Method and apparatus for testing human performance by measuring ability to employ job-related skills in an environment requiring skill switching in the presence of a forced attention shift. A human operator is tested by use of a monitor display upon which are presented an alternating sequence of primary tasks requiring utilization of different skills. A keyboard and a joy-stick are disclosed for use in performing the tasks. A danger indicating icon is presented along with the primary task, and the operator is forced to respond to danger indications thereof by operating a switch which is provided for that purpose.

Apparatus and method for testing human performance

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 of images randomly and non-repetitively to a screen for recognition and response by the individual being tested. The responses are recorded in a compiler means and then compared to the previous results of the same individual which are stored in a data base and then tabulated to provide an output signal indicative of the individual's present ability to perform the task in question.
