Table 3.
Reaction times by group and tap condition.
| Stimulus condition | MDMA mean (S.D.) | Non-MDMA mean (S.D.) | Effect size | pa |
|---|---|---|---|---|
| Tap 1 | 523.07 (63.93) | 498.91 (67.22) | 0.36 | 0.381 |
| Tap 2 | 706.09 (71.53) | 671.02 (59.08) | 0.49 | 0.217 |
| Tap 4 | 773.76 (33.37) | 768.19 (31.66) | 0.17 | 0.685 |
Analysis of stimulus condition by MDMA group indicated a statistically significant linear effect of tap condition (p < 0.001), however no statistically significant difference in that linear pattern with MDMA use (p = 0.644) (multivariate mixed-effects analysis of variance).

Post-hoc univariate tests of MDMA group differences within each stimulus condition (independent T-test).
