This research seeks to expand our knowledge of what underlies group performance in Hidden Profile decision tasks, adopting a mixed methods approach. We created a new mental simulation intervention designed to improve group decision outcomes and information exchange and tested it across two studies. We supplemented our quantitative statistical analysis with Thematic Analysis, to explore and better understand the motivations and utterances of individual group members, which we contend are key to increasing understanding of the challenges operating at individual and group levels in Hidden Profile decision tasks. Much group decision-making research uses quantitative methodologies, searching for causal explanations of why things happen as they do in group processes. As a subset of this area, existent Hidden Profile research is centred in the quantitative domain. Yet qualitative research can improve the understanding of group phenomena, such as communication style, which is important in groups’ decision-making. To our knowledge, no Hidden Profile research has taken a similar approach, so this paper makes a unique contribution. Results indicated the mental simulation had a positive effect on information exchange and decision quality in a Hidden Profile hiring task.

“我只是假装我能看到这些东西！”：小组成员在决策中的声音隐藏的个人资料

本研究采用混合方法，旨在扩大我们对隐藏配置文件决策任务中群体绩效的基础知识的了解。我们创建了一种新的心理模拟干预，旨在改善群体决策结果和信息交流，并在两项研究中对其进行了测试。我们用主题分析补充了我们的定量统计分析，以探索和更好地了解单个小组成员的动机和言论，我们认为这是增加对隐藏配置文件决策任务中个人和小组级别操作挑战的理解的关键。许多群体决策研究使用定量方法，寻找事物在群体过程中发生的原因的原因解释。作为该区域的一个子集，现有的 Hidden Profile 研究集中在定量领域。然而，定性研究可以提高对群体现象的理解，例如沟通方式，这对群体决策很重要。据我们所知，没有任何 Hidden Profile 研究采用类似的方法，因此本文做出了独特的贡献。结果表明，心理模拟对隐藏档案招聘任务中的信息交换和决策质量有积极影响。
