An Object Substitution Theory of Visual Masking
The brief presentation of a visual display, although clearly visible when shown by itself, can be rendered invisible by the subsequent presentation of a second visual display in the same location. Recent studies of backward masking of this kind have revealed several new effects that are not predicted by standard theories of masking. Among these are masking by four small dots that surround but t...
متن کاملMultisensory integration, sensory substitution and visual rehabilitation.
Sensory substitution has advanced remarkably over the past 35 years since first introduced to the scientific literature by Paul Bach-y-Rita. In this issue dedicated to his memory, we describe a collection of reviews that assess the current state of neuroscience research on sensory substitution, visual rehabilitation, and multisensory processes.
متن کاملVisual masking by object substitution in schizophrenia.
BACKGROUND Schizophrenia patients demonstrate impairment on visual backward masking, a measure of early visual processing. Most visual masking paradigms involve two distinct processes, an early fast-acting component associated with object formation and a later component that acts through object substitution. So far, masking paradigms used in schizophrenia research have been unable to separate t...
متن کاملSelection/Substitution of Visual Features for Object Tracking
In this paper we present a method of selection and snbstitution of visual features for carrying out object tracking. The proposed method, in principle, can make use of many visual cues available from a scene such as texture, color, velocity (monocular features) and disparity, vergence (binocular features). For the present experiments we make use of 3 features, namely, texture, optical flow and ...
متن کاملNeural substrates of visual masking by object substitution in schizophrenia.
Despite a well-known behavioral finding of visual backward masking impairment in schizophrenia, its underlying neural mechanism remains obscure. This study examined neural correlates of a distinct type of visual backward masking, object substitution masking (OSM), in schizophrenia. Twenty schizophrenia patients and 26 healthy controls completed a 4-Dot OSM task and three functional localizer ta...
