Introduction: Although vision is the dominant sensory system in sports, many situations require multisensory integration. It is noteworthy that the effect of auditory stimuli with visual stimuli in athletes has not been comprehensively investigated. Therefore, the present study aimed to investigate the effect of unisensory and multisensory information processing on decision-making under pressure.Methods: The study was conducted as a quasi-experimental design with a statistical population of elite male badminton players. Thirteen of them were selected by simple random sampling. The players were required to respond correctly in a badminton spatial decision-making task under four conditions (visual stimulus, auditory stimulus, congruent visual-auditory stimulus, and incongruent visual-auditory stimulus) in two normal and under-pressure conditions. PsychoPy software was used to design the task and assess decision-making accuracy, and for statistical analysis, repeated measures variance (2×4) was used at a significance level of 0.05.Results: The results indicated that the decision-making accuracy of elite badminton players in the congruent visual-auditory condition (multisensory) was significantly better than the unisensory visual and auditory conditions separately, especially under pressure. Additionally, decision-making accuracy in the incongruent visual-auditory condition was significantly lower than in the other three conditions.Conclusion: It can be concluded that multisensory integration (visual-auditory) enhances decision-making accuracy in elite badminton players more than unisensory processing (either visual or auditory), which can be explained based on information processing theory. The results also showed that decision-making in all four sensory conditions under pressure was better than in normal conditions, which can be attributed to the high level of experience and skill of athletes in pressure conditions.

Introduction: 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.Methods: 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.Results: 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).Conclusion: 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).

It is the basis of every human being's progress in learning, which is in fact one of the most difficult concepts to define. In a successful educational system, students' learning style is always considered as one of the factors affecting academic achievement. Knowledge of students' learning style helps teachers to make optimal use of various learning styles and adopt appropriate teaching methods.The present study was conducted to investigate the relationship between learning styles and cognitive styles among male and female students with the moderating effect of academic levels and gender. For this purpose, 350 undergraduate and graduate students were selected by cluster random sampling method and completed questionnaires of Kolbe's learning styles (1985) and Whitkin's cognitive styles (1971). Data were analyzed using Pearson correlation, independent t-test and multivariate analysis of variance. Results showed that there is no significant correlation between cognitive styles and variables related to learning styles. Also, there was no significant correlation between age and cognitive styles and variables of learning styles, except in active experiments. However, there was a significant correlation between learning styles. The results of group differences showed that undergraduate students tend to be more dependent on the cognitive style than those of masters and boys. There was no statistically significant difference between educational levels and gender in learning styles. Undergraduate students are more inclined toward contextual cognitive styles than graduate students and boys than girls, and style and gender seem to interact with preferences.

The present study aimed to examine the effect of contextual interference on acquisition, retention and transfer of coincidence anticipation task with constant, increasing and decreasing speeds. 36 male physical education participants from Shahid Beheshti University were voluntarily selected and randomly divided into three groups (12 subjects each group) and performed coincidence timing tasks with Bassin anticipation timing. In this research, three separate experiments were used. Experiments consisted of constant speed, increasing speed and decreasing speed. Subjects participated in pretest, acquisition, blocked retention, random retention and transfer tests. Absolute temporal errors were analyzed by one-way ANOVA, ANOVA with repeated measures and Bonferroni post hoc tests (P
