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.

The aim of this study was examining the effect of knowledge of results presentation (after successful and unsuccessful trials), on learning and error detection capability in force-produce task. Sixty under graduated students (range age 21.6±4), participated in this study and in order to KR presentation, divided in three groups. One of the groups received KR after successful trials, the other groups after unsuccessful trials. The control groups did not receive any KR. All the participants throughout the trials in the acquisition and retention phases were error estimated. The task was to produce the 70℅ of maximum force of their right hands, by gripping a dynamometer. After data collection, the analysis conducted by using ANOVA repeated measurements for acquisition period, and one way ANOVA for retention test. In acquisition, results showed no significant differences between the first and second groups, on performance and error detection capability of force-produce task (P> 0.05). However in retention (no KR), there was significant differences between two groups (P&le0.05), means that the first group which received KR after successful trials was better than the second group as well as control. This pattern of results suggests that if people receive the KR after successful trials than unsuccessful, the better learning and error detection capability will occur.

The aim of this experiment was to study the effect of computer game on acquisition and retention of free throw basketball skills (accuracy and pattern) and compare this method with two patterning methods (skilled and learning). 50 high school students age range 15-17 years were selected as a research samples. Subjects after participating in the pretest were divided into 5 equal groups and each group practice separately for 2 weeks and 3 sessions per week (total of 6 sessions) their tasks. Acquisition test hold after the last training session and retention test was performed after 24 hours. Data analyzed using variance with repeated measurement. The significance level for all statistical methods was considered p<0/05 and used SPSS 17 for statistical calculations. The results showed that each group at post-test scores on both the accuracy and pattern of pre-test and the most advanced computer game plus exercise group significantly improved. According to the results, this study can state that the the simulation computer game improves learning of motor skills. This method is more effective than learning a skilled and patterning method.

The purpose of this study was to determine the effect of two different age groups (children and young adult) to learning of temporal-special coordination hand movement pattern. Sixty subjects according to the age (children – young adult) and receiving feedback (100%, omitted, self-control) were randomly divided into six groups. This study was done in three days. All subjects practice 100 trails of movement task in each day of first and second days. Retention tests were done in second and third days and reacquisition test was done in the third day. Analysis of variance (ANOVA) with repeated measures and two way ANOVA was used to data analysis. All participants in the first day improved their accuracy across practice trials. In the second day children did not improve their accuracy but young adult experienced improvement across practice trials. There was not significant difference between retention children tests but that was significant about young adult. During the retention tests children who received 100% feedback was significantly better than other children feedback groups and there was no significant between young adult feedback groups. During the reacquisition test children who received 100% feedback was significantly better than other children feedback groups and there was no significant between young adult feedback groups. Results from this study showed young adult are better than children in the learning of this pattern, receiving more feedback can improve motor learning in          children (in contrast with guidance hypothesis) and we must not expect motor skill acquisition occur in children like young adult.

The purpose of this study was to determine the relationship between organizational learning capability and organizational performance in sport and youth offices of Iran's Northern provinces. Statistical population included of all managers, deputies and experts of the sport and youth offices in Iran's Northern provinces (Guilan, Mazandaran and Golestan) and managers and deputies from five selected cities in the year 1391 (N=108). Due to the limited population, the statistical sample was considered as a whole (n=108). For this purpose, organizational learning capability (Gomez, 2005) and organizational performance (Brown, 2001) questionnaires were used. Data analysis was performed at a significant level (p&le0.05) using descriptive statistics (mean and standard deviation, frequency distribution tables) and inferential statistics (Kolmogorov-Smirnov, Pearson correlation coefficient, multiple regression, and conformity factor analysis). Research results indicated that the systematic perspective subscale acquired the highest average in comparison with other organizational learning capabilities (&mu=3.35). Also, there was a significant correlation between organizational learning and organizational performance (p&le0.05, r=0.621). With regard to the linear relationship among variables and the assumption of errors independence from each other, predictor variables (organizational learning capabilities) revealed 37% changes in the rate of organizational performance. Also, while confirming the model parameters, it can be said that the presented model is appropriate and experimental data are coincided enough well with this model. Totally, according to the findings of this research, it is recommended that the different levels of managers make enough efforts to perceive the importance of organizational learning and how to establish these capabilities among the staff.

Ackerman (1988) states intelligence and motor ability as the two important
abilities in three learning stages (cognitive, motor and autonomic) of Fitts and
Posner. Therefore, the present study aims at investigating the relationship
between Intelligence Quotient (IQ), motor fitness and anthropometric
characteristics with basic basketball skills learning stages. The population
includes all seven-to-eleven-year-old boys of Aleshtar city, 1054, 60 of whom
were selected using random cluster sampling method. Data collection tools
included Rion’s IQ inventory, standard tests of motor fitness, and basketball skill
tests of Ifred. Statistical analysis was conducted using Pearson correlation
coefficient and linear regression. Correlation between IQ and performance basic
skills of basketball in cognitive stage of learning was significant and its peak. This
correlation in motor and autonomic stages was also significant but decreased. On
the other hand, the correlation of motor fitness and anthropometric characteristics
with performance basic skills of basketball was low but still significant in cognitive
and motor stages. This correlation reached its peak in autonomic stage. Motor
fitness and anthropometric characteristics are more important in autonomic stage
and IQ is more important in motor fitness in cognitive stages of learning shooting,
passing and dribbling skills in basketball.

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 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.
