This laboratory regards human cognitive activity as an information processing system and conducts research to understand its processing process. In our research, we evaluate human cognitive activity by analyzing objective evaluations measured mainly by low-cost electroencephalographs and subjective evaluations collected through questionnaires and other methods. Although the word "psychology" may conjure up images of the humanities, these studies also require knowledge of the sciences in areas such as the analysis of EEG data and statistical processing of questionnaires. From data collection to analysis and evaluation, the methods and contents of these studies are discussed between faculty members and students.
