{"title":"Reflection on Ideas through Verbalisation and the use of the Results","authors":"Y.

This is because the idea is not logically fostered even within the originator himself or herself. One method of defining ideas that have not been formulated within oneself is “reflection.”Especially in the field of education, there have been many studies on how to question one’s own arguments and gain new insights through introspection and objective reflection.In this study, we discuss how the results of verbalizing and reflecting on ideas can be utilized.The Inverted Triangle is a framework for verbalizing and reflecting on ideas.This framework is sometimes used in English education in elementary schools in the United States. In the U.S., where there are many different ethnic groups, there are many families that do not use English at home, so it is used as a teaching tool to help students create logical sentences in English. The contents of the book are summarized by narrowing down the issues from broad to narrow meanings.In my previous research, I examined and improved a framework for reflection of ideas based on the Inverted Triangle. However, so far my research has been limited to examining the contents of the framework itself and improving it.The way to utilize the results of filling out the form has been left to the user’s judgment. In this study, we examined the results of the subjects’ idea reflection, and categorized and staged the methods of utilization.Eight items in the Inverted Triangle have been modified for idea reflection. The experiment was conducted on 9 subjects in January 2019 and 12 subjects in February 2019; the first time, only the Inverted Triangle was filled out, and the second time, a preparation sheet consisting of four items was prepared and filled out in advance.From the results of the questionnaire after completion of the sheet, we qualitatively interpreted the tendency to fill in each item during the reflection, and the contents of the modification of the work after completion of the sheet, and discussed how to utilize the results of the reflection of ideas. As a result, it was found that there are two types of reflection: reflection that deepens the understanding of the content within oneself, and reflection that includes awareness and leads to revision of the work. The method of utilizing the results of reflection was classified according to the tendency.","PeriodicalId":164502,"journal":{"name":"Kansei Engineering","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132742629","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Analysis of How Impressions are Fixed After One Week of Listening to Music Using Subjective Evaluation and Brain Activity Measurement","authors":"Koukichi Kamada, A. Endo, Naoki Takahashi, T. Sakamoto, Toshikazu Kato","doi":"10.54941/ahfe1001763","DOIUrl":"https://doi.org/10.54941/ahfe1001763","url":null,"abstract":"In advertising and marketing, information is often repeatedly presented to consumers to increase their interest and sensitivity. This method is based on what is known in psychology as the ‘mere exposure effect’. In contrast, there is a growing interest in \"neuromarketing,\" the application of brain science ideas to marketing, and the relationship between various psychological effects and brain activity in marketing. Brain measurements have also been used to study the mere exposure effect.However, although there have been various neuroscientific studies and verifications of the mere exposure effect, there have been few experiments that involve multiple exposure to stimuli across days. Therefore, we measured brain activity to investigate the effect of stimulus presentation across multiple days on impressions.In this study, we conducted an experiment in which subjects listened to music every day for a week. On the first day, when the subjects listened to the music for the first time, we conducted subjective evaluations of liking and brain function measurements. The next day, they listened to the music once every day, at home, for five days. On the last day, six days after the first day, we conducted the same subjective evaluation and brain function measurements as on the first day. To create music stimuli that the subjects had never perceived before, an automatic music creation tool was used.During brain activity measurement using optical topography, we focused on the change in the impression of likeability. In optical topography, the change in the concentration of Oxy-Hb in the brain blood flow was measured as a time-series data volume based on functional near-infrared spectroscopy (fNIRS). In the human brain, the amount of Oxy-Hb in specific activity areas increases with time. By measuring the increase and decrease in Oxy-Hb, we can understand how the subject responds to stimuli.We experimented with 10 healthy right-handed undergraduate and graduate students in their 20s (8 men and 2 women, average age 22.6 years) who provided informed consent, following the rules of the Ethics Committee of Chuo University.Consequently, the verification of impression evaluation, which is a subjective evaluation, showed that the impression evaluation increased significantly from the first day to the last day. At this point, it can be said that the mere exposure effect occurred through repeated listening. An analysis of the brain blood flow data showed that the prefrontal cortex became more active during the processing of negative impressions. In particular, the activity of the DLPFC may be deeply involved in the judgment of impressions. Although this was considered a hypothetical event in the previous study, it was clarified in this study without contradicting the data. The results also suggest a new possibility that the brain activity of first impressions can be used to estimate how impressions change in the future. These results may be useful in the field of neuro","PeriodicalId":164502,"journal":{"name":"Kansei Engineering","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115015019","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
