Abstract

Compared to unaffected observers patients with schizophrenia (SZ) show characteristic differences in visual perception, including a reduced susceptibility to the influence of context on judgments of contrast - a manifestation of weaker surround suppression (SS). To examine the generality of this phenomenon we measured the ability of 24 individuals with SZ to judge the luminance, contrast, orientation, and size of targets embedded in contextual surrounds that would typically influence the target's appearance. Individuals with SZ demonstrated weaker SS compared to matched controls for stimuli defined by contrast or size, but not for those defined by luminance or orientation. As perceived luminance is thought to be regulated at the earliest stages of visual processing our findings are consistent with a suppression deficit that is predominantly cortical in origin. In addition, we propose that preserved orientation SS in SZ may reflect the sparing of broadly tuned mechanisms of suppression. We attempt to reconcile these data with findings from previous studies.

  • The findings are not at odds with the decreased susceptibility to some visual illusions observed in schizophrenic patients.

    “Our findings are therefore not at odds with decreased susceptibility to some visual illusions in schizophrenic patients (37,38,40,41).”

  • The previously reported reduced spontaneous disambiguation of two-tone images in established schizophrenia is most likely related to early and midlevel visual deficits affecting perceptual organization, context processing and integration, rather than to top-down influences from high-level visual cognition.

    “This previous effect is most likely related to well-established schizophrenic deficits in early and midlevel vision that affect perceptual organization, context processing and integration (37,38,(48)(49)(50)(51)(52)(53) rather than to top-down influences from high-level visual cognition as in the current study.”

  • Yang et al. and Tibber et al. hypothesized that pre-cortical stages of the visual system, in which luminance is supposed to be processed, were spared, thereby contradicting Norton's conclusions.

  • Yang et al. (2012) and Tibber et al. (2013) found that luminance context processing was similar in patients and controls, whereas the strength of illusions was inferior in patients for other psychophysical parameters (e.g., contrast, orientation, size or motion).

  • Some authors have argued that the impairment of gain control is a robust and significant property of visual processing in schizophrenia, and may even consider it a core feature of the disorder.

    “Some authors have argued, in line with the findings that stem from the study of VIs, that the impairment of gain control is a robust and significant property of visual processing in schizophrenia, and may even consider it a core feature of the disorder (Robol et al., 2013; Tibber et al., 2013).”

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.
