Introduction: A key characteristic of human information processing is goal orientation, which allows us to focus on specific aspects of a current stimulus while ignoring others based on our cognitive goals. Previous studies have shown that Reaction Time (RT) can be influenced by interference. This study aims to investigate this effect using the Flanker paradigm and explain how different interference types impact RT and accuracy. Also, this study examined RT for correct and incorrect responses.
Materials and Methods: This study was conducted on 110 female students from schools in Mashhad City, Iran, during the 2022-2023 academic year. Participants performed both the Go/No-Go task (which lacks interference) and the Flanker task (which involves four types of interference). The researcher analyzed the mean RT for both tasks, the impact of interference on RT and accuracy, and the RT for correct and incorrect responses. Results: Findings confirmed that interference in the Flanker task affects RT. It has been found that incongruent interference significantly impacts both accuracy and RT (P< 0.05), and incorrect responses were slower than correct ones, likely due to delays as the brain reassesses and experiences conflict about the correct response.
Conclusion: The study demonstrates that both the presence and type of interference affect reaction time and accuracy, with reaction time being longer for incorrect responses.
