Why older people remember details less well

You know that from the wardrobe or from that one kitchen drawer that you've been wanting to clear out for months: the storage compartments are stuffed to the brim. As soon as you rummage around in it, all sorts of things fall into your hands - but rarely what you are looking for.

One can probably imagine the processes that take place in the brains of older people when retrieving memories in a very similar way. This is the conclusion of the cognitive scientist Lynn Hasher from the Canadian Baycrest's Rotman Research Institute in an article that has now appeared in the journal "Trends in Cognitive Sciences".

The fact that seniors have problems remembering certain details is not because they remember too little information - but too much.
