title: Olfactory perception in schizophrenia: the rating range for hedonic judgements is increased during acute episodes.
abstract: 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.
