An experiment compared readers' use of analogic and pictorial illustrations for understanding and remembering complex instructional text. High school students (N = 102) read procedural texts under six analogic and pictorial illustration conditions and attempted to apply the texts' content in an applied performance task. Two weeks later students were evaluated on their attempts to perform the same task from memory. Pictures proved helpful for both immediate performance and delayed performance. Analogy was helpful for delayed performance but only slightly more helpful on immediate performance. Results are discussed in terms of apparent functions of analogies and pictures.To comprehend texts and learn from them, effective readers deploy the images they generate in reading with some deliberation, resorting to a number of strategies for increasing the meaning of the content and for remembering it as they find it necessary. By organizing images produced in response to a text, readers can create fictions to help them understand the text's content. These may take the form of direct or symbolic fictions and may turn upon highly imaginative creations which sometimes personify what is not human, sometimes animate the inanimate (cf. Gordon, 1961;Khatena, 1983). The fictions readers image occur primarily as incipient visual representations (Iser, 1972, Kosslyn, 1980Sless, 1981). To form a fiction, readers structure images so that they cor-63 64

By variously organizing them as if into placeholders in rhetorical analogies (as in patterns A:B::B:C, A:B::C:D, etc.), readers can structure images into heuristic fictions useful for discovery and invention (DeBono, 1970; Gordon, 1961;Vaihinger, 1924Vaihinger, /1935. The success with which readers form useful fictions may well depend upon readers' comprehension and memory demands and the extent to which text features help readers meet those demands. When the demands are to gain spatial orientation, pictures may prove helpful (Dean & Enemoh, 1983;Dean & Kulhavy, 1981). When the demands are to gain mnemonic advantage, anologies may be in order (Honeck, Riechmann, & Hoffman, 1975). When the comprehension demands are both spatial and mnemonic, a combination of pictures and analogies might work best (Mayer, 1975;Royer & Cable, 1976).Research on readers' use of illustrative devices in texts suggests overlapping and perhaps complementary functions of pictures and analogies. Mayer (1975) found that analogies as well as schematic drawings improved readers' interpretation of a passage on computer operations, but he drew no conclusions about the differential contributions of either. In a related vein, Royer and Cable (1976) found that both analogies and pictures facilitated recall on a transfer task, but, again, their study did not permit any differentiation of pictures from analogies in their use by readers.
