事件性前瞻记忆的加工机制：来自ERP的证据

Processing Mechanisms Underlying Event-based Prospective Memory：Evidence from an ERP Study

采用事件相关电位技术，对前瞻记忆的加工机制-----主要是执行前的加工机制进行研究。控制条件为单纯的背景任务，实验条件为背景任务含前瞻记忆任务。对两种条件下非靶线索的行为数据进行比较，结果表明实验条件下被试的反应时显著长于控制条件，可能说明两种条件的认知过程存在差异，这种差异在ERPs上主要体现为刺激呈现200ms以后，两种条件的波形和脑地形图存在显著差异。结果支持预备注意加工和记忆加工理论，也部分支持多重加工理论。

Prospective memory (PM) is the memory for actions to be performed in the future. There are several theories on the processing mechanisms underlying event-based prospective memory， such as the simple activation model， noticing-search model， preparatory attentional processes and memory processes theory， and multiprocess view. They differ from one another on whether PM uses cognitive resources at retrieval. Using behavioral experiments， previous researches have generally examined how a PM task inte
