Abstract
The purpose of present study was investigation of the effect of attention direction variation by instructional self-talk on performance and learning of Basketball free throw. Therefore, 33 novice female students (mean of the age=22 yr.) who had intermediate trait anxiety were selected randomly. The participants were assigned to 3 matched groups according to pretest. The self-talk with internal and external focus groups repeated the words “wrist” and “center of ring”, respectively, before each free throw during 6 sessions (2 blocks of 10 trials in each session). Control group performed the free throws without self-talk. Retention test was performed 48 hours after the acquisition phase and transfer test was done after that with spectators. In each test, throw accuracy was measured by a 5-point scale. Results of mix 2-factor and one-way ANOVA did not indicate significant differences between acquisition, retention, and transfer groups (p>.05), but the within subjects effect of external focus of attention on transfer was significant (p<.05). Therefore, it seems use of self-talk and its attentional focus variation is not necessary for novice Basketball players.

Abstract
The purpose of this study was the effect of visual illusions and focus of attention instructions on the performance and learning of the golf putt. A total of 48 students with an age range of 7-9 years were selected from the community in a targeted manner and randomly divided into four groups (large visual illusion with external focus of attention instruction, large visual illusion with internal focus of attention instruction, small visual illusion with external focus of attention instruction, small visual illusion internal focus of attention instruction) were allocated.The current research was conducted in five different phases of pre-test, acquisition, retention, transfer and dual task. results a mixed two-way analysis of variance (ANOVA) repeated measure, showed that in all phases, especially the dual task, the two groups of external focus of attention with large and small visual illusion performed better than other groups. These findings showed the importance of external attention and additive Effects of an External Focus and visual illusions in Learning a Motor Skill, which may be platform for encourages implicit learning mechanisms, it is recommended that physical education coaches use psychological variables (external focus of attention and visual illusions) in practicing golf putting skills.

Abstract
ABSTRACT
This study aimed to examine the role of working memory in the effectiveness of errorless protocols for facilitating implicit motor learning in adolescents with and without intellectual disabilities. A total of 20 adolescent boys with intellectual disabilities and 20 typically developing adolescent boys (mean age = 12.12 ± 0.80 years) voluntarily participated in the experiment. The participants with and without intellectual disabilities were separately assigned to either the errorless or errorful practice group based on their IQ scores. The task involved aiming at concentric targets using a mini-basketball. The errorless practice group practiced the task from near to far distances (3, 3.25, 3.5, and 3.75 meters), while the errorful practice group practiced from far to near distances. Implicit motor learning activation was assessed by comparing performances in dual-task conditions immediately after practice, as well as after 24 hours and one week. Additionally, working memory engagement during practice was evaluated. Results indicated that the errorless group, which required less working memory engagement during practice, showed significantly better performance in dual-task conditions compared to the errorful group (p < 0.05). The findings regarding the impact of practice errors on enhancing implicit motor learning in both adolescents with and without intellectual disabilities are crucial for developing motor skill acquisition strategies for adolescents, regardless of cognitive abilities. The results were consistent with the predictions of Adams' closed-loop theory and the reinvestment theory concerning the benefits of reducing errors in motor learning, but they were not aligned with Schmidt's schema theory.
