This study aims to compare response inhibition and working memory precision between adults with type II diabetes and healthy individuals. Working memory and response inhibition are key executive functions critical for cognitive processes such as decision-making, reasoning, and self-regulation. Type II diabetes, beyond its physical complications, significantly affects cognitive functions including working memory and inhibitory control, which may reduce patients’ quality of life. The research will use two standardized computerized tasks: a Delayed Match to Sample task to assess working memory precision, and a computerized Stroop test to measure response inhibition. The study population will include adults aged 40 to 60 living in Tehran, divided into two groups—patients diagnosed with type II diabetes and healthy controls—selected through purposive sampling. A minimum sample size of 60 participants (30 in each group) is planned. Data will be analyzed using statistical tests such as independent t-tests, analysis of covariance (ANCOVA), and correlation coefficients to evaluate differences and relationships between variables. This quantitative, comparative research aims to fill the gap in existing literature by simultaneously examining these two cognitive functions in diabetic patients. Findings from this study can improve understanding of the cognitive impairments related to type II diabetes and guide the development of targeted cognitive-behavioral interventions. Ultimately, this could help enhance disease self-management and improve overall quality of life for individuals living with type II diabetes.
