Objective:To explore whether there is self-positivity bias in implicit information processing among college students with depressive traits.Methods:Forty-two college students of the depressive-trait group [Trait Depression Scale (T-DEP) T＞60 and Trait Anxiety Inventory (T-AI) T＜60] and 42 cases of the non-depressive-trait control group [T-DEP and T-AI T＜60] were selected.They performed positive and negative words judgment tasks under self or other primed conditions by adopting the supraliminal attitude-prime paradigm, and the difference in reaction time between the two groups was compared.Result:The interaction effects between primed conditions and emotional words in depressive-trait group were not significant [F (1, 41) =1.56, P=0.218].There was significant interaction effect between primed conditions and emotional words in the control group [F (1, 41) =55.43, P＜0.001], and the reaction time of self-positive words and other-negative words in self-positivity bias was shorter than other-positive words and self-negative words outside the bias [ (602.64±20.03) ms, (654.56±20.41) ms vs. (663.19±20.78) ms, (678.64±20.70) ms, Ps＜0.001].Conclusion:It suggests that there may be no self-positivity bias in the implicit information processing of depressive-trait college students, and non-depressive-trait ones show the implicit self-positivity bias.
