Is Multitasking Bad For Your Brain? …How Your Brain Handles Divided Attention
Multitasking may give you the illusion that you’re getting more done. But it’s actually a poor tool for efficiency. Despite that — and after decades of ever-increasing expectations for productivity — many take pride in the attempt to juggle multiple projects In one survey of U.S. adults, 79% said they were either “somewhat good” or […] The post Is Multitasking Bad For Your Brain? …How Your Brain…
Multitasking, a common practice in modern society, may seem like a time-saving strategy, but it can actually hinder efficiency and brain health. Despite the belief that multitasking enables individuals to accomplish more in less time, neuroscientists argue otherwise, stating that it is essentially a constant cycle of mental interruptions.
The term "multitasking" has its origins in computer science, but it has been adopted by humans as well. However, unlike computers, human brains lack the necessary architecture to perform multiple tasks simultaneously. In reality, multitasking is a form of task switching, where the brain alternates between activities by stopping the current task and starting another. This process is less efficient and more taxing on the brain.
Two key areas of the brain are heavily involved in multitasking: the parietal lobe, which manages attention allocation, and the prefrontal cortex, responsible for executive functions like decision-making, impulse control, and working memory. When multitasking, the brain rapidly switches between tasks, leading to diminished overall electrical activity and decreased performance.
Task switching, a form of multitasking, is when the brain alternates between two concentration-requiring tasks. This process can slow down performance and accuracy by up to 40%, also known as the "switch cost." Emotional multitasking, managing multiple emotions simultaneously (e.g., grieving while maintaining a cheerful demeanor at work), is another common form of multitasking. While not extensively researched, it can be exhausting and result in emotional detachment.
Digital multitasking, the use of multiple devices simultaneously, is particularly widespread, with 90% of Americans engaging in this behavior. Studies suggest that heavy media multitaskers may experience problems with memory and executive function. Passive multitasking, the closest your brain can get to genuine multitasking, involves pairing concentration-intensive tasks with automatic physical activities (e.g., folding laundry while talking on the phone). This allows the brain to focus on one task at a time.
Multitasking can negatively impact mental health by exhausting mental energy and leading to decreased decision-making, planning, and prioritization abilities. Research has shown that constantly switching between tasks can make it feel uncomfortable to focus for extended periods. Consequently, people may feel cranky and make more mistakes when attempting to multitask.
