It is reasonable to assume that information such as the fact that "a beaver is larger than a mouse" is part of the average college student's generalized world knowledge. The present experiments examine the processes whereby new information is integrated with this type of generalized world knowledge. During the study phase of these experiments, subjects were told, for example, that "A BOQ is larger than a TOF. A TOF is larger than a beaver. A mouse is larger than a PIV." During the test phase, subjects were asked to verify sentences pertaining to this information. Some sentences (e.g., "A TOF is larger than a beaver.") were actually presented and needed only to be retrieved. Other sentences (e.g., "A BOQ is larger than a beaver.") could be deduced using just the information presented during the study phase. Finally, some sentences (e.g., "A TOF is larger than PIV.") could be deduced only by using one's existing knowledge that a beaver is larger than a mouse. The factors affecting subjects' ability to respond correctly to this latter type of question were examined. (Author)
