Reports on three experiments that: (1) extend the findings of Scarborough et al. (1977) that exposure to single words facilitates lexical judgments of single words, and (2) suggest that recency of exposure may contribute to word "frequency" effects in reading and in learning from written material.

Several experiments investigated the effect of word length on recognition thresholds for both familiar English words and unfamiliar pseudowords, the thresholds measured both with and without a stimulus mask. (Editor)

Shows how language processing is intimately tuned to input frequency. Examples are given of frequency effects in the processing of phonology, phonotactics, reading, spelling, lexis, morphosyntax, formulaic language, language comprehension, grammaticality, sentence production, and syntax.

Considers the proposed developmental sequence of formula>low-scope>pattern>construction in the emergence of future expression in a longitudinal study of adult learners of English as a Second Language. Findings suggest that the use of formulaic expressions may be subject to individual variation and that learners may use formulaic…

Describes the design of an automatic indexing system that is based on statistical techniques and expert system technology. Highlights include system architecture; the derivation of topic indicators, including word frequency; experimental results using documents from ERIC; the effects of stemming; and the identification of characteristic…

This article contrasts aphasic patients' performance of word naming and lexical decision with that of intact college-aged readers. We discuss this contrast within a framework of self-organization; word recognition by aphasic patients is destabilized relative to intact performance. Less stable performance shows itself as an increase in the…

Variations in the amount and nature of early language to which children are exposed have been linked to their subsequent ability (e.g. Huttenlocher, Haight, Bryk, Seltzer & Lyons, 1991; Hart & Risley, 1995). In three computational simulations, we explore how differences in linguistic experience can explain differences in word learning ability due…

Analyzing word frequency in six complete texts, a study investigated how vocabulary can be used to define texts. The texts included three stories from 5th and 6th grade readers, selections from literature anthologies for 8th grade and 12th grade students, and a magazine essay for adults. Results indicated that if particular words occur frequently…

A study investigated the exophoric function of the pronouns "it, they, he, she" and related forms in four English conversations. It analyzed the frequency and characteristics of the occurrence of those exophoric pronouns and found that they were much less frequent than endophoric pronouns. It also found that the exophoric pronoun groups…

While interest in second language vocabulary knowledge has increased, vocabulary testing remains largely confined to the quantitative measurement of discrete items. More qualitative measures are needed to assess how well particular words are known. Research has characterized word knowledge in two ways: as a set of components or aspects, and as an…

To determine if measures of the frequency of English root words can serve as reliable predictors of knowledge of those words, a 98-item multiple choice vocabulary test, in which all of the items were English root words, was administered to 46 third graders and 45 fourth graders. The percentage of correct responses for the words was correlated with…

An alternative to the standard "rule based" account of a child's acquisition of the past tense in English is presented in this paper. While the rule based assumption suggests that children typically pass through a three-phase acquisition process in which they first learn past tense by rote, then learn the past tense rule and overregularize, and…

Compilation of a list of the most common phrases used in reading was begun with the rationale that the quick recognition of phrases would facilitate reading comprehension. These first efforts showed that categorizing phrases by parts of speech did not provide acceptable levels of accuracy. The system that was effective, however, used a computer…

To determine the number of distinct words in printed school English, a study analyzed a 7,260 word sample from the "Word Frequency Book" prepared by J. B. Carroll, P. Davies, and B. Richman. Projecting from the sample to the total vocabulary of school English, the best estimate was that it contained about 88,500 distinct words. Furthermore, for…
