Cognitieve training bij oudere bestuurders

Abstract

Since cognitive ability is important for driving, this study investigated whether strengthening cognition, more specific working memory, influences cognitive and driving ability in a positive way. The present study focused on older drivers since with age there is a decrease in cognitive ability. Twenty drivers (aged 65+) were allocated to a control or an experimental group and performed a working memory training at home for 25 consecutive days. Before and after the training, participants were measured on working memory, response inhibition and visual attention in a cognitive test battery. Afterwards, their driving ability was measured in a driving simulator. Results showed that training improved working memory, inhibition and visual attention for all participants. Further, the training improved driving ability of all participants in the experimental group, showing a decreased gap acceptance during post-test. However, these results can be influenced by learning-effect. Especially for crashes, the experimental group showed better results in the post-test than the control group, indicated by a larger decrease of crashes. These results and their implications will be discussed. Keywords: Working Memory, Driving Simulator, Older Drivers, Driving ability, Cognitive ability Words: 7951 Tables: 4 Figures: 6
