In a nutshell, van Koningsbruggen and Buonocore's main suggestion is that crowding may be released prior to a saccade because visual attention shifts to the saccade goal before the eyes move.
If processing both images requires visual attention shifts between the two images, then it may be more likely that the images are processed in series.
According to this theory, visual attention shifts to the saccade target and a small number of other objects in its vicinity (perhaps four or fewer) before eye movement is initiated.
However, once goal-influenced top-down processes have an influence on visual attention, adults shift their attention from the unhealthy food to the healthy food or other features on the image, suggesting a self-regulation process of avoidance.
The distribution of drivers' total glance durations on the HMI showed that visual attention was shifted away from monitoring the central road scene towards looking at the in-vehicle display to a considerable extent.
In the Visual Attention Set Shifting task, a horizontal bar consisting of ten squares is permanently presented in the center of the screen.
Errors on the sustained attention dot patterns task, the visual attention set shifting task and the memory search letter task were not associated with affective problems, neither at baseline, nor at follow-up after 2.5 and 5 years (ps > 0.05).
Finally, the relation between affective problems and error rates on the sustained attention dot patterns task, the visual attention set shifting task, and the memory search letter task was tested by correlation; tests were two-sided.
Faster reaction times were associated with higher error rates on the Sustained attention dot patterns task (girls, r = −0.21; boys, r = −0.15; ps < 0.001), indicating an accuracy trade-off, but not on the memory search letter task and visual attention set shifting task (ps > 0.05).
A model based on formal theories of visual attention and attentional set shifting is proposed to account for these effects.
This allows visual attention to be shifted quickly without physically moving the head.
