Entry behavior and emotion regulation abilities of developmentally delayed boys

This study investigated the social deficits of developmentally delayed children. Participants were 48 five-year-old to eight-year-old boys. Delayed children (n = 20) were compared with nondelayed children of similar chronological age (CA nondelayed; n = 20) and of similar mental age (n = 8). The behavior and emotion regulation strategies of participants were assessed in an analogue entry situation. Delayed children were just as able as nondelayed children to understand the play themes of others but were more intrusive in delivering their entry attempts. Delayed children appeared to have less effective emotion regulation strategies for coping with entry failure and were more likely to increase their use of disruptive entry strategies over time than CA nondelayed children.
