Psilocybin Slows Down Human Reaction Times and Impairs Executive Function During the Acute Phase of Use
Researchers conducted a systematic review and multilevel meta‑analysis of 13 studies, finding that psilocybin dose‑dependently slows reaction times during its acute phase. While low to medium doses cause mild delays, high doses produce moderate to severe slowing, especially in basic attention tasks. Accuracy is only marginally affected and not statistically significant. The uniform cognitive slowing across executive functions underscores the need for supervised clinical settings when using psilocybin therapeutically.
