Abstract
The modifications of human vocal fundamental frequency (fa) were studied in six emotional imitations of a sequence during normal and hypnotic conditions. In hypnosis the fundamental frequency was significantly lower than in the normal condition; in particular, in this altered state of consciousness two emotional imitations (angry and crying conditions) were significantly different with respect to the normal condition.
