Sequential testing effects and the relationship between recognition and recognition failure

Tulving and Wiseman (1975) reported that there was a systematic relationship between the proportion of words recognized and the proportion of recallable words recognized. This relationship indicates a moderate positive covariation between recognition and recall across subject items, when each subject is given both types of test, recognition followed by recall. In this paper it is shown that the theoretical enterprise of trying to account for this relationship is fruitless unless the data are corrected for sequential testing effects. Evidence on the existence of these effects is reviewed, and then it is shown how they introduce a measure of dependency between recognition and recall. When the data are corrected, the theories proposed by Begg (1979) and Flexser and Tulving (1978) are shown to be poorly supported. The utility of the general enterprise of determining the relationship between recognition and recall by these means is also questioned.
