The adult male monkeys (macaca fuscata fuscata) were used in this study. After ecological behavioral observations on three selected pairs, bilateral temporal lobes of the dominant monkeys were removed and submissive ones were operated with only exploratory craniotomy for the control study. Subsequently, the behavioral changes were observed individually and in the each same pair. Individual behavioral changes of the bilateral temporal lobectomized monkeys were those of the Klüver-Bucy's syndrome. Changes in pair suggested the "socioagnostic" behavior. Selected one of the operated dominant monkeys with persistent Klüver-Bucy's syndrome, psychometric examinations mediated visually, were performed to elucidate the mechanism of the agnostic behaviors which were observed ecologically, which was the main purpose of this study. The various visual discriminations (of color, form, size and brightness) were tasked on the bilateral temporal lobectomized monkey under proper conditionings with comparison to the sham· operated monkey as the control monkey. Eventually, the bilateral temporal lobectomized monkey could not learn the tasks after even 200 trials each, while the control monkey was able to reach to the criterion (20 consecutive correct responses) finally. The essential factor of the agnostic behaviors seem to be settled on the dissociation of the limbic function from the visual function.
