過去研究顯示不同依戀特質者對自我與他人概念具有不同的內涵，然而在具有不同人際模式的虛擬世界中，個人的依戀特質是否仍影響個體理解自我與他人的概念呢﹖本研究採問卷法，共測量了193位參與者之依戀特質、網路人際信任感以及網路自我確定度，利用群聚分析將受試者分為安全、逃避以及焦慮依戀三組後，進行網路他人信任感與網路自我確定度的多變量變異數分數。研究結果顯示，在網路他人信任感方面，安全與焦慮依戀者，比起逃避依戀者，較容易信任網路他人；而在網路自我確定方面，安全依戀者則比逃避與焦慮依戀者高。此研究結果指出，不同依戀型態的網路使用者，也會將其對應的內在運作模式信念運用在網路情境中。本研究結果顯示，儘管真實與虛擬世界在人際互動的基礎環境上具有相當大的差異，但個人本身所具有的依戀特質，仍具有跨真實與虛擬情境的穩定性，影響個人在真實與虛擬世界中對自我與對他人的理解與看法。

It has been well documented that the Internet has created a whole new world with a whole new set of interpersonal rules. People's real world behavior is assumed to be drastically different from that of the virtual world. The authors, however, believe that some consistency would be maintained down deep in the psychological realm. Attachment style, the primary mental representation of an individual's interpersonal world, would penetrate across situations. Thus, in the present study, the differences among three adult attachment styles on the sense of trust to cyber-other and cyber self-certainty was investigated. One hundred and ninety three students at National Taiwan University participated in this study. They completed three scales measuring attachment orientation, sense of trust to cyber-other, and cyber self-certainty. The results confirmed our hypotheses indicating that people with different attachment styles had significant differences on the sense of trust to cyber-other and cyber self-certainty, and the pattern was consistent with the Attachment Theory, suggesting that persons with different attachment styles tend to exhibit similar attachment characteristics in cyberspace. Thus, although the Internet does provide a rich environment for explorations, people tend to maintain their primary theme in approaching this virtual world. The current research suggests an interactive view to understand interpersonal behaviors on the net.
