Figure 2.
Schematic of the partially differentiable constructs of impulsivity, disinhibition, and risk-taking. Some behaviors represent inhibition as well as impulsivity, but other impulsive behaviors include processes beyond response disinhibition, and some disinhibitory problems are not impulsive in the usual sense of the word (e.g., ruminative obsession). Risk taking can be impulsive, or not.
