The Useful Field of View (UFOV) measures the extent of the visual field from which information is extracted in a single glance. The UFOV is influenced by dividing attention, especially in older subjects (e.g., Sekuler et al., 2000), and the effects of attention predict performance in complex tasks like driving (e.g., Myers et al., 2000). Practice in a UFOV task reduces the effects of divided attention in younger and older subjects (Richards et al., 2006), and also has been shown to improve driving performance in older adults (e.g., Roenker et al., 2003). To the best of our knowledge though, no one has examined if UFOV training affects driving performance similarly across the life span. Therefore, we tested younger adults on a desktop driving simulator before and after nine UFOV training sessions. The UFOV task comprised a central identification task and a peripheral localization task performed under focused- and divided-attention conditions. The driving simulator task consisted of short routes in which we measured overall performance as well as reaction time to central detection and peripheral localization tasks. Results from five younger subjects show that, in the UFOV task, performance on the peripheral task under divided attention conditions improved linearly until it was statistically similar to peripheral task performance under focused attention conditions. This result is similar to that found in Richards et al. (2006). In the driving simulator task, however, we did not find an effect of UFOV practice on either the central or peripheral task. We are currently testing older adults to see if UFOV training offers differing benefits across the lifespan, and examining the effect of driving task difficulty on transfer of learning.
