在最近的一项实证研究中，Starns，Hicks，Brown和Martin（Memory & Cognition，36，1-8 2008）收集了参与者声称是新的旧项目的来源判断，并发现剩余来源的可辨别性取决于新旧反应偏差。作者将他们的发现解释为支持双变量信号检测模型的证据，但反对项目/来源记忆的双高阈值模型。根据后者，新反应仅产生于新旧不确定性状态，对于这种状态，不可能进行来源区分，并且进入这种状态的概率与新旧反应偏差无关。然而，当错过的旧项目提出的来源歧视，参与者可以推断，该项目以前已经研究过。为了测试这种内隐反馈是否会导致第二次提取尝试，从而为可能未识别的项目提供记忆来源，我们复制了Starns等人的研究。的（记忆与认知，36，1-8 2008）发现并比较了他们的程序，没有这样的反馈程序。我们的研究结果挑战的结论，放弃离散处理的源记忆，未识别的项目的源记忆可能是一个人工制品的程序，通过内隐反馈提示参与者重新考虑他们的识别判断时，被要求率的旧项目的来源在项目记忆的情况下。
In a recent empirical study, Starns, Hicks, Brown, and Martin (Memory & Cognition, 36, 1-8 2008) collected source judgments for old items that participants had claimed to be new and found residual source discriminability depending on the old-new response bias. The authors interpreted their finding as evidence in favor of the bivariate signal-detection model, but against the two-high-threshold model of item/source memory. According to the latter, NEW responses only follow from the state of old-new uncertainty for which no source discrimination is possible, and the probability of entering this state is independent of the old-new response bias. However, when missed old items were presented for source discrimination, the participants could infer that the items had been previously studied. To test whether this implicit feedback led to second retrieval attempts and thus to source memory for presumably unrecognized items, we replicated Starns et al.'s (Memory & Cognition, 36, 1-8 2008) finding and compared their procedure to a procedure without such feedback. Our results challenge the conclusion to abandon discrete processing in source memory; source memory for unrecognized items is probably an artifact of the procedure, by which implicit feedback prompts participants to reconsider their recognition judgment when asked to rate the source of old items in the absence of item memory.
