参与者玩了一个电子游戏，在这个游戏中，他们被要求对武装和非武装的目标做出快速射击/不射击的决定，其中一半是黑人，一半是白人。在游戏过程中记录的事件相关脑电位（ERPs）评估了与目标种族和物体类型相关的注意过程。早期的ERP组件（即P200和N200）区分黑人和白人目标，以及武装和非武装目标。明确测量的文化刻板印象预测了这种种族ERP差异和游戏中的种族偏见。最重要的是，早期ERP成分中的种族差异程度预测了电子游戏中的行为偏见，并调解了文化刻板印象和偏见之间的关系。(c) 2005爱思唯尔公司版权所有。
Participants played a videogame in which they were required to make speeded shoot/don't-shoot decisions in response to armed and unarmed targets, half of whom were Black, half of whom were White. Event-related brain potentials (ERPs), recorded during the game, assessed attentional processes related to target race and object type. Early ERP components (i.e., the P200 and N200) differentiated between Black and White targets, as well as between armed and unarmed targets. Explicitly measured cultural stereotypes predicted both this racial ERP differentiation and racial bias in the game. Most importantly, the degree of racial differentiation in the early ERP components predicted behavioral bias in the videogame and mediated the relationship between cultural stereotypes and bias.
