摘要：AbstractIn this study, were investigated various strategies of instructional and motivational self-talk on components of pass skill and shot performance. 72 students with age range 20/09±1/12 were selected randomly as research samples among the 187 students that were obtained General Physical Education (basketball) in the first semester 88-89 year. Firstly, test the speed and accuracy pass (Two-hand chest pass) and accuracy basketball's shot. Using the K-S test were examined normal distribution of data and then were divided to three groups of 24 persons (control, instructional self-talk [IST] and motivational self-talk [MST]) and were perform a course of training included 12 session (once a week during 20minute). Each group used of appropriate phrases related to instructional and motivational self-talk. Control group wasn’t applied no intervention. The results of paired-t test showed, speed pass and accuracy pass skills performance and accuracy shot had been improve in all groups, but this improvement was significant in speed and accuracy pass. In addition, one-way ANOVA showed IST had better performance than the other groups significantly (P<0/05) in accuracy pass and shot. But MST group performed speed passing faster than control group significantly (P<0/05). Overall, results showed that IST is more effective in skills which required precision and timing and MST is more beneficial in skills based on speed.
