Abstract
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.
