Abstract
Individual differences in perception have drawn increased attention from training and task-performance communities. If perceptual tests are to be utilized to train, predict, or optimize performance, then they need to be studied and evaluated as differential measures. In this study, the reliability and individual differences for a perceptual test battery (seven tasks) were investigated. The participants (10 males, 11 females) completed five trials of the test battery within a ten day span. In general, the results of this study are positive. Six of the seven tasks showed sizable individual differences and four of the seven were reliable. The three tasks that showed unreliability have since been modified and need to be formally studied.
