The relationship between emotion and auditory response with EEG

Abstract

Aim of this study is to the relation between emotion accompanying visual stimulation and auditory steady state response (ASSR). We used International Affective Picture System (IAPS) as an emotional stimulus. The stimulus images presented with three categories of negative, neutral, and positive by valence value with 80 pieces respectively. The charp sound (100Hz to 10kHz) of 55dB was presented 40 times/s and binaural stimulation. Experimental setup followed that one block consisting of 1 second of control image and silence, 2 seconds of stimulus image and chirp sound was repeated 240 times, and stimulus images presented randomly. As a result, negative was significantly larger amplitude than neutral in ASSR average value. (N = 7, p<0.05) It is suggested that the ASSR amplitude may be one of measures for quantitative evaluation between neutral image and negative image.
