Multitasking takes toll on memory, study finds

A growing body of research shows that juggling many tasks, as so many people do in this technological era, can divide attention and hurt learning and performance. Does it also hinder short-term memory?

That’s the implication of a study being published on Monday in Proceedings of the National Academy of Sciences, a respected journal. The research shows that multitasking takes a significantly greater toll on the working memory of older people.

Researchers said the key finding of the new study is that people between the ages of 60 and 80 have significantly more trouble remembering tasks after experiencing a brief interruption than do people in their 20s and 30s.

During the study, subjects were asked to look at a scene, then were interrupted for several seconds by an image of a person’s face. They were asked to identify the person’s gender and approximate age, and then returned to answer questions about the earlier scene. Older subjects found it much harder to disengage from the interruption and reestablish contact with the scene, the researchers found.
