EFFECTS OF PRACTICE AND ALCOHOL ON SELECTED SKILLS: IMPLICATIONS FOR AN AUTOMOBILE ALCOHOL IGNITION INTERLOCK

DRIVERS PRACTICED TWO PSYCHOMOTOR TASKS BEFORE BEING TESTED DURING ABSORPTION, PEAK AND ELIMINATION PHASES OF THE BLOOD ALCOHOL CYCLE AT BAC'S OF 0.05%, 0.10%, AND 0.05%. A SIGNIFICANT PERFORMANCE DECREMENT WAS FOUND AT THE 0.10% BAC LEVEL COMPARED TO THE PERFORMANCE AT 0% BAC, AFTER IMPROVEMENTS DUE TO PRACTICE HAD CEASED ON BOTH TASKS USED. THE TASK INVOLVING STYLUS TRACKING SHOWED REASONABLE TEST DISCRIMINATION BETWEEN SUBJECTS WHEN SOBER AND AFTER DRINKING. /AUTHOR/
