Twenty-four subjects learned a list of 40 words. They were then tested on half of the words after 4min and on the other half after seven days. Two types of testing were used: (a) recognition of words that had been encountered in the study phase, and (b) perceptual identification in which subjects were asked to report the words presented for 40ms prior to replacement by the mask. Recognition memory was significantly diminished over the 7-day retention interval, whereas performance in perceptual identification after 4min did not differ from performance after seven days. In addition to that, priming effects were confirmed in both retention intervals. These results suggest that priming effects in perceptual identification are independent of recognition memory and task demands of perceptual identification are similar with those of word-fragment completion in which subjects are asked to complete graphemic word-fragments by inserting the missing letters.
