Outline of Final Research Achievements

Daily life requires many decisions. People with high metacognition may effectively and quickly make decisions. In this study, we studied that the influence of difference between two programs (seminar and lecture) on brain activity during the self-related decision making, using functional magnetic resonance imaging (fMRI). Participants who were 26 young, healthy, right-handed people were divided into 2 program groups. We conducted MRI imaging of all participants before and after the intervention.
As a result, we found some significant brain activation in only S group after intervention as follows; right middle frontal gyrus, right precuneus, right precentral gyrus medial segment, and right anterior cingulate cortex. These results were similar to previous study related to the self-reflection. It suggests that participants' self-reflection ability of Seminar group was progress through intervention. In the future, more sophisticated analysis is required with more participants' data.
