Factors affecting target perceptibility in object substitution masking
Object substitution masking (OSM) refers to the observation that reporting of a briefly presented target item is considerably reduced when a mask remains visible after the target offset. The size of OSM has been said to be critically dependent on the speed with which attention is deployed towards …

Looking through the crowded mask: investigating the effect of distractor number and position in object substitution masking
Object substitution masking (OSM) is a phenomenon wherein a surrounding mask (typically four dots) that onsets with a target but lingers after its offset significantly reduces target perceptibility. OSM was originally postulated to occur only when spatial attention was spread (Di Lollo et al., …

Ambiguous statistics - how a statistical encoding in the periphery affects perception
… We also investigate a phenomena known as Object Substitution Masking (OSM), where the identity of an object is impaired when a sparse, non-overlapping, and temporally trailing mask surrounds that object. We find that different types of grouping of object and mask produce different levels …

Visual Object-Category Processing with and without Awareness
… modulated by visual presentation manipulations. Object-category discrimination by the visual system represents a relatively sophisticated level of representation that may or may not occur in the absence of awareness. Here, electrophysiological measures (scalp-recorded event-related potentials, or …

Visual attention in primates and for machines - neuronal mechanisms
… multiple neurophysiological effects, real-world object localization, and a visual masking paradigm (OSM). In each of the considered fields, the work also advances the current state-of-the-art to better understand this aspect of attention itself. The three chosen aspects highlight that the …
