ABSTRACT

The present research aimed to devise a test of source recognition that facilitates access to source information stored in memory. Therefore, we extended the standard source-monitoring paradigm, in which items are presented in a source-neutral manner during test, by a second, subsequent test with source reinstatement. In this second test, items (i.e., words) were presented with both study sources (i.e., two speakers) consecutively such that for originally studied words, one test presentation was the exact reinstatement of the original source. To validate our assumption that the test with reinstatement primarily assesses source storage, we manipulated source storage by varying encoding frequency between-participants (repetition vs. no repetition of each item-source-pair). Additionally, we varied source similarity between-participants (similar vs. dissimilar speakers). Data analyses (N = 146) based on multinomial and signal detection models showed a source memory enhancement in the second test with reinstatement compared to the first standard test, especially for similar sources. Additionally, repetition selectively benefited source memory in the second test, validating our interpretation of the second test as a measure for source storage. Altogether, our novel source recognition test offers a promising method for investigating various well-known source memory phenomena more comprehensively.

摘要

本研究旨在设计一种源识别测试，以方便访问存储在内存中的源信息。因此，我们扩展了标准的源监控范式，其中项目在测试期间以源中立的方式呈现，通过第二次后续测试与源恢复。在第二个测试中，项目（即单词）与两个研究来源（即两个说话者）连续呈现，这样对于最初学习的单词，一个测试呈现是原始来源的精确恢复。为了验证我们的假设，即恢复测试主要评估源存储，我们通过改变参与者之间的编码频率（重复与不重复每个项目源对）来操纵源存储。此外，我们改变了参与者之间的来源相似性（相似与不相似）。不同的扬声器）。数据分析（N  = 146）基于多项式和信号检测模型显示，与第一次标准测试相比，第二次测试中的源记忆增强，尤其是对于类似的源。此外，在第二个测试中，重复有选择地有益于源记忆，验证了我们将第二个测试作为源存储度量的解释。总而言之，我们新颖的源识别测试为更全面地研究各种众所周知的源记忆现象提供了一种有前途的方法。
