The purpose of the study was to test nine hypotheses derived from the theory of E. N. Sokolov. The hypotheses tested dealt with the habituation and return of the orienting response, and with the relationship between the orienting and adaptive responses. Three presentations of an auditory stimulus were interpolated among a series of 28 presentations of a cold stimulus administered to one group of 13 human subjects and among 28 presentations of a hot stimulus administered to another group of 13 subjects. Heart rate and amplitude and latency of vasomotor response to all stimuli were measured using a finger photoplethysmograph. When vasoconstrictive orienting responses to hot and to cold habituated out, vasoconstrictive adaptive responses to cold and vasodilatory adaptive responses to heat appeared. Eight of the nine hypotheses were confirmed, thereby providing strong support for Sokolov's theory, upon which the hypotheses were based.
