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.
本研究采用混合方法，旨在拓展我们对隐藏特征决策任务中群体表现背后因素的认识。我们创建了一种新的心理模拟干预措施，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。我们用主题分析对定量统计分析进行补充，以探索并更好地理解个体群体成员的动机和言论，我们认为这些对于增进对隐藏特征决策任务中个体和群体层面所面临挑战的理解至关重要。许多群体决策研究采用定量方法，寻找对群体过程中事情为何如此发生的因果解释。作为该领域的一个子集，现有的隐藏特征研究集中在定量领域。然而，定性研究可以增进对群体现象的理解，比如沟通方式，这在群体决策中很重要。据我们所知，没有隐藏特征研究采用过类似方法，因此本文做出了独特贡献。结果表明，心理模拟对隐藏特征招聘任务中的信息交流和决策质量有积极影响。
