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…

Parents' cultural beliefs are associated with their children's socialization and development. Researchers have examined these associations through the lens of parents' ethnotheories, which refer to parents' implicit beliefs about children's developmentally appropriate behavior. In contrast to prior work focused on parents' ethnotheories of…

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…

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…

Across all cultures, parents have intuitive ideas ("ethnotheories") of what undesirable child characteristics are as well as how to explain them. Yet there have been relatively few cross-cultural comparisons of parents' ethnotheories about the nature and causes of child misbehavior. 108 mothers of 5-year-old children from the United…

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…

Narrative story stem techniques (NSSTs) offer insight into attachment and other representational aspects of preschool to young school aged children's inner lives. While the method moved into the academic and clinical mainstream some 35 years ago, their applicability to "non-Western" contexts remains little understood. This synthesis…

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,…

Longitudinal studies provide developmental science with invaluable information about how variables and the associations between variables change across time, but typically give limited attention to the length of time over which that change occurs. The present study re-analyzed data from previously published meta-analyses of longitudinal data…

Knowing about emotions is vital for children's school adjustment, well-being, and future social relationships. Whereas experiencing emotions is a universal psychological process at the biological level, how emotions are categorized and communicated is shaped by culture. Most studies have investigated cultural differences in emotion (knowledge) in…

Given the developmental benefits associated with higher sense of purpose, past work has aimed to understand how experiences of adversity relate to sense of purpose. With a specific focus on experiences of adversity that may impact individuals from marginalized groups, past work has found that discrimination is related to lower sense of purpose in…

Theorized mechanisms linking views on aging, self-regulation, and well-being have not previously been examined longitudinally. This study considers goal re-engagement as a potential mediator of longitudinal relationships between awareness of age-related change (AARC) and vitality. We expected that more positive perceptions of aging (i.e., higher…

Globally, one in three women experiences domestic violence over their lifetimes. Yet, the factors that shape adult behavior toward domestic violence remain poorly understood. We examine the effect of exposure to political violence in early stages of life on likelihood of domestic violence in marital life. Combining household level survey with…
