Older drivers are proportionally at greater risk for accidents than younger drivers. This research examined the methodology for identifying the relationships between ability and skill acquisition with the use of clinical, perceptual, and cognitive batteries. This research also focused on whether ability-skill acquisition relations shift as a result of changes in age or workload level. As part of this research, sixty participants, comprised of three age groups and balanced for gender, were presented computer-generated intersection approaches in a part-task-driving simulator. While moving towards the intersection, the participants were asked to mentally project the progress of crossing traffic and indicate if any of the crossing vehicles would eventually come into conflict with their vehicle. If so, they were then asked to identify which side the conflict came from. Conflict presence and workload level were varied. Dependent measures included results from clinical, perceptual, and cognitive batteries, and accuracy of conflict judgments.

520 $a The amount of variance explained for each battery was affected by age group. Specifically, the results indicate that as people age they require additional cognitive processing, in addition to current levels of perceptual processing, to make conflict judgements. The results also indicated a large number of discrepancies between the types of tests that were significant when examined in isolation and those which contributed significantly to a battery. These discrepancies were of two types. One type of discrepancy was caused by inter-test correlations, the second by potential membership in larger multi-dimensional constructs. Both types of discrepancies provide support for the use of batteries as opposed to individual tests when examining driving performance.
