The role of familiarity in item recognition, associative recognition, and plurality recognition on self-paced and...

Four experiments compare the effect of familiarity on item, associative, and plurality recognition on self-paced and speeded tests. The familiarity of test items was enhanced by presenting a prime that matched the subsequent test item. On item and plurality recognition tests, participants were more likely to respond "old" to primed than to unprimed test items. In associative recognition, priming increased the proportion of old responses on a speeded test, but not on a self-paced test. This suggests that familiarity plays a larger role in item and plurality recognition than in associative recognition on self-paced tests. On speeded tests, priming has a similar effect on item, associative, and plurality recognition. Results suggest that item and associative recognition rely differentially on familiarity and recollection. They are also consistent with recent evidence suggesting that different processes underlie plurality and associative recognition.
