The present study examined the effects of working memory computer assisted program on improving executive functions of deaf students. Eighteen male deaf students were selected and randomly assigned to either experimental or control groups. Students were administered Stroop Test (Stroop, 1935), Continuous Performance test (Rosvold, Mirsky, Sarason, Bransom, & Beck, 1965), the computerized version of Tower of London Test (Morris, Ahmed, Sted, & Toone, 1993), and the Working Memory Test (Comoldi & Vecchia, 1995). The experimental group received 20 training sessions (45 minutes a session) of working memory computer assisted program (Bokharayian, 2010). The results of t tests indicated experimental group performed better than the control group. Furthermore, one month follow-up indicated no change in executive function scores of deaf students. The findings suggested the effect of working memory computer assisted program on improving of executive functions of deaf students.
