Abstract

The goal of this research was to investigate the effects of foveal load on sensitivity in the peripheral visual field. Foveal load was manipulated by comparing the simple fixation of a cross vs. a first-order (i.e., rate) compensatory tracking task. Peripheral sensitivity was determined simultaneously for light flashes presented at different eccentricities along the horizontal meridian. The effects of training on the task were also evaluated in terms of changes in peripheral sensitivity. In general, the results showed no losses in peripheral sensitivity or a "tunnel vision" effect under the experimental conditions employed. These results are contrary to data obtained by previous investigators. Reasons for these findings are discussed.
