TLDR
In this article, the effects of practice on the early facilitation and later inhibition of return (IOR) effects of cueing in detection and color-discrimination tasks were examined, and it was shown that cueing effects were more positive in the discrimination task than in the detection task.Abstract:
We report two experiments that examine the effects of practice on the early facilitation and later inhibition of return (IOR) effects of cueing in detection and color-discrimination tasks. In the first experiment a short and a long SOA were mixed within a block of trials, so that there was temporal uncertainty. In the second experiment SOA was manipulated between subjects, to eliminate temporal uncertainty. Facilitation and IOR effects were obtained in the short and long SOAs respectively, in both detection and discrimination tasks, and they consistently decreased with practice. The cueing effects were more positive (i.e., bigger facilitation and smaller IOR) in the discrimination task than in the detection task. Cueing and practice effects were modulated by temporal uncertainty (Experiment 1 vs. Experiment 2). Our results go some way to resolving some of the contradictory findings in the literature.read more

The Spatial Orienting paradigm: how to design and interpret spatial attention experiments.
TL;DR: This review attempts to describe, the Spatial Orienting paradigm for the naïf reader, and explains in detail when is it used, which variables are usually manipulated, how to interpret its results, and how can it be adapted to different populations and methodologies.

Dorsal and Ventral Parietal Contributions to Spatial Orienting in the Human Brain
TL;DR: For the first time causal evidence of right intraparietal sulcus involvement in both types of attentional orienting is provided, and the temporoparietal junction is linked with the orienting of exogenous but not endogenous spatial attention.

TL;DR: It is concluded that IOR with manual responses relies on fronto-parietal attentional networks in the right hemisphere, whose functioning is typically impaired in neglect patients, and saccadic IOR may instead depend on circuits less likely to be damaged in neglect, such as the retinotectal visual pathway.
Journal ArticleDOI
The phenomenology of endogenous orienting
TL;DR: It is concluded that endogenous orienting with peripheral cues can occur independently of participants developing explicit hypotheses about the cue-target relationships.

Two mechanisms underlying inhibition of return
TL;DR: It is demonstrated that when the eyes moved to the peripheral cue and back to centre before the target appeared (to generate the motoric flavour), IOR was observed in detection tasks, but not in colour discrimination tasks, for which the outcome of a non-spatial perceptual discrimination is reported.

Orienting of attention
TL;DR: This paper explores one aspect of cognition through the use of a simple model task in which human subjects are asked to commit attention to a position in visual space other than fixation by orienting a covert mechanism that seems sufficiently time locked to external events that its trajectory can be traced across the visual field in terms of momentary changes in the efficiency of detecting stimuli.

Inhibition of return.
TL;DR: In more complex organisms more complex systems have evolved to orient the various receptors either towards or away from signal sources in the environment and to prepare the organism to select from arepertoire of behavioral actions as discussed by the authors.

Inhibition of return : Neural basis and function
TL;DR: Reports are reported on studies in patients and normals which demonstrate the relationship of this component to neural systems which generate saccades and the tendency to inhibit orienting towards visual locations which have been previously attended.

Shifting visual attention between objects and locations: evidence from normal and parietal lesion subjects.
TL;DR: In this article, the authors examined both space-and object-based attention components in neurologically normal and parietal lesion subjects, who detected a luminance change at 1 of 4 ends of 2 outline rectangles.
