Objective: The current research aimed to investigate the effectiveness of Sternberg's successful intelligence program on working memory and executive functions of sharp-witted primary school students. The statistical population of the current research consisted of all sharp-witted male students of the city of Isfahan in the academic year of 2015-2016. Method: For this purpose, totally 30 sharp-witted male students were selected through multi- stage cluster random sampling method and were randomly assigned to two experimental and control groups (15 students in the experimental group and another 15 students in the control group). The Sternberg's successful intelligence program was administered on the experimental group. The tools used for this research included software to measure working memory and questionnaire (inventory) on rating executive functions of the primary school students. To analyze the research data, multivariate covariance analysis (MANCOVA) was employed. Results: Findings revealed that training of the Sternberg's successful intelligence program was effective on executive functions and emotional-behavioral organization of sharp-witted children but had no impact on the problem-solving-planning capabilities of them. Conclusion: The Sternberg's successful intelligence program could be employed as an intervention method for improving executive functions and working memory of children.
