Abstract

The second part of this study deals with the behavioral und event-related potential (ERP) findings from the recognition phase of incidental and intentional learning paradigms. Correctly recognized old items were characterized by a significantly more positive ERP in the 400 to 800 ms range when compared to correctly identified new items. Furthermore old words, which had previously been remembered in a free recall test were associated with a more positive ERP when compared to both, correctly recognized and nonrecognized old words. This effect also had an earlier onset latency. The findings are considered in the context of recent results from continuous recognition memory and repetition priming studies. It is concluded that in the present paradigm ERP differences due to recognition can be attributed to unspecific phenomena.

摘要

本研究的第二部分探讨了在附带学习和有意学习范式的识别阶段所获得的行为学及事件相关电位(ERP)研究结果。与正确识别的新项目相比,正确识别的旧项目在400至800毫秒范围内的ERP表现出显著更正向的特征。此外,与正确识别和未被识别的旧单词相比,那些先前在自由回忆测试中被记住的旧单词与更正向的ERP相关联。这种效应的起始潜伏期也更早。这些发现是在连续识别记忆和重复启动研究的最新结果背景下进行考量的。研究得出结论,在当前范式中,由于识别导致的ERP差异可归因于非特异性现象。
