Processes of inference during sentence encoding

Abstract

Four experiments were designed to determine whether implicit instruments are "computed" and stored during sentence encoding. Subjects read pairs of related sentences and indicated when they understood the second member of each pair. In Experiment 1, response times were longer for test sentences that, relative to the antecedent, mentioned implicit rather than explicit instruments. Experiment 2 revealed this difference to be stable over a range of reading times and two phases of practice. The results were interpreted as suggesting that the inferences in question are not computed, or at most, are partially drawn during encoding In Experiment 3, the procedure was employed to distinghish four degrees of relation between propositions and the inferences they permit. Experiment 4 examined the agent, patient, and instrument cases. It was shown that subjects need more time to verify both true and false inference tests than to verify their direct counterparts. © 1979 Psychonomic Society, Inc.
