隨著社群媒體與數位資訊技術的普及，網路同溫層現象已逐漸成為公共政策與社會運作中的重要議題。既有研究多從演算法機制或媒體使用行為切入，探討網路同溫層的形成過程。然而人格特質作為內在心理因素，其在網路同溫層行為中所扮演的角色，迄今尚未有一致性的研究結論。基於此，本文以人格特質對網路同溫層行為的影響作為主要研究問題，期望從心理特質的角度出發，深化對網路同溫層行為的多元理解。
    本文回顧五大人格特質與網路同溫層之間的相關研究，歸納其可能之關聯性，並據此提出研究問題，進一步以問卷調查資料進行迴歸分析。實證結果顯示，雖然人格特質在部分層面與網路同溫層行為存在關聯，但其影響程度有限；相較之下，政治興趣、網路政治資訊使用與社會背景等外在因素，對網路同溫層行為的影響更為顯著。
    面對網際網路的普及，本文探討人格特質對網路同溫層行為的影響，期望從不同角度進行剖析，以提升對網路同溫層的理解，並提供更多元的討論。

    With the popularization of social media and digital information technologies, the phenomenon of internet echo chambers has gradually become a significant issue in public policy and societal operations. Existing research has mainly examined the formation process of echo chambers from the perspectives of algorithmic mechanisms or media usage behaviors. However, as an internal psychological factor, the role of personality traits in shaping echo chamber behavior remains inconclusive in research findings. Based on this, this study takes the influence of personality traits on internet echo chamber behavior as the primary research question, aiming to deepen the diverse understanding of this phenomenon from the perspective of psychological characteristics.
    This study reviews prior research on the relationship between the Big Five personality traits and internet echo chamber behavior, summarizes the potential associations, proposes corresponding research questions, and further conducts regression analysis using data from a questionnaire survey. The empirical results reveal that while personality traits are associated with echo chamber behavior to some extent, their overall influence is limited. In contrast, external factors such as political interest, internet political information use, and social background exhibit a more significant impact on such behavior.
    With the widespread use of the internet, this study explores the influence of personality traits on internet echo chamber behavior from multiple perspectives, in hopes of enhancing understanding and promoting more diverse academic discussions.
