It is agreed that efforts must be made to facilitate the candidate in developing his own individual style of therapy. It is on how to implement the principles that the divergences in training practice arise. On the one hand, it is held that the most important feature of the training analysis is the fostering and investigation of the transference neurosis and that for this to be accomplished one analyst is best. On the other hand, it is held that the future therapist's individuality is best served by insisting on the candidate going to two or more therapists, of whom two must be of opposite sexes. These divergent approaches to training each attempt to deal with the tendency of candidates to identify themselves with their analysts when treating patients. The introduction of another person—the supervisor—into the candidate's training means that somebody besides his analyst will from time to time come into relation with his affective life.
