This is a course in Psychology, Social Psychology and Sociology. It examines factors that produce and influence behaviour, particularly in workplace settings. It is a theoretical course that is at the same time concerned with practice and research. "Applied”, in the title of the course, emphasizes, for HRD, that theories and research studies should be investigated for their relevance to improvements in everyday work life. "Behavioural” refers to the general domain of study - human behaviour, including individual, interpersonal and group levels of analysis. The "Science” component must be emphasized as well, given that we seek to ground interventions in knowledge that is gathered through the scientific method. By situating work life in the context of larger social systems, the course offers the opportunity to appreciate Caribbean realities of social structure, history and culture
