Description: This 1974 Frederick Wiseman film presents daily activities at the Yerkes Primate Research Center. Scientists in this 105-minute documentary are seen studying the physical and mental development of primates through experiments dealing with the behavioral effects of drugs and alcohol; the capacity to learn, remember, and apply language and manual skills; control of aggressive and sexual behavior; and other neural and physiological determinants of behavior.~ Bhob Stewart, All Movie Guide
