ABSTRACT

Behavioural investigations concerning the influence of cooperation and cheating on the two sub-types of episodic memory (i.e. item memory and source memory), especially on source memory, have shown inconsistent patterns. Besides, the sensitivity of retrieval-relevant neural activities to cooperation and cheating is rarely explored. To delve into these issues, the current study investigated how cooperation and cheating affected old/new effects in item memory and source memory. The results demonstrated that both types of memory elicited four-stage retrieval-relevant processes, indexed by FN400, LPC, LPN, and RFE, respectively. There was moderate to strong evidence that LPC, LPN, and RFE were insusceptible to cooperation and cheating. For the familiarity-based FN400, in item memory, the effect was only identified in the cooperative condition, while in source memory, there was moderate evidence that the effect was comparable between the cooperative and the cheating circumstances. The above data provide no psychophysiological evidence for the cheater-detection strategy.

摘要

有关合作和作弊对情景记忆的两个子类型（即项目记忆和源记忆），特别是对源记忆的影响的行为研究显示出不一致的模式。此外，很少探索与检索有关的神经活动对合作和作弊的敏感性。为了深入研究这些问题，当前的研究调查了合作和作弊如何影响项目记忆和源记忆中的新旧影响。结果表明，两种类型的存储器都引发了四个阶段的检索相关过程，分别由FN400，LPC，LPN和RFE索引。有中度到强烈的证据表明LPC，LPN和RFE不适合合作和作弊。对于基于熟悉度的FN400，在项目内存中，仅在协作条件下才能确定效果，而在源记忆中，有适度的证据表明，合作和作弊情况下的效果是可比的。以上数据没有为作弊者检测策略提供心理生理证据。
