Abstract
An integrated scene schema memory model was proposed to provide an account of recall and recognition for five types of spatial relations. The integrated model assumes that recall involves retrieval processes where the retrieval of a relation depends on both its strength which is determined by the amount of attention it receives, and the degree to which it fits the contents of a scene schema. The memory predictions for the integrated model are derived from both the strength and degree of fit of a relation. There are two special cases of the integrated model, a retrieval mechanism account and an attention mechanism account. The retrieval mechanism account assumes that recall involves a retrieval process where the retrieval of relation only depends on its fit to the contents of a scene schema. The memory predictions for this case are only derived from the degree of fit between a given relation and the scene schema. The attention mechanism account assumes that recall involves a retrieval process where the retrieval of a relation only depends on the strength of the relation. The memory predictions for this case are only derived from the amount of strength that a relation has in memory. The integrated model includes two recognition memory accounts. One account assumes that recognition involves the same retrieval process as recall. Within the integrated model, this account makes predictions for recognition that follow the same pattern as the recall predictions made by the integrated model. Also, this account makes predictions for recognition that follow the same pattern as the recall predictions made within each of the two special cases. A second account assumes that recognition does not involve a retrieval process, and for both the integrated model and each of its two special cases, it predicts no recognition differences for the relations. Subjects read passages that described relations. Recall and recognition were tested after different retention intervals. The pattern of results supported the integrated model more than either of its two special cases.
