Sensory processing in schizophrenia: missing and avoiding information.

The possible coexistence of supersensitivity and overinhibition (Schizophrenia: Origins, Processes, Treatment and Outcome (1993) 335-350) in schizophrenia was studied using the Adult Sensory Profile as a measure of Dunn's (Infants Young Children 9 (1997) 23-25) model of sensory processing. The quadrant model describes sensory sensitivity, sensation avoiding, low registration and sensation seeking as behavioral responses to sensation. Individuals with schizophrenia (N = 27), bipolar disorder (N = 30) and mentally healthy controls (N = 29) were compared using the Adult Sensory Profile.
