Across a range of psychometric tests, reaction times slow as adult age increases. These changes have been widely taken to show that cognitive-processing capacities decline across the lifespan. Contrary to this, we suggest that slower responses are not a sign of processing deficits, but instead reflect a growing search problem, which escalates as learning increases the amount of information in memory. A series of computational simulations show how age-related slowing emerges naturally infatcat:satzkmmdqnby3ko5letbevomvm
