Children in sync: exploring how interpersonal synchrony experience induces cooperation between child peers.

Synchronous interpersonal movements induce positive prosocial behaviors in adults and children. The processes that underlie this are debated. Here, we investigate the extent to which visual cues available during synchrony experience-particularly shared facial expressions and mutual eye contact-are necessary.

The role of caregiver emotion regulation in youth mental health during the COVID-19 pandemic: A longitudinal study.

The COVID-19 pandemic has presented youth and families with a broad spectrum of unique stressors. Given that adolescents are at increased risk for mental health and emotional difficulties, it is critical to explore family processes that confer resilience for youth in the face of stress. The current study investigated caregiver emotion regulation (ER) as a familial factor contributing to youth ER and risk for psychopathology following stressful life events.

National disparities favoring males are reflected in girls' implicit associations about gender and academic subjects.

Based on data for = 2,756 children (1,410 girls; = 8.10 years) from 16 data sets spanning five nations, this study investigated relations between national gender disparities and children's beliefs about gender and academic subjects. One national-level gender disparity involved inequalities in socioeconomic standing favoring adult males over females (U.

Opportunity to view the starry night sky is linked to human emotion and behavioral interest in astronomy.

Prior to the modern era, the stars in the night sky were readily visible across the globe, but light pollution has created disparities in the opportunity to see these astronomical objects with the naked eye. This alteration may measurably impact human behavior. We hypothesize that light pollution is related to the development of people's interest in astronomy, which often serves as a "gateway" to science more broadly.

Heart-to-heart: infant heart rate at 3 months is linked to infant-directed speech, mother-infant interaction, and later language outcomes.

Introduction: Previous studies underscore the importance of speech input, particularly infant-directed speech (IDS) during one-on-one (1:1) parent-infant interaction, for child language development. We hypothesize that infants' attention to speech input, specifically IDS, supports language acquisition. In infants, attention and orienting responses are associated with heart rate deceleration.
