Car driving has been studied by combining it with subsidiary task, performance on which is negatively correlated with perceptual load imposed by changing conditions of traffic; experiment compares subsidiary task which required almost continuous attention to auditory display, and which involved memory spans of only 3 sec, with alternative task which did not require continuous attention, but which involved memory spans of up to 55 sec; this comparison was combined with study of men engaged in 8-hr spells of car driving; some explanations are offered for finding that performance on subsidiary tasks was better at end of workspell than at beginning.
