Abstract:

Computerized performance assessment of neurocognitive functioning hasincreased tremendously over the past several years. However, little is known about howwell these measures assess neurocognitive constructs they are purported to evaluate,especially in healthy, non-clinical populations. The Windows Spaceflight Cognitive Assessment Tool WinSCAT is a five-subtest battery derived from the larger Automated Neuropsychological Assessment Metrics ANAM computerized battery for use in evaluation and assessment of spaceflight crew members during space missions. The WinSCAT subtests also have been applied for assessing neurocognitive functioning in clinical populations. Findings indicate the WinSCAT subtests evaluate the cognitive domains of attention, executive functioning, memory, and possibly visuospatial processing. To determine the cognitive content structure of the WinSCAT in healthy non-clinical samples, two studies were performed based on both archival and prospectively-collected data sets. A battery of widely used, traditional clinical neuropsychological tests was administered with the computerized WinSCAT. Bivariate correlation and multiple regression data analyses were utilized to evaluate the extent to which the WinSCAT subtests were associated with specifically-hypothesized cognitive domains. Statistically significant demographic, general ability, and motor functioning variables were covaried to control for their potentially confounding contributions to relationships between the traditional and computerized testing measures. The WinSCAT tasks in the first archival study were found to predict performance on traditionally derived index scores of attention, executive functioning, and memory
