Estimation of Concentration by Power Spectrum Analysis Using Auditory Steady-State Response

Abstract

Concentration is closely related to any person, and there is a growing trend to estimate concentration to improve work efficiency and learning efficiency. In order to measure concentration, there is a method of phase analysis using auditory steady-state response (ASSR), but it is time-consuming to calculate. Therefore, the purpose of this study was to measure concentration using power spectrum analysis with the ASSR. The power spectral density of the ASSR was found to increase with the increase of concentration at the F3 electrode. This study suggests that the power spectral density of the ASSR can be a new index for measuring concentration.
