Orienting of visual attention in aging

Witryna27 lip 2010 · Orienting, or the voluntary and involuntary selection of and shifting of attention toward the direction of an incoming stimulus (Posner & Petersen, 1990 ), is associated with activity in the superior and inferior parietal lobes, frontal eye fields, superior colliculus, pulvinar, and reticular thalamic nuclei (Corbetta & Shulman, 2002 … WitrynaAlthough some studies described the apparition of a rightward bias of attention with aging, no study has examined if this bias could be explained by modifications based on age in the mechanisms of attention orienting and, specially, in the cueing effects. 48 participants of different ages were teste …

Witryna27 lut 2024 · Background A widely applied and effective rehabilitation method for patients experiencing spatial neglect after a stroke is “visual exploration training.” Patients improve their ipsilesional bias of attention and orientation by training exploration movements and search strategies toward the contralesional side of space. In this … WitrynaWe examined anticipatory neural dynamics associated with joint spatial-temporal orienting of attention using magnetoencephalography (MEG) in both younger and older adults. Participants performed a cued covert spatial-temporal orienting task requiring the discrimination of a visual target.

WitrynaAttention can be summoned to a spatial location in the absence of an overt orienting response. The reaction time (RT) to a visual target is faster when attention has been drawn to the location of the target by a preceding cue in that location (valid cue) compared with when the cue misdirects attention (invalid cue) away from the location … WitrynaAging may impact orienting through a variety of neurocognitive mechanisms and the interactions between them.

Witryna14 kwi 2024 · Despite the rising global burden of stroke and its socio-economic implications, the neuroimaging predictors of subsequent cognitive impairment are still poorly understood. We address this issue by studying the relationship of white matter integrity assessed within ten days after stroke and patients’ cognitive status one year … WitrynaOrienting involves aligning attention with a source of sensory signals. This may be overt, as in eye movements, or covert, without any movement. Orienting can be manipulated by presenting a cue indicating where in space a person should attend, thereby directing attention to the cued location.

James (1890) probably had a distinction of this sort in mind when he contrasted adjustment of the sensory organs with an internal “anticipatory preparation.” Keywords
