“…And these results can be attributed to the fact that TOH task requires following a set of rules and instructions so that students can perform successfully on it, and it has levels that range in difficulty from the easy to the more difficult level, and we have followed the appropriate gradation with them, and this attracts them to perform effectively on the task, which had the best effect in reducing their impulsiveness. The results of this study are consistent with the results of some other studies, which concluded that the training programs (including those on CT) are effective in reducing impulsivity and improving attentional control (for example, Alqarni & Hammad, 2021;Chambers et al, 2008;Franco et al, 2016;Ghahramaniet al, 2016;Munoz-Olano & Hurtado-Parrado, 2017;Peckham & Johnson, 2018;Rivera-Flores, 2015;Shafiee-Kandjani et al, 2017;Torto-Seidu et al, 2021;Wass et al, 2011Wass et al, , 2012. In contrast, the results of the current study differed with the results of some studies, for example, the study of Karimi Goodarzi et al (2018) concluded that there was no significant difference in hyperactivity/impulsivity between the experimental group (the group to which CT was applied) and control group.…”
