“…Performance on catch trials was around chance in this experiment [mean 36.7%, SD 8.2%; t(5) Ͻ 1], where participants' erroneous responses were more likely to be a nonrepeat response than a repeat response (69.6 vs. 25.2% of errors, respectively; the remaining 5.2% of errors were absent responses). This proportion and pattern of catch trial errors are consistent with previous RB studies (Dux and Coltheart 2008).…”

Individuation refers to individuals' use of spatial and temporal properties to register an object as a distinct perceptual event relative to other stimuli. Although behavioral studies have examined both spatial and temporal individuation, neuroimaging investigations of individuation have been restricted to the spatial domain and at relatively late stages of information processing. In this study we used univariate and multivoxel pattern analyses of functional magnetic resonance imaging data to identify brain regions involved in individuating temporally distinct visual items and the neural consequences that arise when this process reaches its capacity limit (repetition blindness, RB). First, we found that regional patterns of blood oxygen level-dependent activity in a large group of brain regions involved in "lower-level" perceptual and "higher-level" attentional/executive processing discriminated between instances where repeated and nonrepeated stimuli were successfully individuated, conditions that placed differential demands on temporal individuation. These results could not be attributed to repetition suppression, stimulus or response factors, task difficulty, regional activation differences, other capacity-limited processes, or artifacts in the data or analyses. Consistent with the global workplace model of consciousness, this finding suggests that temporal individuation is supported by a distributed set of brain regions, rather than a single neural correlate. Second, conditions that reflect the capacity limit of individuation (instances of RB) modulated the amplitude, rather than spatial pattern, of activity in the left hemisphere premotor cortex. This finding could not be attributed to response conflict/ambiguity and likely reflects a candidate brain region underlying the capacity-limited process that gives rise to RB.

“…As is standard in behavioral investigations of RB, catch trials represented 20% of trials to reduce the likelihood of participants guessing "repeat" on trials where they missed the second repeated scene (Dux and Coltheart 2008;Dux 2005a, 2005b). These trials only contained two different intact scenes in the RSVP stream.…”

“…That is, people are 'blind' to the repetition (Bavelier, 1994;Kanwisher, 1987Kanwisher, , 1991Kanwisher, Kim, & Wickens, 1996;Kanwisher & Potter, 1989). Repetition blindness is strongly modulated by factors that manipulate the episodic distinctiveness of the items despite identical timing and stimulus duration parameters (Dux & Coltheart, 2008;Goldfarb & Treisman, 2011). Repetition blindness therefore fundamentally gauges how the visual system assigns object identities over time in the face of rapid input, that is, inferences of object-updating versus object-25 individuation.…”

Object-substitution masking (OSM) refers to when the delayed disappearance of a sparse mask that spatially surrounds but does not overlap the target impairs target perception. Two major theoretical accounts have been offered to explain OSM: the object-substitution account, which stipulates that masking occurs when a separate mask representation replaces the target, and the object-updating account, which espouses that masking is the product of a single representation initially containing information about the target that is modified to reflect the mask. Here I critically review the evidence that has accumulated over two decades for the two models, and find the evidence overwhelmingly in favor of the object-updating account. This object-updating account places OSM in the larger framework of related phenomena such as a repetition blindness, apparent motion, and object correspondence through occlusion that gauge how the visual system assigns episodic object representations in the face of dynamic and ambiguous input. Implications for visual cognition more broadly are discussed. (PsycINFO Database Record

“…Under certain conditions, mostly characterized by insufficient time to consolidate both stimuli, RB occurs instead. Previous research indicates that whether priming or RB occurs depends on whether C1 is attended and tokenized-tokenizing C1 leads to RB, whereas ignoring C1 typically results in priming (Kanwisher, 1987)-as well as how easily C1 and C2 can be distinguished from each other and from other items in the RSVP stream, in terms of low-level perceptual features (Chun, 1997;Dux & Coltheart, 2008). Our finding of repetition priming rather than RB for scene stimuli might reflect the fact that scene processing relies heavily on perceptual features present in the image (as discussed above), which may help to individuate the critical items from the surrounding items in the stream.…”

Two scenes or not two scenes: The effects of stimulus repetition and view-similarity on scene categorization from brief displays

Previous research suggests that understanding the gist of a scene relies on global structural cues that enable rapid scene categorization. This study used a repetition blindness (RB) paradigm to interrogate the nature of the scene representations used in such rapid categorization. When stimuli are repeated in a rapid serial visual presentation (RSVP) sequence (~10 items/ sec), the second occurrence of the repeated item frequently goes unnoticed, a phenomenon that is attributed to a failure to consolidate two conscious episodes (tokens) for a repeatedly activated type. We tested whether RB occurs for different exemplars of the same scene category, which share conceptual and broad structural properties, as well as for identical and mirror-reflected repetitions of the same scene, which additionally share the same local visual details. Across 2 experiments, identical and mirrorimage scenes consistently produced a repetition facilitation, rather than RB. There was no convincing evidence of either RB or repetition facilitation for different members of a scene category. These findings indicate that in the first 100-150 ms of processing scenes are represented in terms of local visual features, rather than more abstract category-general features, and that, unlike other kinds of stimuli (words or objects), scenes are not susceptible to token individuation failure.
