Although children display strong individual differences in emotion expression, they also engage in emotional synchrony or reciprocity with interaction partners. To understand this paradox between trait-like and dyadic influences, the goal of the current study was to investigate children's emotion expression using a Social Relations Model (SRM)…

The experience of love plays an integral role in human development as adolescents transition into adulthood. However, little is known about whether early adults have a shared understanding about indicators of love in daily life in this transitional phase. Using Cultural Consensus Theory informed by developmental theory, this study examined whether…

The sustainability motive-alignment hypothesis posits that adolescents will be motivated to act sustainably when they view sustainable behavior as aligned with their motives for autonomy and peer status. Based on this hypothesis, we developed the Sustainability Motive-Alignment Scale (SMAS), a brief self-report scale of individual differences in…

Animal-assisted interventions (AAI) are increasingly used in clinical and school settings to promote psychological and social-emotional well-being among youth. However, the precise role of youth-animal relationships in shaping developmental trajectories is understudied. Research is needed to expand human-centric models of child development,…

Despite the growing attention to online social comparison, most studies have focused on the psycho-emotional implications of the behavior, leaving the identity implications ambiguous. Given the importance of identity development and the prevalence of social media use among emerging adults going through college transition, this study explored how…

The transitional years of early adulthood, with key tasks of identity and intimacy development, engender both opportunities and risks for well-being. We propose that the conceptualization and measurement of early adults' well-being can be improved through (a) an integration of ideas from developmental and psychological science on well-being, (b)…

A minimal amount is known regarding the mechanisms underlying the potential benefits of extracurricular activities (ECAs) for adolescents' psychological adjustment. This preliminary cross-sectional study, during which 512 undergraduates retrospectively reported information about high school ECAs, used structural equation modeling to show that…

This study aimed to examine the unique and joint contributions of behavioral and emotional self-regulation to key but understudied emergent literacy and early social skills, disentangling sex-differentiated paths. The participants were 231 Portuguese preschoolers (50% boys; M[subscript age] = 59.5 months; SD = 8.5) enrolled in 47 classrooms. In…

To examine whether trajectories of participation in organized activities during the high school years and beyond (from ages 14 to 20) predicted outcomes at age 21 (externalizing problems, internalizing problems, civic engagement, number of years of education, and perception of physical health), 354 youths (60% girls) were surveyed annually over…

Youth who form bonds with supportive, nonparent adults within their existing social networks (i.e., natural mentors) experience a range of positive outcomes, but a relatively minimal amount is known regarding the psychosocial factors that prospectively predict the formation of natural mentoring relationships. Analyzing longitudinal youth data from…

The aim of this manuscript is to examine the perceived parental perfectionism in undergraduate Italian students. Study 1 aimed at exploring the factorial structure, reliability, and construct validity of the Italian version of the Family Almost Perfect Scale (FAPS). The aim of Study 2 was to cross-validate the FAPS structure with a different…

In this study, we compared the time perspectives of runaway and nonrunaway adolescents by examining relationships among time perspective, psychological outcomes, and risky behavior within runaways. Participants included 163 runaway and 581 nonrunaway adolescents who completed a self-report survey. Several dimensions of time perspective were…

Different positive effects of interactions with animals, such as reduction of stress reactions, depressive mood, anxiety, aggression, and pain, and promotion of trust, calmness, motivation, and concentration have been documented by research on human-animal interaction (HAI), including animal assisted interventions (AAIs). Potential biological,…

In this article, we explore how researchers can more fully consider and conceptualize the role of race and ethnicity in studies of youth development programs, with an emphasis on positive youth development (PYD). Such a focus can be integrated in a more meaningful way through the application of a theoretical model that provides a framework for…

In this study, we examined the characteristics of adolescents' deep interests or "sparks," the role of relationships in supporting the development of sparks, and whether having a spark was associated with positive developmental outcomes. Participants included 1,860 15 years olds from across the United States who participated in the…
