In this study, we examined whether adolescents helped others during the COVID-19 pandemic and how stories in the media inspired them in doing so. Using an online daily diary design, 481 younger adolescents ( M = 15.29, SD = 1.76) and 404 older adolescents ( M = 21.48, SD = 1.91) were followed for 2 weeks. Findings from linear mixed effects models d...

Adolescents are often characterized as impulsive. This study took the novel perspective of testing impulsivity in a fMRI task where choices could affect outcomes for adolescents’ themselves and their best friend. Participants were 96 adolescents (aged 10-19) who performed a temporal discounting task with rewards for either themselves (i.e., the Sel...

In the present longitudinal study, we explored adolescents’ mood trajectories throughout the pandemic, and whether vu...

The current longitudinal study examined two aims: (1) the short- and long-term effects of the pandemic on young people’s mood (i.e. vigor, tension, and depression levels) and emotional reactivity (i.e. fluctuations in daily mood), and (2)...

Background: Although most young people do not become seriously ill from the coronavirus causing the COVID-19 disease, they do play a role in its spread. It is therefore important that they adhere to the recommended preventive behaviors, most importantly, physical distancing. This study aims to gain a better understanding of the psychosocial determi...

In this study, we examined whether adolescents and young adults help others during the COVID-19 pandemic and how stories in the media can inspire them in doing so. For this online daily diary study, 481 adolescents (M = 15.29, SD = 1.76) and 404 young adults (M = 21.48, SD = 1.91) were followed for two weeks. Findings of linear mixed effects models...

The current longitudinal study examined the impact of the pandemic on young people’s mood, emotional reactivity, and wellbeing (i.e., operationalized as balancing needs of self and others). Hence, we conducted an online two-week daily dia...

Analogical reasoning is assumed to play a large role in learning and problem solving in everyday and school settings. It was examined whether a newly developed dynamic test of analogical reasoning would be sufficiently difficult for identifying young gifted children’s potential for solving analogies. The study included 74 gifted (n = 31) and averag...

In doing so, it was analysed whether planning, a higher-order executive function, was related to outcomes of the dynamic test, and to instructi...
