Abstract
The author observed an alteration of behavior in a 37 years-old, male patient with schizophrenia. Though the patient had not severe disturbance of thought, he neglected taking medicines in spite of every psychotherapeutic effort of the medical staff. Then, the staff made all of the other patients of his room taken medicines in the room at the same time. 3 weeks after the continuous managements, the patient came to take medicines of himself.
The considerations to this case were as follows:
1) The patient recognized the other patients belonging to a group when he saw they took medicines in the room at the same time. 2) He came to take medicines, because he wanted to take part in the group. 3) Presentation of a complete conduct produces recognition of a group, and belonging to a group is preferred. These will be general and fundamental points even in us.
