<p>An apparatus and method for testing individuals to determine their capability of conducting predetermined tasks. A base line is generated which is unique to each individual to whom the test is to be presented. The individual's current response to the battery of tests is compared by using an algorithm with the individual's base line to determine impairment of the individual. The algorithm is statistically designed to pass individuals relative to their base line performance level while eliminating all false negatives. When an individual tests positive, the test is repeated one or more times and the results compared using an algorithm which is statistically designed to pass individuals relative to their individual base line performance levels while eliminating all false positives. Such is accomplished by providing a source (10) of images randomly and non-repetitively to a screen (14) for recognition and response by the individual being tested. The responses are recorded in a compiler means (18) and then compared to the previous results of the same individual which are stored in a data base (22) and then tabulated to provide an output signal indicative of the individual's present ability to perform the task in question.</p> |
