Does chronic nicotine consumption influence visual backward masking in schizophrenia and schizotypy? [PDF]

open access: yesSchizophrenia Research: Cognition, 2015
Nicotine consumption is higher for people within the schizophrenia spectrum compared to controls. This observation supports the self-medication hypothesis, that nicotine relieves symptoms in, for example, schizophrenia patients.

Spatial processing and visual backward masking. [PDF]

open access: yesAdv Cogn Psychol, 2008
Most theories of visual masking focus prima-rily on the temporal aspects of visual information processing, strongly neglecting spatial factors. In recent years, however, we have shown that this position is not tenable. Spatial aspects cannot be neglected in metacontrast, pattern and un-masking. Here, we review these results.

Association of the nicotinic receptor α7 subunit gene (CHRNA7) with schizophrenia and visual backward masking [PDF]

open access: yesFrontiers in Psychiatry, 2013
The nicotinic system is involved in the pathophysiology of schizophrenia. However, very little is known about its genetic basis and how it relates to clinical symptoms and potentially pharmacological intervention.

Single-neuron correlates of visual consciousness in human lateral occipital complex [PDF]

open access: yesNature Communications
Conscious perception, a critical aspect of human cognition, is assumed to emerge from a complex network of interacting brain regions that transmit information via feedforward and recurrent pathways.

Thresholds and emergent processes of visual consciousness on color and category in preschoolers and adults [PDF]

open access: yesScientific Reports
Understanding how perception transitions from an unconscious to conscious state is a central aim of visual consciousness research. The threshold is the boundary at which consciousness arises, and the process from unconsciousness to consciousness is the ...

Chinese Character Processing in Visual Masking

open access: yesFrontiers in Psychology, 2022
It has not been clarified if attention influences perception of targets in visual masking. Three forms of common masks (random pattern, para-/metacontrast, and four dots) were thus chosen in the present study and presented with character targets in three

Backward masking reveals coarse-to-fine dynamics in human V1

open access: yesNeuroImage, 2023
Natural images exhibit luminance variations aligned across a broad spectrum of spatial frequencies (SFs). It has been proposed that, at early stages of processing, the coarse signals carried by the low SF (LSF) of the visual input are sent rapidly from ...

The Independence of a Simple Visual-Motor Reaction from the Preconscious Component of Sensation during Backward Masking by Two-Color Stimuli

open access: yesЭкспериментальная психология, 2020
The model of visual backward masking in its two-color modification is applicable in the study of the mechanisms of conjugation of the processes of sensory sensation formation and realization of sensorimotor reactions.

The fastest saccadic responses escape visual masking. [PDF]

open access: yesPLoS ONE, 2014
Object-substitution masking (OSM) occurs when a briefly presented target in a search array is surrounded by small dots that remain visible after the target disappears.
