Another strategy that has suggested a genetic correlation between impulsivity and alcohol use is to correlate these measures across inbred strains. For example, Logue, Swartz & Wehner (1998) found that the ability to withhold nosepoking until signaled, which they used as ‘a measure of behavioral control or impulsivity’, was negatively correlated with ethanol consumption across 13 inbred mouse strains. Strains that were better able to control their behavioral responding (i.e. less impulsive) consumed less ethanol and vice versa.
