Impaired perceptual processing and conceptual cognition in patients with anxiety disorders: A pilot study with the binocular depth inversion paradigm
The findings suggest that anxiety patients could have abnormalities in central perceptual processing, top-down processing (conceptual cognition), and reality testing similar to (pro-)psychotic conditions.
Binocular depth inversion as a paradigm of reduced visual information processing in prodromal state, antipsychotic-naïve and treated schizophrenia
The receiver operating characteristic (ROC) curve was analysed, testing prodromal cases versus a clinically relevant sample of non-psychotic patients and controls, which included HC as well as the groups of patients suffering from MDD, BD or D revealing a AUC of 0.70, suggesting the BDII may be useful as an additional neuropsychological test for assessment of patients at high risk for developing schizophrenia.
Neural correlates of binocular depth inversion illusion in antipsychotic-naïve first-episode schizophrenia patients
BDII performance may be linked to cortical thickness and surface area variations in regions involved in “adaptive” or “top–down” modulation and stimulus processing, i.e., frontal and parietal lobes.
Reduced binocular depth inversion in regular cannabis users
Reduced depth inversion illusions in schizophrenia are state-specific and occur for multiple object types and viewing conditions.
It is indicated that people with schizophrenia experience fewer DIIs with a variety of object types and viewing conditions, perhaps because of a lessened tendency to construe any type of object as convex.

What visual illusions teach us about schizophrenia
How illusions have been used to explore and reveal the core features of visual perception in schizophrenia from a psychophysical, neurophysiological and functional point of view are reviewed and an integration of these findings into a common hierarchical Bayesian inference framework is proposed.
An fMRI study of the reverse perspective illusion


Effects of synthetic Δ9-tetrahydrocannabinol on binocular depth inversion of natural and artificial objects in man
A strong impairment of binocular depth inversion due to Dronabinol was found in most classes of objects and the anandamidergic system seems to be involved in areas of visual information processing.
Perceptual and Conceptual Information Processing in Schizophrenia and Depression
The depressive group performed similarly to the schizophrenic group on perceptual tasks but closer to the normal group on conceptual tasks, thereby appearing to be less dependent on a particular information-processing strategy.
Independent Effects of Lighting, Orientation, and Stereopsis on the Hollow-Face Illusion
Three experiments were conducted to investigate factors contributing to the ‘hollow face’ illusion. A novel method was employed in which the distance from the mask at which the illusion became
Binocular Depth Inversion Sometimes a solid object seen with both eyes can seem to reverse perspective. A study of this geometrically irrational experience suggests that ordinary depth perception is
The functional organization of human extrastriate cortex: a PET-rCBF study of selective attention to faces and locations
The functional dissociation of human extrastriate cortical processing streams for the perception of face identity and location was investigated in healthy men by measuring visual task-related changes
A Comparison between the Hollow-Face and ‘Hollow-Potato’ Illusions
It is argued previously that an effect of inversion on the hollow-face illusion was evidence that object-specific knowledge was important but not essential in generating the illusion of depth reversal, and that the residual illusory effect for the inverted face to an additional preference of the visual system for convexity.
Impaired central error-correcting behavior in schizophrenia.
The results suggest that schizophrenics are deficient in the ability to monitor ongoing motor behavior on the basis of internal, self-generated cues.
Experiences of alien control in schizophrenia reflect a disorder in the central monitoring of action.
Patients with experiences of alien control of their thoughts and actions who formed a subgroup of those classified as schizophrenic, were significantly less likely to make error corrections in the absence of visual feedback.
