preference. An additional analysis was performed to assess whether there was any correlation between trials completed and k values, our central measure of impulsivity. We ascertained this correlation by determining the mean number of trials completed by each mouse from both experiments, and correlating it with that mouse’s lnk value. Across all 68 mice included in the study, this correlation (Pearson’s) was r = 0.219, p = 0.073.
