Young children's difficulty with inhibitory control in a social context1

Abstract: The authors’ prior research has documented that young children's behaviors in the Dimensional Change Card Sorting (DCCS) task can be influenced by their observation of another person performing the task and has suggested that young children committed perseverative errors in a social context. The present study explored whether children who committed perseverative errors in the social context also committed perseverative errors in the standard DCCS task. Three‐ and 4‐year‐old children were given the standard DCCS and the observation version of the DCCS, and the relationship between them was examined. The results showed that the correlation between these two tasks was significant. Furthermore, 4‐year‐old children displayed more difficulty in the observation version than in the standard DCCS, whereas 3‐year‐olds did not. The results are discussed in terms of the development of inhibitory control and social cognition.
