Abstract:
The goal of this paper is to examine the possibility of using emotion-induction words in audio guide for the learning of visual contents by extending the study that focused on the provision timings of visual and auditory information (Hirabayashi et al., 2020). Thirty emotion-induction words were extracted from the database and categorized into positive, negative, and neutral words. Three experiments were carried out. The first experiment was conducted to confirm the reliability of the emotional values. The result showed a good consistency between the values on the database and the ratings given by the participants. The second experiment was for examining whether the consistency is maintained if the words appeared in sentences. The result confirmed the expectation but showed larger individual differences compared with the first experiment. The third experiment was conducted to examine the effect of emotion-induction words used in audio guide for explaining the visual contents on memor
y. The results showed that the participants who were exposed to the positive and negative emotion-induction words, remembered the content better than those who were presented with neutral triggers. Through the three experiments, the emotion value of the neutral words were found to be sensitive to the context in which they were embedded, which was confirmed by observing the changes of pupil diameter. Suggestions for designing audio and visual contents by using emotion-induction words for better memory are provided.
