Lateralized spatial biases after brain damage are commonly assessed using batteries of paper-and-pencil tests. These tests hardly allow quantification of performance in different locations in space, and they tend to lose sensitivity along the course of recovery. We tested the dynamic Starry Night Test (SNT), a novel computerized test measuring reaction time and detection accuracy for visual target stimuli in a dynamic background, in 32 inpatients with right hemisphere stroke (RHS), 16 patients…

Spatio-Temporal Features of Visual Exploration in Unilaterally Brain-Damaged Subjects with or without Neglect: Results from a Touchscreen Test
TLDR
The proposed touchscreen-based assessment had evidenced disorders in spatial exploration also in patients without clinically diagnosed USN.

TLDR
Not only the presence but also the time course of hemispatial neglect strongly depends on the degree of attentional engagement required by the task, so the hypothesis that the putative early resolution of neglect might be due to the insensitivity of testing methods rather than to the lack of spontaneous recovery at later stages is tested.
Interaction between spatial neglect and attention deficit in patients with right hemisphere damage
The Ipsilesional Attention Bias in Right-Hemisphere Stroke Patients as Revealed by a Realistic Visual Search Task: Neuroanatomical Correlates and Functional Relevance
Objective: Right-hemisphere stroke may cause an ipsilesional attention bias and left hemispatial neglect. Computerized time-limited tasks are more sensitive than conventional paper–pencil tests in…
Assessment of spatial neglect using computerised feature and conjunction visual search tasks
TLDR
It is proposed that computerised assessment of visual search capacity is a useful and sensitive adjunct to standard paper-and-pencil tests of USN, with the advantage of testing responses based on attention shifts under a time constraint.
Deficits of contralesional awareness: a case study on what paper-and-pencil tests neglect.
TLDR
The results confirm the well-known lack of sensitivity of standard neuropsychological tests to detect subclinical forms of neglect, which, nonetheless, may result in negative consequences in everyday life.
Dual-Task in Large Perceptual Space Reveals Subclinical Hemispatial Neglect
TLDR
It is suggested that dual-tasks presented on a large screen sensitively reveal subclinical neglect in stroke, and new, sensitive, and ecologically valid methods are needed to evaluate sub clinical neglect.

Not Just Language: Persisting Lateralized Visuospatial Impairment after Left Hemisphere Stroke
TLDR
The observation of significant leftward visuospatial bias in this chronic stroke group provides further evidence that the left hemisphere also plays a role in the balance of visual attention across space.

Sensitivity of clinical and behavioural tests of spatial neglect after right hemisphere stroke
TLDR
The results of this study support the assumption that neglect is a heterogeneous disorder and that behavioural assessment of neglect in daily life was more sensitive than any single paper and pencil test.
Development of a behavioral test of visuospatial neglect.
TLDR
The Rivermead Behavioral Inattention Test appears to be a valid and reliable test of visuospatial neglect and one which is likely to provide more information about everyday problems than existing measures of neglect.

The spatial distribution of visual attention in hemineglect and extinction patients.
TLDR
Patients with left hemineglect or extinction resulting from right hemisphere vascular lesions and in brain-damaged and healthy control subjects showed a greater impairment in both the speed of response and the detection rate in the contralesional than in the ipsilesional hemifield, suggesting abnormalities in these processes are likely to be related to abnormal automatic processes rather than controlled attention.
Using Reaction Time to Assess Patients With Unilateral Neglect and Extinction
TLDR
In order to illustrate how reaction time measures can be used to examine the subtleties of visuo-spatial deficits, several reaction time studies that have been conducted in patients with neglect and/or extinction are discussed.

Factors affecting the clinical measurement of visuo-spatial neglect.
TLDR
The large cluster, including a variety of tests of extra personal neglect, together with the study of single cases, suggests the possibility of differentiating the various manifestations of spatial neglect which can be interpreted on the basis of the descriptions of other individual cases previously reported in the literature.
