Background: This study addresses the challenge of enhancing selective attention in skilled badminton players, a critical cognitive skill for optimal performance, by investigating the combined effects of transcranial direct current stimulation (tDCS) and mindfulness training.Aim: The present study was conducted to investigated the effects of a tDCS-mindfulness program on selective attention in skilled badminton players.Materials and Methods: Thirty-six male badminton players (mean age= 23.78±3.09 years) were selected based on exclude and include criteria and randomly divided into three groups of 12, A-tDCS-Mindfulness, sham-tDCS-Mindfulness (five sessions), and control. The Edinburgh Hand Test was used to determine the dominant hemisphere of the brain. The Computerized Stroop Test was used to measure selective attention capacity. Nonparametric Wilcoxon, Kruskal-Wallis and Mann-Whitney U tests were used.Results: The results showed that the within-group changes in both A-tDCS and sham-tDCS mindfulness groups, it was able to have a significant improvement on the Stroop test score and time of interference. In the comparison between groups effect, it was also found that there is a significant difference in time and score between the three groups, and respectively, the A-tDCS mindfulness, sham-tDCS mindfulness and the control group had the best performance. Based on the results of the present research, it was found that the presentation of A-tDCS mindfulness can be more effective on the time and score of selective attention of badminton players.Conclusion: Results suggest that the use of tDCS along with mindfulness can improve selective attention in badminton players.

Background: Researchers have always been interested in the focus of attention and the quiet eye. However, the effect of distance of attentional strategy in different anxiety conditions has remained unclear.Aim: The purpose of this study was to determine the effect of attentional strategies on gaze behavior and the performance of dart throwing in novices under anxiety conditions.Materials and Methods: The participants were 42 female, Alzahra University students, aged 18-35 years. Participants with high trait anxiety (score higher than 24) were excluded using the Sports Competition Anxiety Test through a state anxiety questionnaire. Participants were randomly divided into two groups of high and low-trait anxiety. They performed the dart-throwing task counterbalanced in four different attention strategies (distal external attention, proximal external attention, internal attention, and control). The participants in the high-anxiety group were told that if they performed each throw correctly, they would receive a cash prize, and the low-anxiety group performed the throwing without anxiety and any instruction. At the same time as dart throwing, gaze behavior data was recorded with an eye tracker device. After the anxiety manipulation, the individual's anxiety was measured with Competitive State Anxiety Inventory-2.Results: The results showed that the low-anxiety group performed better than the high-anxiety group (P=0.01). Also, external attention had a lower radial error in both high and low-anxiety groups. No significant difference was found in the average duration and number of fixations between different attentional strategies and groups. The comparison of the mean showed that in the low anxiety group, the fixation duration in the external attention strategy was longer, and in the high anxiety group, the fixation duration in the external attention and control strategies was longer than other strategies.Conclusion: The present study supported the preplanning hypothesis, attentional control theory, and inhibition hypothesis, but was inconsistent with the restricted action hypothesis. These results showed the importance of the effect of anxiety on gaze behavior and performance in directing future research.

Schadenfreude has been defined as the enjoyment of others’ misery; a kind of happiness from malice, which one acquires when one learns that others are lucky or experiencing a setback. The purpose of this study was to analyze the experiences of Sulaymaniyah football team fans regarding the theory of happiness from the Erbil team's discomfort in Iraq. An interview was conducted with the fans who had lived experiences (N = 18) and the data were analyzed using thematic analysis. The findings showed that several factors affect schadenfreude, such as political and governmental problems, managerial weaknesses of responsible people, past problems, and discrimination between teams. The findings extend the theory of social identity theory. According to the results, the managers of the teams and the officials of the Kurdistan Region in Iraq can provide the ground for reducing the happiness of the opponent's team with proper management and non-partisanship of the teams. Research in the field of schadenfreude can reduce the problems of advocacy and the wrong decisions of managers and officials and contribute to equality in this field.

Background: Colors can play an effective role in the level of attention, arousal, anxiety, and motivation of learners in learning. Aim: The purpose of this study was to investigate the effect of the color of educational tools and teaching aids and the role of trait anxiety on learning futsal inside kick skills. Materials and Methods: Sixty football school participants aged 10-12 years, who, had no experience in futsal matches, according to the type of color (warm and cool) and the level of anxiety (high and low) in four groups were selected. The participants performed 135 trials during three acquisition sessions including 3 blocks of 15 and they rested for 5 sec between each attempt and 2 min between each block. At the end of the last session, the acquisition test and after 48 hours, the retention test, and after 15 min, the transfer test were performed in the same session in the presence of the spectators. To analysis the data, from variance analysis tests with repeated measurements were used. For the effectiveness of color in the acquisition phase, the two-way variance analysis test was used to compare the groups at the significant level of P<0.05. Results: The effect of training sessions(P<0.001) and the interactive effect of color and anxiety (P<0.028) and test stages (P<0.001) are significant and the changes in the progress of the groups did not take place in the same way. In subjects with high anxiety, the cool color group had better progress than the warm color group, and in low anxiety subjects, the warm color group had better progress than the cool color group. Therefore, in learning futsal side kick skill in subjects with high and low trait anxiety, the color of the tool is known as an effective factor. Conclusion: The use of a variety of training programs along with the color of the tool can improve the learning of futsal inside kick in teenagers with high and low trait anxiety.
