Article Abstract
Stimulus rivalry refers to the sustained periods of perceptual dominance that occur when different visual stimuli are swapped at a regular rate between eyes. This phenomenon is thought to involve mainly eye-independent mechanisms. Although several studies have reported that attention can increase image predominance in conventional binocular rivalry, it is unknown whether attention can specifically modulate stimulus rivalry. We addressed this question and manipulated the spatial characteristic of the stimuli to assess whether such an attention modulation could depend on visual processing hierarchy. The results showed that selective attention of stimulus rivalry significantly increased the predominance of the attended stimulus, regardless of the stimulus' spatial characteristics. No effect was observed on the swapping percept. The findings are discussed in the context of recent models attempting to characterize stimulus rivalry between eye-dependent and eye-independent levels.

The human visual system prioritizes dynamic stimuli, which attract attention and more readily break suppression to reach perceptual awareness. Here, we investigated whether dynamic changes in contrast-either increasing or decreasing-are equally effective in facilitating the breakthrough of suppressed stimuli during binocular rivalry. In Experiment 1a, we found that contrast increases led to significantly faster breakthroughs into perceptual dominance compared with decreases.

Binocular rivalry (BR) is a fascinating phenomenon that occurs when the two eyes are presented with dissimilar images, causing observers to perceive continuous alternations between the two images. During BR, cortical activation relies on both stimulus factors (e.g.

Whether it is the first day of school or a new job, individuals often find themselves in situations where they must learn the structure of existing social relationships. However, the mechanisms through which individuals evaluate the strength and nature of these existing relationships - social-relational inference - remain unclear. We posit that linguistic features of conversations may help individuals evaluate social relationships and may be associated with social-relational inference.

Our subjective experience of the sensory information is rich and complex. Yet, typical cognitive and perception psychology paradigms reduce it to a few predefined discrete categories, like yes/no answers or the Likert scales. In the current study, we examined the complexity of subjective visual experience during binocular rivalry, a major experimental paradigm used to study conscious visual perception and its neural mechanisms.

Breaking continuous flash suppression (bCFS) is a widely used experimental paradigm that exploits detection tasks to measure the time an invisible stimulus requires to access awareness. Oneunresolved issue is whether differences in detection times reflect unconscious or conscious processing. To answer this question, here we introduce a novel approach (reverse-bCFS [rev-bCFS]) that measures the time an initially visible stimulus requires to be suppressed from awareness.
