Research evidence indicates that the environment is an important factor in improving children's development. However, little research has been done in the rural children population regarding the effect of motor affordances on cognitive abilities. Therefore, this study aimed to investigate the relationship between the developmental environment affordances of rural children and their executive functions enhancement.

The present research was an ex-post facto correlational study, which was conducted as field research with applied research purposes. The statistical population of this study was 8 to 10-year-old primary school children (Mean age = 9.10) of East Azerbaijan province from which 93 children were selected through random cluster sampling method as the study samples to participate in the study. To measure the motor development affordances in the home environment, the AGMDQ-1, and to measure the executive functions,  BRIEF test were used.

Based on the results of the multiple linear regression test, a positive significant relationship was observed between motor affordances and inhibition (P=0.042) and between motor affordances and initiation (P=0.008) in 8 to 10-year-old children. Also based on the results, no significant relationship was observed between motor development affordances including stimulants, home environment and active toys, and other components of executive functions (P>0.05).

Based on the results of the present research, children's living environment is an important factor in predicting the components of their executive functions. Accordingly, it is suggested that to improve executive functions during childhood, children should be in richer environments (in terms of the presence of affordances such as active toys).

The aim of this study was to determine the relationship between perceived motivational climate and motivation in adolescent female students. This research was conducted through descriptive and correlational method. The statistical population of this study was all high school female students in East Azerbaijan province, 221 people were selected using cluster sampling method. In order to collect data, exercise behavior adjustment questionnaire and perceived motivational space were used in sport. The results showed that there was a significant relationship between motivational climate and lack of motivation. Also, there was a significant relationship between ego-oriented climate and external motivation and introjected regulation, as well as between the task-oriented climate and internal motivation and the identified regulation. In other words, in the Ego and task perceived motivational climate, both in the model used predict 6% of the changes in the external motivation, 2% of the changes in the introjected regulation, 14% of the identified regulation changes, 12% of internal motivation and 11% of the lack of motivation correctly. Therefore, it can be said that the perceived motivational climate is an important factor and predictor of the type of motivation to exercise in adolescent female students.

The aim of this study was to investigate the relationship between, The levels of motivation and Intention to Continue Physical Activities in female adolescent students. 221 female adolescent students of East Aderbayjan province aged 18-12 years in 2019-2019 were selected by multistage cluster sampling and completed exercise continuity and exercise behavior regulation questionnaires. The collected data were analyzed by SPSS24 software. The findings showed that among the factors of motivation levels, lack of motivation negatively and internal motivation as well as positively identified regulation, they have the ability to predict the Intention to Continue Physical Activities. However, other levels of continuity of motivation, including external motivation and introjected regulation, do not have the ability to predict the desire to continue exercising. Accordingly, it can be said that in creating a desire to continue exercising in adolescent girls, the type of motivation they have created during exercise classes can be a predicting factor.

  Numerous studies have examined self-concept and competitive trait anxiety. But research that examines the link between self-esteem and competitive anxiety has been overlooked.

The purpose of this study was to investigate the relationship between self-concept and trait competitive anxiety in students of Tehran-Campus Nassibeh Cultural University.

This was a descriptive correlational study. The statistical population of this study consisted of 223 undergraduate (19-23 years) undergraduate students in the year 2018. 100 students were randomly selected from the students participating in the indoor competition. The research tools were: SCAT Martens et al. (1990) three-point Competitive Anxiety Inventory (SCAT) and the SCQ Raj Kamarsarasoot Five-Value Self-Concept Questionnaire (1957) with 48 questions. Data were analyzed using Pearson test.

According to the findings of the study, the correlation coefficient between trait competitive anxiety and self-concept indices was 0/016 (α≤ 0/05), meaning that the type of feedback to one's self without any personal judgment or comparison with others with anxiety during the race showed a significant relationship. Gave.

People with high anxiety had lower self-esteem and experienced poorer sport performance.

The aim of this study was to investigate the relationship between, reasons of tendency toward exercise and Intention to Continue Physical Activities in female adolescent students. 221 female adolescent students of East Aderbayjan province aged 18-12 years in 2018-2019 were selected by multistage cluster sampling and completed exercise continuity and Measuring tendency toward exercise questionnaires. The collected data were analyzed by SPSS24 software. The findings showed that There is a positive and significant relationship between the environment and those around, as well as filling leisure time as reasons for the tendency to exercise and intention to continue physical activities. Or the Fatahs also showed that there is no significant relationship between gaining health as well as culture and media with the intention to continue physical activities. Based on this and in general, it can be said that the reason for a person's tendency to exercise and the purpose and motivation of people to participate in physical activities, can be a predictor of the desire to continue exercising.
