Sensory Perception Abnormalities in People at Clinical High-Risk for Psychosis and Those with First-Episode Psychosis

[ Vol. 12 , Issue. 4 ]


Emily K. Bell   Pages 335 - 342 ( 8 )


Abnormalities in basic sensory perception are frequently found in individuals with schizophrenia. However, the literature on basic sensory perception in the clinical high-risk and firstepisode psychosis populations has been less extensive. This article summarizes research on sensory perception in clinical high-risk and first-episode psychosis for the auditory, visual, olfactory, and bodycentered senses. It then highlights the uncertainty of whether sensory perception abnormalities and psychotic symptoms are concurrent results of disruption in normal brain development, or whether abnormal basic sensory experiences play a causal role in the development of psychotic symptoms. Finally, potential directions for future research are discussed.
