Perceptions of Cooperation in a Longitudinal Social Dilemma

Most social dilemma studies of communication’s effects on cooperation are based on laboratory results with trivial incentives. Studies of real-life social dilemmas with nontrivial rewards are needed to extend the generality of laboratory results. Perceptions of cooperation on a group product (weekly group essay) were examined as a public goods dilemma embedded in a longitudinal study of groups using either face-to-face or computer-mediated communication. Perceptions of cooperation increased over time, whereas measures of group identity did not. No media effect on perceptions of cooperation was observed. Several predictors of late perceptions of cooperation were examined, but only early perception of cooperation was significant. Results are discussed with respect to several current hypotheses regarding communication and cooperation in social dilemmas.Yeshttps://us.sagepub.com/en-us/nam/manuscript-submission-guideline

A Tripartite Model of Group Identification: Theory and Measurement

Group identification is defined as member identification with an interacting group and is distinguished conceptually from social identity, cohesion, and common fate. Group identification is proposed to have three sources: cognitive (social categorization), affective (interpersonal attraction), and behavioral (interdependence). Inconsistent use of the term and problematic measurement mar existing literature on group identity and group identification. A new group identification scale, composed of three subscales that match the tripartite model for the cognitive, affective, and behavioral sources, is presented and its psychometric properties described.Yeshttps://us.sagepub.com/en-us/nam/manuscript-submission-guideline

Attitude Change in Inductively and Deductively Organized Ethical Belief Structures

145 p.Thesis (Ph.D.)--University of Illinois at Urbana-Champaign, 1997.Two experiments were conducted to examine ethical belief structure regarding the issues of abortion and euthanasia, and to explore the effects of structure on attitude change. The first experiment explored these issues from a pro-life perspective and the second experiment from a pro-choice perspective. Deductive and inductive logic were proposed as ways to organize beliefs in these domains. Participants rated agreement with the behavior of the protagonist in four abortion and four euthanasia scenarios where the principle of respect for life (Experiment 1) or choice (Experiment 2) was violated. Following the ratings of the scenario, a persuasive message that was either concrete or abstract in its argument targeted one of the eight scenarios. Participants then rerated agreement with the protagonist in the scenarios. Attitude change occurred in scenarios that were targeted by a persuasive message as well as in nontargeted scenarios. Deductive belief structure was shown to play a larger role in producing transfer effects of the persuasive message to nontargeted scenarios than inductive belief structure. The structure of deductive and inductive organization of beliefs depended on the perspective of the experiment--pro-life versus pro-choice. The type of persuasive message used was not a limitation to the transfer effect, but the nature of the ethical principle being targeted was.U of I OnlyRestricted to the U of I community idenfinitely during batch ingest of legacy ETD
