| Research Abstract |
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.
