Partial pictures facilitated performance when presented with verbal information, but not when presented with the test questions. Sentence repetition facilitated performance only on questions presumed to reflect relatively shallow information processing. (Author/STS)

This paper is concerned with the role of redundancy in two important communication settings. Experiments 1 and 2 explored the effects of redundancy in a decoding task, where the respondent's goal is to identify the referent implied by a pair of descriptive messages. Experiment 3 assessed the extent to which people choose redundant messages when…

The information explosion has been blamed for the backlogs in libraries and information centers. Preliminary experiments reveal extensive dual publication between technical reports and journal articles as well as dual indexing and announcement. Methods of decreasing dual publication are suggested. (Author/NH)

Contends that redundancy increases information transmission and reception by (1) decreasing equivocation and error and (2) establishing memory traces and inhibiting forgetting. (PD)

Investigates whether audio/video redundancy improves memory for television messages. Suggests a theoretical framework for classifying previous work and reinterpreting the results. Suggests general support for the notion that redundancy levels affect the capacity requirements of the message, which impact differentially on audio or visual…

A study examined the relative contributions of semantic and non-semantic sources of redundancy in printed English, which play a central role in information processing models. Subjects, 40 undergraduate college students, were divided into two groups. One group predicted missing characters using English text, and the second group was required to…

The present experiments, in conjunction with prior findings that good and poor readers differ in letter search time by their ability to use spatial redundancy, suggest that processes involved in the component skill of letter identification cannot be considered trivial to the reading process.

The production of informationally redundant choices in a selection concept attainment task was investigated in relation to age and intelligence, using 62 adolescents aged 12:7--15:6 drawn from the lower middle ability range of a comprehensive school. (Editor)

THE FIRST OF A SERIES OF STUDIES DESIGNED TO INVESTIGATE THE SUITABILITY OF INSTRUCTIONAL MATERIALS WITH REGARD TO LEVELS OF DIFFICULTY IS REPORTED. THE STUDY ATTEMPTED TO DETERMINE WHETHER SOME RANGE OF DIFFICULTY MAXIMIZED THE AMOUNT OF INFORMATION STUDENTS GAIN AS A CONSEQUENCE OF READING INSTRUCTIONAL MATERIALS. IN ORDER TO FORM 129 PAIRS…

This book presents a three-part discussion of the causes and prevention of errors in foreign language learning with particular reference to English as a second language. The first part provides a survey of error analysis, defining what is meant by the term "error" and establishing a model of error production. Other terms explained in this section…
