A beat‐by‐beat analysis of the human heart rate (HR) response to repeated presentation of 3 intensities of auditory stimulation (50, 70, and 90 db) was undertaken to test the hypothesis that the HR component of the orienting response (OR) is deceleration. Over‐all level of poststimulus acceleration and a late acceleratory component of a multi‐phasic response pattern best met the criteria of an OR, suggesting an alternative hypothesis.
