Abstract
A “difficult” size discrimination (ratio 1.12:1) was disrupted in four of five squirrel monkeys by 10 to 40 μg/kg LSD-25 whereas an “easy” discrimination (ratio 1.96:1) was relatively unaffected. Disruption lasted from 4–6 months postinjection in two of the monkeys. Neither the difficult nor the easy discrimination was affected in three monkeys by up to 100 μg/kg BOL-148.
