Results for interaction effects with practice of age and cognitive processing speed on traffic avoidance. For age, predictions are shown for an individual at age 51, one SD below the sample mean; at age 58, at the sample mean; and at age 64, at one SD above the sample mean. For processing speed, predictions are for an individual one SD below the mean; at the mean; and one SD above the mean based on the values of a reference sample enrolled early in the study. Older adults and those with slower processing speed do not benefit from practice.
