Summary
AI-generated from the abstractPeople have a natural tendency to misjudge the position of the visual vertical relative to the gravitational vertical. A 160 µg/kg dose of psilocybin accentuated this misjudgment in 16 college-age volunteers. The drug-induced accentuation was further augmented after exposure to strong body distortion.

Abstract
There is a “natural” tendency to misjudge the position of the visual as compared to the gravitational vertical. A 160 µg/kg psilocybin-induced accentuation of this misjudgment in 16 college-age volunteers, and a further augmentation in their accentuated drug response after exposure to strong body distortion is reported.
