The Effectiveness of Computer-Based Cognitive Rehabilitation on Cognitive Flexibility and Selective Attention of High School Students

The current paper aimed to investigate the effectiveness of computer-based cognitive rehabilitation on cognitive flexibility and selective attention of high school students. A total of 30 high school students from Tehran were selected. The participants were randomly divided into two groups: experimental and control, using a convenience sampling method. The sample size for each group was determined to be 15, based on an effect size of 0.3, a power of 0.8, and an alpha of 0.05. The experimental group received 16 sessions of 45-minute computer-based cognitive rehabilitation intervention. The control group received no intervention. Research tools included the Wisconsin Card Sorting Test (WCST) and Stroop Color Word Test (SCWT). The data were analyzed using multivariate analysis of variance (MANOVA) with SPSS 26 software. The results showed that there was a significant difference between the experimental and control groups in some components of cognitive flexibility and selective attention. The findings demonstrated that computer-based cognitive rehabilitation intervention was effective on cognitive flexibility and selective attention of high school students.
