The Search of Associative Memory (SAM) model for recall (Raaijmakers & Shiffrin, 1981b) is extended by assuming that a familiarity process is used for recognition. The recall model posits cue-dependent probabilistic sampling and recovery from an associative network. Our recognition model is closely related to the recall model because the total episodic activation due to the context and item cues is used in recall as a basis for sampling and in recognition to make a decision. The model, formalized in a computer simulation program, correctly predicts a number of findings in the literature as well as the results from a new experiment on the wordfrequency effect."A critical problem of long standing in psychological study of memory is concerned with the relation between recall and recognition. In what sense are they the same, and in what sense are they different?" (Tulving & Watkins, 1973, p. 739).This article is a preliminary attempt to formulate a theory that describes in detail the relationship between recall and recognition. The relationship is realized in a computer simulation model, and the model's predictions are checked against existing data as well as data generated in our laboratory. The model for recognition is related mathematically and logically to the Search of Associative Memory (SAM) theory of memory retrieval that has
