Behavioral protocol. Left: Prior to scanning, subjects studied word pair associates. Low-study pairs were presented once and high-study pairs were presented four times. Right: During event-related fMRI, subjects performed a word recognition task with incidental picture encoding. A previously studied or novel word was presented, immediately followed by a picture. Subjects were instructed to respond “old” or “new” to the word and attend to both the word and picture. [Color figure can be viewed in the online issue, which is available at wileyonlinelibrary.com.]
