The spatial extent of focused attention modulates attentional disengagement

Psychological Research, 2022
AbstractAttention can be flexibly changed to optimize visual processing: it can be oriented, resized, or even divided. Although much is known about these processes individually, much less is known about how they interact with one another. In the present study we examined how the spatial extent of the attentional focus modulates the efficiency of the ...

Shifts of attention in the early blind: an ERP study of attentional control processes in the absence of visual spatial information [PDF]

, 2006
To investigate the role of visual spatial information in the control of spatial attention, event-related brain potentials (ERPs) were recorded during a tactile attention task for a group of totally blind participants who were either congenitally blind or

Parietal stimulation decouples spatial and feature-based attention [PDF]

, 2008
Everyday visual scenes contain a vast quantity of information, only a fraction of which can guide our behavior. Properties such as the location, color and orientation of stimuli help us extract relevant information from complex scenes (Treisman and ...

Role of right posterior parietal cortex in maintaining attention to spatial locations over time [PDF]

, 2009
Recent models of human posterior parietal cortex (PPC) have variously emphasized its role in spatial perception, visuomotor control or directing attention. However, neuroimaging and lesion studies also suggest that the right PPC might play a special role

Attentional Distribution and Spatial Language [PDF]

, 2014
Whether visual spatial attention can be split to several discontinuous locations concurrently is still an open and intensely debated question. We address this question in the domain of spatial language use by comparing two existing and three newly proposed computational models.

The Role of Temporal and Spatial Attention in Size Adaptation

Frontiers in Neuroscience, 2020
One of the most important tasks for the visual system is to construct an internal representation of the spatial properties of objects, including their size.

Revisiting Persistent Neuronal Activity During Covert Spatial Attention

Frontiers in Neural Circuits, 2021
Persistent activity has been observed in the prefrontal cortex (PFC), in particular during the delay periods of visual attention tasks. Classical approaches based on the average activity over multiple trials have revealed that such an activity encodes ...

Spatial attention and the apprehension of spatial relations. [PDF]

Journal of Experimental Psychology: Human Perception and Performance, 1994
Seven experiments examined the role of spatial attention in apprehending spatial relations above, below, left, and right. In Experiment 1, visual search was difficult when targets differed from distractors only in the spatial relation between their elements. Reaction time increased linearly with display size with a slope greater than 60 ms/item.

Visuo-tactile links in covert exogenous spatial attention remap across changes in unseen hand posture [PDF]

, 2002
We investigated the effect of unseen hand posture on cross-modal, visuo-tactile links in covert spatial attention. In Experiment 1, a spatially nonpredictive visual cue was presented to the left or right hemifleld shortly before a tactile target on ...
