Asymmetry of the perceptual span in reading

George W. McConkie, Keith Rayner

Research output: Contribution to journalArticlepeer-review


An on-line computer technique was used to determine whether three skilled readers acquired visual information equally far to the left and right of central vision during fixations in reading. None of the subjects appeared to use visual information more than four character positions to the left of the fixation point (smaller distances were not tested), though all of them acquired visual information substantially further than that to the right. Thus, the region of useful visual information in reading is asymmetric around the fixation point.
