전두엽 알파파 비대칭성과 내재화 증상 및 성격적 특성과의 관계 : 특질모델과 능력모델의 비교

Abstract

This preliminary study explored the clinical utility of frontal alpha asymmetry (FAA), an index reflecting the difference in alpha wave intensity between the left and right frontal lobes, by investigating its relationship with internalizing symptoms and personality traits. Thirty non-clinical university students in their 20s participated in the study. FAA was measured during resting and stress-induced states to compare the explanatory power of the dispositional model and the ca pability model. The results revealed significant negative correlations between stress-induced FAA and anxiety and depression symptoms. Additionally, the difference between resting FAA and stress-induced FAA also showed a significant negative correlation with depression symptoms. In terms of personality traits, stress-induced FAA and the difference between resting and stress-induced FAA were significantly correlated with neuroticism. In contrast, resting FAA did not exhibit significant relationships with either internalizing symptoms or personality traits. These findings suggest that the capability model provides a more accurate explanation for the relationship between FAA, internalizing symptoms, and personality traits. This study highlights the potential of stress-induced FAA as a biological marker for predicting internalizing symptoms and neurotic tendencies. Furthermore, it contributes to expanding the cultural diversity of FAA research data, addressing a topic that has been relatively unexplored in the domestic context.
