This research evaluated the effects of asking subjects to create personal examples of target concepts on their ability to recall, classify, and apply their conceptual knowledge. Subjects were 48 undergraduates at a large midwestern university. All subjects studied a passage on four psychological principles that contained application adjunct questions preceded by definition adjunct questions inserted after selected paragraphs. Application questions asked subjects to identify novel examples of target concepts, and definition questions asked subjects to identify appropriate definitions. One-half of the subjects also received instructions after each set of adjunct questions to write down two personal examples of the target concept (i.e., elaborate their conceptual knowledge). Subjects were also separated into high and low ability groups based on their performance on a series of ability tests. The results indicated that elaboration produced a significant main effect and ability by treatment interaction only on the application of the target concepts to problemsolving scenarios. An ability main effect was found for number of teaching examples recalled, number of novel examples correctly classified, and for number of concepts correctly applied to problem-solving scenarios.
