The current study examined the associations between the early childhood temperament of behavioral inhibition and children's displays of social problem‐solving (SPS) behavior during social exclusion. During toddlerhood (the ages of two to three), maternal report and behavioral observations of behavioral inhibition were collected. At the age of seven, children's SPS behaviors were observed during a laboratory social exclusion task based on the commonly used Cyberball game. Results showed that behavioral inhibition was positively associated with displayed social withdrawal and negatively associated with assertive behavior during the observed social exclusion task at seven years of age. These results add to our understanding of inhibited children's SPS behaviors during social exclusion and provide evidence for the associations between toddler temperament and children's social behavior during middle childhood.
