Although scientific reasoning is not a formal, independent school subject, it is an increasingly important skill, especially for student learning in science, technology, engineering, and mathematics (STEM) subjects.

Loneliness is a stressful experience that appears to interfere with health and social integration (SI). Recently, researchers proposed that both antecedents and consequences of loneliness may change across the life span.

General well-being is known to deteriorate sharply at the end of life. However, it is an open question how rates of terminal change differ across affective and evaluative facets of well-being and if individual difference correlates operate in facet-specific ways. We examined how discrete affective states (happy, angry, fearful, sad) and…

This study investigated age differences in longitudinal effects of volunteering on three facets of subjective well-being (SWB), i.e. positive affect (PA), negative affect (NA), and life satisfaction (LS). Both direct and indirect effects with self-efficacy as mediator were tested. Longitudinal structural equation modeling was used on 5,564…

A sample was drawn from 290 cities in Germany which was stratified according to four age groups (18-25, 40-54, 55-69, and 70-85), gender and…

A study of German-speaking kindergartners and adults replicated Canadian research that found that, although children made more errors than adults in recognizing emotional expressions of photographed faces, they structured emotional concepts just as adults did. (Author/BB)
