Deficits in olfactory performance have been reported in schizophrenia but results on subjective odour ratings remain unclear. Compared to controls (N=34), schizophrenia inpatients (N=34) expressed deficits concerning odour threshold, discrimination and identification but intact intensity ratings. Most interestingly, patients showed an increased rating range concerning olfactory hedonic judgements.
嗅觉表现缺陷在精神分裂症中已有报道，但关于主观气味评分的结果仍不清楚。与对照组（N=34）相比，精神分裂症住院患者（N=34）在嗅觉阈值、辨别和识别方面表现出缺陷，但强度评分正常。最有趣的是，患者在嗅觉愉悦判断方面的评分范围增加。
