In criminology, psychology, and sociology, the contact hypothesis has been described as one of the best ways to improve relations among groups that are experiencing conflict.〔Brown, R., & Hewstone, M. (2005). An integrative theory of intergroup contact. In M. P. Zanna (Ed.), Advances in experimental social psychology (Vol. 37,pp. 255–343). San Diego, CA: Elsevier Academic Press.〕〔Wright, S. C. (2009). Cross-group contact effects. In S. Otten, T. Kessler & K. Sassenberg (Eds.), Intergroup relations: The role of emotion and motivation (pp. 262–283). New York, NY: Psychology Press.〕 Gordon W. Allport (1954) is often credited with the development of the contact hypothesis, also known as Intergroup Contact Theory. The premise of Allport's theory states that under appropriate conditions interpersonal contact is one of the most effective ways to reduce prejudice between majority and minority group members.〔Allport, G. W. (1954). The nature of prejudice. Cambridge, MA: Perseus Books〕 If one has the opportunity to communicate with others, they are able to understand and appreciate different points of views involving their way of life. As a result of new appreciation and understanding, prejudice should diminish.〔Whitley, B.E., & Kite, M.E. (2010). The Psychology of Prejudice and Discrimination. Belmont, CA: Wadsworth.〕 Issues of stereotyping, prejudice, and discrimination are commonly occurring issues between rival groups. Allport's proposal was that properly managed contact between the groups should reduce these problems and lead to better interactions. Contact fails to cure conflict when contact situations create anxiety for those who take part. Contact situations need to be long enough to allow this anxiety to decrease and for the members of the conflicting groups to feel comfortable with one another. Additionally if the members of the two groups use this contact situation to trade insults, argue with each other, resort to physical violence, and discriminate against each other, then contact should not be expected to reduce conflict between groups. To obtain beneficial effects, the situation must include positive contact. Some of the criteria are as follows: * Equal status. Both groups must engage equally in the relationship. Members of the group should have similar backgrounds, qualities, and characteristics. Differences in academic backgrounds, wealth, skill, or experiences should be minimized if these qualities will influence perceptions of prestige and rank in the group.〔Forsyth, D. R. (2009). ''Group dynamics'' (5th ed.). Pacific Grove, CA: Brooks/Cole.〕 * Common goals. Both groups must work on a problem/task and share this as a common goal, sometimes called a ''superordinate goal'', a goal that can only be attained if the members of two or more groups work together by pooling their efforts and resources. * Intergroup cooperation. Both groups must work together for their common goals without competition. Groups need to work together in the pursuit of common goals.〔 * Support of authorities, law or customs. Both groups must acknowledge some authority that supports the contact and interactions between the groups. The contact should encourage friendly, helpful, egalitarian attitudes and condemn ingroup-outgroup comparisons. *Personal interaction. The contact situation needs to involve informal, personal interaction with outgroup members. Members of the conflicting groups need to mingle with one another. Without this criterion they learn very little about each other and cross-group friendships do not occur. The reduction of prejudice through intergroup contact is best explained as the ''reconceptualization of group categories''. Gordon Allport (1954) claims that prejudice is a direct result of generalizations and oversimplifications made about an entire group of people based on incomplete or mistaken information. The basic rationale is that prejudice may be reduced as one learns more about a category of people.〔 Rothbart and John (1985) describe belief change through contact as "an example of the general cognitive process by which attributes of category members modify category attributes" (p. 82). An individual's beliefs can be modified by that person coming into contact with a culturally distinct category member and subsequently modifying or elaborating the beliefs about the category as a whole. ==History== While Gordon W. Allport is often credited with the development of the contact hypothesis, the idea that interpersonal contact could improve intergroup relations was not a novel one. For example, in the late 1940s, sociologist, R. M. Williams, described interpersonal collaboration with goal interdependence as a worthwhile strategy to reduce intergroup hostility.〔Williams, R. M. Jr. (1947). The reduction of intergroup tensions. New York, NY: Social Science Research Council〕 Most research on the contact hypothesis resulted from World War II. Due to a shortage of combat troops, General Dwight D. Eisenhower allowed Black soldiers assigned in Europe at that time the option to volunteer for combat duty. The Army was concerned with the troop morale involving White soldiers who would possibly share the battlefield or be integrated into platoons with the Black soldiers. The results of a survey at that time were very polarized. Sixty-two percent of segregated units involving White soldiers said they would dislike the idea of serving in semi-integrated units. White soldiers who were currently serving within semi-integrated units reported only 7% dissatisfaction. This supports the notion that intergroup contact, under the right conditions, can reduce prejudice. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「contact hypothesis」の詳細全文を読む スポンサード リンク
