Alternative Reason for Age-Related Cognitive Decline
As adults age, their performance on many psychometric tests changes systematically, a finding that is widely taken to reveal that cognitive information-processing capacities decline across adulthood. Contrary to this, we suggest that older adults'; changing performance reflects memory search demands, which escalate as experience grows. A series of simulations show how the performance patterns observed across adulthood emerge naturally in learning models as they acquire knowledge. The simulati...Folksonomies: information entropy cognition

The idea that as we grow older, our brains have more information to sort through, which makes it take longer to find the data we need.
