Abstract

Range adaptation refers to the representation of a stimulus value based on its relative position in the range of pre-experienced values. Altered range adaptation in value representation may be related to motivation and pleasure (MAP) deficit in schizophrenia (SCZ). This follow-up study examined the relationship between range adaptation performance and MAP symptoms in SCZ patients. We recruited 26 schizophrenia patients and followed them for 1 year. They completed an experimental task for estimating their range adaptation to outcome value (OV) and expected value (EV) at baseline and after 1 year. At baseline, we found a marginally significant and negative correlation between OV adaptation and avolition symptoms in SCZ patients. Moreover, the 1-year change of EV adaptation was significantly and negatively correlated with the change of self-report pleasure experience. Our results suggest that range adaptation may track the variations of MAP symptoms in SCZ.

精神分裂症的范围适应:一项为期一年的纵向研究
范围适应是指根据刺激值在先前经验值范围内的相对位置来表征刺激值。价值表征范围适应的改变可能与精神分裂症患者的动机和愉悦(MAP)缺陷有关。本研究探讨了SCZ患者的距离适应表现与MAP症状之间的关系。我们招募了26名精神分裂症患者,随访1年。他们完成了一项实验任务,以估计他们在基线和1年后对结果值(OV)和期望值(EV)的范围适应。在基线时,我们发现SCZ患者OV适应与缓解症状之间存在显著负相关。此外,EV适应的1年变化与自我报告愉悦体验的变化呈显著负相关。我们的研究结果表明,范围适应可能跟踪SCZ中MAP症状的变化。
