📖 Reading Passage

Recent studies in cognitive psychology have revealed that the human brain's capacity for multitasking is largely illusory. While individuals often believe they can efficiently handle multiple tasks simultaneously, research indicates that what actually occurs is rapid task-switching, which incurs a cognitive cost known as 'switch cost.' This cost manifests as reduced accuracy and increased reaction time when shifting attention between tasks. Furthermore, neuroimaging data show that the prefrontal cortex, responsible for executive control, is heavily taxed during such switching, leading to quicker mental fatigue. These findings challenge the modern workplace's glorification of multitasking, suggesting that sequential focus may enhance overall productivity and reduce errors, particularly in complex problem-solving scenarios.
