Seventy-five left and right brain-damaged patients, with or without hemispatial neglect, and 40 age-matched control subjects were tested on cancellation tasks with two different visual textures modeled after Julesz (1981). In one condition ("preattentive"), target elements segregated easily from background elements and were perceived effortlessly. In the other ("attentive"), target elements did not segregate easily and could be detected only after prolonged focal scrutiny. Both controls and… Expand
Effects of attentional and cognitive variables on unilateral spatial neglect
TLDR
The worse performance of patients without neglect in the 'multiples of 3' task is consistent with the evidence that right-hemisphere lesions per se impair the ability to maintain attention, and suggests that the exacerbation of neglect during execution of a demanding, non-spatial, cognitive task might be explained by a deficit of sustained attention in addition to a selective deficit of spatial attention.

Hemispatial Neglect and Visual Search: A Large Scale Analysis
TLDR
Patients with brain-damage with or without accompanying neglect were impaired at searching for the contralateral target on both forms of visual search, relative to normal control subjects, although this deficit was magnified in individuals with neglect and was also exacerbated by the presence of hemianopia. Expand
Local (focussed) and global (distributed) visual processing in hemispatial neglect
TLDR
Observations indicate that focussed and distributed components of visual attentional processing may be differentially affected in left and right brain-damaged patients with and without neglect. Expand
Preattentive and Attentive Visual Search in Individuals With Hemispatial Neglect
Preattentive and attentive visual processing was examined in patients with hemispatial neglect, hemispatial neglect with hemianopia, and control participants. In the preattentive search task, targetsExpand
Preattentive and attentive visual search in individuals with hemispatial neglect.
TLDR
This study demonstrates preserved explicit detection of visual features in cases of hemispatial neglect by showing that neglect patients were characteristically impaired in the contralesional field in the attentive search task. Expand
Prism Adaptation and Spatial Attention: A Study of Visual Search in Normals and Patients with Unilateral Neglect
TLDR
It is suggested that the perceptual aftereffects in normals and amelioration of unilateral neglect following prism adaptation are not mediated by an adaptive redistribution of spatial attention. Expand
Manual responses and saccades in chronic and recovered hemispatial neglect: a study using visual search
TLDR
The measurement of saccades allowed the task to be fractionated, and thus, reveal the action of multiple mechanisms controlling saccade programming and manual reaction times in search. Expand
Probability Cuing of Target Location Facilitates Visual Search Implicitly in Normal Participants and Patients with Hemispatial Neglect
TLDR
The results suggest that attentional orientation and sensitivity to external probabilities are possibly dissociable and an early sensory and a late motor mechanism are postulated as possibly being involved in the observed probability-matching behavior of participants. Expand
Emotional processing and its impact on unilateral neglect and extinction
TLDR
Findings suggest that emotionally significant information is not only extracted from stimuli at neglected locations through spared pathways, but can also induce emotional biases in attention that partly counteract the abnormal spatial biases caused by fronto-parietal damage. Expand
First Saccades Reveal Biases in Recovered Neglect
TLDR
It is concluded that eye movement patterns are far more susceptible to remaining spatial impairments and can thus provide a sensitive means to assess the extent of neglect recovery. Expand

Selective attention in hemispatial neglect.
TLDR
It is indicated that increasing demands on visual selective attention adversely affect both exploration of the left side of space and visual discrimination. Expand
Preattentive Processes Guide Visual Search: Evidence from Patients with Unilateral Visual Neglect
TLDR
It is suggested that flanking stimuli on the neglected contralesional side of visual space can influence the reference frame by grouping with task-relevant stimuli, and that this preattentive influence can be preserved in patients with unilateral visual neglect. Expand
Perceptual and Action Systems in Unilateral Visual Neglect
In this chapter we review three different accounts of unilateral neglect: one maintaining that neglect is due to early visual processing deficits; one maintaining that neglect is due to a disorder ofExpand
The Deployment of Visual Attention in the Intact Field of Hemineglect Patients
TLDR
Patients with left hemispatial neglect afterright hemisphere lesions and control patients with right hemisphere lesions were presented in the ipsilesional visual field with stimuli that could occupy left-right relative positions and reaction times and measures of sensitivity and response bias were obtained. Expand
Attentional Shift Towards the Rightmost Stimuli in Patients with Left Visual Neglect
TLDR
In a search task, right brain-damaged patients with visual neglect showed the fastest response when the target was at the rightmost position and progressively slower responses as it moved towards the center of the display. Expand
Cortical substrates supporting visual search in humans.
TLDR
The contralateral deficit was evident in all patient groups, supporting the notion that dorsolateral frontal as well as posterior parietal and temporal-parietal cortex plays a critical role in visual spatial attention. Expand
Contralateral and ipsilateral disorders of visual attention in patients with unilateral brain damage.
TLDR
The alternative hypothesis viewing ipsilateral disorders as resulting from a widespread lowering of general attention (and only contralateral neglect reflecting a specific disorder of visual attention) was supported by results obtained on a verbal memory test, used to evaluate the general cognitive and attention level of the patients. Expand
Hemispheric contribution to exploration of space through the visual and tactile modality.
TLDR
Control and unilaterally brain-damaged patients were given two tests requiring the exploration of space through the visual and the tactile modalities and this finding lends support to the hypothesis that hemi-inattention does not depend so much on perceptual and motor factors as on a mutilated representation of space. Expand
Visual searching in normal and brain-damaged subjects (contribution to the study of unilateral inattention).
TLDR
The authors particularly stress the importance of oculo-motor imbalance deviating the axis of the gaze to the right, which is linked to age and independent of the socio-cultural level. Expand
Early orientation of attention toward the half space ipsilateral to the lesion in patients with unilateral brain damage.
TLDR
Results consistently showed that patients with right brain damage tend to orient attention automatically toward the ipsilateral half space more than patients with left brain damage, consistent with the hypothesis that hemi-neglect is a multi-component syndrome with an early orienting of attention toward the half space ipsilaterally to the lesion as the first of these components.
