A distinct challenge of implicit self-esteem research is the dubious validity of measures for implicit self-esteem. We conducted two event-related potential (ERP) studies to examine whether implicit self-esteem measured by the Implicit Association Test (IAT) actually reflects the automatic self-evaluation. We adopted the regular IAT and the Go/No-go Association Task (GNAT), respectively, to measure implicit self-esteem in two studies. We focused on the P300 that reflects the stimulus evaluation process. Study 1 revealed that participants responded faster to self pairing with good than to self pairing with bad whereas self pairing with bad elicited a delayed P300 compared with self pairing with good. Study 2 replicated these findings and further highlighted that the index of implicit self-esteem based on reaction time is correlated with that based on P300 latency. Our results suggest that implicit self-esteem assessed by the IAT measures automatic self-evaluation, thus providing neural evidence for the validity of implicit self-esteem.
内隐自尊研究的一个明显挑战是内隐自尊测量的有效性值得怀疑。我们进行了两项事件相关电位（ERP）研究，以检验内隐联想测验（IAT）测量的内隐自尊是否真的反映了自动自我评价。我们分别采用常规的 IAT 和 Go/No-go 联想任务（GNAT）在两项研究中测量内隐自尊。我们关注反映刺激评价过程的 P300。研究 1 表明，与自我配对与坏相比，参与者对自我配对与好的反应更快，而与自我配对与坏相比，自我配对与好引发的 P300 延迟。研究 2 复制了这些发现，并进一步强调，基于反应时间的内隐自尊指数与基于 P300 潜伏期的指数相关。我们的研究结果表明，IAT 测量的内隐自尊反映了自动自我评价，从而为内隐自尊的有效性提供了神经证据。
