Abstract

Visual stimulation training films were developed by filming collegiate baseball pitchers throwing fastballs and curves with the camera located in the right handed batters box. Films were then edited into a series of learning trials in which subjects were required to respond to questions regarding the type of pitch and its location in the hitting area. Fifty-nine collegiate batters participated in two separate studies to evaluate batters improvement in pitch recognition and location. The dependent variables were subjects 1) recognition scores and 2) location scores on a real time three dimensional measure of their visual skills by means of the Visual Interruption System, an apparatus designed for use in a bullpen. Group comparisons by means of t tests indicated significant gains in location scores and non significant changes in pitch recognition scores (probably due to initially high pretest levels). These gains occurred with use of slow motion or real time films and most of the gains were maintained in a six week follow up posttest. Verf.-Referat
