This work provides a tutorial introduction to behavioural applications of control theory. Control theory describes the information one should be sensitive to and the pattern of influence that one should exert on a dynamic system in order to achieve some goal. As such, it is applicable to various forms of dynamic behaviour. The text primarily deals with manual control, both as a substantive area of study and as a useful perspective for approaching control theory. It is the experience of the authors that by imagining themselves as part of a manual control system, students are better able to learn numerous concepts in this field. Topics include varieties of control theory, such as classical, optimal, fuzzy, adaptive, and learning control, as well as perception and decision making in dynamic concepts. The authors also discuss some of the implications of control theory for how experiments can be conducted in the behavioural sciences.
