| Abstract: | 隨著虛擬實境技術越發成熟，不少人開始將其應用於娛樂、教育、醫療等 多個領域，虛擬化身相關研究也日益受到關注。本研究透過自我差異理論，討 論在虛擬實境中，經過客製化的理想虛擬化身外表是否會造成個人感知到「實 際自我」與「理想自我」外表的不一致，是否會導致個人對於自我身體意象受 到負面影響，進而造成身體不滿意上升。本為雙因子實驗法(客製化真實 vs 理想外表、高具身性 vs 低具身性)，最後共有 121 位受試者完成體驗並填答 問卷。研究結果發現客製化虛擬化身能讓受試者感知到真實外表與理想外表之 間的差異，但感知外表差異中介客製化外表與感知身體意象，感知身體意象也 無法中介感知外表差異與身體不滿意。然而，研究發現感知外表差異對於身體 不滿意有直接顯著關係。此外，具身性在本研究中操弄失敗，因此無法觀察到 是否具有調節個人感知外表差異的效果。
As virtual reality (VR) technology continues to advance, it is increasingly being applied across various fields, including entertainment, education, and healthcare. Consequently, research on avatars has garnered growing attention. This study, grounded in Self-Discrepancy Theory ( SDT ), examines whether a customized ideal avatar in a VR environment induces a perceived discrepancy between one's actual self and ideal self in terms of appearance, leading to negative effects on body image perception and increased body dissatisfaction.
A 2×2 factorial experimental design was employed, manipulating avatar appearance (customized actual vs. customized ideal) and embodiment level (high vs. low embodiment). A total of 121 participants completed the VR experience and responded to a questionnaire. The results indicate that customizing an avatar heightened participants' perceived discrepancy between their actual and ideal appearance. However, perceived body image did not mediate the relationship between avatar customization and body dissatisfaction, nor did perceived appearance discrepancy mediate the relationship between perceived body image and body dissatisfaction. Nevertheless, the findings revealed a direct and significant relationship between perceived appearance discrepancy and body dissatisfaction. Additionally, the manipulation of embodiment in this study was unsuccessful, preventing an assessment of whether embodiment moderates the effect of perceived appearance discrepancy. |
