先前的研究表明，两个人一起工作可以胜过一个人单独工作，但这种好处是来自社会互动还是来自独立反应的统计促进，目前尚不清楚。在这里，我们应用米勒的（认知心理学，14，247-279，1982;乌尔里希，米勒和施罗德，行为研究方法，39（2），291-302，2007）种族模型不等式（RMI）来区分这两种可能性。成对的参与者完成了视觉枚举任务，既作为独立的个人，也作为一个团队的两名成员。结果表明，团队绩效超过了两个人独立工作的效率，表明人际互动的基础上，在这项任务中的合作收益。这种解释得到了支持的分析表明，积极介导的社会联系的力量和团队成员之间的口头沟通的相似性的合作效益的大小。这项研究提供了概念验证，证明米勒的RMI可以区分协作认知的互动效应和独立效应。此外，社会关系和通信相似性的发现，每个有助于合作的好处，建立支持协作认知的机制，提出了新的研究途径。
Previous research has shown that two heads working together can outperform one working alone, but whether such benefits result from social interaction or from the statistical facilitation of independent responses is not clear. Here we apply Miller's (Cognitive Psychology, 14, 247-279, 1982; Ulrich, Miller & Schroter, Behavior Research Methods, 39(2), 291-302, 2007) race model inequality (RMI) to distinguish between these two possibilities. Pairs of participants completed a visual enumeration task, both as independent individuals and as two members of a team. The results showed that team performance exceeded the efficiency of two individuals working independently, indicating that interpersonal interaction underlies the collaborative gains in this task. This interpretation was bolstered by analyses showing that the magnitude of the collaborative benefit was positively mediated by the strength of social affiliation and by the similarity of verbal communication among team members. This research serves as a proof-of-concept that Miller's RMI can differentiate between interactive versus independent effects of collaborative cognition. Moreover, the finding that social affiliation and communication similarity each contribute to the collaborative benefit suggests new avenues of research for establishing the mechanisms supporting collaborative cognition.
