Outcomes of temperamental inhibition in young children are moderated by attentional biases

The current longitudinal study examined the association of temperamental inhibition (assessed by behavioral observation and parental reports) at three years old with reward and punishment bias (measured by a spatial cueing task) and mothers’ and teachers’ reports of internalizing behaviors and social competence at five years old in 153 Chinese children. As predicted, behavioral inhibition positively predicted later mother-rated internalizing behaviors. In addition, punishment bias moderated this relation such that children with higher punishment bias showed a positive inhibition–internalizing link. Furthermore, inhibition negatively predicted both mother-rated and teacher-rated social competence. However, novel findings were that reward bias moderated the relation between inhibition and teacher-rated social competence, such that inhibited children showed an increased risk of low competence when they had lower reward bias.
