Previous studies with electroencephalography (EEG) have shown that SWB can be related to frontal alpha asymmetry (FAA). While those studies only considered a single SWB score for each experimental session, our goal is to investigate such a correlation for individuals with a possibly different SWB every 60 or 30 s. Therefore, we conducted two experiments with 30 participants each. We used different temperature and humidity settings and asked the participants to periodically rate their SWB. We computed the FAA from EEG over different time intervals and associated the given SWB, leading to pairs of (FAA, SWB) values. After correcting the imbalance in the data with the Synthetic Minority Over-sampling Technique (SMOTE), we performed a linear regression and found a positive linear correlation between FAA and SWB. We also studied the best time interval sizes for determining FAA around each SWB score. We found that using an interval of 10 s before recording the SWB score yields the best results.<\/jats:p>","DOI":"10.3390\/s23157006","type":"journal-article","created":{"date-parts":[[2023,8,8]],"date-time":"2023-08-08T12:45:53Z","timestamp":1691498753000},"page":"7006","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Analysis of the Correlation between Frontal Alpha Asymmetry of Electroencephalography and Short-Term Subjective Well-Being Changes"],"prefix":"10.3390","volume":"23","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0183-7067","authenticated-orcid":false,"given":"Betty","family":"Wutzl","sequence":"first","affiliation":[{"name":"Graduate School of Information Science and Technology, Osaka University, Suita 565-0871, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3691-3675","authenticated-orcid":false,"given":"Kenji","family":"Leibnitz","sequence":"additional","affiliation":[{"name":"Graduate School of Information Science and Technology, Osaka University, Suita 565-0871, Japan"},{"name":"Center for Information and Neural Networks (CiNet), National Institute of Information and Communications Technology, Suita 565-0871, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daichi","family":"Kominami","sequence":"additional","affiliation":[{"name":"Graduate School of Information Science and Technology, Osaka University, Suita 565-0871, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9784-627X","authenticated-orcid":false,"given":"Yuichi","family":"Ohsita","sequence":"additional","affiliation":[{"name":"Graduate School of Information Science and Technology, Osaka University, Suita 565-0871, Japan"},{"name":"Institute for Open and Transdisciplinary Research Initiatives, Osaka University, Suita 565-0871, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michiko","family":"Kaihotsu","sequence":"additional","affiliation":[{"name":"Technology Innovation Center, Daikin Industries, Ltd., Settsu 566-8585, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Masayuki","family":"Murata","sequence":"additional","affiliation":[{"name":"Graduate School of Information Science and Technology, Osaka University, Suita 565-0871, Japan"},{"name":"Center for Information and Neural Networks (CiNet), National Institute of Information and Communications Technology, Suita 565-0871, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,8,7]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"276","DOI":"10.1037\/0033-2909.125.2.276","article-title":"Subjective Well-Being: Three Decades of Progress","volume":"125","author":"Diener","year":"1999","journal-title":"Psychol.
