Concern over older driver high traffic fatality rates has resulted in an effort to identify risk factors and to develop methods of assessment. This study examines two attention-related tasks, Useful Field of View (UFOV) and Change Blindness (CB), in relation to vision and cognitive test batteries and driving performance measures collected using a simulator and an instrumented vehicle. Eight older adults with Alzheimer’s disease and nine comparison subjects between 64 and 81 participated. Factor analysis results indicate that UFOV and CB relate to different factors. While UFOV relates to memory, decision-making, attention, and visual spatial ability, CB relates to vision and attention. The type of images used on a CB task influence how the task relates to driving performance measures. Researchers should be thoughtful when selecting images to include in CB tasks to maximize insight into real-world driving
