摘　　要：以往研究表明对死亡不可避免性的认识使人类产生死亡焦虑,并且为了降低该焦虑,年轻人倾向于抑制生理自我加工;然而相比年轻人,老年人对死亡的接受程度更高,并且自我抑制能力减弱。因此本研究采用死亡启动范式,探讨了死亡对自我相关记忆的影响以及可能存在的年龄差异。实验一以大学生为被试,结果发现死亡启动后,个体对自我相关信息的再认率显著低于消极启动后;实验二以老年人为被试,结果发现死亡启动后,个体对自我相关信息的再认率与消极启动后无差异。上述结果说明,死亡启动对自我相关记忆的影响存在年龄差异。在大学生中,死亡启动使个体抑制自我相关信息,而在老年人中该抑制效应并不存在。Self-awareness may contribute to our concerns about mortality by facilitating the realization of the inevitability of death. The more aware one is about one＇s existence,the more salient and inescapable the problem of nonexistence is. When people are thinking about their own death or when death-related thoughts are in their current focal awareness,they are motivated to avoid attention on the self to reduce death anxiety. Despite growing research interested in the effect of mortality salience on self-related information,no studies so far have examined the effect from the perspective of mental self. In addition,the effect has been demonstrated in numerous experiments with young adults as participants but has rarely been tested in older individuals. And previous studies have shown that there are many differences between the younger and older. For example,death anxiety of the elderly is lower than the younger. Using a mortality salience priming task and self-referential paradigm,the present study investigated the impact of mortality salience on self-related information from the perspective of mental self as well as the age differences on the effect. We speculated that the younger would avoid self-referential cognitive processes under mortality threats from the perspective of mental self,but the older would not.In experiment 1,a 2（group： mortality salience,negative affect） × 3（referential target： self,celebrity,valence） mixed experimental design was adopted. Fifty-five healthy college students were included in the experiment and randomly divided into the mortality salience group and the negative affect group. Participants in mortality salience group were asked to answer two open questions about death,and participants in negative affect group were presented with 28 statements that were related to negative emotion. All participants first finished the priming task followed by a manipulation check of the priming effect. After that,each participant was asked to perform 40 calculations in 5 minutes,which serve
