Few studies on the development of forgiveness involved young children and adolescents, and very few involved samples from non-western countries. This study focused on the development of willingness to forgive a particular transgression in participants aged 4 to 12 years and from two different cultures: a South African culture (Mozambique) and a…

In this longitudinal study, we investigated the factor structure and stability of early-life temperament in a German sample, using three measures developed within Rothbart's psychobiological approach. Temperament was measured using the Infant Behavior Questionnaire Revised (IBQ-R) at the ages of 6 and 12 months, the Early Childhood Behavior…

The current study examined to what extent face and speech processing interact with each other and whether they enhance or impair the processing of the other in 5-year-olds (n = 51) and adults (n = 34). Using a computer-based speeded sorting task allowed to directly test the influence of auditory speech on face processing and the influence of face…

Prospective memory (PM) refers to the ability to remember and complete planned tasks in the future, which relies on working memory (WM) for encoding and maintaining the intention. Implementation intention is a useful strategy for improving PM function in adults. Yet the effect of implementation intentions in children, and whether factors such as…

Understanding of preterm infant cognitive competences across the first year of life is limited regarding the developmental constructs of continuity, stability, coherence, and predictive validity as well as how they manifest by age and country of origin. This prospective longitudinal study examined and compared mean-level continuity,…

This longitudinal study explores the associations between children's executive functions at the beginning of preschool and their learning behaviors, namely competence motivation and attentional persistence, at the end of preschool. Participants were 218 Portuguese children (M[subscript age]= 40.4 months, SD= 4.2; 52% boys) and their preschool…

Climate change worry (CCW) is a specific worry about climate change, involving thoughts about changes that might occur in the climate system and their possible effects. Nowadays, it is growing especially among adolescents. As there is a lack of measurement tools with adequate psychometric properties to assess CCW in this age group, we investigated…

In everyday life, individuals often need to make choices about the difficulty level of tasks they wish to perform. Here, we investigate age- and gender-related differences in the monitoring of discrepancies between the difficulty of a given task and one's own performance level, and in the likelihood to select task difficulties that match one's…

Effortful control, the ability to suppress a dominant response over a subdominant one, is a fundamental aspect of self-regulation. It has been observed that higher levels of parenting stress are associated with lower levels of effortful control in children. Perceived social support, an important factor in reducing parenting stress, may act as a…

Previous research suggests that age-related differences in pro-environmental behavior (PEB) and the emotional reactions to climate change could originate from generational as well as aging effects and can be influenced by the opportunities and constraints of life circumstances and resources. The current research aimed to better understand age…

To illuminate individual differences in the development of attention-deficit hyperactivity disorder (ADHD) symptoms in the general population, psychometric measures are needed that can capture general population-level symptom variation reliably, validly, and comparably from childhood through to the transition to adulthood. The ADHD subscale of the…

Self-report research indicates that dishonesty decreases across adulthood; however, behavioral measures of dishonesty have yet to be examined across younger and older adults. The present study examined younger and older adults' cheating behaviors in relation to their self-reported honesty-humility. Younger (N = 112) and older adults (N = 85)…

We examined Canadian host-society children's prosociality (i.e., emotions and behaviors that reflect care for the welfare of others) toward refugee newcomer peers and the role of parental socialization (i.e., frequency of parent-child conversations about refugee newcomers) in children's refugee-specific prosociality. The sample included 168…

Economic inequality has been consistently rising in recent decades in many Western countries including Germany. This is a pressing issue as greater economic inequality within a society has detrimental consequences for well-being, social stability, productivity, and even life expectancy. However, little is known about how individuals of different…

Trajectories of perceived stress from the transition to adulthood (age 25), during young adulthood (age 32), and into midlife (ages 43 and 50) were examined with four waves of longitudinal survey data (N = 688; 49% female, 37% with a university degree, 86% White). We explored how between- and within-person variation in perceived stress was…
