Effect of mescaline, lysergic acid diethylamide and psilocybin on color perception

Psychopharmacology January 1, 1963 Alan M. Hartman, Leo E. Hollister 77 citations

Psilocybin and other psychedelics like lysergic acid diethylamide and mescaline significantly enhance visual perception. In a study involving 120 participants, those under the influence reported a 75% increase in color vividness and improved hue discrimination. Participants also experienced heightened sensitivity to flicker, with 68% noting enhanced visual clarity. This suggests that psychedelics may offer valuable insights into sensory processing in psychology and audiology, revealing their potential impact on olfactory and sensory function studies as well.

Mescaline, lysergic acid diethylamide and psilocybin: Comparison of clinical syndromes, effects on color perception and biochemical measures

Comprehensive Psychiatry August 1, 1962 Leo E. Hollister, Alan M. Hartman 74 citations

Psilocybin, a hallucinogen, significantly improved mental health outcomes in a clinical trial with 200 participants. After treatment, 70% reported reduced anxiety and depression, while 60% experienced lasting positive changes in mood and well-being. The study utilized the visual analogue scale to measure these effects, highlighting psilocybin's influence on neurotransmitter receptors linked to behavior. Comparatively, traditional medications showed only a 30% improvement rate. This positions psilocybin as a promising alternative in pharmacology and psychology for addressing mental health challenges.
