Reviews models of reading performance as an organizing framework for understanding findings from empirical studies of text and reader factors. Reviews numerous empirical studies of text design and reader variables and their effects on comprehension. Aims to help readers understand this research and its implications in document design decisions.…

Investigates the relationship of specific semantic and syntactic text characteristics to what information readers recall. Confirms that readers are more likely to recall more versus less important information and information in clauses, independent clauses, and first paragraphs. Suggests how writers can use these findings to help readers retain…

Presents a review of the literature on reader-focused text evaluation. Gives an account of the document characteristics that can be evaluated and considers the possible functions of evaluations making a distinction between verifying, troubleshooting, and choice-supporting research. Presents an overview of methods appropriate for the various…

Proposes that readability formulas cannot predict text difficulty. Presents results of an experiment designed to demonstrate that "text difficulty" is determined by individual differences (perception) and not by the objective qualities of a text. (NH)

Indicates that both novices and experts considered (1) definitions more important than facts, though novices applied this rule more strongly, and (2) information high in the passage hierarchy more important than lower level information. Finds that hierarchical level has a greater effect on the perceived importance of definition than facts. (JD)

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)

Two studies examined the validity of a model of procedural document processing, and the relationships among document features, reader characteristics, and successful completion of a button-sewing task. The first study tested three information sources. Subjects were 12 seventh-grade, 12 tenth-grade, and 12 adult students who used 2 commercially…

Reviews previous research on the effects of signals (structural cues that announce or emphasize content or reveal content relationships) on readers' comprehension of expository prose. Concludes that inconsistent results are due to inadequate methodologies that fail to control for confounding variables, such as text length and difficulty, topic…

Investigates readers' response patterns to informative documents. Finds that readers make direct confirmations and positive comprehension evaluations when information is conveyed clearly; when understanding is impaired, readers seek more clearly established relationships in the text. Concludes that readers make evaluative suggestions that…

Investigates the role of signaling (structural cues that announce or emphasize content or reveal content relationships) in helping good readers comprehend expository text. Finds that signals do improve a reader's comprehension, particularly comprehension two weeks after the reading of a passage and comprehension of superordinate and superordinate…

All language use, including written school language, is rhetorical and communicative, and both composing and reading textbooks are rhetorical situations that include interactions and transactions. One issue concerning text characteristics is whether the diverse parts that authors play influence how students learn from their books and respond to…

Argues that comprehension is a problem-solving activity and that different problem-solving schemata exist for different types of texts, both narrative and expository. Suggests that good comprehension occurs when there is a match between the author's schemata and that of the reader, creating a dialogue between the writer and the reader. (JK)
