Evidence for sensory prediction deficits in schizophrenia

Shergill, Sukhwinder S., Samson, Gabrielle, Bays, Paul M., Frith, Chris D., Wolpert, Daniel M.·2005·American Journal of Psychiatry

Abstract

OBJECTIVE: Patients with schizophrenia experiencing delusions and hallucinations can misattribute their own actions to an external source. The authors test the hypothesis that patients with schizophrenia have defects in their ability to predict the sensory consequences of their actions. METHOD: The authors measured sensory attenuation of self-produced stimuli by patients with schizophrenia and by healthy subjects. RESULTS: Patients with schizophrenia demonstrated significantly less sensory attenuation than healthy subjects. CONCLUSIONS: Patients with a diagnosis of schizophrenia have a dysfunction in their predictive mechanisms.

  • The simulation results across different levels of self-generated force are remarkably similar to empirical results.

    “These results are remarkably similar to those obtained empirically (right panel – reproduced from Shergill et al., 2005) and reveal sensory attenuation through an illusory increase in the self-generated force, relative to matched forces over a wide range of forces.”

  • Subjects with schizophrenia do not show the force-matching illusion.

    “Furthermore, subjects with schizophrenia – who are prone to positive symptoms like delusions – do not show the force-matching illusion (Shergill et al., 2005).”

  • While numerous studies show that schizophrenia patients exhibit subnormal sensory attenuation to their own physical actions, including subnormal N1-suppression to overt speech, there is little empirical evidence that they show sensory attenuation deficits to self-generated mental actions such as inner speech.

    “However, while numerous studies have provided empirical evidence showing that schizophrenia patients exhibit subnormal levels of sensory attenuation to their own physical actions (Whitford et al., 2011; Blakemore et al., 2000b; Shergill et al., 2005), including subnormal levels of N1-suppression to overt speech (Ford et al., 2001a; Ford et al., 2007b; Ford et al., 2001c), there is little empirical”

  • In normal conditions, a system of self-monitoring enables the prediction of the sensory consequences of one's motor acts.

    “In normal conditions, a system of self-monitoring enables the prediction of the sensory consequences of one's motor acts.”

  • Shergill et al. indicated that schizophrenia patients were more accurate than controls when matching an externally applied force, revealing a failure in the normal sensory attenuation mechanism.

    “The authors indicated that patients who suffered from schizophrenia were more accurate compared with controls when matching the externally applied force, which revealed a failure in the normal sensory attenuation mechanism.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
