Database_As Far as the Eye Can See: Relationship between Psychopathic Traits and Pupil Response to Affective Stimuli.sav

Database ('Database_As far as the eye can see') used in the publication of article titled 'As far as the eye can see: Relationship between psychopathic traits and pupil response to affective stimuli'.<br>A secondary database ('Database_ValenceArousal_IAPS_IADS_As Far as the Eye Can See' displays data used to assess the relationship between subjective valence/arousal and pupil responses within the article.<br><br>Psychopathic individuals show a range of affective processing deficits, typically associated with the interpersonal/affective component of psychopathy. However, previous research has been inconsistent as to whether psychopathy, within both offender and community populations, is associated with deficient autonomic responses to the simple presentation of affective stimuli. Changes in pupil diameter occur in response to emotionally arousing stimuli and can be used as an objective indicator of physiological reactivity to emotion. This study used pupillometry to explore whether psychopathic traits within a community sample were associated with hypo-responsivity to the affective content of stimuli. Pupil activity was recorded for 102 adult (52 female) community participants in response to affective (both negative and positive affect) and affectively neutral stimuli, that included images of scenes, static facial expressions, dynamic facial expressions and sound-clips. Psychopathic traits were measured using the Triarchic Psychopathy Measure. Pupil diameter was larger in response to negative stimuli, but comparable pupil size was demonstrated across pleasant and neutral stimuli. A linear relationship between subjective arousal and pupil diameter was found in response to sound-clips, but was not evident in response to scenes. Contrary to predictions, psychopathy was unrelated to emotional modulation of pupil diameter across all stimuli. The findings were the same when participant gender was considered. This suggests that psychopathy within a community sample is not associated with autonomic hypo-responsivity to affective stimuli, and this effect is discussed in relation to later defensive/appetitive mobilisation deficits.

本数据集（Database_As far as the eye can see）用于发表题为《放眼望去：精神病态特质与情绪刺激下的瞳孔反应关联》的学术论文。
二级数据集（Database_ValenceArousal_IAPS_IADS_As Far as the Eye Can See）收录了用于本文中评估主观效价（valence）、唤醒度（arousal）与瞳孔反应之间关联的相关数据。

精神病态个体存在一系列情绪加工缺陷，这类缺陷通常与精神病态的人际/情绪维度相关。然而，既往研究对于罪犯群体与社区群体中的精神病态是否与情绪刺激简单呈现下的自主神经反应缺陷存在关联，结论并不一致。瞳孔直径会随情绪唤醒刺激发生变化，可作为情绪生理反应性的客观指标。本研究采用瞳孔测量法（pupillometry），探究社区样本中的精神病态特质是否与刺激情绪内容的反应低下相关。本研究记录了102名成年社区参与者（其中52名为女性）在观看情绪性（包含负性与正性情绪）及情绪中性刺激时的瞳孔活动，刺激类型包括场景图像、静态面部表情、动态面部表情与声音片段（sound-clips）。精神病态特质采用三联型精神病态量表（Triarchic Psychopathy Measure）进行测评。

研究结果显示，参与者对负性刺激的瞳孔直径更大，但愉悦刺激与中性刺激下的瞳孔尺寸无显著差异。在声音片段刺激下，主观唤醒度与瞳孔直径之间存在线性关联，但在场景刺激中未发现该关联。与研究假设相反，在所有刺激类型下，精神病态与瞳孔直径的情绪调节均无关联。在考虑参与者性别因素后，研究结果并未发生改变。

这表明社区样本中的精神病态与情绪刺激下的自主神经反应低下并无关联，本文将就该结果与后续防御/趋动动员缺陷的相关研究展开讨论。
