Previous research on graphic organizers has found that they facilitate memory for corresponding text. This study investigated why one type of graphic organizer (a matrix) may communicate inter concept relations more effectively than an outline or text. In three experiments, college students judged the accuracy of inter concept relations after they read a text and studied a matrix, an outline, or the text again. We also measured students' performance when study time was reduced and testing delayed. Results indicated that even when study time was reduced, viewing a matrix helped students make more accurate judgments of inter concept relations. We conclude that a matrix is more computationally efficient than an outline or text, enabling readers to compute inter concept relations more quickly and easily (Larkin & Simon, 1987), due to a communicative process called visual argument (Waller, 1981). However, this advantage disappeared when testing was delayed, which, ironically, may have been due to computational efficiency.
