Both extreme levels of social anhedonia (SocAnh) and extreme levels of perceptual aberration/magical ideation (PerMag) indicate increased risk for schizophrenia-spectrum disorders and are associated with emotional deficits. For SocAnh, there is evidence of self-reported decreased trait positive affect and abnormalities in emotional attention. For PerMag, there is evidence of increased trait negative affect and increased attention to negative emotion. Yet, the nature of more objective emotional abnormalities in these groups is unclear. The goal of this study was to assess attention to emotions more objectively in a SocAnh, PerMag, and control group by using a positive (vs. neutral) mood induction procedure followed by a free writing period. Linguistic analyses revealed that the SocAnh group used fewer positive emotion words than the control group, with the PerMag group falling in between the others. In addition, both at-risk groups used more negative emotion words than the control group. Also, for the control group only, those in the positive mood induction used more positive emotion words, suggesting their emotions influenced their linguistic expression. Overall, SocAnh is associated with decreased positive emotional expression and at-risk groups are associated with increased negative emotional expression and a decreased influence of emotions on linguistic expression.
社交快感缺失（SocAnh）的极端水平和感知偏差/奇幻观念（PerMag）的极端水平均表明精神分裂症谱系障碍的风险增加，且与情感缺陷相关。对于社交快感缺失，有证据表明自我报告的特质积极情感减少以及情感注意力异常。对于感知偏差/奇幻观念，有证据表明特质消极情感增加以及对负面情绪的注意力增加。然而，这些群体中更客观的情感异常的本质尚不清楚。本研究的目的是通过使用积极（相对于中性）情绪诱导程序，随后进行自由写作期，更客观地评估社交快感缺失组、感知偏差/奇幻观念组和对照组对情绪的注意力。语言分析表明，社交快感缺失组使用的积极情绪词汇少于对照组，感知偏差/奇幻观念组则介于两者之间。此外，两个风险组使用的消极情绪词汇均多于对照组。同样，仅对于对照组而言，处于积极情绪诱导下的人使用了更多的积极情绪词汇，表明他们的情绪影响了他们的语言表达。总体而言，社交快感缺失与积极情绪表达减少相关，而风险组与消极情绪表达增加以及情绪对语言表达的影响减少相关。
