Abstract
This research aims at studying the effect of different Practice Schedules (Blocked, Random, and systematically increasing) on acquisition, retention and transfer different basketball pass Species (overhead, chest and single arm). Subjects included 45 secondary male students (Mean age 17.14± 0.75) whom were assigned into three matched groups Blocked, Random and systematically increasing (its mention increasing systematically contextual interference to in training duration) following pretest. The subjects didn’t have any experience in playing basketball. At the determined and given condition for each group, subjects performed the task for 9 sessions 9 trials in each session. After 24 hour, retention and transfer tests with 4 trials in each pass were taken. Results showed effect of practice session was significant but no significant difference in acquisition between groups. In retention and transfer tests, there were significant differences between mean scores of practice groups, that supported Magill and Hall theory (1990) and challenge point idea of Guadagnoli and Lee (2004).

Abstract
Perfectionism and mood states are psychological constructs which according to the results of recent studies, have substantial role in sport performance. The purpose of this research was to determine and compare therelationship between sport perfectionism and mood states inteam and idiviual sports athletes. The Research method used is descriptive with a correlative approach. Based on random sampling, 70 athletes in individual fields and 70 in team fields have selected from national super league. for data collection, two questionnaires of sport perfectionism, Dunn,et al (2006) and Brums, Terry et.al (2003) were used and for data analysis took Pearson correlation coefficient, independent t-test and Z Fischer. The results indicated that in team and individual fields, there was a positively significant relationship between concern over mistakes as a negative aspect of perfectionism and scores obtained on negative mood before competition, while such relationship was negative for vigor. There was no significant relationship between perfectionism of athletes of team and individual but depression and fatigueof team athletes significantly was better than individual athletes. Finally the results of Z Fischer test showed no significant difference between perfectionism correlation coefficients and mood states before competition in team and individual athletes. Negative performance via negative reaction mechanism regarding to error and mistake causes negative mood while positive perfectionism due to motivational effects results in improving positive mood.

Abstract
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.

Abstract
This investigation aimed to determine the role of using specific gestures in simple arithmetic. Forty-seven university students (25 females; Mage = 23.45 ± 3.51 years) voluntarily participated in this study. The participants completed two tasks. In the item-counting task, the participants were shown sets of identical colored squares and asked to count a specific color by either finger-pointing, nodding, or without any gestures while counting. After completing the counting task and for measurement of the working memory performance, the participants were asked to recall lists of alphabets that were previously to them. The results revealed that when using finger-pointing or nodding while counting, the participants counted faster and more accurately than when gestures were not allowed. The results of the memory task showed that the participants retrieved significantly more alphabets and more quickly when using finger-pointing or nodding while counting than when not gesturing. Thus, the gestures helped to free up cognitive resources. The findings support the hypothesis that gestures may facilitate cognitive functions by reducing cognitive load. This present investigation, consistent with previous research, suggests that we can benefit from using our hand and head movements to facilitate some simple arithmetic tasks.

Abstract
The purpose of this research was to investigate the environmentally friendly behavior of active sports tourists visiting Bushehr beach sports tourism destinations for beach and water sports. The research sample consisted of 102 active sports tourists who were selected by available method and completed the research questionnaire. The research tools included questionnaires of Eco-friendly compliance, Eco-friendly policy, Eco-friendly disposition and word-of-mouth advertisement by Kontojiani and Kotoris (2014). Frequency and percentage indices were used for descriptive statistics and structural equation modeling was done using PLS3 software in the inferential statistics section. The results showed that the Eco-friendly compliance of sports recreation centers providing coastal sports tourism services has a significant effect on the word-of-mouth promotion of active sports tourists, and also the Eco-friendly policy among sports tourists has a significant effect on the Eco-friendly disposition. Eco-friendly disposition did not have a causal relationship with the word-of-mouth advertising of sports tourists. The compliance of sports tourism service providers with environmental protection indicators did not have a significant effect on the Eco-friendly disposition, and this indicates that those sports tourists who have an Eco-friendly policy, in any situation, they show their Eco-friendly disposition. Considering the influence of the Eco-friendly policy on the Eco-friendly disposition of sports tourists, it is suggested that courses and educational programs in different platforms for members of the society, especially sports tourists, in order to familiarize themselves with environmental issues and improve the way and their environmental attitude should be done.
