知覺偏誤中的正向錯覺和自利偏誤在環境適應上具有正向功能，本研究從知覺偏誤、死亡威脅及留職意圖的關聯來探討多元專長工作者（斜槓工作者）如何因應充滿不確定性的工作環境並維持穩定的職涯流動和發展。研究目的為探討多元專長工作者（1）知覺偏誤和留職意圖之間的關係、（2）死亡威脅和留職意圖之間的關係及（3）知覺偏誤、死亡威脅及留職意圖之間的關係。前導研究依據恐懼管理理論（Terror management theory）實驗典範檢核死亡威脅操弄工具之效果，採單因子（死亡威脅：有/無）受試者間實驗設計，結果顯示死亡威脅工具（影片）操弄成功；正式研究採二因子混合實驗設計（死亡威脅：有/無）×（知覺偏誤），探討知覺偏誤（正向錯覺和自利偏誤）、死亡威脅及留職意圖的關聯。本研究透過t檢定、皮爾森積差相關及階層迴歸進行結果分析，發現多元專長工作者的正向錯覺、自利偏誤及死亡威脅在留職意圖上呈現顯著差異，且正向錯覺和留職意圖之間為正相關，自利偏誤和留職意圖為負相關。預測力方面，知覺偏誤（正向錯覺和自利偏誤）和死亡威脅皆能預測多元專長工作者的留職意圖。本研究為新興工作現象和流動現象提供了不同角度的解釋，亦對後續職涯發展研究提出相關建議。

This paper focuses on the relations between multiplicity proficiency worker (i.e. slashie)’s perception bias, mortality salience and intention to stay. Bottomed on of Terror management theory (TMT) paradigm, the first study examined the validity of mortality salience (MS) manipulation. The second study explored the differences of perception bias (positive illusions and self-serving bias) and mortality salience on intention to stay, and further analyzed the variation of intentions under positive illusion, self-serving bias and mortality salience. The result shows that positive illusion and mortality salience strengthen people’s intentions to maintain their present employment patterns. Specifically, there is no significant interaction between perception bias, mortality salience and intention to stay. This paper provided evidence that perception bias and mortality salience participate worker’s career development. The implications of this study and suggestions on career development are discussed.
