The Capacity of Visual Short-Term Memory is Set Both by Visual Information Load and by Number of Objects
The greater the information load of each item in a stimulus class (as indicated by a slower search rate), the fewer items one can hold in memory.
The Spatial Resolution of Visual Attention
The results suggest that the parietal area is the most likely locus of this selection mechanism and that it acts by pointing to the spatial coordinates (or cortical coordinates) of items of interest rather than by holding a representation of the items themselves.
Attention-based motion perception.

Two "attentive" tracking tasks reveal the existence of an attention-based motion process that is "low-level" or automatic in that it signals motion even in the absence of attention to the stimulus, and one that is mediated by attention to visible features and provides accurate velocity judgments independently of the features being tracked.
Retinotopy and color sensitivity in human visual cortical area V8

The location of the human color-selective region did not match the location of area V4 (neither its dorsal nor ventral subdivisions), as extrapolated from macaque maps, and instead this region coincides with a new retinotopic area that is called 'V8', which includes a distinct representation of the fovea and both upper and lower visual fields.

The results support the view that attentional orienting underlies distortions in perceived duration, and show that TSE in the visual domain can occur because of semantic novelty, rather than image novelty per se.
Attentional resolution and the locus of visual awareness
It is suggested that the attentional filter acts in one or more higher visual cortical areas to restrict the availability of visual information to conscious awareness to limit the resolving power of attention.
Independent Resources for Attentional Tracking in the Left and Right Visual Hemifields
This finding places broad constraints on the anatomy and mechanisms of attentive tracking, ruling out a single attentional focus, even one that moves quickly from target to target.
Cortical fMRI activation produced by attentive tracking of moving targets.

FMRI results suggest that attentive tracking is mediated by a network of areas that includes parietal and frontal regions responsible for attention shifts and eye movements and the MT complex, thought to be responsible for motion perception.
Predictive remapping of attention across eye movements

It is found that, briefly before the eyes start moving, attention drawn to the targets of upcoming saccades also shifted to those retinal locations that the targets would cover once the eyes had moved, facilitating future movements.
Tracking multiple targets with multifocal attention
This research has implications for computer vision, where there is a growing demand for multiple-object tracking and properties defining a 'trackable' target, the maximum number of targets that can be tracked, and the hemifield independence of the tracking process are identified.
