Spatial language, visual attention, and perceptual simulation.
Spatial language descriptions, such as The bottle is over the glass, direct the attention of the hearer to particular aspects of the visual world. This paper asks how they do so, and what brain mechanisms underlie this process. In two experiments employing behavioural and eye tracking methodologies we examined the effects of spatial language on people's judgements and parsing of a visual scene....
متن کاملEarly dissociation between neural signatures of endogenous spatial attention and perceptual awareness during visual masking
THE RELATIONSHIP BETWEEN SPATIAL ATTENTION AND CONSCIOUS ACCESS HAS OFTEN BEEN PICTURED AS A SINGLE CAUSAL LINK: spatial attention would provide conscious access to weak stimuli by increasing their effective contrast during early visual processing. To test this hypothesis, we assessed whether the early attentional amplification of visual responses, around 100 ms following stimulus onset, had a ...
متن کاملSpatial and temporal coherence in perceptual binding.
Component visual features of objects are registered by distributed patterns of activity among neurons comprising multiple pathways and visual areas. How these distributed patterns of activity give rise to unified representations of objects remains unresolved, although one recent, controversial view posits temporal coherence of neural activity as a binding agent. Motivated by the possible role o...
متن کاملComparing perceptual judgment and subjective measures of spatial awareness.
Spatial awareness is important in domains where safety hinges on human operators keeping track of the relative locations of objects in the environment. While a variety of subjective and judgment-based measures have been used to evaluate spatial awareness, none have probed all three of its levels: (1) identification of environmental objects, (2) their current locations relative to the operator, ...
متن کاملCapture of Attention to Threatening Stimuli without Perceptual Awareness
Visual images that convey threatening information can automatically capture attention. One example is an object looming in the direction of the observer-presumably because such a stimulus signals an impending collision. A critical question for understanding the relationship between attention and conscious awareness is whether awareness is required for this type of prioritized attentional select...
