Task demonstrability defines the criteria that, when met, facilitate the effective exchange of knowledge within a problem-solving group. The extent to which those criteria are met should vary as a consequence of the relevant experiences that members have prior to entering the group. We investigate whether group members’ ability to coordinate with one another is facilitated by their prior task-related experiences. Participants worked individually, then in groups, and then individually again to complete a series of circuit board assembly tasks. Groups in which all members had pre-task experience performed significantly better than groups with even a single member lacking task experience, or individuals. Mediation analysis showed that prior task experience helps group members coordinate by improving task demonstrability. Group experience composition also affected post-group individual performance. Groups with diverse task experience produced individuals who performed better solo but only after working on an unstructured task that allowed for greater exploration.

任务可证明性定义了在满足时促进问题解决小组内有效交流知识的标准。满足这些标准的程度应根据成员在进入小组之前的相关经验而有所不同。我们调查小组成员相互协调的能力是否受到他们先前与任务相关的经验的促进。参与者单独工作，然后分组工作，然后再次单独完成一系列电路板组装任务。所有成员都具有任务前经验的小组的表现明显好于即使是单个成员缺乏任务经验的小组或个人。中介分析表明，先前的任务经验通过提高任务可证明性来帮助小组成员进行协调。小组经验构成也影响了小组后的个人表现。具有不同任务经验的小组产生的个人表现更好，但只有在完成一项允许更大探索的非结构化任务之后。
