The Response Analysis Tester ( Rater ) and Logical

This report presents additional, normative data for the Response Analysis Tester (RATER), a performance testing instrument, using geometric forms as stimuli. The results showed that somewhat higher scores were obtained with the geometric form stimuli than had been previously obtained using color stimuli. Examination of RATER scores as related to the Navy Basic Test Battery showed the only significant relationship to be between RATER scores and the CLER portion for men in non-technical rates only. A second part reports the results obtained using the Logical Inference Tester (LOGIT) in a study to determine the effects of flashing light stress on performance. It was found that for two, pre-trained subjects no significant decrements in performance (number of errors) resulted from the addition of the flashing light while performing the test. The additional experience with these two performance measuring instruments has resulted in increased confidence in their usefulness. The data presented add to the cumulative data being collected and will augment base-line data available against which decrement-inducing studies can be compared.
