While people with schizophrenia report experiencing as much emotion in the presence of emotionally evocative stimuli as do people without schizophrenia, evidence suggests that they have deficits in the anticipation of positive emotion. However, little is known about the anticipation of negative emotion in schizophrenia, thus leaving open whether anticipation deficits are more general. We sought to assess anticipation of positive and negative stimuli across multiple methods of measurement. We measured reported experience and emotion modulated startle response in people with ( = 27) and without ( = 27) schizophrenia as they anticipated and subsequently viewed evocative pictures. People with schizophrenia showed an overall dampened response during the anticipation of positive and negative stimuli, suggesting a more general deficit in anticipatory emotional responses. Moreover, anticipatory responses were related to symptoms and functioning in people with schizophrenia. Together, these findings point to important new directions for understanding emotion deficits in schizophrenia.
虽然精神分裂症患者报告称,在面对引发情绪的刺激时,他们所体验到的情感与非精神分裂症患者一样多,但有证据表明,他们在对积极情绪的预期方面存在缺陷。然而,对于精神分裂症患者对消极情绪的预期了解甚少,因此尚不清楚预期缺陷是否更为普遍。我们试图通过多种测量方法来评估对积极和消极刺激的预期。我们测量了27名精神分裂症患者和27名非精神分裂症患者在预期并随后观看引发情绪的图片时所报告的体验以及情绪调节的惊吓反应。精神分裂症患者在预期积极和消极刺激时,总体反应有所减弱,这表明预期情绪反应存在更普遍的缺陷。此外,预期反应与精神分裂症患者的症状及功能状况有关。这些发现共同为理解精神分裂症患者的情绪缺陷指明了重要的新方向。
