And K100845) and We Thank Support of the Active Psychology Foundation Oxytocin and Cortisol in Hypnotic Interaction

The change in the level of oxytocin and cortisol was tested in the participants of hypnotic interaction in standardised laboratory sessions with healthy volunteers. Pre to posthypnosis changes of oxitocin and cortisol were related to the hypnotic susceptibility of Ss, and to relational experiences reposted by subjects and hypnotists on several paper and pencil tests (AIM, DIH, s-EMBU). Results show that the changes in oxytocin are not related to the hypnotic susceptibility, but to the relational experiences. After the hypnotic interaction, the level of oxytocin increases in the subject if the perceived harmony with the hypnotist is high (DIH), while it increases in the hypnotist if the subject has memories of less warm emotional relationship with his/her parents (s-EMBU). The results are interpreted within the social psychobiological model of hypnosis.
