Abstract

A study was designed in order to assess the effectiveness of a positive self-modeling strategy in increasing the performance of four University of the Pacific baseball players. A multiple baseline design across participants was used as a means of assessing the effectiveness of the self-modeling technique. Participants viewed edited positive self-modeling videotapes of their own batting performance. Measures were taken on: (a) the number of line drive hits; (b) ground ball hits; (c) the number of times the participant hit a ground ball, but was thrown out; (d) the number of times the participant hit a line drive, but it was caught; (e) swings and misses; (f) not swinging at a strike (called strikes); (g) not swinging at a ball (called balls); (h) the number of foul balls; and (i) the number of pop ups. In addition, batting averages were kept for game performance. It was expected that participants would show an increase in hits, a decrease in hit outs, a decrease in called strikes, an increase in called balls, a decrease in foul balls, and an increase in batting average when each participant began the positive self-modeling. The performance of those participants not yet viewing their positive self-modeling tape was not expected to show such improvement. Improvement was observed in three out of the four participants.
