This is a precis of a book on frustration theory, whose explanatory domain includes a family of phenom~na that have been summarized by the terms dispositional learning and memory-systems that ordmarily have a long-term historical etiology, and in which the learning is relatively reflexive and the memo~implicit and not strongly episodic. The book is an attempt, in the context of stimulusre~ponse l~a~mng theOI'~' to present in some detail an animal-based model of frustration as it is appIled to a Ilmlted-but stIll large-number of these experimentally established phenomena (perhaps the largest number organized by anyone such theory). These bear some resemblance to equivalent phen~mena in humans, to which the descriptive terms arousal, suppression, persistence, and regre~sIOn have been applied. An explicit caveat is that this is a book on one particular theory of frustratIOn and not a book on frustration theories. Whereas it does address other theories of frustration its main purpose is to review a line of theorizing and experimental research that has evolved ove; some 40 years: an analysis of the status of the concept of frustration in learning theory.In the history of the scientific study of learning and memory, a number of terms have been used to describe abstract experimental paradigms that purport to represent different mechanisms of learning. In the book discussed here, I refer to several of these, the most fundamental being classical (Pavlovian) conditioning and instrumental (Thorndikian) learning. These two are central to understanding the phenomena I will call the rewardschedule effects. These phenomena depend on a variety of interactions between reward and nonreward, and they are the basis for a family of generalizations known as frustration theory.My major thesis, in general terms, is that there is inherent in such reward schedules the buildup of primary frustration, defined simply as a temporary state that results when a response is nonreinforced (or nonrewarded, in more neutral language, in the appetitive case) in the presence of a reward expectancy; that a learned or anticipatory form of this temporally labile state, based on classical conditioning, can be elicited by an originally indifferent or neutral cue; that this conditional form of frustration, like other learned states, is permanent, at least for a given situation; and that, together, the primary (unlearned) and the secondary (learned) forms can account for a number of important processes in the dynamics of instrumental behavior, summarized by four familiar behavioral concepts: arousal, suppression, persistence, and regression. These four concepts define I am greatly indebted to Elizabeth Capaldi and Michael Rashotte for their valuable suggestions for revision of an earlier draft of this precis.
