When deciding whether to trust someone's claims, how do children combine - over multiple interactions - information about that person's general behavioral tendencies (traits) with that person's ongoing (and changing) rate of providing accurate claims? Children aged 4-8 played 11 rounds of a find-the-sticker game. For each round, an informant…

Because sequential patterns of multiple transition events (i.e., college graduation, full-time employment, marriage, and parenthood) are associated with turning points in depressive symptom trajectories during young adulthood, the present study used a sample of 446 White adolescents (52.3% females; 15.58 years old, on average) over 18 years (1992…

This study examined age-related patterns in exposure and affective reactivity to daily stressors across a 20-year time span among adults who were between 22 and 77 years old at their baseline interview. Longitudinal data from the National Study of Daily Experiences (NSDE) consisted of three bursts of eight consecutive nightly interviews of stress…

Adults often prefer things that they believe are natural, including natural foods. This preference has serious implications, such as the rejection of cultured meat and other sustainable technologies. Here we explore whether children also prefer natural foods. We conducted two preregistered studies with 374 adults and children from the United…

The aim of the study was to examine associations between life events and self-assessed loneliness in adolescence. We used data from a Norwegian population-based twin sample including seven birth cohorts (N = 2,879, 56% females). The participants completed self-report questionnaires three times throughout adolescence, with 2 years in between (i.e.,…

We investigated whether selective discussion of autobiographical memory narratives would impact the quality of young people's recall of their nondiscussed memory narratives. Children (ages 8-9 years, n = 65) and adolescents (ages 13-15 years, n = 58) completed an adapted version of the retrieval-induced forgetting (RIF) paradigm for self-generated…

Telomeres are the protective DNA-protein sequences appearing at the ends of chromosomes; they shorten with each cell division and are considered a biomarker of aging. Shorter telomere length and greater erosion have been associated with compromised physical and mental health and are hypothesized to be affected by early life stress. In the latter…

Little research has examined changes in personal identity over different periods of adult development. The aim of the present cross-sectional study was to target these changes through the characterization of the main dimensions in self-defining memories (SDMs; thematic content, specificity, integrative meaning, tension, contamination/redemption,…

Many developmental theories have not been sufficiently evaluated using designs that control for unobserved familial confounds. Our long-term goal is to determine the causal structure underlying associations between early environmental conditions and later psychosocial and health outcomes. Our overall objective in this study was to further evaluate…

Increasing research shows pubertal development accelerates following threats while it decelerates following deprivation. Yet, these environmental stressors are unlikely to occur in isolation. We investigated how war exposure and energetic stress impact pubertal development using data from the longitudinal Biological Pathways of Risk and Resilience…

For lesbian, gay, bisexual, or queer (i.e., sexual minority [SM]) youth, coming out is an important developmental milestone and is typically associated with positive well-being. However, coming out in high school may entail a higher risk of school-based victimization. Due to the greater risk of homophobic bullying, the implications of being out in…

Executive function (EF) has rarely been considered for adolescents' daily school outcomes or in conjunction with ethnic/racial discrimination. Using 2-week, daily data from 137 ethnic/racial minority adolescents (M[subscript age] = 14.56; 53% female; 56% Black, 19% Latinx, 7% Asian, 7% Native, 12% other [e.g., multiracial]) in the Midwest United…

Moral pride is a key component of virtue development. This study provides developmental insight into children's moral pride across cultures, and the potential for moral pride to underlie prosocial behavior. Participants included children and adolescents ages 6, 9, and 12 years from Canada (n = 186; 50% girls; ethnically diverse sample), Japan (n =…

This study examined relations of affinity for solitude with social-behavioral, academic, and psychological adjustment in Chinese children and adolescents. The participants included 3,417 students (1,714 boys) in fourth, sixth, and eighth grades (M[subscript ages] = 10, 12, and 14 years, respectively) in China. Data on affinity for solitude were…

Childhood adversity can have detrimental impacts on life course mental and physical health. Timing, nature, severity, and chronicity of adversity are thought to explain much of the variability in health and developmental outcomes among exposed individuals. The current study seeks to characterize heterogeneity in adverse experiences over time at…
