cognitive fatigue

Mathematical disorders, which are rooted in genetic factors and central nervous system dysfunction, can cause cognitive and psychological processing disorders. This study aims to determine the effectiveness of problem-solving training on executive functions and mental fatigue in female students. This study is a quasi-experimental design with a pre-test and post-test with a control group. The statistical population includes female students in the first year of high school in Miandoab city in the academic year 1401-02, from which 40 people were selected as a sample based on the available method and randomly assigned to two control and experimental groups. The research tool includes Coolidge's executive functions, 2002 version, differential or diagnostic tasks (Sedak and Kafta), and a problem-solving training protocol. SPSS 25 software was used to analyze the data. Results were shown that problem-solving training significantly affects executive functions (F=16.35, P< 0.00) and reduces cognitive fatigue (F= F=21.75, P< 0.00) in students. Therefore, problem-solving training as a strong capacity can reduce fatigue and increase executive functions.
