This experiment compared the effects of pre-passage questions that quizzed information of different structural importance on college students' cued recall of expository prose passages. Among higher-vocabulary subjects, cued recall of detail information not specifically quizzed by the pre-passage questions was significantly greater in the condition in which pre-passage questions quizzed a detail unit than in the higher-level pre-passage question condition or the no pre-passage question condition, p < .05. These findings suggest that lowerlevel pre-passage questions do facilitate encoding of related details for subjects of certain ability levels, and that earlier findings showing a facilitation of free recall by higher-level pre-passage questions, but not by lower-level pre-passage questions, reflect primarily a retrieval phenomenon. However, the results also indicate that lower-level pre-passage questions are specific in their facilitative effects and do not promote memory for related main ideas.Recent research (Wilhite, 1983) has shown that the effect of pre-passage questions on the retention of indirect (i.e., non-quizzed) material depends on the structural importance of the information being quizzed. Specifically, Wilhite found that questions quizzing higher-level main ideas facilitated the free recall of related main ideas compared to a no-question control condition, whereas questions quizzing lower-level details in the passage did not facilitate recall of related main ideas. Neither higher-level nor lower-level questions significantly affected recall of indirect details.One possible interpretation of these results is that higher-level questions are more likely to encourage encoding of related information than are lowerlevel questions.
