| Popis: | Although previous studies have assessed the allocation of central and peripheral vision in functional field of view (FFOV) tasks, few studies have directly assessed changes in the FFOV within a driving environment. By modifying a typical FFOV task paradigm with central and peripheral target tasks occurring in a low-fidelity driving simulation, a method of assessing the allocation of peripheral vision resources was developed. Two experiments were conducted to: 1) validate the FFOV task in a driving simulation environment, 2) assess peripheral attention distribution due to the simulation background, and 3) assess peripheral attention distribution due to a basic vehicle steering task. In Experiment 1, the central and peripheral task performance of 17 college undergraduates (8 males, 9 females) was compared when provided a blank white screen versus the driving simulation background (i.e., driver's vehicle moving on a winding road towards a distant horizon). In Experiment 2, the central and peripheral task performance of 27 college undergraduates (19 male, 8 female) was assessed when provided the same driving simulation background as in Experiment 1, but with the additional task of controlling the vehicle's lane position. Both experiments used a central, two-choice object recognition task that varied in object display speed (160, 260 ms) with a concurrent peripheral target detection task that varied in eccentricity (10, 20, 30° visual angle) and radial position (4 cardinal, 4 oblique). Results from both experiments indicated a successful replication of a FFOV task with poorer peripheral task performance as peripheral targets increased in display speed and eccentricity. Analysis of peripheral target localization accuracy performance suggested a lower visual field dominance and a differentiated pattern of peripheral attention allocation for the driving environment and when the participants were performing the steering task. |
