The purpose of this study was to evaluate the effect of motivational covert and overt self-talk on basketball free throw skill learning in adults. 60 students of Gorgan Islamic Azad University based on pretest scores randomly assigned in three equal groups (n₁=n₂=n₃₌20). Participants in motivational covert and overt self-talk conducted basketball shooting skill acquisition in 12 sessions (each session 30 throws) with repeating “I Can” slow and loud respectively before of each throw. The transfer and retention tests were held respectively 24 and 48 hours after the last session of acquisition. Repeated measures and one-way ANOVA were run to analyze the data and LSD post hoc test was used to compare groups. Significance level for all statistical tests was set at p<0.05. Results revealed that the effect of practice sessions (p≤0.05), group (p≤0.05) and practice sessions × group (F_(10.12,57)=5.84,p≤0.05) was significant (p<0.05). Results showed that motivational covert and overt self-talk in acquisition, transfer and retention tests was better than control group. But comparison between covert and overt self-talk was not significant (p>0.05). The results of this study indicate that motivational overt and covert self-talk is useful for learning relatively complex tasks.

The current research aims to compare the effect of basic gymnastic exercises in environments with different colors, on static and dynamic balance. Participants were 40 female students ranging in age from 8 to 10 years, who were classified into three groups: "exercise in the environment with warm colors", "exercise in the environment with cool colors" and "exercise in the environment with compound colors". A pre-test of balance was given to each group in its colored environment. Static and dynamic balance were assessed using the balance subscale of bruininks-oseretsky test of motor proficiency. Then the groups have performed gymnastic exercises in colored environments for 24 sessions, and after 8 weeks, they took the post-test in the same environment. The transfer test was performed in the environment with a neutral color, 48 hours after the post-test. Data were analyzed using one-way ANOVA and ANCOVA tests. The findings showed that the color of the environment had had no effects on the learning and retention of static and dynamic balance.it seems that, the color of learning environment related to type of motor skill.

The purpose of present study was to investigate predictions of challenge point theory (guadagnoli and lee, 2004) through comparing two group of challenging and nonchallenging games in developing manipulative fundamental movement skills. Thirty 4 to 6 years old child were selected from one of the kindergartens of Tehran and were grouped according to pretest scores. The games were used were designed for developing manipulative skills in both groups, however the task difficulty of these games was increased in challenging group while in nonchallenging group it was kept constant. The intervention was 8 weeks, 2 session for each week and 42 minutes for each session. Children's manipulative skills were assessed using Test of Gross Motor Development – second version in the beginning and the end of the intervention. The results of multivariate analysis of variance showed  that improvement groups in total score of manipulative skills and all subscales exept that catching wasn't significant. In total, if the challenge point theories predictions on developing of manipulative skills of healthy children failed to be proved but better improvement of challenging group in catching shows that this method is more effective in developing complex skills.

Observing a model let learners to make a plan of action that can be used for learning motor skills. Moreover, self-talk is a conversation that performers use it either apparently or secretly in order to think about their performance and reinforce it. Therefore, the purpose   of this study was to investigate the effect of observational learning, self-talk and combination of both on boy’s performance. The statistical samples of the present study included 60 students (12.25±1.24) with forth and fifth grade that were selected as available subjects.  After volleyball AAHPERD pre-test, subjects divided into 6 groups: Instructional self-talk (STI), motivational self-talk (STM), observational learning (OB), combination of Instructional self-talk and learning observation (STI-OB), combination of motivational self-talk and observational learning (STM-OB) and control group (CO) and during one day, they were participated in specific intervention that planed for each group. On the first day of intervention, subjects participated in acquisition phase and acquisition test was taken, after 48 hours' retention and transfer test was Held. In each phase of study self-efficacy was examined. The results of two-way ANOVA revealed that there was a significant difference among all training groups with control group (p≤0.05). These results support the use of cognitive factors, self-talk and observational learning and the combination of observational learning and Instructional self-talk as learning facilitator.

Abstract
This study aimed to Comparison of dyad training method with cooperative and competitive approach in the learning of Basketball Free Throw. The study sample included 24 girl’s students aged 13-15 years old who had no experience in free throw. Based on pretest scores, the participants were assigned to either the cooperative dyad training group or the competitive dyad training group. In the competitive dyad training condition, individuals in each dyad had to compete with each other to secure the highest free throw score. At the end of each training session the winner was rewarded. In contrast, in the cooperative dyad training condition, the dyads that attained the score of 75 or more in each training session were rewarded. After the 10th training session, the acquisition of free throw skill was assessed. A week later, the retention and the transfer of free throw skill were assessed. The results indicated that, with regard to the acquisition of free throw skill, in both conditions the participants had made statistically significant progress. In terms of the acquisition and the retention of the target skill, no statistically significant differences were observed between cooperative and competitive training groups. However, with regard to transfer test, the cooperative training group outperformed the competitive training group. Therefore, in comparison to competitive dyad training, cooperative dyad training is more conducive to the acquisition and the retention of free throw skill.

