Sex, Eye Preference and Speed of Stimulus Effect on Anticipation of Coincidence

Abstract

The intent of this study was examination of effects of sex of subject, eye preference, and speed of stimulus on anticipation of coincidence. 15 men and 15 women made estimates of a baseball's arrival at the front edge of a home plate. Subjects had blocks of trials while standing with either the preferred or nonpreferred eye closest to the oncoming ball, followed by trials of the other eye closest. Balls were projected 45 ft. by a pitching machine at speeds of 35, 40, 45, and 50 mph. Analysis indicated no significant difference for sex or eye preference but a significant speed effect, with the slowest speed being less accurate.
