title: Individual differences in inhibitory control skills at three years of age.
abstract: Sixty-eight 3-year-old children participated in an investigation of inhibitory control (IC). Child IC was measured using various tasks in order to determine the impact on child performance of manipulating task demands. Performance on a nonverbal IC task, but not performance on more difficult motivational or traditional IC tasks, was explained by medial frontal electroencephalographic activity and by language abilities. Because of the unique relations of nonverbal IC with concurrent developmental measures, and because of its potential to predict later social problems, we conclude that it is important to include nonverbal IC measures in investigative IC batteries in early childhood.
