Perceptual measures for different target eccentricities for monkeys: summary of the perceptual bias and threshold for saccades to targets 8°, 12°, and 16° in eccentricity for leftward (left) and rightward (right) saccades. The results for both monkeys (monkey Fln, top; monkey Cap, bottom) are displayed (gray, Step condition; black, Blank-step condition). Vertical error bars represent SE.
