Contributions of lateral inhibition to object substitution masking and attention
Lateral inhibition, the inhibition of neurons by other neurons at the same level, exists at several levels of the visual system. Implications of lateral inhibition for sensory coding and perception have been investigated with a mathematical model that accounts for many properties of metacontrast masking and brief storage of sensory information. Here that model simulates object substitution mask...
متن کاملThe spatial gradient of visual masking by object substitution
A mask that has a common onset but delayed offset with the target produces substitution masking, which can be distinguished from pattern masking and metacontrast masking. This study tests the spatial properties of substitution masking: specificity to the target location and asymmetry to the central and the peripheral sides of the target. Results revealed that substitution declined gradually as ...
متن کاملDissociations among attention, perception, and awareness during object-substitution masking.
When a visual target object is surrounded by four dots that onset at the same time as the target but remain visible after the target terminates, the four dots dramatically impair target discrimination performance. This phenomenon is called object-substitution masking, reflecting the hypothesis that both the target and the four dots are identified, but the representation of the four dots replace...
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 کاملMasking 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...
