Rapid cortical dynamics associated with auditory spatial attention gradients
Behavioral and EEG studies suggest spatial attention is allocated as a gradient in which processing benefits decrease away from an attended location. Yet the spatiotemporal dynamics of cortical processes that contribute to attentional gradients are unclear. We measured EEG while participants (n = 35) performed an auditory spatial attention task that required a button press to sounds at one targ...
متن کاملImpact of Spatial and Verbal Short-Term Memory Load on Auditory Spatial Attention Gradients
Short-term memory load can impair attentional control, but prior work shows that the extent of the effect ranges from being very general to very specific. One factor for the mixed results may be reliance on point estimates of memory load effects on attention. Here we used auditory attention gradients as an analog measure to map-out the impact of short-term memory load over space. Verbal or spat...
متن کاملComputational modeling of auditory spatial attention
Attention plays a fundamental role in higher-level cognition. In this paper we develop a computational model for how auditory spatial attention is distributed in space. Our model builds on the assumption that attentional bias has bottom-up and top-down components. We represent each component and their synthesis as a map, associating a level of attentional bias to locations in space. The maps an...
متن کاملModelling Auditory Spatial Attention with Constraints
It is well-established that spatial attention can be allocated as a gradient that diminishes from a central focus. In this paper we consider auditory attention and we develop a model for how it is distributed in space following basic ideas of top-down and bottom-up attentional control from verbal models [6, 12]. There are three main components of our model: a goal map, a saliency map, and a pri...
متن کاملTemporal dynamics of divided spatial attention.
In naturalistic settings, observers often have to monitor multiple objects dispersed throughout the visual scene. However, the degree to which spatial attention can be divided across spatially noncontiguous objects has long been debated, particularly when those objects are in close proximity. Moreover, the temporal dynamics of divided attention are unclear: is the process of dividing spatial at...
