Free recalls of subjective experiences were audio-recorded in 27 participants after five pseudo-randomized experimental sessions: ordinary conscious resting state, with auditory stimulation and with an imaginary mental task, as well as during AICT with and without auditory stimulation.

This article explores the theme of presence of the psychotherapist, a concept that has been of particular interest in humanistic and existential approaches. Presence was first associated with the humanistic attitudes of the practitioner and the way he or she embodies these attitudes in the here and now of the encounter. Since the publication in 2002 of Geller and Greenberg's model of therapeutic presence, several quantitative studies have explored the relationship between the therapist's perception of presence and other dimensions of the therapeutic process.

After further controversies, the definition of hypnosis is to be at the same time a modified state of consciousness and a particular intersubjective relation between a practitioner and his patient. In a synthetic way, we can say that mechanisms of hypnosis on acute pain are now well known, and its efficiency is particularly proved in the pain provoked by the care.

The development of studies on neuroimaging applied to hypnosis and to the study of pain not only helps to validate the existence of a hypnotic state but also to ratify its therapeutic effects.
