| Abstract: | Inhibitory control is the capacity to suppress inappropriate responses. It is central to many aspects of development, most notably executive function and effortful control. Despite its importance, however, there are significant gaps in our understanding of inhibitory control’s early development, and several findings that remain hard to explain. Here, a new account of inhibitory control is presented, explaining previous findings by distinguishing between two distinct ways that inhibitory control is used. According to this “Strength/Endurance” account, inappropriate responses which are highly prepotent tax inhibitory strength; whereas inappropriate responses which remain active for a long time tax inhibitory endurance. The developmental trajectories of these two aspects of inhibitory control, and their separate impacts on broader development, are discussed. |
