Symptoms of ADHD can be categorized into three subtypes: hyperactivity, inattention, and impulsivity. Males typically exhibit more external symptoms, while females tend to display more internal symptoms, such as inattention. However, both genders are diagnosed using the same criteria, resulting in a higher rate of ADHD diagnosis among males. Our understanding of gender differences in the presentation of symptoms, particularly inattention, remains limited. However, exploring the concept of cognitive flexibility becomes relevant when examining inattention, as it encompasses the ability to adapt and shift one's thinking and behavior in response to changing circumstances or tasks. By considering cognitive flexibility, we can gain valuable insights into how inattention may impact individuals with ADHD and potentially contribute to gender differences in symptomatology. A total of 100 participants completed a computer-based task that assessed task-switching performance which measured reaction time and accuracy for switch cost and incongruent cost. A Multiple Regression Analysis was conducted to examine the relationships between gender, inattention, and task-switching performance. The results of the study did not yield statistically significant findings, indicating no substantial gender differences in task-switching performance and its association with inattention in individuals with ADHD. A few limitations of the study include a relatively small sample size and the possibility that females filled in the self- report questionnaire based on their presumption that they are less likely to have characteristics of ADHD. Future studies should focus on larger and more diverse samples to enhance the generalizability of the findings.Show less
