Self-related information, due to its high social/adaptive value, seems to have a preferential access to our attentional resources (cf. the cocktail party effect). However, it remains uncertain whether this attention preference is the same for different kinds of self-related cues. In this ERP study we showed that self-name and self-face when compared with other names and faces, produced very similar patterns of behavioral and neural responses, i.e., shorter reaction times (RTs) and enhanced P300. The processing of the two self-related cues did not differ between each other, neither in RTs nor in P300 responses. In fact, the amplitudes of P300 to self-name and self-face were correlated. These results suggest that the adaptive value of different kinds of self-related cues tends to be equal and they engage attention resources to a similar extent.
自我相关信息由于具有较高的社会/适应价值，似乎优先获得我们的注意资源（参见鸡尾酒会效应）。然而，不同种类的自我相关线索是否具有相同的注意偏好尚不确定。在这项 ERP 研究中，我们发现与其他姓名和面孔相比，自我姓名和自我面孔产生了非常相似的行为和神经反应模式，即更短的反应时间（RT）和增强的 P300。两种自我相关线索的处理在 RT 和 P300 反应中彼此之间没有差异。实际上，P300 对自我姓名和自我面孔的幅度呈正相关。这些结果表明，不同种类的自我相关线索的适应价值趋于相等，它们以相似的程度吸引注意力资源。
