Thesis:

he Effectiveness of Working Memory Training on Self-Control and Test Anxiety in Female High School Students in Sabzevar City

The aim of the present study was to investigate the effectiveness of working memory training on self-control and test anxiety in female first-year high school students in Sabzevar in the academic year 2025. The sample consisted of 30 students who were randomly divided into two experimental and control groups. The research tools included self-control and test anxiety questionnaires. Data analysis was performed using descriptive tests, data normality tests (Shapiro), homogeneity of variances test (Levin), and analysis of covariance. The results showed that after working memory training, the control domain increased by 80% in the experimental group, while this increase was only 26% in the control group. Also, test anxiety in the experimental group decreased by 35%, which was much greater than the 19% decrease in the control group. Pre-tests of analysis of covariance showed that the data were normal and homogeneity of variances was established. Covariance analysis showed that working memory training had a significant effect on increasing self-control (F=111, p<0.001, ?²=0.81) and reducing test anxiety (F=37.9, p<0.001, ?²=0.594). These results indicate that 81% of the changes in self-control and 59% of the changes in test anxiety of students can be explained by working memory training. Therefore, working memory training is suggested as an effective intervention in improving self-control and reducing test anxiety of female junior high school students.
