BACKGROUND: In schizophrenia, perceptual inundation related to sensory gating
deficit can be evaluated « off-line » with the sensory gating inventory (SGI) and
« on-line » during listening tests. However, no study investigated the relation
between « off-line evaluation » and « on-line evaluation ». The present study
investigates this relationship.
METHODS: A sound corpus of 36 realistic environmental auditory scenes was
obtained from a 3D immersive synthesizer. Twenty schizophrenic patients and
twenty healthy subjects completed the SGI and evaluated the feeling of
« inundation » from 1 (« null ») to 5 (« maximum ») for each auditory scene. Sensory
gating deficit was evaluated in half of each population group with P50
suppression electrophysiological measure.
RESULTS: Evaluation of inundation during sound listening was significantly higher
in schizophrenia (3.25) compared to the control group (2.40, P
