Abstract
The results on the Halstead-Reitan neuropsychological battery were compared for a group of 20 LSD users and a normal control group matched for age, sex, education, and intelligence. Only one of 20 variables was significantly different at the 5 per cent level and this was thought to be due to chance. Thus, it was concluded that there was no difference between the two groups. A further comparison between LSD users and university students yielded no significant difference in the Halstead-Wepman Aphasia Test.
