Contrast sensitivity for stationary and drifting spatial frequency gratings in positive- and negative-symptom schizophrenia
Open accessAbstract
To investigate the transient channel deficit hypothesis in schizophrenia, the authors measured the contrast sensitivity for stationary and drifting gratings in groups with positive- and negative-symptom schizophrenia. The negative-symptom group showed a significant reduction in contrast sensitivity for stationary and drifting gratings at low, medium, and high spatial frequencies in comparison to the control group. There were no differences in contrast sensitivity between the control and positive-symptom groups for stationary and drifting gratings at low-spatial frequencies, but there were significant reductions at medium and high spatial frequencies. The results are consistent with a disorder in both sustained and transient channels in negative-symptom schizophrenia and a disorder in sustained channels in positive-symptom schizophrenia.

Each is checked against this paper’s own text: does it say what the citing paper says it does?
In the citing paper
“Although behavioral studies have found contrast sensitivity deficits across spatial frequencies, often thresholds are relatively low (e.g., < 10% contrast; [20]), limiting P-pathway involvement.”
From Visual perception and its impairment in schizophrenia (2008) · cites this paper as [20]
In the citing paper
“Patients with schizophrenia show preferential M-pathway dysfunction (21,22,28,35–38), although deficits have also been observed in parvocellular processing (19,20).”
From Visual perception and its impairment in schizophrenia (2008) · cites this paper as [20]
In the citing paper
“First, patients with schizophrenia show decreased contrast sensitivity (i.e., need more contrast to detect a grating) across a range of grating-sizes in behavioral studies (19,20).”
From Visual perception and its impairment in schizophrenia (2008) · cites this paper as [20]
In the citing paper
“There is also evidence that gain control deficits, seen in contrast detection and M-pathway deficits, are important in predicting outcome (22,45), and are related to higher-level problems in perceptual organization (28,46) and to symptomatology (20,47–51).”

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.
