抄録

An experiment in inter-cultural innovation was administered to 60 French subjects. Slide-color-judgment task was given to 12 subject group comprising of 5 French subjects each, under the condition where a Japanese collaborator, introduced as a subject, was placed in each group to provide the answer "green" at the sight of a blue slide. The Japanese collaborator, based on his having a foreign nationality, being alone in totally French subject group and providing a deviant answer, is defined as an outgroup minority in the subject group, and following hypotheses were tested and found valid: 1) The influence of the outgroup minority upon the group is caused only during his absence. 2) A conversion phenomenon in the perception level of cognition occurs when the deviant response of the outgroup minority is socially categorized as a minority response in Japan. 3) Influence at the manifest level occur when there is no social categorization process.
