The effects of scale and information distribution on group decision-making processes and outcomes

摘要: This dissertation bridges two research streams in the group decision making research: weighted opinion stream and social scheme stream. In experiments, scale of outcome - which is thought to create differences between does not affect underlying behaviors as expected. Results indicate that models interpersonal influence can generally best explain decisions both continuous discrete settings, simple complex tasks. However, if network influences known, then (information-scarce) tasks, central tendency across settings. (information-rich) faction-based tend describe processes. Additionally, contrary expectations, information processing when set different among members.
