Until recently, it has been thought that under interocular suppression high-level visual processing is strongly inhibited if not abolished. With the development of continuous flash (CFS), a variant binocular rivalry, this notion now challenged by number reports showing even aspects stimuli, such as familiarity, affect time stimuli need to overcome CFS and emerge into awareness. In "breaking suppression" (b-CFS) paradigm, differential unconscious during inferred when (a) speeded detection...
Signals of threat--such as fearful faces--are processed with priority and have privileged access to awareness. This fear advantage is commonly believed engage a specialized subcortical pathway the amygdala that bypasses visual cortex processes predominantly low-spatial-frequency information but largely insensitive high spatial frequencies. We tested detection low- high-pass-filtered neutral faces under continuous flash suppression sandwich masking, we found consistently was specific...
How does one perceive groups of people? It is known that functionally interacting objects (e.g., a glass and pitcher tilted as if pouring water into it) are perceptually grouped. Here, we showed processing multiple human bodies also influenced by their relative positioning. In series categorization experiments, facing each other (seemingly interacting) were recognized more accurately than away from (noninteracting). Moreover, recognition body dyads (but not nonfacing dyads) was strongly...
The detectability of an object in our visual environment is primarily determined by the object's low-level salience, resulting from physical characteristics and its surroundings. In present study we demonstrate that additionally influenced internally generated expectations about properties, these influences are mediated changes perceptual sensitivity. Using continuous flash suppression (CFS) to render objects invisible, found providing valid information category membership (e.g., "car")...
Significance A major challenge for visual perception is to select behaviorally relevant objects from scenes containing a large number of distracting that compete limited processing resources. Here, we show such competitive interactions in human cortex are reduced when distracters positioned commonly experienced configurations (e.g., lamp above dining table), leading improved detection target objects. This indicates the system can exploit real-world regularities group typically co-occur;...

To test whether threatening visual information receives prioritized processing, many studies have examined search for emotional schematic faces. Still, it has remained unclear negative or positive faces are processed more efficiently. We used continuous flash suppression, a variant of binocular rivalry, to render single invisible and measured an advantage in accessing awareness. Across three experiments, were detected quickly than A fourth experiment indicated that this face was unrelated...
Self-relevant information is prioritized in processing. Some have suggested the mechanism driving this advantage akin to automatic prioritization of physically salient stimuli processing (Humphreys & Sui, 2015). Here we investigate whether self-relevant for awareness under continuous flash suppression (CFS), as has been found physical salience. Gabor patches with different orientations were first associated labels You or Other. Participants more accurate matching association, replicating...
The study of unconscious processing requires a measure conscious awareness. Awareness measures can be either subjective (based on participant's report) or objective perceptual performance). preferred awareness depends the theoretical position about consciousness and may influence conclusions extent neural correlates consciousness. We obtained functional magnetic resonance imaging (fMRI) measurements from 43 subjects while they viewed masked faces houses that were subjectively objectively...
Abstract How consciousness arises from brain activity has been a topic of intense scientific research for decades. But how does one identify the neural basis something that is intrinsically personal and subjective? A hallmark approach to ask observers judge stimuli as ‘seen’ (conscious) ‘unseen’ (unconscious) use post hoc sorting measurements based these judgments. Unfortunately, cognitive response biases are known strongly affect place their criterion judging vs. ‘unseen’, thereby...
Breaking continuous flash suppression (bCFS) is a widely used experimental paradigm that exploits detection tasks to measure the time an invisible stimulus requires access awareness. Oneunresolved issue whether differences in times reflect unconscious or conscious processing. To answer this question, here we introduce novel approach (reverse-bCFS [rev-bCFS]) measures initially visible be suppressed from Results two experiments using face stimuli indicate rev-bCFS can capture effects, which...
When incompatible images are presented to the two eyes, one image dominates awareness while other is rendered invisible by interocular suppression. It has remained unclear whether complex visual information can reach high-level processing stages in ventral pathway during such Here, we asked basic face shape, which thought be encoded areas of stream, processed without awareness. We measured aftereffects induced prolonged exposure distorted faces continuous flash Despite constant physical...
Abstract The perception of eye gaze is central to social interaction in that it provides information about another person's goals, intentions, and focus attention. Direction has been found reflexively shift the observer's attention corresponding direction, prolonged exposure averted adapts visual system, biasing subsequent direction opposite adapting face. Here, we tested role conscious awareness coding directions. To this end, measured aftereffects induced by faces with different directions...
A recent focus in the field of consciousness research involves investigating propensity initially non-conscious visual information to gain access consciousness. critical tool for measuring conscious is so-called breaking continuous flash suppression paradigm (b-CFS). In this paradigm, a high contrast dynamic pattern presented one eye, thereby temporarily suppressing target stimulus that other eye. The time it takes observers report (e.g., location of) suppressed provides measure access....
