Emotion transmission in peer dyads in middle childhood.

This study investigated emotion transmission among peers during middle childhood. Participants included 202 children (111 males; race: 58% African American, 20% European American, 16% Mixed race, 1% Asian American, and 5% Other; ethnicity: 23% Latino(a) and 77% Not Latino(a); Mincome = $42,183, SDincome = $43,889; Mage = 9.49; English‐speaking; from urban and suburban areas of a mid‐Atlantic state in the United States). Groups of four same‐sex children interacted in round‐robin dyads in 5‐min tasks during 2015–2017. Emotions (happy, sad, angry, anxious, and neutral) were coded and represented as percentages of 30‐s intervals. Analyses assessed whether children's emotion expression in one interval predicted change in partners' emotion expression in the next interval. Findings suggested: (a) escalation of positive and negative emotion [children's positive (negative) emotion predicts an increase in partners' positive (negative) emotion], and (b) de‐escalation of positive and negative emotion (children's neutral emotion predicts a decrease in partners' positive or negative emotion). Importantly, de‐escalation involved children's display of neutral emotion and not oppositely valenced emotion. [ABSTRACT FROM AUTHOR]
