There are suggestions in the literature that spatial precuing of attention with peripheral and central cues may be mediated by different mechanisms. To investigate this issue, data from two previous papers were reanalysed to investigate the complete time course of precuing target location with either: (1) a peripheral cue that may draw attention reflexively, or (2) a central, symbolic cue that may require attention to be directed voluntarily. This analysis led to predictions that were tested in…

Importance of precue location in directing attention.
Visual orienting with central and peripheral precues: Deconfounding the contributions of cue eccentricity, cue discrimination and spatial correspondence
TLDR
Results show that the need to discriminate between cue stimuli, and the visual eccentricity of cues, are not critical factors mediating attentional effects of spatial precues, however, the presence or absence of spatial correspondence between the location of a cue stimulus and the locations of the target was critically important.
The effects of implicit attentional learning and habituation on inhibition of return
TLDR
Although the initiation of IOR is embedded in motor areas, the con-sequences of the inhibition have been found to be mostly attentional when IOR was stimulus-induced (Hunt & King-stone, 2003).
A Framework for Understanding the Allocation of Attention in Location-Precued Discrimination
The effects of attention on visual perception are assessed in the location-precuing paradigm. First, we present a review of some current metaphors for attention and relevant data. Then, a framework

TLDR
The external noise paradigm was applied to investigate mechanisms of spatial attention in location precuing, and a perceptual template model identified different mechanisms of attention for central and peripheral precuing and a combination of external noise exclusion and stimulus enhancement for peripheral cuing.
Unmasking the inhibition of return phenomenon
TLDR
It is reported that lOR occurs at a cued location far earlier than was previously thought, and that it is distinct from attentional orienting.
Timing of facilitatory and inhibitory effects of visual attention
TLDR
The data allowed the conclusion that a shorter range of precue-to-target delays results in later onset of IOR than does a longer range of delays to be concluded.
Unmasking the inhibition of return phenomenon
TLDR
This work reports that IOR occurs at a cued location far earlier than was previously thought, and that it is distinct from attentional orienting, and concludes that previous failures to observe early IOR at acued location may have been due to attention being directed to the cuing location and thus “masking” IOR.

TLDR
Results suggest that attention shifting is not analogous to a constant-velocity moving spotlight, and there were no differences in accuracy as a function of eccentricity for most SOAs.
How Quickly Can Attention Affect Form Perception
Abstract : It is possible to attend to different locations in the visual field without changing fixation. Recently, some researchers have suggested that sequenced of such internal attention shifts
Saccade preparation inhibits reorienting to recently attended locations.
TLDR
Manual reaction time in normal human subjects is measured to confirm that an eccentric visual signal has a biphasic effect on covert attention and eye movements and activation of return is activated by midbrain oculomotor pathways and may function as a location "tagging" mechanism to optimize efficiency of visual search.

TLDR
The results from these experiments suggest that discrimination of line orientation benefits less from focal attention than doesdiscrimination of line arrangement, but that both discriminations suffer when attention must be disengaged from an irrelevant spatial location.
Visual attention modulates signal detectability.
TLDR
Findings indicate that visual-spatial attention facilitates the processing of sensory input during detection either by increasing sensory gain for inputs at cued locations or by prioritizing theprocessing of cued inputs.

TLDR
Investigation of the visually allocated "beam" studied by Posner and others showed that orienting attention in response to central cues showed similar effects for both conjunction and feature search, but when attention was oriented with peripheral visual cues, conjunction search showed larger effects of attention than did feature search.
