There have been multiple reports over the last 3 decades that stimulus quality and word frequency have additive effects on the time to make a lexical decision. However, it is surprising that there is only 1 published report to date that has investigated the joint effects of these two factors in the context of reading aloud, and the outcome of that…

The study compared the relative benefits of word lists that were individualized for adolescent and adult subjects (N=10) using augmented communication to word lists selected from standard vocabulary sources. Findings indicated that individualized lists could represent a larger portion of the total communication sample in a relatively short list.…

Two studies examined word frequencies in toddlers' lexicons using the Language Development Survey (LDS). In Study 1, a high degree of consistency in LDS word frequencies was found in the lexicons of 758 24-month-olds. In Study 2, LDS word frequencies in 40 late talkers found both lexicon size and age of subject influenced the degree of consistency…

A common functional relationship among Lotka's law, Bradford's law, and Zipf's law is derived. The proof takes explicit account of the sequences of observed values of the variables by means of an index. This approach results in a more realistic and precise formulation of each law. (Author/EM)

The study attempted to (1) identify word sequences that occur frequently among 10 linguistically intact augmented communicators, (2) determine the communality with which the various augmented communicators use specific word sequences, and (3) evaluate the usefulness of word sequences in providing keystroke savings for uses of augmentative and…

Reviews aspects of the relationship between machine learning and information retrieval. Highlights include learning programs that extend from knowledge-sparse learning to knowledge-rich learning; the role of the thesaurus; knowledge bases; artificial intelligence; weighting documents; work frequency; and merging classification structures. (78…

Two word/nonword decision experiments were carried out to investigate differences in reading between congenitally blind children reading Braille and sighted children dealing with print. Three aspects of single-word recognition were studied: semantic processing, word frequency effects, and phonological recoding. (Author/RH)

The study generated a list of the 1000 most frequently used words by teachers of hearing impaired children in six primary grade classes. Results have implications for real time captioning systems of communication. An alphabetical list and a list ordered by frequency of use are appended. (DB)

Proposes split model for index term distribution in document set that uses rank function for high frequency terms and size function for low frequency terms; the point of transition is determined either empirically or by rule. Distributions to describe index term exhaustivity and term co-occurrence are considered briefly. (36 references) (EJS)

Discusses how current procedures for selecting/constructing equivalent texts may lead to error because of their specific limitations; proposes the utilization of micro-propositional analysis coupled with word-frequency lists and readability formulas for constructing "matching" texts; presents some procedures which researchers working in…

Investigated was the presence and role of cue words in word problems found in three mathematics textbooks series. The methodology and results of the study are presented. Lists of cue words for grades 3-6 are provided. (CW)

Analysis of the Bracken Basic Concept Scale (BBCS) indicated that all subtests except two (Quantity and Time) showed statistically significant correlations between item difficulty and frequency of concept words. Administration of the BBCS to 36 first graders revealed that most concept words showed expected item discrimination indices. (Author/JDD)

Reports algorithm for calculation of term discrimination values that is sufficiently fast in operation to permit use of exact values. Evidence is presented to show that relationship between term discrimination and term frequency is crucially dependent upon type of inter-document similarity measure used for calculation of discrimination values. (13…

This bibliography provides citations to studies of word/letter frequencies and vocabulary applications based on issues of word frequency. While the original intent was to gather information pertinent to developing communication board vocabularies for argumentative communication systems, these resources should be useful for a variety of word…

Identified are variables affecting performance of algebraic word problems for eighth graders. An appropriate readability level would seem necessary but not sufficient for student success. The structural variables used appeared to be good predictors of both the correct strategies and solving time. (Author/YP)
