A peripheral visual cue in an empty field (1) often summons head or eyes, or both, (2) improves efficiency at the cued position while attention is directed to it, even without overt movements, and (3) reduces processing efficiency at the cued position once attention is withdrawn. We have studied the time course and the effects of mid-brain and cortical damage on these components of orienting. The facilitation arises from shifts in covert attention. In cases of mid-brain degeneration due to… Expand
Orienting attention to instants in time

TLDR
The findings show that the temporal framework can be used to guide selective attention selectively to different points in time, enhancing behavioral performance and illustrating the flexibility of attentional functions in the human brain. Expand
Cortical activity time locked to the shift and maintenance of spatial attention.
TLDR
It is concluded that maps of prioritized locations are represented in areas classically associated with oculomotor control, and the readout of these spatial maps by posterior visual areas directs spatial attention just as the read out by downstream saccade generators directs saccades. Expand
The Frontal Cortex and Exogenous Attentional Orienting
TLDR
The results suggest that the dorsolateral prefrontal cortex plays an important role in exogenous orienting and that component processes of this system may be differentially impaired by damage to different parts of the dorsal prefrontal cortex. Expand
Disruption of Reflexive Attention and Eye Movements in an Individual with a Collicular Lesion
TLDR
The unequal disruption of voluntary and reflexive eye movements supports the idea that oculomotor responses can be generated in an independent fashion by frontal cortical and lower level neural systems. Expand
Influences of lesions of parietal cortex on visual spatial attention in humans
TLDR
Testing elements of visual attentional processing in patients with parietal, frontal, or temporal lesions and compared their responses to control subjects demonstrates a further deficit in a cued reaction-time task suggesting abnormal visual attention. Expand
Covert Orienting of Attention in the Rat and the Role of Striatal Dopamine
TLDR
Findings add additional support to the hypothesis that the deficit that appears as hemineglect observed after striatal damage reflects a motor impairment rather than damage in neural systems underlying mechanisms for directing attention. Expand
Modulating the attentional bias in unilateral neglect: the effects of the strategic set
TLDR
Three experiments tested the hypothesis that attentional bias in neglect involves primarily exogenous, or stimulus-based, orienting of attention, with relatively preserved endogenous, or voluntary, orientation, and suggest that endogenous orienting is relatively spared, if slowed, in unilateral neglect. Expand
Neural Processes Involved in Directing Attention
TLDR
Boys appeared more aroused and reflected faster and greater selective processing than girls than girls and the effects of spatial attention on P1, N1, and P3 ERP components following the targets replicated previous results. Expand
Neural correlates of spatial orienting in the human superior colliculus.
TLDR
Using an optimized oculomotor paradigm together with high-field, high-spatial resolution functional magnetic resonance imaging and high-speed eye tracking, it is demonstrated that BOLD signal changes recorded from the human SC correlate strongly with saccadic measures of AC and IOR. Expand
Impaired stimulus-driven orienting of attention and preserved goal-directed orienting of attention in unilateral visual neglect.
TLDR
A patient who shows a left neglect in normal reading and line bisection but an intact ability to locate the left end of the stimulus is described, suggesting his neglect is due largely to an impairment of the mechanism mediating automatic, stimulus-driven orienting of attention. Expand

Dissociation of spatial information for stimulus localization and the control of attention.
TLDR
Evidence is provided that following callosal surgery, a bilateral representation of the visual world is available for the allocation of attentional capacities, and that a distinction can be made between spatial information as it is used for the control of attention and that used for explicit stimulus localization.

Orienting of Attention*
  • M. Posner
  • Psychology, Medicine
  • The Quarterly journal of experimental psychology
  • 1980
TLDR
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. Expand
Moving attention through visual space.
TLDR
Support is provided for an analogue movement of attention across the visual field that does not involve the suppression found during saccades by reports that these shifts of attention can be time locked to a central cue. Expand
Enhancement of perceptual sensitivity as the result of selectively attending to spatial locations
TLDR
The hypothesis that selective attention can enhance perceptual sensitivity can be supported, as well as theories of attention, such as “perceptual tuning, ” that suggest very early selective control. Expand

TLDR
The results of these experiments support the contention that the mechanisms that shift attention are separate from those that control saccadic eye movements, and implication for theories of saccades suppression is discussed. Expand

During voluntary movements hand and eye are coordinated under the control of central attentional mechanisms. Several techniques are reviewed that serve to dissociate the usually coordinate activityExpand
Brain Mechanisms for Directed Attention

  • Journal of the Royal Society of Medicine

TLDR
Professor Mountcastle has shown just how useful the techniques of clinical and experimental psychology can be, even in the seemingly unpromising field of animal experiment, where intercommunication is minimal and behaviour rather than speech is the touchstone. Expand
A feature-integration theory of attention
TLDR
A new hypothesis about the role of focused attention is proposed, which offers a new set of criteria for distinguishing separable from integral features and a new rationale for predicting which tasks will show attention limits and which will not. Expand
Varieties of Residual Experience*
  • L. Weiskrantz
  • Psychology, Medicine
  • The Quarterly journal of experimental psychology
  • 1980
TLDR
Preliminary evidence is presented on the incidence of “blind-sight” and related aspects of residual function, including examination of different dimensions such as form, detection, movement, orientation, and spatial localisation within field defects. Expand
Mental imagery and the third dimension.
  • S. Pinker
  • Psychology, Medicine
  • Journal of experimental psychology. General
  • 1980
TLDR
The time subjects took to scan between objects in a mental image was used to infer the sorts of geometric information that images preserve, and it is argued that imagery and perception share some representational structures but that mental image scanning is a process distinct from eye movements or eye-movement commands.
