The developmental stability of inhibition from 2 to 5 years.

Executive functions or cognitive self-regulatory control processes are critical for children's ability to successfully navigate their academic and social environment. In this study, we focused on the development of one critical executive function skill, that of inhibitory control. In a longitudinal study, we tested 96 children at 24, 30, 36, 50, and 60 months of age with age-appropriate measures of inhibition. We found evidence for the developmental stability of inhibitory abilities. Inhibitory control at 30 months of age was strongly related to inhibitory control at 60 months of age even when verbal IQ was partialled out. [ABSTRACT FROM AUTHOR]
