The Effect of a Central Task on Luminance Thresholds for Peripherally Presented Stimuli

The effect of a central task on peripheral vision was investigated by obtaining luminance thresholds for stimuli presented from 20° to 90° in the periphery. A control group observed a steady foveal fixation light. For the two experimental groups, the fixation light was interrupted periodically and t...
