Other examples of such benefits from between-trial consistency for visual attention include probability cueing of location [19], [20], where target detection is faster at locations where a target is more likely to appear than in other locations, perceptual learning [21], [22] contextual cueing [23] and statistical learning [24].
Figure 4 shows attention-related modulations (ARMs), isolated by contrasting activations from bimodal visual attention blocks with activations from bimodal auditory attention blocks.
However, results from the visual attention task indicated a dose-dependent reduction in the performance of fluoxetine-treated males, whereas fluoxetine-treated females tended to improve over baseline.
Yet, he noted the limitation that moving images make comparative analyses difficult, as the information disappears from our visual attention and cannot be revisited (Neurath 1945/1973, 238).
However, it might also result from reduced visual attention that would be expected to affect the early cortical responses in occipital and occipitotemporal cortex.
Results from the visual attention task (NEPSY) did not show differences between the groups of children (P = 0.28) when subjects were exposed to an attention task excluding the demanding integration of visual and motor capabilities.
Although it differs from the visual attention task (NEPSY) in terms of differences between the groups, the parents' ratings of children's attention problems (CBCL) further support the validity of our findings.
While more work remains to be done to further characterize the proposed mechanisms behaviorally and shed light on its neural implementation, our current results provide the first strong evidence for the existence of a visuomotor binding mechanism that is dissociable from general visual attention.
But only by analyzing Slow Potentials (SPs) from a simpler visual attention task we began to consider that this variability may be inherent to cortical physiology [2].
The right PPC stimulation site was selected based on fMRI results from a classic visual attention study by Hopfinger et al. (2000) that reported possible involvement of this site in top down attentional modulation of visual processing.
