisions still tend to be made by schools and the local authority due to limited external resources. The implications of these findings are discussed.
