What this means for my practice?

Psilocybin impairs multiple-object tracking (attention), but not spatial working memory. A previous correlation between performance on attentional tracking and spatial working memory tasks that was present in the placebo condition was eliminated under psilocybin. These findings indicate that psilocybin induces a functional dissociation between attention and working memory processes. The finding that ketanserin did not block the impairment effect on multiple-object tracking suggests that 5-HT2A receptors do not play a direct role in attentional processes, and instead provides evidence for the role of 5-HT1A receptors. These results are limited by the small sample size, and that some participants had prior psilocybin experience.
