Differences in Emotion Signals Based on Gender According to EEG Signal Record

Abstract:

Emotions are complex responses influenced by physiological systems and environmental conditions. Societal stereotypes often depict that women are more emotional than men, although some researchers are still trying to show a clear biological basis for this assumption. Therefore, it is important to explore gender differences in emotional responses from a neurological perspective. This study aims to investigate gender differences in emotional responses using EEG (Electroencephalography) recordings, focusing on Power Spectral Density (PSD) analysis to compare the level of brain activity in men and women during the emotional states of "happy" and "sad", looking at specific frequency ranges. We recorded EEG signals from 16 participants (8 men and 8 women). We calculated PSD feature values for the Alpha, Beta, and Gamma frequency ranges, specifically in the F8 and FP2 channels related to emotional processing. The results showed that women had higher PSD values in the "happy" condition, especially in the F8 and FP2 channels, indicating greater brain activity compared to men. However, in the "sad" condition, women had lower PSD values than men. These findings suggest that women may experience or express happiness with more intense brain activity than men. Implications of this research include the development of more effective cognitive and emotional therapies with a gender-specific approach, as well as a deeper understanding of gender-specific neural mechanisms in emotional responses.
