| Abstract(in English) | This study examined the existence of a visual field anisotropy for orienting of sustained attention in a dual-task setting. In the experiment, a circular arrangement of stimulus elements (Gabor patches) was successively presented during a 40-min vigil. A primary task was a simple detection task requiring subjects to determine whether all of the elements were same or whether there was an odd element in the upper left, upper right, lower left, or lower right visual fields. A secondary task was a frequency discrimination of tone signals. Results indicated that, for the primary detection task, the perceptual sensitivity (A^') in the left visual filed was higher than in the right visual field but decreased over time on task while A^' in the right visual field remained stable over time. The implications for the functional lateral asymmetry in human sustained attention are discussed. |
