本研究的主要目的在於以「恐懼管理理論」（Terror Management Theory; Greenberg, Pyszczynski, & Solomon, 1986）為基礎，探討個體的自我覺察狀態(self-awareness）對其死亡逃避行為之影響。實驗操弄以穿著生化防護衣（CPC）誘發個體之自我覺察狀態，研究者認為當個體穿著CPC時，由於處於密閉狀態，因此可能誘發其自我覺察狀態，此自我覺察狀態可能使個體更加意識到死亡威脅，進而強化其死亡逃避反應。採用2 × 2 二因子完全受詴者間實驗設計，操弄「死亡威脅」（有、無）、「CPC」（有、無）等二個自變項；以死亡相關字詞反應時間作為依變項，並測量個體之自我覺察狀態。研究結果顯示穿著CPC時個體之自我覺察狀態較高，此外「死亡顯著性×CPC」在「死亡字詞反應時間」上有二因子交互作用效果。相較之下，面對死亡威脅時，穿著CPC的受詴者因壓抑死亡訊息，在死亡字詞反應時間上的反應速度較未著CPC者來得慢；同時在著CPC時，個體面對死亡威脅時對死亡字之反應時間，亦比未面對死亡威脅時來得慢。上述結果支持了研究者之假設。

Based on the proximal defense notion of Terror Management Theory, this study examined the effects of mortality salience and Chemical Protective Clothing (CPC) wearing on death-avoiding. It is hypothesized that CPC may induce a state of self-awareness, thus people who wear CPC will exhibit a stronger tendency of death-avoiding than those who do not. A factorial complete randomized design experiment was conducted. 100 military officers were randomly assigned to 2×2 conditions (mortality salience / control group and CPC wear / not). Reaction time（RT）in death-related words and measurement of self-awareness were collected as dependent variables. The results revealed a main effect of CPC on self-awareness.
