  • Title: Comparative studies of color fields, visual acuity fields, and movement perception limits among varsity athletes and non-varsity groups.
    Author: Mizusawa K, Sweeting RL, Knouse SB.
    Journal: Percept Mot Skills; 1983 Jun; 56(3):887-92. PubMed ID: 6877976.
    Abstract:
    This paper examined effects of sports practice on patterns of color fields, limits of peripheral movement perception, and visual acuity field by comparing varsity ball players and non-varsity control groups. The first study measured extent of color fields and limits of horizontal and vertical meridians for peripheral movement perception of 139 college students. The second study tested visual acuity fields of female and male basketball players and female and male controls. The first study indicated that athletes had wider limits for horizontal movement perception, while the non-athletes had better vertical movement perception limits. Basketball players demonstrated color fields and limits for peripheral movement perception superior to those of soccer players. In the second study, athletes did not have any wider visual acuity fields than non-athletes, but their movement-perception limits were significantly wider than those of non-athletes.
