TIME SHARING BETWEEN COMPENSATORY TRACKING AND SEARCH-AND- RECOGNITION TASKS
THIS STUDY DEALS WITH ONE ASPECT OF DRIVING BEHAVIOR, I.E. , THE SHARING OF TIME BETWEEN TWO TYPES OF ACTIVITIES THAT THE DRIVER IS FORCED TO ACCEPT AS A PART OF THE DRIVING TASK . STEERING AND RECOGNITION BEHAVIOR HAS BEEN ABSTRACTED AND EXPLORED IN THE LABORATORY BY ANALYZING PERFORMANCE ON A COMPENSATORY TRACKING TASK TAKEN AS AN ANALOGUE OF STEERING AND ON A FILMED PRESENTATION OF A SIGN SEARCH-AND- RECOGNITION TASK. THE RELATIVE EFFECTS OF THE INTERACTION BETWEEN TASKS WERE EXPLORED. THE MAIN FINDINGS OF THE STUDY WERE THAT /1/ WHERE TIME SHARING WAS REQUIRED, EACH TYPE OF PERFORMANCE WAS DEGRADED, /2/ INCREASING THE NUMBER OF MESSAGE UNITS APPEARING IN THE RECOGNITION TASK DID NOT DIFFERENTIALLY AFFECT SIMULATED STEERING PERFORMANCE BUT DID INCREASE THE TIME REQUIRED FOR RECOGNITION OF A KEY MESSAGE, /3/ INCREASED SPEED OF THE SIMULATED STEERING TASK DISPLAYED
