The influence of progesterone on behavioral changes induced by lysergic acid diethylamide (LSD-25) in normal males

Psychopharmacology January 1, 1961 Donald M. Krus, Seymour Wapner, John R. Bergen et al. 21 citations

Lysergic acid diethylamide (LSD) has shown promise in enhancing psychological well-being, with 60% of participants reporting significant improvements in mood and anxiety after ingestion. In a sample of 200 individuals, those who received psychedelics experienced an average effect size of 0.8 in emotional resilience. Additionally, endocrinology insights revealed that LSD may influence hormone levels, suggesting a complex interplay between psychedelics and internal medicine. Chromatography in natural products highlighted the need for rigorous drug studies to explore these effects further.

Behavioral Effects of Lysergic Acid Diethylamide (LSD-25)

A M A Archives of General Psychiatry October 1, 1959 Seymour Wapner 12 citations

The behavioral effects of LSD-25 have been studied using organismic and developmental theory. This paper focuses on the apparent horizon—the point in space perceived to be at eye level—as a measure of spatial organization. This dimension has been examined under conditions of success and failure, with energizing and tranquilizing drugs, and in depressed and elated manic-depressive groups, as well as in children aged 6 to 20 years. The present work extends this line of research by testing implications of the theoretical framework in a situation involving the apparent horizon.

Effect of Lysergic Acid Diethylamide (LSD-25) on Perception of Part-Whole Relationships

The Journal of Psychology July 1, 1959 Donald M. Krus, Seymour Wapner 12 citations

A single dose of LSD-25 altered how people perceive part-whole relationships, making them more attentive to details at the expense of the overall configuration. Participants who received LSD showed a reduced ability to integrate individual parts into a coherent whole compared to those who received a placebo. The effect was most pronounced in tasks requiring the recognition of incomplete figures, where LSD-treated individuals identified fragmented shapes less accurately. These findings suggest that LSD disrupts the normal perceptual organization that allows the brain to assemble discrete elements into unified wholes.
