The center of pressure (COP) tests were performed on the participants in the following four conditions: baseline, control, the external focus of attention (EFA), and the internal focus of attention (IFA). Balance assessment and training were conducted using the Biodex Stability System (BSS).<br> <strong>Results. </strong>Analysis of variance with repeated measures showed that attentional focus affected both the postural and the supra-postural task (p<0.05). Also, the results of independent t-test showed that no significant difference existed between internal-external focus conditions (p<0.05).<br> <strong>Conclusion. </strong>This study suggests that application of automatic control processes can be facilitated by simply directing performers&rsquo; attention away from their own movements.</span></span></div> Focus of Attention, Posture, Supra-Postural Task, Automatic Control 31 37 http://aassjournal.com/browse.php?a_code=A-11-727-1&slc_lang=en&sid=1 Tayebeh Baniasadi baniasadi.tayebe@gmail.com 10031947532846007136 10031947532846007136 Yes Tehran University, Kish International Campus, Kish Island, Iran Mehdi Namazizadeh drmnamazi@yahoo.com 10031947532846007137 10031947532846007137 No Faculty of Physical Education and Sport Science, Khorasgan Branch, Islamic Azad University, Isfahan, Iran Mahmoud Sheikh msheikh@ut.ac.ir 10031947532846007138 10031947532846007138 No Department of Motor Behavior, Faculty of Sport Sciences, University of Tehran, Tehran, Iran