Motor learning or the acquisition of coordination is a process of searching for stable functional coordination patterns, into which a system can settle during a task or activity. Human as complex creatures can choose the best pattern based on conditions within different coordination patterns and also achieve goals of tasks. So the purpose of this study is to determination the effect of a Nonlinear Pedagogy approach for the effectiveness of the movement and acquisition of skills. Accordingly, in this study 14 participants (with the average 19.64 and SD 0.74) are taught the short backhand serve of badminton with using linear and nonlinear pedagogy approaches. Linear approach Based on traditional Viewpoint using the descriptive methods and repetive instructions. On the other hand, nonlinear Pedagogy Approach Based on the ecological dynamics theory using manipulation of task constraints especially task constraints including equipment and rules Planned and conducted. Performance accuracy were selected to analyze further selections and used analysis of covariance to measure the effect of the independent variable measured. The test significance level was considered P <./ 05. Despite the progress of both groups to the pre-test, no difference was observed between the two groups in accuracy scores (F=0.092 and p=0.767) and both were equal to achieve results of the task as an indicator of skill acquisition. Our findings indicate that nonlinear pedagogy approach, resulted from theory of ecological dynamics, consider the complexity of Acquisition the skill and inherent tendency of individuals with providing movement affordances. Also, this approach can be effective in the fulfilment of goal tasks.

The purpose of the present study was to determine the role of errorless and error full training on aiming task learning of normal teens and intellectual disability ones. 20 intellectual disability teenagers were selected from an exceptional school and 20 normal children from the Normal school in Ardebil in the range of 11 to 13 years old (M = 12, SD = 0.8). Normal and intellectual disability individuals were randomly assigned to two errorless and error full training groups according to Wechsler's intelligence test and Alloway's working memory test. The task was to throw basketball balls in the form of a chest pass to the targets with concentric circles. These goals were set at the height of the people's chest in the wall. The subjects performed 200 exercise attempts at the acquisition stage in five training blocks. Single and dual task transfer tests were carried out immediately, 24-hour latency and one week's delay. The data were analyzed using two way repeated measures analysis of variance analysis (ANOVA). The findings showed that the group had the least memory involvement and the least error in both subjects type, in the single task test [P<0.05  and in the dual task test were better [P<0.05 . The normal errorless group was not better than the intellectual disability errorless group, but the normal error full group was better than the intellectual disability error full group. The findings of this study are consistent with the Adam's closed loop theory, the reinvestment theory, and somewhat consistent with the estimates of the challenge point framework regarding the error in the acquisition stage, but these findings are somewhat contradictory with the estimates of the schema theory.

Inclusive education refers to the placement of people with disabilities alongside their peers. Recent studies have found this method to be effective when it comes to manipulating the environment. The study investigated the effects of an inclusive education learning method applied in an extracurricular physical education to promote self-esteem and motor proficiency in a child with developmental Coordination Disorder (DCD). The research is a critical case study that involved one obese boy with DCD (age =8 years, height=127 cm and weight =33 kg) who participated in physical education activities with 14 other children without disability over a period of 9 weeks. Three tools, Cooper Smith self-esteem questionnaire, developmental coordination disorder questionnaire and Bruininks-Oseretsky-2 test and semi-structured interviews were used to collect data. Results of semi-structured interviews showed independence, belief, pleasure, family relationships, educational relationships, and social relationships improved. The Cooper Smith questionnaire also showed general (10 score), family (5 score), social (4 score), and educational self-esteem (6 score) increased. While motor proficiency increased (9 score), the body mass index decreased (1.24 score). Results emphasized the importance of applying nonlinear pedagogy in physical education by manipulating the environment and the task without direct instructions and feedback in inclusive settings.

Using auditory concurrent feedback with the goal of gaze path learning is one of the novelty methods in the attention field. The present study aimed to determine the effect of bisensory feedback using eye movement sonification on the decision-making of the badminton clear shot direction. In a Semi experimental strategy, with pre-post design without a control group and clinical method, participants performed recognizing the direction of the shot under unisensory and bisensory training conditions. Response accuracy, response time, and fixation duration were measured in the pre-test, immediate retention, and delayed retention. The results showed that in the immediate and delayed retention, the bisensory group had higher response accuracy and shorter response time than the unisensory group. The bisensory group had a longer fixation duration in key areas than the unisensory group in both times. The use of auditory feedback can probably be considered as a way to improve decision-making skills at the novice level.

Video feedback is a type of augmented feedback that includes showing an athlete or performing a skill with a video clip of oneself or another person performing a particular skill. The aim of the present study was to determine the effectiveness of dyad training with video feedback on learning crawl swimming. For this purpose, 24 male students ranging in age from 11 to 17 years, who had no previous experience in learning crawl swimming, formed two groups of 12 people in dual practice and dyad training with video feedback. Both groups were first justified by the instructor, then in the double exercise group, one of the trainees entered the water and the other watched him perform out of the water, and after trying, they reviewed the mistakes and movements with their friend. in the dyad rehearsal group, one of the friends filmed another performance and showed it to him. The training intervention lasted for 8 sessions and 10 training attempts in each session. After the end of the eighth session, the 10-meter breast crawl swimming acquisition test was performed, and then a reminder test was performed again one week later and filmed. The results showed that the two groups had significant differences in both acquisition and retention, and the dyad training group with video feedback performed better overall. Based on the results, it can be concluded that the dyad training with video feedback method, in addition to being cost-effective in terms of energy consumption and training space, is also more effective than dyad training in swimming training.
