并非所有认知协作都同样有效。我们测试了友谊和沟通是否会影响合作效率，方法是随机分配参与者与朋友或非朋友一起完成认知任务，同时对他们的伴侣可见或被隔板隔开。通过将每一对的表现与相同两个人的最佳个人表现模型进行比较，来衡量合作效率。结果是友谊和伴侣可见度之间的强烈互动。当彼此可见时，朋友比非朋友更有效地合作，但是阻止配对成员看到彼此的分区将朋友和非朋友的合作效率降低到类似的较低水平。次要措施表明，口头沟通的差异，但不是心理生理唤醒，促成了这些影响。协方差分析表明，女性比男性的整体水平的合作，但友谊和知名度的相互作用是独立的效果。这些研究结果突出了合作伙伴的知名度在朋友的合作成功的关键作用。
Not all cognitive collaborations are equally effective. We tested whether friendship and communication influenced collaborative efficiency by randomly assigning participants to complete a cognitive task with a friend or non-friend, while visible to their partner or separated by a partition. Collaborative efficiency was indexed by comparing each pair’s performance to an optimal individual performance model of the same two people. The outcome was a strong interaction between friendship and partner visibility. Friends collaborated more efficiently than non-friends when visible to one another, but a partition that prevented pair members from seeing one another reduced the collaborative efficiency of friends and non-friends to a similar lower level. Secondary measures suggested that verbal communication differences, but not psychophysiological arousal, contributed to these effects. Analysis of covariance indicated that females contributed more than males to overall levels of collaboration, but that the interaction of friendship and visibility was independent of that effect. These findings highlight the critical role of partner visibility in the collaborative success of friends.
