However, this dichotomous comparison may oversimplify the variety of attentional focus strategies a learner uses when acquiring a motor skill. Recent research suggests a holistic focus of attention provides a similar benefit over an internal focus in performing a standing long jump, but the generalizability of this effect is unknown. The purpose of this study was to determine how an internal (IF), external (EF), and holistic focus (HF) and control condition impact the learning of a badminton short serve. Novice participants (N = 60) were randomly assigned to IF, EF, HF, or control groups. They practiced the badminton short serve for 150 trials over 5 days and completed retention and transfer tests 48-h post-acquisition. Serve accuracy was analyzed in separate repeated-measures ANOVAs for acquisition and pretest/retention/transfer. All groups improved accuracy through ac...

The semi experimental research conducted with the repeated measures design. 36 high school female students that involved to education in 98-99 were selected via convenient and purposefully manner. Measuring working memory and selective attention was done by using N-back and Stroop tasks and data were analyzed using repeated measure ANOVA by SPSS software at significant level p≤0.05. The results showed that there was significant difference in n-back test after break activities. Pairwise comparisons indicated that the n-back task after eye-open rest was better than other breaks. Furthermore, results showed that there was no significant difference in selective attention. The present findings show that different breaks have a different effect on only working memory performance and not on s...

The present study was carried out by means of semi-experimental research design. Employing the convenience sampling method, 20 students of Chamran University of Ahwaz with average age of 23.45±1.45 were chosen to participate in the study. Each of the participants did a test of strop effect dual task within four intervals of 50, 100, 300, 900 ms between asynchronous onset of the tasks in both congruent and incongruent conditions. The results of repeated measurement test with (p>0.05) significance level, indicate that the response time of the congruent stimulant is quicker compared with the incongruent one. In short intervals, the automatic process of reading the word had no overlap with the process of naming the word. Strop effect in short intervals was not effective and didn’t cause any significant interference. Therefore, the naming process is faster than its reading correspondent...

Twenty-four children (Mage = 9.25 ? 0.53 years) were conveniently selected and randomly assigned into two groups of stereotype threat (with emphasis on individual characteristics, namely, overweight) and control group. The task consisted of maintaining the balance on the stabilometer during 30-second trials. One trial in the pre-test, 10 trials in the acquisition phase and 5 trials in the retention test were run. The findings revealed lower motor learning among the overweight stereotype group compared to the control group. Therefore, it is suggested that in similar situations, coaches can reduce stereotype threat emphasizing on the ineffectiveness of individual characteristics, i.e., overweight on motor performance of children thereby prevent performance and learning disruptions.

Therefore, this preliminary study aimed to investigate the effect of transcranial direct-current stimulation (tDCS) of dorsolateral prefrontal cortex (DLPFC) on performing dual tasks. Twenty-six students (average age 25.2 ± 2.43 years) were selected and then randomly divided into experimental and sham groups. All of the participants conducted the Stroop effect test in a dual task situation before and after the tDCS. This test included two intervals between the stimuli of 100 and 900 ms. The results of mixed-ANOVA showed that the average second reaction time of the experimental stimulated group was reduced (in both dual tasks with congruent and incongruent stimuli) significantly after the tDCS. Therefore, it can be stated that the tDCS of the DLPFC increases the information processing speed and the capacity of attention and, as a result, decreases the effect ...
