Statistics

Recomputing p-values needs the paper’s full text.

Claims the paper makes

We couldn’t retrieve this paper’s full text, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • 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.”

    From Shift toward prior knowledge confers a perceptual advantage in early psychosis and psychosis-prone healthy individuals (2015) · cites this paper as [37]

  • 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).”

    From Shift toward prior knowledge confers a perceptual advantage in early psychosis and psychosis-prone healthy individuals (2015) · cites this paper as [37]

  • Patients with psychosis are less sensitive to many perceptual illusions than healthy individuals.

    “especially when considering the fact that patients with psychosis are less sensitive to many perceptual illusions than healthy individuals, 11,[138][139][140]”

    From Are hallucinations due to an imbalance between excitatory and inhibitory influences on the brain? (2016) · cites this paper as [11]

  • Dakin et al. (2005) found that schizophrenia patients were significantly less biased by the surroundings and more accurate in contrast discrimination compared with healthy and psychiatric controls.

    “By manipulating the reference-contrast, the authors noticed that the patients who suffered from schizophrenia were significantly less biased by the surroundings and were thus more accurate in contrast discrimination compared with the healthy and psychiatric controls.”

    From What visual illusions teach us about schizophrenia (2014) · cites this paper as Dakin et al., 2005

  • A disruptive context has less influence on patients than on controls, arguing against nonspecific deficits or lack of attention as an underlying cause of differences.

    “Importantly, like Dakin et al. (27), these authors find that a disruptive context has less influence on patients than on controls, arguing against nonspecific deficits or lack of attention as an underlying cause of differences.”

    From Visual perception and its impairment in schizophrenia (2008) · cites this paper as [27]

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.
