Previous studies indicate that individuals tend to integrate positive information into their self-concept. However, whether such self-positivity bias would still be observed without an explicit self-related cue is unknown. In the present study, 29 participants were asked to evaluate a series of positive and negative trait adjectives, after the participants were presented with their own name or another name subliminally. During the task, their electroencephalograms were recorded. The results showed participants responded faster to positive traits than to negative traits in the self-name cue conditions. In addition, both the latencies and the amplitudes of the N400 showed significant interaction between name-cue and valence in N400 (240-440 ms) amplitudes. The earlier N400 latencies and smaller N400 amplitudes were associated with positive traits in the self-name cue. These results suggested that the self-positivity bias can also be observed in a subliminally presenting self-cue, indicating the robustness of self-positivity bias.

先前的研究表明，个人倾向于将正面信息整合到他们的自我概念中。然而，在没有明确的自我相关提示的情况下，是否仍会观察到这种自我积极性偏见尚不清楚。在本研究中，要求29位参与者对他们的正名或负性状形容词进行一系列的评价，然后将他们的名字或其他名字下位呈现给他们。在任务期间，他们的脑电图被记录下来。结果表明，参与者在自称提示条件下对阳性特征的反应比对阴性特征的反应要快。另外，N400的延迟和幅度都显示了名称提示和价在N400幅度（240-440 ms）中的显着相互作用。较早的N400延迟和较小的N400振幅与自命名提示中的正性状相关。这些结果表明，在下意识呈现的自我提示中也可以观察到自阳性偏差，表明自阳性偏差的鲁棒性。
