摘要
该研究采用双选择oddball范式,探索不同类型的道德违反事件的时程加工特点。结果发现,不同类型道德违反事件在P2成分上未出现明显差异。在N2成分上,所有道德违反事件和中性事件差异显著,且涉及性的道德违反的波幅大于涉及身体伤害和诚信的道德违反事件。在P300和晚期正成分上,只有涉及性的道德违反事件和中性事件出现差异。结果表明,不同领域的道德违反事件在早期阶段可能存有共同的加工机制,而在后期的加工阶段中开始出现分离趋势。
The study used event-related potentials methods combined with a two-choice oddball paradigm in an attempt to add new evidence to the ＂ unified＂ vs ＂ diverse＂ debate by looking into the online processing of moral judgments. There were no significant differences in the P2 components of different types of immoral behaviors. All three types of immoral words evoked greater N2 amplitudes than neutral words. Words related to sexual disgust elicited the greatest N2 amplitudes. On P300 and late positive components,sexual disgust words induced greater amplitudes than the other conditions. The main results suggest that moral transgressions about physical harm,dishonest and sexual disgust may share a common mechanism in the early stage of online processing and tend to dissociate from each other in the later stage in the time course of processing.
