MONKEY.REC. Twenty-three monkeys are randomly assigned to one of four groups. Group 1 gets a preparation of Monkey tonic, Group 2 gets a course in Applied Monkey Training (ATM, patent pending), Group 3 gets a course in advanced antics, and Group 4 gets a sham treatment. Each Monkey's Intelligence Quotient (MIQ) is recorded at the beginning of the study (BASELINE) and after 12 weeks after treatment (WEEK12). Data are:
