Two experiments involving 285 college students investigated effects of signaling devices (headings, overviews, and summaries) on text memory. Signals produced recalls better organized by text topics. Results support a model in which signals influence readers' representations of a text's topic structure, which in turn guides recall of text content.…

Two experiments investigated some of the cognitive and affective causes of interest and liking. Results did not support the hypothesis that degree of surprise per se causes interest. The hypothesis that interest and liking arise from different causes was supported. (Author/LMO)

Effects on comprehension of a text structure used primarily in science and mathematics to present principles and associated proofs were studied for 70 undergraduates in 3 experiments. Results suggest that the usual proof-first structure is more difficult than a principle-first structure and results in less complete text representation. (SLD)
