attentional shift
shift of attention

Results were in agreement that covert and overt attentional shifts engage the same neural mechanisms.

This attentional shift causes the encoding of information to occur near the saccade target location.

While the type of attentional shift corresponds to different brain areas being activated, there is a lot of overlap seen.

Attentional shift occurs across modalities and depends on all of these properties to divide attention in order to most efficiently process information.

In order to perform a successful and accurate saccade an individual is required to make an attentional shift to the saccadic target.

Formulated by Michael Posner, the task assesses an individual's ability to perform an attentional shift.

While these studies may agree on the areas, they are not always in agreement on whether an overt or covert attentional shift causes more activation.

It has also been shown that lesions of the locus coeruleus (LC) impair this attentional shift.

Hence, there are two types of attention, distinguished in terms of the effort involved in their use and their changes in attentional shift:

Current research in visual neuroscience and psychophysics is investigating how microsaccades relate to fixation correction, control of binocular fixation disparity and attentional shifts.

DF did not exhibit the usual advantage for within- over between-object attentional shifts or figure comparisons, a clear indicator of the absence of normal object-based attentional effects.

Lamy and Egeth found object-based attentional effects when attentional shifts during tasks were required, but no attentional effects when the shifts were not required.

In one well known experiment of attention that examines the attentional shift, the Posner Cueing Task uses a 2AFC design to present two stimuli representing two given locations.

Attentional shift (or shift of attention) occurs when directing attention to a point to increase the efficiency of processing that point and includes inhibition to decrease attentional resources to unwanted or irrelevant inputs.

Properties of attention resources used depend on whether it is endogenously or exogenously directed or whether attention occurs as a spotlight or gradient, affect attentional shift as well as switching costs that may be experienced.

More generally, the N2 component has been described in tasks that reflect stimulus identification, attentional shifts, inhibition of motor responses, overcoming stereotypical responses or conflict monitoring, maintenance of context information, response selection timing, and detection of novelty or mismatch.

Rapid shifting of attention can push the limit to about ten.

Kira didn't look up at him, but he must have sensed her shift of attention.

Then there was a small stir in the crowd; a rustle, a shifting of attention.

Multitasking, he said, entails the rapid shifting of attention from one thing to the next.

In conclusion, many neural mechanisms are involved in shifts of attention.

The economy had slowed, and a shift of attention to the northern end of town left older hotels, such as the Cabana, struggling.

Additionally, this study reported that covert shifts of attention showed greater activity levels than in the overt attention condition.

These are all issues the Democrats regard as election-winners, and a shift of attention back to the social issues could imperil this strategy.

This constant shifting of attention between two artistic worlds keeps you in a state of perceptual anxiety.

Shifting of attention is needed to allocate attentional resources to more efficiently process information from a stimulus .

Although these differences did exist, overall there was a lot of overlap demonstrated for voluntary and reflexive shifts of attention.

Rosen et al.'s study found a fair amount of overlap between endogenous and exogenous shifts of attention.

The disorder is associated with bilateral damage to the parietal lobe, an area of the brain linked with spatial shifts of attention.

However, this study differed in that overt shifts of attention showed greater activation in these neural areas, and this occurred even at multiple shift rates.

Effortful control includes the focusing and shifting of attention, inhibitory control, perceptual sensitivity, and a low threshold for pleasure.

This view is also accompanying a more general scholarly shift of attention from absolute certainties to possibilities, from known masterpieces to alluring sidebars.

Another theory to account for simultanagnosia involves deficits in "attentional disengaging," and this impairment affects shifts of attention in any direction.

These neuropsychological results are consistent with the view that the process of counting, but not that of subitizing, requires active shifts of attention.

Mrs. Buttafuoco, who wanted at all costs to protect her husband from criminal charges, was outraged at the sudden shift of attention to her own family today.

Rodriguez, V. and Valdes-Sosa, M.Sensory suppression during shifts of attention between surfaces in transparent motion.

One should question whether this additional activation has to do with the selected task for the covert condition, or rather if it is specific to a covert shift of attention.

A ridiculously haughty snort made Kira turn, and Rom took her shift of attention as some sort of invitation to stump through the piles of litter and join them.

It is not entirely clear how this works, although it is thought that the unconscious shift of attention or focus caused by the intense stimulation of the vestibular system temporarily influences awareness.

"Move α" marks a shift of attention in transformational grammar in around 1980, away from focussing on specific rules (the only "rule" is "Move α") to "Principles" constraining them.

A Shift of Attention One reason China may be going ahead with the trials now is that it believes that the international outrage over the killings in Tiananmen Square has simmered down.
