Object Substitution Masking

Object substitution masking (OSM) refers to afailure of a target to reach conscious awarenesswhen it is surrounded by dots that share a commononset but remain visible after the target isremoved. This effect may reflect reentrant(feedback) visual processes that result in the maskreplacing the target representation. This notion ofsubstitution is present in a variety of topicsregarding spatiotemporal object perception includingthe attentional blink (AB), change blindness, andinattentional blindness. Although a number ofstudies have explored the OSM phenomenon, few haveexamined the depth of processing associated with themasked targets. This book presents work using event-related brain potentials (ERPs) to investigate thedepth of processing issue in OSM by focusing oncomponents tied to specific processing stages.Results are considered within the context ofreentrant processing, as well as how OSM relates toother phenomena such as the AB. This analysis shouldbe useful to researchers studying visual attentionor anyone else interested in how much our brainactually "knows" about unconsciously processedvisual stimuli.

Klappentext
Object substitution masking (OSM) refers to a failure of a target to reach conscious awareness when it is surrounded by dots that share a common onset but remain visible after the target is removed. This effect may reflect reentrant (feedback) visual processes that result in the mask replacing the target representation. This notion of substitution is present in a variety of topics regarding spatiotemporal object perception including the attentional blink (AB), change blindness, and inattentional blindness. Although a number of studies have explored the OSM phenomenon, few have examined the depth of processing associated with the masked targets. This book presents work using event- related brain potentials (ERPs) to investigate the depth of processing issue in OSM by focusing on components tied to specific processing stages. Results are considered within the context of reentrant processing, as well as how OSM relates to other phenomena such as the AB. This analysis should be useful to researchers studying visual attention or anyone else interested in how much our brain actually "knows" about unconsciously processed visual stimuli.
