摘要

研究表明，被试执行任务效应的产生需要意象介入，但意象在该效应中的作用尚不清楚。因此，本研究采用行为和事件相关电位（ERP）技术来探讨意象在SPT效应中的作用。实验采用受试者内设计，具有3种编码类型（表现、图像和语言）× 2级图像（高和低）。实验1的结果显示，行为编码和意象编码的记忆表现均显著高于言语编码，表明SPT效应的存在，且高意象水平的动名词短语比低意象水平的动名词短语具有更大的SPT效应。实验2采用相同的实验设计，运用行为学和ERP技术，发现行为学结果与实验1一致。ERP数据显示，在性能和图像编码条件下，高图像短语的后期正成分大于低图像短语，这表明图像处理是SPT效应产生的关键因素。目前的研究证实了图像对于SPT效应的产生是必要的，并且SPT效应的大小取决于短语的图像水平。

Imagery processing is necessary for the subject-performed task effect: Evidence from event-related potentials

Studies have shown that eliciting the subject-performed task (SPT) effect requires imagery involvement, but the role of imagery in this effect is still unclear. Therefore, this study used behavioral and event-related potential (ERP) technology to explore the role of imagery in the SPT effect. The experiment used a within-subject design with 3 encoding types (performance, imagery, and verbal) × 2 levels of imagery (high and low). The results of Experiment 1 revealed that the memory performance of both performance encoding and imagery encoding was significantly greater than that of verbal encoding, indicating the existence of the SPT effect, and verb–noun phrases with a high-imagery level had a greater SPT effect than low-imagery phrases. Experiment 2 adopted the same experimental design, utilizing behavioral and ERP techniques, and found that the behavioral results were consistent with those of Experiment 1. The ERP data revealed that in the performance and imagery encoding conditions, greater late positive components were observed for high-imagery phrases than for low-imagery phrases, which indicated that imagery processing is the key factor in the generation of the SPT effect. The current study confirmed that imagery is necessary for the generation of the SPT effect and that the size of the SPT effect is dependent on the imagery level of the phrase.

期刊介绍： Learning and Motivation features original experimental research devoted to the analysis of basic phenomena and mechanisms of learning, memory, and motivation. These studies, involving either animal or human subjects, examine behavioral, biological, and evolutionary influences on the learning and motivation processes, and often report on an integrated series of experiments that advance knowledge in this field. Theoretical papers and shorter reports are also considered.
