Life's increasing demands lead people to multitasking, a concept often promoted by gurus and life hackers. The term originated in the '60s in the context of computer performance. However, the human brain, unlike a computer, has limited attention. Visual attention is likened to a spotlight or zoom lens, allowing focus on specific details. Despite receiving vast sensory information, only a small part reaches conscious awareness. Focused attention is powerful, but it can lead to inattention blindness, missing crucial details. Multitasking is challenging as the brain struggles to process everything simultaneously, affecting task performance. Driving and talking on a hands-free phone, seemingly different tasks, share visual resources, making multitasking complex. Research indicates that multitasking makes us inefficient and, at times, perilous. The brain isn't wired for doing multiple tasks simultaneously.
