Table 3 d’, hit rate, FA (false alarm) rate, c (response bias) and reaction time (RT) for pre- and posttest, for the two strain groups, THC and THC + CBD. Means are reported with 95% within subject confidence intervals in brackets. The right columns indicate significant differences from the t-test on group differences (*: p < .05, **: p < .01)
