Each of these eight units dealing with human behavior is designed for high school psychology courses and consists of a teacher handbook and a student booklet. The developers believe that the systematic study of behavior can increase students' understanding of the lives they lead. Each unit was prepared by a different team consisting of two high school teachers, a varying number of high school students, and a specialist in the science of human behavior. The unit themes, chosen both for their interest to students and for the basic understandings of human behavior they provide, can be studied independently or they may be used together to form a course of nearly any length from three weeks to a year. The units are: Natural Behavior in Humans and Animals, States of Consciousness, School Life and Organizational Psychology, Social Influences on Behavior, Changing Attitudes, Conditioning and Learning, Language and Communication, and Studying Personality. The teacher handbook for each unit summarizes the unit, describes unit goals, provides detailed teaching instructions for each of the unit's lessons, suggests activities, cites additional resources for classroom use, and contains duplicating masters. The student booklet consists of readings. Students are expected to read and discuss the selections and actively participate in many classroom activities. For example, activities involve students in analyzing psychological studies, interpreting data, listening to recorded speech samples and analyzing them, giving and listening to reports of observations of natural behaviors, and reading a brief case study.
