In analysis the therapist is trained not to show appropriate emotional reactions to transference manifestations of patients. In group therapy he is not hidden; his minimal responses can therefore be detected by members and can provoke responses in the group. Though his emotions cannot be concealed, his behavior can be controlled, and the group gains by his example.

Transference reactions are produced more rapidly in groups because the therapist is seen, and countertransference is stronger because the situation is more real and more intense emotionally than in individual treatment. When starting, many therapists are too defensive and hostile in response to pressure of the group. In many such situations the author recommends the presence of a trained observer as a corrective.
