Empirical Development of a Scale for the Prediction of Performance on a SustainedMonitoring Task

摘要

Research on vigilance performance has been extensive, but few guidelines existfor selecting persons well suited to perform vigilance tasks. The focus of this pilot study was to determine if a subset of items from the Minnesota Multiphasic Personality Inventory (MMPI) that would discriminate between soldiers able to sustain an adequate level of performance and soldiers whose performance deteriorated over time could be identified. Thirty-nine items produced chi-squares with p values less than .05. A discriminant analysis correctly classified 88.5% of the soldiers maintaining their performance rate and 83.9% of the soldiers with performance degraded over time. If validation efforts are successful, it may be possible to use the 39-item scale to select soldiers who will, on average, detect 13% more targets and incorrectly identify 15% fewer targets.
