| Summary: | This experiment studied the effects of different levels of foveal cognitive load on the dimensions of the visual lobe. The dimensions of hard shell visual lobes were determined at the 50% detection threshold. The number of correct targets detected seemed unaffected by the foveal load in the near periphery but a decrement occurred beyond 7.7/spl deg/, which indicates that there is no influence on the 50% hard-shell lobe value. But the tunnel vision found beyond this eccentricity decreases the detection probability of the soft-shell lobe. The target detection percentages obtained at no foveal load condition may give overestimates of detection probability for search condition with high foveal cognitive load. |
