Mean ± SEM scores of explicit recollection and familiarity-based implicit memory in the early and late night retention interval. Respective upper lines indicate mean proportions of actual button press responses of true positive (correctly identified old words with correct list classification), false positives (correctly identified old words with wrong list classification), and “know” classifications (correctly recognized old words but without list membership classification, i.e., true positives button “4”).
