AN INVESTIGATION OF SERIAL CHOICE REACTION TIME AS THE BASIS FOR AN ALCOHOL INTERLOCK

TWO MEASURES OF DRIVER PERFORMANCE, THE TOTAL TIME TO COMPLETE A SERIAL CHOICE REACTION TIME (SCRT) TASK PLUS THE NUMBER OF ERRORS, AND THE NUMBER OF RESPONSE TIMES EXCEEDING 1.1 SECONDS DURATION PLUS THE NUMBER OF ERRORS (PS), WERE INVESTIGATED. BOTH MEASURES INCREASED IN PROPORTION TO THE SQUARE OF THE BLOOD ALCOHOL LEVEL (BAL) WITH THE PS MEASURE INCREASING MORE RAPIDLY. A SEQUENTIAL CRITERIA TASK THAT MINIMIZES TASK DURATION (LESS THAN SEVEN SECONDS) IS PROPOSED. THIS TASK WOULD REJECT APPROXIMATELY 30% OF THE SUBJECTS AT 0.10% BAL WHILE ONLY FAILING 1% WHEN SOBER. SCRT TASKS SHOW PROMISE AS A BASIS FOR AN IGNITION INTERLOCK, ALTHOUGH ADDITIONAL WORK IS NECESSARY.
