Do you really know? Can we really multitask effectively?
Oct 20, 2025
Can we really multitask effectively? The discussion uncovers how our brains create the illusion of doing multiple things at once. It highlights that multitasking often isn’t true simultaneous action but rather a rapid switch between tasks. Interestingly, it’s revealed that tasks drawn from different brain functions can be successfully managed together. Finally, the myth of women being better multitaskers is challenged with insights from a study, showing no significant differences in multitasking efficiency across genders.

Episode notes
Multitasking Is Rapid Task Switching
- The brain doesn't truly perform two attention-demanding tasks at once; it rapidly switches between them in milliseconds.
- This switching creates an illusion of multitasking while only one task is processed at any moment.
Prefrontal Load Causes Errors
- The prefrontal cortex coordinates tasks and multitasking places a hefty demand on the brain's energy and effort.
- Adding more than two tasks lengthens reaction time and increases errors until tasks are often abandoned.
Combine Noncompeting Tasks
- Do combine tasks that use different brain systems, like motor skills plus language, to improve multitasking success.
- Avoid pairing tasks that require the same brain functions unless one is automatic from repetition.
