In this report, I examined the influence of Dohsa Method's application in the psychological rehabilitation camp on a trainee's lobbying for others. This trainee had a weak point for exchanges with others, exhibited delayed intellectual development, and tended to be tense toward others. At the beginning, he did not respond positively when others approached him. However, during the training, he demanded reaction from the trainer at numerous occasions, which made me think that his lobbying for others has changed. Therefore, I aimed to devise a method to determine the relation between the trainee's lobbying and Dohsa Method's application. Consequently, a pattern of exchanges was found. In such a relation, "the joint ownership of the place" led to "affective joint ownership" after "the joint ownership of the movement." According to me, the application did influence his training.
