Although 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 tested with a spatial cueing …
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 … Witryna9 lis 2024 · Spatial and temporal expectations act synergistically to facilitate visual perception. In the current study, we sought to investigate the anticipatory oscillatory markers of combined spatial-temporal orienting and to test whether these decline with ageing. We examined anticipatory neural dynamics associated with joint spatial …
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 … 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 …
Witryna9 maj 2016 · With respect to orienting of visual attention, researchers have also observed increased amplitude of posterior negativity beginning approximately 100 ms following validly cued target stimuli ( Harter et al., 1989; Hopf and Mangun, 2000; Nobre et al., 2000; Talsma et al., 2005 ).

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 dr thomas j montgomery lafayette laWitrynaOrienting 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. dr. thomas john md ophthalmologistWitryna18 lip 2014 · Cueing effects in a condition that for the first time isolated voluntary orienting (predictive number cues) with older adults were significant, and comparable to effects for younger adults, demonstrating that older adults successfully utilize cues to direct their spatial attention strategically. dr thomas john flcolumbia county superior courtWitrynaAlthough 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 … columbia county stop dwi
