The present paper addresses the problems of whether recognition failure of recallable words is a function of both recognition and recall, and whether recognition failure is restricted to a small and specifiable subset of study items. A meta-analysis of the Nilsson-Gardiner database showed that recognition given recall was positively correlated with recognition and negatively correlated with recall. Two new experiments are reported, the first one using 48 word pairs for which recognition failure was found in previous studies. An item analysis of the data demonstrated that recognition failure occurred primarily with noun-adjective pairs. The second experiment compared Norwegian-American and American-Norwegian name pairs. Widedeviation from the Tulving-Wiseman function (Tulving & Wiseman, 1975)was observed for the latter condition. In both conditions, recognition failure occurred with only the items for which the beginnings of names shared three or more letters. It is concluded that recognition failure occurs when there exists a relationship between the members of an A-B pair that is independent of their pairing in the study context. The Tulving-Wiseman function is the result of collapsing across items in the analysis of previous studies.Both remembering and forgetting are imperfect phenomena. A list item that is forgotten on one occasion may be remembered on a later occasion. Tulving and his colleagues (Tulving, 1983) have contributed many studies ofsuch fluctuations in retrieval that make use ofa common experimental paradigm, a procedure that has been called the recognition-failure paradigm. In this paradigm, subjects study a list of paired, A-B, items (e.g., cabbageround). After a certain retention interval, they are given a recognition test for the B words (e.g., round) in the absence ofthe A words. This is followed by a cued recall test in which they are given A (e.g., cabbage) and asked to retrieve B. Tulving found that a certain proportion of the B words that were not recognized when used as targets on the recognition test were nevertheless recalled in response to their corresponding A word in the cued recall test. This finding is commonly referred to as recognition failure of recallable words, or just recognition failure. -Accepted by previous editor, Geoffrey R. Loftus Tulving (1983) organized the results of experiments using the recognition-failure paradigm in 2 X 2 contingency tables categorized according to success and failure in recognition (RN) and success and failure in recall (RC). Such tables give 4 unconditional and 8 conditional probabilities. The relation between recognition and recall is generally expressed by the conditional probability of recognition given recall, P(RN IRC). This measure, which is also called recognition success, is of course the complement of P(nRN IRC) (i.e., recognition failure of recallable words). Tulving and Wiseman (1975) reported that recognition success was related to the unconditional probability of recognition, P(RN). On the basis of a metaanalysis of the results o...
