The recent revolution in psychology has readmitted cognition and consciousness as legitimate areas of scientific investigation. The study of cognitive processes has made rapid strides by taking as its model brain mechanisms assumed to be similar to those of the digital computer (Miller, Galanter, and Pribram, 1960) and by utilizing reaction- time data investigations of memory for verbally coded materials. The currently projected volumes on consciousness and self-regulation presuppose that equally effective strides can be made in our research on, and understanding of, consciousness. The title of the series, in fact, suggests that data on self-regulation, utilizing biofeedback procedures, will provide the substance upon which such strides will be based.
