Fig. 2: Neurocognitive performance in every treatment condition.

Panel A shows mean (SE) performances at the DSST (correct substitutions), CTT (lambda-c), DAT (tracking error) and SST (commission errors) as a function of time after dosing. Panel B shows mean (SE) performance at the SMT (immediate and delayed relocation) and MFFT (impulsivity, efficiency). A * denotes a significant (p < 0.05) contrast between 3-MMC and placebo across all time points, with the color of the * representing the 3-MMC dose level.
