The Perception of Stimulus Relations: Discrimination Learning and Transposition focuses on the processes, methodologies, and approaches involved in discrimination learning and transposition. The book first offers information on stimulus equivalence, transposition of paradigms, and the transposition and relation perception problems. The manuscript then examines measurement, training, subject, and test variables. Topics include stimulus and procedural variables, effect of direction of transposition test, phylogenetic comparisons, concept knowledge, and speed of original learning. The publication elaborates on form transposition, including transposition of visual forms and the meaning of form and form transposition. The text then takes a look at relational and absolute theories, summary of findings and evaluation of theories, and outline of a theory of transposition. Discussions focus on assumptions and basic deductions, effect of absolute stimulus components, effect of noticing change in stimuli from training to test, and stimulus similarity. The book is a valuable source of data for readers interested in discrimination learning and transposition.

Scientific work on mnemonics and imagery conducted in the 1960s and early 1970s was directed at testing enthusiastic claims of the efficacy of memory tech niques developed by the ancient Greeks and further refined in the popular litera ture by "professional" mnemonists. The early research on imagery and mnemonics confirmed many of these claims and also illuminated the limitations of some techniques (e. g. , bizarre imagery). As such, these seminal studies clearly were valuable in providing a solid data base and, perhaps as important, making imagery and mnemonics acceptable research areas for experimental psycholo gists and educators. After this initial surge of work, however, it seemed that sub sequent contributions met with the attitude that "mnemonic techniques and imagery help memory, what else is new?" This attitude was not completely justi fied, however, given the theoretical insights from the work of such imagery and mnemonics pioneers as Gorden Bower, Allan Paivio, and William Rohwer. In the 1980s this claim is completely unjustified. Research on mnemonics and imagery has grown in exciting ways. Researchers are tapping the area's theoretical potential, both in terms of extending basic memory theories to account for the robust effects produced by mnemonic techniques and in terms of using explanations of mnemonic effects to understand basic memory processes. Individual differences in the use of imagery and mnemonic encoding activities are also being explored. This research has provided valuable information for basic memory theories (e. g.

First published in 1978. In this book the author has attempted to present a systematic theoretical and factual account of the role of higher mental processes in human learning and memory, and certain aspects of the psychology of perception and language. The major orienting theme of the book is its dual emphasis on nonverbal imagery and verbal processes (inner speech) as memory codes and mediators of behavior. Based on recent experimental evidence, the conceptual approach in a sense represents an integration of pre-behavioristic and behavioristic views concerning the nature of thought. The book is intended both as a textbook and as a theoretical monograph.
