Performance on a virtual environment shopping task and adaptive functioning among older adults.

Neuropsychologists are often asked to evaluate patients' functional capacities, yet traditional neuropsychological tests have limited correspondence with real-world outcomes. The Virtual Environment Grocery Store (VEGS) is a virtual environment that simulates shopping tasks. The purpose of this study was to investigate the relationship between older adults' performance on the VEGS in relation to their self-reported adaptive functioning as well as performance on a performance-based adaptive functioning measure.
