Computerized Test of Attentional Performance (TAP 2.3) - Neglect subtest
Availability
Please visit this website for more information about the instrument: Computerized Test of Attentional Performance – Neglect subtest.
Classification
Exploratory: Unruptured Cerebral Aneurysms and Subarachnoid Hemorrhage (SAH)
Short Description of Instrument
The Test of Attentional Performance is used to evaluate the effectiveness of behavior in everyday activities. Inattentiveness can lead to not noticing important information and difficulties in recalling specific details.
 
Visual field defects are prominent in affected individuals and can lead to serious difficulties in daily activities. The ability to read can be limited by a hemianopsia or a larger defect of the horizontal visual field, especially on the right side. There are two versions of the test; the Visual Field test and the Neglect test.
Comments/Special Instructions
A flicker stimulus is shown at different parts of the screen at varying intervals in order to evaluate vision in areas of the visual field. The individual is focused on the middle of the screen by a specific central task and is required to press a reaction key as soon as possible whenever the stimulus appears.
 
Visual Field test: the peripheral stimulus appears on an empty background.
 
Neglect test: the screen is filled with a mask of numbers in order to provoke extinction.
 
There are several language versions of the test.
 
Administration time: Short version: approx. 5 min, long version: approx. 10 min
Scoring
Outcome variables are percentiles of the reaction time medians of the right and left visual field (T-score right visual field; T-score left visual field).
Rationale/Justification
The Computerized Test of Attentional Performance with its subtest neglect is quick and simple to perform. The available normative data covers broadly the typical age range of patients with SAH. It is available in multiple languages. For these reasons, the Swiss national standard of neuropsychological assessment after SAH includes the Computerized Test of Attentional Performance with its subtest neglect. The test has been used in SAH patients before, but currently no series are published. The test has been used in stroke research, as well as in research on other types of intracranial hemorrhage. Neglect deserves more focus in future studies on outcome after SAH.
