When two is too many: Collaborative encoding impairs memory

摘要: Humans routinely encode and retrieve experiences in interactive, collaborative contexts. Yet much of what we know about human memory comes from research on individuals working isolation. Some recent has examined collaboration during retrieval, but not is known how encoding affects memory. We this issue. Participants created episodes by elaborating study materials alone or collaboratively, they later performed a cued-recall task alone, with the partner, different partner (Experiment 1). Collaborative impaired recall. This counterintuitive outcome was found for both individual group recall, even when same partners collaborated across retrieval. impairment significantly reduced, persisted, instructions encouraged free-flowing 2). Thus, collaborative-encoding deficit robust nature likely occurs because produces less effective cues
