We investigated the influences of hostile and non-hostile schemas activations in non-aggressive individuals on their intent attribution processes in various social contexts. 38 non-aggressive participants were randomly assigned to one of two groups, one primed with negative words, to be conditioned as temporarily hostile (TH), and the other with positive words, be conditioned as temporarily non-hostile (TNH). They were asked to read social scenarios composed of positive or negative behaviors of others whose intentions are ambiguous followed by a disambiguation of others' real intentions (hostile vs non-hostile) behind their behaviors. Neural activity related to spontaneous intent attribution processes was measured using electroencephalography (EEG). The results showed that when non-hostile intentions were revealed following ambiguous-negative behaviors of others, the N400 effect was observed only in the TH group. Similarly, when hostile intentions were revealed following ambiguous-positive behaviors of others, the N400 effect was observed only in the TNH group. In other words, non-aggressive individuals were led to attribute either hostile or non-hostile intentions to the same ambiguous behaviors of others depending on which concepts or thoughts (hostile vs non hostile) were activated and accessible in memory by priming at the time of social interactions.
我们研究了非攻击个体中敌对和非敌对模式的激活对其在各种社会情境下意图归因过程的影响。38 名非攻击个体被随机分配到两个组中的一个，一组用负面词汇进行条件作用，被暂时设定为敌对（TH），另一组用积极词汇进行条件作用，被暂时设定为非敌对（TNH）。他们被要求阅读由他人的积极或消极行为组成的社会情境，这些行为的意图是模糊的，然后对他人行为背后的真实意图（敌对或非敌对）进行澄清。使用脑电图（EEG）测量与自发意图归因过程相关的神经活动。结果表明，当他人的模糊消极行为揭示出非敌对意图时，只有 TH 组观察到 N400 效应。同样，当他人的模糊积极行为揭示出敌对意图时，只有 TNH 组观察到 N400 效应。换句话说，非攻击个体根据社交互动时的启动，将敌对或非敌对的意图归因于相同的模糊他人行为，这取决于记忆中激活和可访问的概念或思想（敌对或非敌对）。
