Individuals may pay more attention to information about envied targets. Thus, we further investigate the neural correlates underlying the cognitive processing of envy-related stimuli. Participants read information about target persons characterized by two domains: levels of possession and self-relevance of comparison. Event-related potentials (ERPs) were then recorded for three target names (high-envy, moderate-envy, and low-envy) while participants performed a three-stimulus oddball task. The results showed that high- and moderate-envy target names elicited larger P300 amplitudes than did low-envy target names. Specifically, high-envy target names elicited larger P300 amplitudes than did low-envy target names at the left, central, and right sites; in contrast, moderate-envy target names elicited larger P300 amplitudes than did low-envy target names only at central sites. P300 amplitudes did not differ between high- and moderate-envy target names. Thus, we extend previous behavioral findings by showing that people preferentially attend toward envy-related stimuli, as reflected by enhanced P300 amplitudes.
个体可能会更加关注被嫉妒目标的信息。因此，我们进一步研究了与嫉妒相关的刺激的认知加工的神经相关性。参与者阅读了目标人物的信息，这些信息有两个特点：占有水平和自我相关性。然后，参与者在执行三刺激奇偶任务时，记录了三个目标名称（高嫉妒、中嫉妒和低嫉妒）的事件相关电位（ERP）。结果表明，高嫉妒和中嫉妒的目标名称比低嫉妒的目标名称引起更大的 P300 振幅。具体来说，高嫉妒的目标名称在左、中、右部位引起的 P300 振幅比低嫉妒的目标名称大；相反，中嫉妒的目标名称只在中央部位引起的 P300 振幅比低嫉妒的目标名称大。高嫉妒和中嫉妒的目标名称之间的 P300 振幅没有差异。因此，我们通过显示人们更倾向于关注与嫉妒相关的刺激，这反映在增强的 P300 振幅上，扩展了以前的行为发现。
