Abstract
Schizotypy denotes psychosis-like experiences, such as perceptual aberration, magical ideation, and social anxiety. Altered physiological arousal from social stress is found in people with high schizotypal traits. Two experiments aimed to determine the relationship of schizotypy to physiological arousal from social stress. Experiment 1 tested the hypotheses that heart rate from social stress would be greater in high, than mild-to-moderate, schizotypal traits, and disorganized schizotypy would explain this effect because of distress from disorganisation. Experiment 1 tested social stress in 16 participants with high schizotypal traits and 10 participants with mild-to-moderate schizotypal traits. The social stress test consisted of a public speech and an informal discussion with strangers. The high schizotypal group had a higher heart rate than the mild-to-moderate schizotypal group during the informal discussion with strangers, but not during the public speech. Disorganized schizotypy accounted for this group difference. Experiment 2 tested the hypothesis that mild-to-moderate schizotypal traits would have a linear relationship with physiological arousal from social stress. Experiment 2 tested 24 participants with mild-to-moderate schizotypal traits performing the abovementioned social stress test while their heart rate and skin conductance responses were measured. Mild-to-moderate schizotypal traits had a linear relationship with physiological arousal during the discussion with strangers. Distress in disorganized schizotypy may explain the heightened arousal from close social interaction with strangers in high schizotypy than mild-to-moderate schizotypy. Mild-to-moderate schizotypal traits may have a linear relationship with HR during close social interaction because of difficulty with acclimatizing to the social interaction.

轻度至中度的精神分裂症性状与社会压力引起的生理唤醒有关
摘要
精神分裂症表示类似精神病的经历,例如知觉性畸变,神奇的想法和社交焦虑。具有高分裂型特征的人发现了社会压力引起的生理唤醒改变。旨在确定精神分裂症与社会压力引起的生理唤醒的关系的两个实验。实验1检验了以下假设:社交压力引起的心率在较高的情况下会比轻度至中度的精神分裂症性状高,而精神分裂症的杂乱无章可解释这种现象的原因是由于精神错乱引起的困扰。实验1测试了16名具有高精神分裂症特征的参与者和10名具有轻度到中度精神分裂症特征的参与者的社会压力。社会压力测试包括公开演讲和与陌生人的非正式讨论。在与陌生人的非正式讨论中,高精神分裂症患者的心率高于轻度至中度精神分裂症患者的心率,但在公开演讲中则没有。杂乱无章的精神分裂症是造成这一群体差异的原因。实验2检验了以下假设:轻度至中度的精神分裂型特征与社会压力引起的生理唤醒具有线性关系。实验2测试了24名具有轻度至中度精神分裂症特征的参与者,进行上述社会压力测试,同时测量了他们的心率和皮肤电导响应。在与陌生人的讨论中,轻度至中度的精神分裂性状特征与生理唤起呈线性关系。混乱的精神分裂症的困扰可能解释了高精神分裂症患者与轻度到中度精神分裂症患者与陌生人的密切社会互动引起的唤醒感增强。轻度至中度的精神分裂性状可能在密切的社会互动中与HR呈线性关系,这是因为难以适应社交互动。
