By the 1970s psychology had made sizable advances with its primary emphasis on the study of overt behavior, but its progress on covert behavior had been delayed because of the lack of suitable psychophysiological technology. Originally published in 1979, this title was written to help laboratory researchers in their efforts to develop a mature science of covert behavior. Early efforts to record small-scale behavior with flattened wine glasses about the tongue were heroic, but understandably progress did not begin until the advent of very sensitive electronic equipment. In 1979 we were now technologically capable of: (1) sensing; (2) amplifying; (3) recording; and (4) quantifying small-scale behavior with at least the effectiveness with which we have studied large-scale responses. It was hoped that this book would facilitate the empirical efforts of future psychophysiologists and professional researchers in each of these four phases of the laboratory system. More generally it was hoped that it would serve as an important component in our efforts to understand behavior. Today it can be read in its historical context.

The Psychophysiology of Thinking: Studies of Covert Processes describes the relation between brain events and peripheral bodily phenomena in the context of psychological theory. This book is organized into six parts encompassing 14 chapters, which focus on higher mental processes. This book starts with the historical development of electrical measures of covert processes. The subsequent chapters discuss the mechanism of conditioning of central nervous system, the skeletal musculature, and the autonomic activity. Other chapters explore the principles of hallucinations, sleep and dreaming, imagery, biofeedback, evoked potentials during thought, meaning, and thought with concomitant measures. The remaining chapters emphasize cerebral mechanisms, which principal concern is with the involvement of other bodily mechanisms in thought. Psychophysiologists, neurobiologists, behaviorists, and researchers in the fields of thinking and covert processes will find this book invaluable.
