Conflict duration on the flanker task (i.e., reaction time for each incongruent trial–reaction time for each congruent trial) pre- (white bar) and post-treatment (black bar) with OT or placebo.

<p>Two-way ANOVA (treatment × drug) failed to demonstrate any drug or treatment effects, and no significant interaction between these two factors was detected. Therefore, we failed to demonstrate any OT-related effect on attentional-inhibitory control. The error bars represent 1 standard error.
