While there is no such thing as multi-tasking (numerous studies indicate the brain can do only one thing at a time) a person can walk and chew gum at the same time. Those actions, as well as other “muscle memory” functions like typing are the products of habit learning and are controlled by a different part of the brain. Talking on the phone, reading email, listening to the news take place in the declarative memory learning area.
That said, a person can cook and listen to the radio at the same time, the same way a person can eat and watch television at the same time. Different parts of the brain are in use.
Maybe preparing dinner and listening to her family at the same time is a mommy skill.
In case you needed to know this. Because you missed a joke or the weather while stirring your eggs.
