Abstract

Over a 4-mo period we conducted 57 training sessions totaling 26.5 h of training. .. In the first 5 training sessions, 76% of the monkeys cooperated with the request to move; during the last 5 sessions, 86% cooperated, indicating some progress but still falling short of what was intended.
