日常生活中的许多共同决定（例如，哪个酒吧比较少人？）依赖于近似计数，但对一起计数的心理特征知之甚少。在这里，我们系统地研究了集体近似计数。成对的参与者在一个2-选择的强迫选择任务中做出个人和集体的枚举判断，当意见不一致时，他们通过口头沟通协商共同决定，并在每次试验结束时收到关于准确性的反馈。结果表明，两个人集体数数比单独数数更好，但在更基本的感知领域（例如，亮度对比度）。此外，这种集体查点得益于先前的非交互式实践，表明如何联合收割机结合关于查点的共享信息的社会学习需要大量的个人经验。最后，集体背景对个人的枚举敏感性产生了积极但短暂的影响。这种短暂的社会影响可以被解释为一种激励因素，它产生于集体成员必须为他们的个人决定负责并面对他们的判断的后果。
Many joint decisions in everyday life (e.g., Which bar is less crowded?) depend on approximate enumeration, but very little is known about the psychological characteristics of counting together. Here we systematically investigated collective approximate enumeration. Pairs of participants made individual and collective enumeration judgments in a 2-alternative forced-choice task and when in disagreement, they negotiated joint decisions via verbal communication and received feedback about accuracy at the end of each trial. The results showed that two people could collectively count better than either one alone, but not as well as expected by previous models of collective sensory decision making in more basic perceptual domains (e.g., luminance contrast). Moreover, such collective enumeration benefited from prior, noninteractive practice showing that social learning of how to combine shared information about enumeration required substantial individual experience. Finally, the collective context had a positive but transient impact on an individual's enumeration sensitivity. This transient social influence may be explained as a motivational factor arising from the fact that members of a collective must take responsibility for their individual decisions and face the consequences of their judgments.
