项目摘要

To investigate how post-event misinformation affect the memory of the original event, an emotional event was introduced to experimental paradigm. As an originalevent, emotional event was used. In first experiment, the influence of emotionalevent was tested. It was strongly shown that an emotional event had an effect to the memory of the post emotional event(anterograde amnesia). In experiment 2, the effect of misinformation to thememory of emotional events was investigated. The result showed that central information of the event was strongly deteriorated retrograde direction.To explore the nature of the post event information in memory, new media was introduced, that is, pictorial post event information was used as stimulus. Furthermore, the timing of presentation of post-event information was introduced. The result showed that, if post-event information was presented immediate before the recognition test, the effect of the information was stronger than when itwas presented immediately after the presentation of original event. False recognition rate went higher when post-event information was introduced immediately after the presentation of original event.To test the modality interaction of the presented events(visual vs. auditory information), news media was introduced. Furthermore, controlled narration(auditory information) was added to the visual events. These stimuli were presented via videotape recording. Three conditions of the presentations were prepared. They were congruent condition, partially congruent condition, and incongruent condition. Recognition test was administered after the presentation of the stimulus.Recognition test was a series of pictures that came from the original video scenes, The expected result that the memory performance for the congruent condition is superior to other conditions was not observed.However, the result indicated future plan of investigation very much.

为探讨事后错误信息对原始事件记忆的影响，本研究采用情绪事件作为实验范式。作为一个原始的事件，情感事件被使用。实验一考察了情绪事件对被试的影响。研究结果表明，情绪事件对情绪事件后的记忆有影响（顺行性遗忘）。实验二考察了错误信息对情绪事件记忆的影响。结果表明，事件的中枢信息呈强烈的逆向劣化趋势，为了探讨事件后信息在记忆中的本质，本研究引入了新的媒体，即以图片作为刺激的事件后信息。此外，还介绍了提交活动后资料的时间安排。结果表明，在再认测验前即刻呈现事件后信息比在再认测验后即刻呈现事件后信息的效果更强。当事件呈现后立即引入事件后信息时，错误识别率更高。为了测试呈现事件（视觉和听觉信息）的模态交互作用，引入了新闻媒体。此外，控制叙述（听觉信息）被添加到视觉事件。这些刺激通过录像带记录。准备了三个演示条件。它们是一致条件、部分一致条件和不一致条件。再认测试是在刺激呈现后进行的，再认测试是一系列来自原始视频场景的图片，没有观察到一致条件下的记忆表现上级其他条件的预期结果，但该结果很好地表明了未来的研究计划。
