Abstract
The present study investigated the effects of Ginkgo biloba on verbal memory, spatial memory, simple reaction time, choice reaction time, and mood. Pretest and posttest measures of memory and reaction time were assessed using the Stim2 computer software designed by Neuroscan. Pretest and Posttest measures of mood were assessed using the Visual Analog Mood Scales (VAMS). Following the pretest measure, participants received one of three treatments: placebo, 120mg Ginkgo biloba, or 360mg Ginkgo biloba. Posttest measures were taken 2.5 hours after administration of treatment. Statistical analyses showed no significant differences between any of the three treatments in terms of cognitive performance or mood. Implications of the study’s findings are discussed.
