Abstract
A battery of behavioral tests was developed, based on human information processing functions, with application in clinical and research screening and diagnosis for health hazards evaluations. Test equipment was programmed for test presentation and collection, storage, and preliminary analyses of data for eight tests, and consisted of three microprocessor systems. The test battery included tasks to measure processing level, choice reaction time, short term memory, motor response, stimulus classification, color and word selective attention, memory scanning, and visual search. To measure the sensitivity of the test battery, three groups of subjects were given alcohol to produce blood alcohol concentrations (BAC) of 0, 0.05, or 0.10 percent, and then administered the test battery. Individual subtests did not reflect BAC performance differences as effectively as the test battery as a whole, and some subtests were more sensitive than others. Perceptual and motor tasks were the most sensitive to alcohol effects, cognitive tasks were intermediate, and the remaining tasks were less sensitive. The author concludes that the test battery generally was sensitive to the effects of alcohol, but failed to discriminate between subjects at different BAC levels and recommends that the sensitivity and reliability of the battery to other toxic substances be investigated.
