Illustration of the visual search task and test-trial stimuli in Experiment 2. Each visual search trial (a) began with a cue that identified the target feature. Then the search array was presented, and participants had to find the target. In the test trials (b), old items were ones that had been presented during visual search, whereas new items were created by taking an old item and changing either a relevant or an irrelevant feature.
