Orienting of visual attention in aging
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 … WitrynaThe relation between reflexive and voluntary orienting of visual attention was investigated with 4 experiments: a simple detection task, a localization task, a saccade toward the target task, and a target identification task in which discrimination difficulty was manipulated. Endogenous and exogenous orienting cues were presented in …

Witryna7 wrz 2012 · Thus, there is clear evidence to suggest relatively intact visual alerting and visual orienting in older adults; however, the effects and interactions of alerting, orienting, and executive attention using multisensory cues in non-demented older adults and young adults has yet to be reported. 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 ).

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.

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. fidelity money market sweep ratesWitryna18 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. grey ghost gear ugf battle belt reviewWitryna13 sie 2016 · We review findings regarding factors that mediate the impact of aging on orienting, including overt vs. covert attending, exogenous vs. endogenous … fidelity money markets fzdxxWitryna1 gru 2024 · The orienting of spatial attention (Posner, 1980) is a vital cognitive capacity which enables us to prepare to effectively perceive and process information … grey ghost gear smc tall zipper adapterWitrynaVisual search that is based on the observer's expectations (i.e., top-down attention) is relatively preserved as a function of adult age.
