change was most pronounced during high-dose ethanol administration (Figure 2). In a model to assess change between the +30 and +60 timepoints, also paralleling the simulant results, the dose by impulsivity interaction was significant (num df = 1.99, ATS = 7.25, p = 0.001), but the three-way interaction was not (num df = 1.99, ATS = 0.13, p = 0.874). This meant that the less impulsive participants were, the stronger their sedative response, particularly in the high dose condition, but that this relationship applied in the same way across the +30 and +60 timepoints, thus the lack of a significant three-way interaction.
