This suggestive power plays of course a specially prominent part in dealing with disorders of a directly psychopathic nature[142] and peculiarly so where a condition of enhanced suggestibility is deliberately induced and utilised with a view to the cure of such disorders, as in the practice of hypnotism. The work which has been directed to the study of hypnotism from the psycho-analytic point of view has brought out very clearly the similarities between the condition in hypnosis and some of the mental characteristics of early childhood; and has led to the conception of the hypnotic trance as a regression to a relatively infantile state of mind, the _rapport_ between operator and subject being regarded as, in certain important respects, a repetition or revival of the relations which had previously existed between parent and child. Ferenczi[143] has gone so far as to regard the different methods of inducing hypnosis as depending upon a revival in a displaced form of the child's typical attitude towards its father or its mother respectively; the stern, commanding, confident tone, adopted by some operators, tending to bring about a relationship between them and their subjects that constitutes a revival of the former relationship between father and child, the calming, soothing, soporific methods of others serving to recall the attitude of the child towards its mother, as when in early infancy it was lulled to sleep by its mother with the aid of a very similar procedure.
