In the current study, a gaze-cueing experiment (similar to Dawel et al. 2015) was conducted in which the predictivity of a gaze-cue was manipulated (non-predictive vs highly predictive). This was done to assess the degree to which individuals with elevated psychopathic traits can use contextual information (i.e., the predictivity of the cue). Psychopathic traits were measured with the Self-Report Psychopathy Scale-Short Form (SRP-SF) in a mixed sample (undergraduate students and community members). Results showed no group difference in reaction times between high and non-predictive cueing blocks, suggesting that individuals with elevated psychopathic traits can indeed use contextual information when it is relevant. In addition, we observed that fearful facial expressions did not lead to a change in reaction times in individuals with elevated psychopathic traits, whereas individuals with low psychopathic traits showed speeded responses when confronted with a fearful face, compared to a neutral face. This suggests that fearful faces do not lead to faster attentional deployment in individuals with elevated psychopathic traits.
在当前的研究中,我们进行了一项注视提示实验(类似于达韦尔等人2015年的实验),其中对注视提示的预测性进行了操纵(非预测性与高预测性)。这样做是为了评估具有较高精神病态特质的个体能够利用情境信息(即提示的预测性)的程度。在一个混合样本(本科生和社区成员)中,使用《自陈式精神病态量表简版》(SRP-SF)来测量精神病态特质。结果显示,在高预测性提示组和非预测性提示组之间,反应时间没有组间差异,这表明具有较高精神病态特质的个体在相关情境下确实能够利用情境信息。此外,我们观察到,恐惧的面部表情并未导致具有较高精神病态特质的个体反应时间发生变化,而与面对中性面孔相比,具有较低精神病态特质的个体在面对恐惧面孔时反应速度加快。这表明恐惧面孔不会导致具有较高精神病态特质的个体更快地部署注意力。
