In conclusion, studying the relationship between impulsivity and alcohol use is a challenge that has been magnified by the wealth of different measures used to index a heterogeneous construct. In order to advance our understanding of how rash action is related to alcohol use/problems, we need (1) better delineation of the impulsivity construct into more homogeneous facets in the personality literature; (2) systematic efforts to relate these facets to the different aspects of impulsivity measured via different laboratory tasks; and (3) research aimed at characterizing how these different aspects of impulsivity, as measured in human questionnaires and laboratory tasks, relate to the different animal models of impulsivity.
