The present research reports correlations between ratings of distractibility and minor physical anomalies and gross motor incoordination. For an original and two replication samples of preschool children, there were significant average weighted correlations between distractibility and both minor physical anomalies and gross motor incoordination for boys. Also, the magnitude of the correlation between distractibility and the congenital characteristics was significantly higher for boys. Although neither parental rejection nor parental restrictiveness was related to boys' distractibility, parental rejection was marginally related to girls' distractibility.
