Subjects decided whether self-referential statements were true or false. Event-related potentials (ERPs) associated with final words creating false statements displayed a late negativity (N340) relative to ERPs for true completions. The size of this difference between true and false statements was greater for highly familiar statements (e.g. "My name is Ira") than for less familiar ones (e.g. "I go to bed late") even after all the statements had been practised a number of times. The late negativity appears to be associated with a discrepancy between presented and remembered information, and its magnitude reflects the long-term familiarity or strength of the remembered information.
受试者判断自我指涉陈述是真是假。与制造错误陈述的结尾词相关的事件相关电位（ERP）相对于正确完成陈述的ERP显示出晚期负波（N340）。即使所有陈述都已练习多次，对于高度熟悉的陈述（例如“我的名字是艾拉”），真假陈述之间这种差异的大小也大于不太熟悉的陈述（例如“我晚睡”）。晚期负波似乎与呈现的信息和记忆的信息之间的差异有关，其幅度反映了记忆信息的长期熟悉程度或强度。
