The Effectiveness of Executive Functions Program on Performance of Verbal Working Memory in Students with Visual Impairment

Document Type : Research Article



Objective: the aim of this study was to determine the effectiveness of executive functions program on performance of verbal working memory in students with visual impairment. Method: the research was a quasi-experimental study with a pretest-posttest and follow-up with the control group. The statistical population of the study consisted of all students with visual impairment in Tehran 2018-2019. Using an available sampling method, 30 students with the required criteria based on the inclusion criteria were selected and randomly assigned to experimental (n = 15) and control (n = 15) groups. Wechsler intelligence subcomponents were used for data collection. The experimental group was trained in 10 sessions of 45 minutes and the control group did not receive any intervention. ANOVA with repeated measures was used for data analysis.
Results: the results showed that training the executive functions in the experimental group improved performance of verbal working memory and this effect remained to sustain at o month follow-up (p < 0.05).
Conclusion: based on the results of the present study, it can be concluded that executive function training can be used as an intervention method to improve performance of verbal working memory in students with visual impairment.
