SUBSIDIARY-TASK ASSESSMENT OF AGE DIFFERENCES IN ATTENTIONAL CAPACITY DURING REAL AND SIMULATED DRIVING: A PER=LIMINARY ANALYSIS OF THE DATA

Advances in ITS in-vehicle technologies promise to impose new information processing demands upon drivers. Potential information "overload" problems may become especially acute among older drivers - the fastest growing segment of the driving population. In this investigation, the efficacy of a subsidiary task technique for detecting and quantifying age differences in the attentional demands of driving related tasks was evaluated. Young and old licensed drivers participated in a simulated as well as an on-the-road driving task while simultaneously performing a series of simple mental arithmetic computations. Response latencies on the mental arithmetic task slowed significantly for the old drivers as the primary task of driving was made more difficult. Steering error did not change under dual task versus single task conditions.
