Effects of training on near-far response time as measured by the distance rock test.


The practice effects of specific visual training were demonstrated on twelve seventh grade students and seven optometry students using a distance rock test to measure distance-near response time. Fourteen practice sessions resulted in a 49% improvement for seventh grade students (range 15 to 78%) and a 40% improvement in cycles per minute for college students (range 24 to 64%). Errors were corresponding reduced as cycles per minute were increased.
