With respect to the second study question, we found that behavioral disinhibition in both early (age 12) and late (age 17) adolescence was significantly related to response inhibition at age 17 (rs = −.44 at age 12 and −.41 at age 17). Moreover, behavioral disinhibition at each age was significantly more closely associated with response inhibition than with the two other executive functions (working memory updating and task-set shifting) measured at age 17. These results support the hypothesis that behavioral disinhibition does indeed share something in common with cognitive response inhibition.
