EXPLORING THE SAC MODEL OF MEMORY

这一建议的目的是帮助实现内隐和外显记忆现象以及跨越较高水平的概念和较低水平的知觉效应的记忆扭曲的统一模型。SAC代表激活混乱的来源，将通过几种方式进行测试和挑战。首先，做出了可能不确定SAC的新预测(即，不一定是其他帐户所预期的)，其次，将使用SAC在详细水平上对每个数据集进行建模。虽然SAC在解释和拟合某些领域的数据方面取得了一些成功，但仍有许多问题需要探讨，这些问题在上一个供资期间没有得到解决。目标是在更高和更低的描述级别上测试预测。其中包括测试假设，这些假设涉及知觉特征如何与概念特征表征相结合，表征如何随经验变化，即如何以及何时构建更高层次的结构，以及SAC的记忆表征和过程是否以类似的方式工作于阐述(概念加工)和知觉特征(数据驱动加工)。总而言之，我们的目标是通过(A)挑战模型来解释内隐/外显记忆领域中广泛的交叉分离以及记忆虚构，从而进一步测试和试图反驳SAC；(B)在据称的结果已经挑战SAC的解释的领域测试该模型；(C)开发更详细的表征和更完整的编码、匹配和提取的过程模型；以及(D)阐明(在SAC和其他认知理论中)限制理论构建的认知功能的各个方面。这一理论进步将有助于理解人类的记忆，包括记忆的强弱和易犯错误。

The goal of this proposal is to help achieve a unified model of implicit and explicit memory phenomena and memory distortions that span higher level conceptual and lower level perceptual effects. SAC, which stands for Source Of Activation Confusion, will be tested and challenged in several ways. First, novel predictions (i.e., not necessarily expected by other accounts) are made that could disconfirm SAC, and second, each data set will be modeled at a detailed level using SAC. Although SAC has already achieved some success in explaining and fitting data in some domains, there remain many issues to explore that were not addressed during the previous funding period. The goal is to test predictions at higher and lower levels of description. These include testing hypotheses concerning how perceptual features are integrated with conceptual features representations, and how representations change with experience, i.e., how and when higher level structures are built, and whether SAC's memory representation and processes work in an analogous fashion for elaborations (conceptual processing) and for perceptual features (data driven processing). In sum, the goals are to further test and attempt to disconfirm SAC by (a) challenging the model to account for the wide range of cross-over dissociations in the implicit/explicit memory domain, as well as memory confabulations; (b) test the model in domains where purported results already challenge SAC's account; (c) develop a more detailed representation and a more completely specified process model of encoding, matching and retrieval; and (d) shed light on aspects of cognitive functioning that will constrain theory building (within SAC and other cognitive theories). This theoretical advance will be important in helping to understand human memory, both its strength and fallibilities.
