| Abstract: | Used linear structural equation modeling to test 2 models of declarative memory. A unitary model was compared with the semantic-episodic theory proposed by E. Tulving (e.g., 1972, 1983). The data consisted of performance scores of 300 Ss on 14 cognitive tests. The results of 2 sets of analyses suggest rejection of the unitary model but not the 2-factor model. Moreover, nested comparisons of the models revealed that the 2-factor model provided a significantly better fit to data than did the unitary model. Results support a division of declarative memory into memory for episodic information and memory for facts. This finding is discussed in terms of (1) different underlying memory systems mediating performance on semantic and episodic tests and (2) differences in the retrieval strategies that are required for accessing semantic and episodic information.
