The use of schematic knowledge about sources in source monitoring.

Source monitoring refers to mental processes leading to attributions regarding the origin of information. We tested Johnson, Hashtroudi, and Lindsay's (1993) assumption that prior source-relevant knowledge is used in some source-monitoring tasks. In two experiments using different domains of schematic knowledge, two sources presented information that was expected for one source and somewhat unexpected for the other. In a later source-monitoring test, participants decided whether items had been presented by Source A, by Source B, or were new. The results of both experiments show that source identification is better for expected items than for somewhat unexpected items. Multinomial modeling analyses revealed that when participants do not remember the source of information, they guess that it was presented by the expected source. These results provide evidence for the claim that source monitoring can be based on prior knowledge and support a guessing hypothesis.

Scene schemata in memory for spatial relations.

Two schema-based hypotheses were developed and tested regarding recall for the following five types of spatial relations: scene-expected relations, two types of scene-unexpected relations, and two types of scene-irrelevant relations. In two experiments, subjects read relations that were described in passages and then recalled the passages. An attention hypothesis states that the amount of attention directed to a relation increases as the relation increasingly deviates from the schema. This hypothesis predicts high recall for unexpected relations, intermediate recall for irrelevant relations, and low recall for expected relations. A retrieval hypothesis states that a schema guides the search for schema-related information. This hypothesis predicts high recall for expected relations, intermediate recall for one type of scene-unexpected relation and one type of scene-irrelevant relation, and low recall for the remaining types of relations that are unexpected and irrelevant. The results of Experiment 1 supported certain predictions of both hypotheses, and the results of Experiment 2 supported the retrieval hypothesis.
