Understanding early inhibitory development: distinguishing two ways that children use inhibitory control

Inhibitory control is the capacity to suppress inappropriate responses. It is regarded as a unitary construct, central to executive function and effortful control, as well as many aspects of child development. There are, nevertheless, significant gaps in our understanding of inhibition’s early development, and several robust findings that remain hard to explain. These findings are outlined, and a new perspective on inhibitory control presented, which explains them by distinguishing between two ways that inhibitory control is used. According to the ‘strength/endurance account’, responses which are highly prepotent tax inhibitory strength; whereas, those which remain active for a long time tax inhibitory endurance. The review considers when and how these aspects of inhibition mature, before discussing their impact on development
