According to the intersensory redundancy hypothesis (IRH), during early development, perception of nonredundantly specified properties is facilitated in unimodal stimulation as compared with bimodal stimulation. Later in development, attention becomes more flexible and infants can detect nonredundantly specified properties in both unimodal and…

THE THESIS OF THIS REPORT IS THAT REDUNDANT PARTS OF A SENTENCE MAY EITHER BE OMITTED OR REPLACED BY NONSENSE WORDS WITHOUT LOSS OF COMPREHENSION. AND IF THE NONSENSE WORDS ARE IN A LANGUAGE FOREIGN TO THE READER, THEIR CONSISTENT USE SHOULD EVENTUALLY EQUATE THEM TO EQUIVALENTS IN THE READER'S LANGUAGE. GRAMMATICAL STRUCTURE WILL ALSO BE ACQUIRED…

Argues that present work on the hidden curriculum is theoretically limited by a one-factor "theory of redundancy." Suggests a revised theory with (a) "Hot Curriculum"--which is largely based on the reward principle and (b) "Cold Curriculum"--based on the redundancy principle. (BR)

A 2,217-word news article was reduced 10 percent, 30 percent, and 50 percent by one of three reduction methods: word frequency, grammatical, and subjective. Reduction method had no effect on comprehension at the 10 percent and 30 percent reduction levels, but at the 50 percent level the subjective method produced better reading performance than…

A test was carried out to investigate the assumption that there is a significant level of redundancy between documents. The conclusions were that notional overlap exists, but there appear to be very few cases of extreme redundancy, and at the document level, there is little possibility of practical application. (Author)

The main advantage to the twenty-question technique is that it can be extended to low-redundancy material, which previous methods could not measure. (Author)

A new method is introduced for assessing children's component selection--i.e., the disposition to attend to a single feature of multifaceted stimuli. (Authors)

A stratified sample of 5,000 of the 40,000 purchase orders placed by 49 of the 59 University of London libraries revealed comparatively little duplication in the six month test period. (MM)

Experiment demonstrates that the reinforcing efficacy of visual feedback is related to its degree of redundancy. (WY)

Study supported by the Research and Development Center for Learning and Re-Education, University of Wisconsin, pursuant to contracts with the U.S. Office of Education.

Argues that both redundancy and propositional analysis (a strategy for analyzing meaning in a text) help to reveal the nature of the reader-text interaction and are two of the important missing elements in readability. (FL)

Van Allen (1996) supports a paradigm shift in how Americans think about education, from a view of school as hierarchy to school as continuum. While the relationship between elementary and secondary education is not always visible, teachers can model cooperative learning for students by working as a team across grade levels to solve problem,…

College students viewed a short multimedia PowerPoint presentation consisting of 16 narrated slides explaining lightning formation (Experiment 1) or 8 narrated slides explaining how a car's braking system works (Experiment 2). Each slide appeared for approximately 8-10 s and contained a diagram along with 1-2 sentences of narration spoken in a…

Two experiments examined the effect on recall of a response prefix, a redundant element emitted after the presentation of a memory series but before recall was completed. (Editor)

The quality of redundancy in language usage can be examined to determine its effect on communication efficiency. Semiotic redundancy, defined as the quantity of prolixity between semantic and pragmatic information, has the potential of reducing equivocation and error and, at the optimal level, provides maximum communication efficiency. Thus,…
