Notes:
Lang and Hnatiow, who derived a measure of heart rate (HR) response different from that employed by Dykman, Reese, Galbrecht, and Thomasson, reported better evidence of HR adaptation to serially presented tones than did Dykman et al. The former authors found no habituation when Dykman's procedure for scoring HR responses was applied to their data. When Dykman's HR records were rescored by Lang's method, both measures yielded adaptation curves.McDonald, Johnson, and Hord, who employed a measure of HR response similar to that of Lang and Hnatiow, noted that alert Ss adapted in HR, while drowsy (by electroencephalogram (EEG) activity) Ss failed to adapt. They said that HR adaptation results of Dykman et al. may have been influenced by inadequate control for arousal level of Ss. However, the most drowsy Ss (judged by behavioral notes) in Dykman's study provided good evidence of HR adaptation by both McDonald's and Dykman's measures.These discrepancies in results are believed to depend mainly upon differences in experimental procedures rather than upon methods of scoring or arousal level.
