17-34 Segment 2: Multitasking: Practically Impossible

 

Do you consider yourself a multitasker? Are you reading this while you watch the news? Although you might think you are good at multitasking, research shows around 97.5% of the population is actually bad at doing two things at once.

University of Utah Professor Dr. David Strayer says that while everyone thinks they are good at multitasking, it actually blinds us to what we’re doing. For example, if you drive while talking on the phone, you might not remember the full conversation because you needed to focus on the road. Multitasking places demands on certain areas of the brain, and most of the time the brain cannot accept two demands at once. Researchers also found those who frequently multitask tend to be more impulsive and sensation-seeking.

Researchers call people who can actually multitask “supertaskers.”  Supertaskers’ brains  allow them to efficiently carry out two activities at once, and they develop this talent at birth.

17-20 Segment 1: Elephant DNA: The secret to cancer suppression?

DNA mutations happen all the time in the body, but the immune system usually detects and deals with them. When the system fails, cancer results. Yet some animals, such as elephants, almost never get cancer, and scientists have learned that the elephant DNA repair system is 20 times more powerful than the human system.

Lupus results when the immune system turns on the body, producing inflammatory attacks on virtually any organ. A minority of patients have lupus only on the skin, and while this is not life threatening, it can still be psychologically devastating.

15-32 Segment 2: Multitasking

 

Synopsis: Multitasking seems like a necessity for most people, and most of us think it inproves our efficiency. However, studies show that only a tiny proportion of people can juggle tasks well. Researchers discuss why our brains can’t do two things at once, and why “supertaskers” may be different.

Host: Nancy Benson. Guests: Dr. David Strayer, Professor of Cognition Neurosciences, University of Utah; Dr. Jayson Watson, Associate Professor of Psychology, University of Utah
