Toddler Exuberance as an Influence on Positive Social Behavior in a High-Intensity Context in Middle Childhood.

Exuberance, a profile of temperament characterized in toddlerhood by high approach motivation, positive affect, and sociability, is associated with both adaptive and maladaptive socioemotional outcomes. The aims of the current study were to introduce a novel approach/avoidance-eliciting social task, as well as longitudinally extend our understanding of toddlerhood exuberance to outcomes in middle childhood. Specifically, affect and social behavior at age seven during a high-intensity game were compared to that observed during a low-intensity freeplay task. As part of a longitudinal study, 291 infants were selected at 4 months for a wide range of reactivity to novelty. The sample was assessed repeatedly across early childhood (9, 24, and 36 months of age) and at 7 years of age. A high exuberance profile was formed with approach, positive, and sociable behaviors observed in the laboratory from 4 to 36 months. At 7 years of age, affect and social behavior were assessed during high- and low-intensity interactions with an unfamiliar peer in the laboratory. Path Analyses using structural equation models demonstrated that a high exuberance profile was associated with greater positive social behavior at age 7 during a high-intensity game, but not negative social behavior or behavior during a low-intensity freeplay task. These results illuminate the need for targeted methodology, such as high-intensity approach/avoidance-eliciting social tasks, in order to clarify the links between early temperament and adaptive or maladaptive socioemotional outcomes across development.
