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)

Guideposts for the librarian are established on how to guard against buying information which is duplicated too heavily to do the collection any good. (MF)

Criticizes past research on redundancy in television learning for its inconsistent definitions and ambiguous examples. Four areas of concern are considered: the meaning and use of the term; the nature of signs (iconic or digital) used in audio and visual communication; the subjectivity of interpretation; and differences in meaning between separate…

The impact of repeated and prolonged attempts at remembering on false memory rates was assessed in three experiments. Participants saw and imagined pictures and then made repeated recall attempts before taking a source memory test. Although the number of items recalled increased with repeated tests, the net gains were associated with more source…

The purpose of this study was to examine the redundancy effects obtained when spoken information was duplicated in writing during the learning of a multimedia document. Documents consisting of diagrams and spoken information on the development of memory models were presented to three groups of students. In the first group, no written text was…

The purpose of the present study was to determine whether the results obtained by Knowles et al. were a result of varying levels of redundancy or varying levels of other task parameters. (Author)

One of the most widely respected features of English orthography is its sequential redundancy. Its psychological reality is evidenced by the relative ease with which good readers can encode sequentially redundant nonwords as compared to arbitrary strings of letters. Its psychological importance is implicated by evidence that this advantage is…

This study investigated the effects on oral reading reversals of various contextual conditions ranging from no context to highly predictable contexts among white, middle-class, male first graders. The study was designed to demonstrate the relationship between language redundancy and reversals in a beginning reading population in order to suggest…

Examines effects of audio and visual redundancy on recall and story understanding in television news. Indicates that college students who viewed voice-over news stories varying in amount of redundancy showed higher auditory recall and story understanding in the high-redundancy condition than in the lower redundancy conditions. Visual recall shows…

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