Older Brains and Remembering

A new study has found promising evidence that the older brain's weakened ability to filter out irrelevant information may actually give aging adults a memory advantage over their younger counterparts.

Other research has already shown that aging is associated with a decreased ability to tune out irrelevant information. The current study showed that older brains are less likely to suppress irrelevant information than younger brains and can link the relevant and irrelevant pieces of information together to use this knowledge for subsequent memory tasks.

The older adults showed a 30% advantage over younger adults in their memory. Because this type of knowledge is thought to play a critical role in real world decision-making, older adults may be the wiser decision-makers compared to younger adults because they picked up so much more information. I knew that.
