Although driving simulators are increasingly used in research because they allow precise investigation of critical issues which would be unsafe or impractical to study in the field, simulator studies can be costly due to high levels of data loss. These losses accrue when participants lack the skill to handle a simulator as if it were a real car or become sick and must discontinue participation. Older participants often suffer significant data losses, and it can be time consuming and expensive to recruit additional participants to replace lost data. During one such study, skill deficits in simulator handling were observed and a guided practice scenario developed to correct the issue. Resulting data were significantly more consistent and suggestive of increased skill. The current research proposes: to extend these findings among older adults to handling the simulator on curving roads and during turns at intersections; to determine whether an automated practice scenario can provide similar benefits; and explore whether the benefits of guided practice extend to reducing incidence of simulator sickness. Preventing data loss from data validity and simulator sickness issues would be of great benefit to researchers working in partnership with the ASAP Center and using simulators.
