Masking by object substitution: dissociation of masking and cuing effects.
In a newly discovered form of visual masking, a target stimulus is masked by 4 flanking dots if their offset is delayed relative to the target (V. Di Lollo, J. T. Enns, & R. A. Rensink, 2000). In Di Lollo et al. (2000), the dot pattern also cued the relevant target and therefore required deliberate attention. In the present Experiments 2-6, a central arrow cued 1 of 2 letters for an E/F discrim...
متن کاملAsymmetric object substitution masking.
Object substitution masking occurs when a lateral mask persists beyond the duration of a target, reflecting reentrant processes in vision (V. Di Lollo, J. Enns, & R. Rensink, 2000). The authors studied whether substitution masking is location specific and whether it is symmetric around the target. A brief circular display of letters was presented along with a mask that designated the target. Th...
متن کاملLuminance processing in object substitution masking
We probed how processing of luminance increments and decrements interacts with attention dependent substitution masking. Results showed that a target was identified better when surrounded by an opposite polarity mask as compared to the same polarity mask. Opposite polarity mask decreased an effect of distracters, indicating influence on the time of directing attention to a target. The opposite ...
متن کاملAn 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 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...
