BACKGROUND Most aspects of attention-deficit/hyperactivity disorder diagnosis rely on subjective judgment. Computerized continuous performance tests are designed to improve the validity of the process but are controversial due to low odds ratios. There is a need to find more definitive measures of assessment. OBJECTIVES To test the validity and reliability of a new tool, a computerized contin...

OBJECTIVE This study compared the relationship between computer experience and performance on computerized cognitive tests and a traditional paper-and-pencil cognitive test in a sample of older adults (N = 634). METHOD Participants completed computer experience and computer attitudes questionnaires, three computerized cognitive tests (Useful Field of View (UFOV) Test, Road Sign Test, and Stro...

CONTEXT Computer-based neurocognitive assessment programs commonly are used to assist in concussion diagnosis and management. These tests have been adopted readily by many clinicians based on existing test-retest reliability data provided by test developers. OBJECTIVE To examine the test-retest reliability of 3 commercially available computer-based neurocognitive assessments using clinically ...

The scrambled sentences test (SST), an experimental procedure that involves participants writing down their cognitions, has been used to elicit individual differences in depressiveness and vulnerability to depression. We describe here a modification of the SST to adapt it to computerized administration, with a particular view of its use in large samples and functional neuroimaging applications....

An automated, computerized color-vision test was designed to diagnose congenital red-green color-vision defects. The observer viewed a yellow appearing CRT screen. The principle was to measure increment thresholds for three different chromaticities, the background yellow, a red, and a green chromaticity. Spatial and temporal parameters were chosen to favor parvocellular pathway mediation of thr...

Neurobehavioral testing provides for noninvasive assessment of the functional integrity of the nervous system. Neurobehavioral tests have been used as quantitative outcome measures in a number of epidemiologic investigations of the potential effects on the nervous system from exposure to organic solvents, heavy metals, and pesticides. Because of the functional complexity of the nervous system, ...

A word completion priming test was used to differentiate between normal student control subjects and students instructed to malinger. Controls (n = 60) were instructed to do their best, while malingering subjects (n = 60) were instructed to fake a memory deficit for credit and possible financial compensation. Subjects initially rated and completed stems for words that had at least 10 possible c...
