Communication in small groups : ウィキペディア英語版 | Communication in small groups Communication in small groups is interpersonal communication within groups of between 3 and 20 individuals. Groups generally work in a context that is both relational and social. Quality communication such as helping behaviors and information-sharing causes groups to be superior to the average individual in terms of the quality of decisions and effectiveness of decisions made or actions taken. However, quality decision-making requires that members both identify with the group and have an attitude of commitment to participation in interaction. == Group communication == The first important research study of small group communication was performed in front of a live studio audience in Hollywood California by social psychologist Robert Bales and published in a series of books and articles in the early and mid 1950s .〔Bales, R. F. (1950). ''Interaction process analysis''. Page 33. Cambridge, MA: Addison-Wesley.〕〔Bales, R. F. (1950). ''Interaction process analysis''. Cambridge, MA: Addison-Wesley.〕〔Bales, R. F., and Strodtbeck, F. L. (1951). Phases in group problem-solving. ''Journal of Abnormal and Social Psychology, 46,'' 485-495.〕 This research entailed the content analysis of discussions within groups making decisions about "human relations" problems (i.e., vignettes about relationship difficulties within families or organizations). Bales made a series of important discoveries. First, group discussion tends to shift back and forth relatively quickly between the discussion of the group task and discussion relevant to the relationship among the members. He believed that this shifting was the product of an implicit attempt to balance the demands of task completion and group cohesion, under the presumption that conflict generated during task discussion causes stress among members, which must be released through positive relational talk. Second, task group discussion shifts from an emphasis on opinion exchange, through an attentiveness to values underlying the decision, to making the decision. This implication that group discussion goes through the same series of stages in the same order for any decision-making group is known as the ''linear phase model''. Third, the most talkative member of a group tends to make between 40 and 50 percent of the comments and the second most talkative member between 25 and 30, no matter the size of the group. As a consequence, large groups tend to be dominated by one or two members to the detriment of the others.
