Effect of post-event information on original-event memory.

为了研究事件后错误信息如何影响对原始事件的记忆，在实验范式中引入了一个情绪事件。作为一个原始事件，使用了情感事件。在第一个实验中，测试了情绪事件的影响。结果表明，情绪事件对情绪后事件(顺行性健忘症)的记忆有影响。实验二考察了错误信息对情绪事件记忆的影响。结果表明，事件的中枢信息在逆行方向上严重恶化，为了探索事件后信息在记忆中的本质，引入了新媒体，即以图画事件后信息作为刺激。此外，还介绍了事件后信息的呈现时间。结果表明，在再认测验前立即呈现事件后信息的效应要强于在原始事件呈现后立即呈现信息时的效应。在原始事件呈现后立即引入事件后信息的错误识别率较高，为了测试呈现事件(视觉信息和听觉信息)之间的通道交互作用，引入了新闻媒体。此外，受控叙述(听觉信息)被添加到视觉事件中。这些刺激是通过录像带呈现的。准备了三种情况的陈述。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，再认测试是来自原始视频场景的一系列图片，没有观察到一致条件下的记忆成绩优于其他条件的预期结果，但这一结果很好地预示了未来的研究计划。

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.
