Experimental design. (A) Prior to scanning, 64 word pairs were presented sequentially and subjects were instructed to memorize each pair. (B) During scanning, trials randomly alternated between classify and recall task conditions. In the classify task, a green box cued subjects to classify the presented word as living or non-living. In the recall task a red box cued subjects to recall and classify the pair of the presented word. (C) In a post-scan recall test, subjects saw one word at a time from each pair and were asked to recall and vocally report the word’s pair.
