Abstract
When participants search the same letter display repeatedly for different targets we might expect
performance to improve on each subsequent search as they memorize characteristics of the display.
However, here we find that search performance improved from a first search to a second search but
not for a third search of the same display. This is predicted by a simple model that supports search
with only a limited capacity short-term memory for items in the display. To support this model we
show that a short-term memory recency effect is present in both the second and the third search.
The magnitude of these effects is the same in both searches and as a result there is no additional
benefit from the second to the third search.
