Spatial Attention

Spatial attention is the cognitive process of selectively prioritizing information from particular locations while reducing attention to competing stimuli. It can operate with or without moving the eyes: top-down signals from attention networks bias sensory processing toward a selected region, while incoming visual, auditory, or tactile signals provide spatial information. In medicine, spatial attention is relevant to assessing stroke-related hemispatial neglect, traumatic brain injury, neurodegenerative disease, and developmental disorders. Measuring responses to targets across space can reveal impaired orienting and guide rehabilitation, helping researchers link behavior with brain function and evaluate recovery.

Measurement of Neurophysiological Signals of Ignoring and Attending Processes in Attention Control

2015

Attention control comprises enhancement of target signals and attenuation of distractor signals. We describe an approach to measure separately but concurrently, the neurophysiology of attending and ignoring in sustained intermodal attention, utilizing a passive control condition during which neither process is continuously engaged.

Visual Attention: fMRI Investigation of Object-based Attentional Control

Source: Laboratories of Jonas T. Kaplan and Sarah I. Gimbel— University of Southern California The human visual system is incredibly sophisticated and capable of processing large amounts of information very quickly. However, the brain's capacity to process information is not an unlimited resource. Attention, the ability to selectively process information that is relevant to current goals and to ignore information that is not, is therefore an essential part of visual perception. Some aspects of...

The Attentional Blink

Source: Laboratory of Jonathan Flombaum—Johns Hopkins University In order for recognition of a certain stimulus to take place, visual attention needs to be directed towards said stimulus. To the earliest parts of the visual system, objects are not objects, they are collections of visual features-lines, corners, changes in texture, color, and light. Attention is the resource that is necessary for later processing in order to recognize what a given bundle of features adds up to. This makes...

Spatial Cueing

Source: Laboratory of Jonathan Flombaum—Johns Hopkins University Attention refers to the limited human ability to select some information for processing at the expense of other stimuli in the environment. Attention operates in all sensory modalities: vision, hearing, touch, even taste and smell. It is most often studied in the visual domain though. A common way to study visual attention is with a spatial cueing paradigm. This paradigm allows researchers to measure the consequences of focusing...
