Abstract :The \\\"Mesulam Cancellation Test\\\" is a test used to measure sustained attention. This study investigates the role of time-of-day effect on cognitive performance by administering the Mesulam Cancellation Test to university students (17 males, 13 females) at three different times of day (8:30 AM, 12:30 PM, and 5 PM). Results indicated that participants exhibited an improved number of correctly marked targets and reduced completion times with repeated testing. Male students made more errors than female students in the final session. These findings are discussed in the context of sustained attention, suggesting that repeated exposure and time-of-day effects significantly influence attention and visuospatial performance.
