This study developed an up-to-date listing of the most frequently occurring words used in written business communication. The purpose of this study was to provide word lists that will be of use to researchers, curriculum specialists, and textbook publishers in designing and evaluating curriculum materials. (CT)

Age-related differences in continuous recognition memory were assessed in adults. High and low frequency words were presented to the subject one at a time. No age difference was found in recognition latency or errors. Low frequency words were recognized faster and with higher accuracy. (Author)

Presents a conceptual model of certain processes that may underlie word selection. The model provides the basis of a mathematical expression that can calculate the total vocabulary available in English with an accuracy of 4.33 percent to 0.7 percent. (Author/CB)

Replies to the commentary by Olson and Salter on an article by Feldman and others, both reported in this issue. Maintains that the evidence does not support Olson's and Salter's conjecture that the source of age-distinctive lexical differences reported in the Feldman study is a simple function of word frequency.

A historicodevelopmental model of acquisition order of words was applied to 175 words comprising the Peabody Picture Vocabulary Test--Revised. A structural equation model demonstrates that the combination of date of entry into English, word length, polysemy, and frequency of use account for a substantial proportion of variance of acquisition…

Discussion of word frequency and keywords in text focuses on a method to estimate automatically the stability classes that indicate a word's popularity with time-series variations based on the frequency change in past electronic text data. Compares the evaluation of decision tree stability class results with manual classification results.…

An eye-movement reading experiment investigated whether the ease with which pronouns are processed is affected by the lexical frequency of their antecedent. Reading times following pronouns with infrequent antecedents were faster than following pronouns with frequent antecedents. We argue that this is consistent with a saliency account, according…

The experiment reported here investigated the sensitivity of concreteness effects to orthographic neighborhood density and frequency in the visual lexical decision task. The concreteness effect was replicated with a sample of concrete and abstract words that were not matched for orthographic neighborhood features and in which concrete words turned…

There is growing interest in the use of semantic collections in order to identify and analyse domain knowledge. This paper describes some technical issues to consider when contemplating research which incorporates small-to-medium domain-specific word sets. The purpose of the corpus construction described was to provide an external word collection…

The Klein effect (G. S. Klein, 1964) refers to the finding that high-frequency words produce greater interference in a color-naming task than low-frequency words. The present study used the Klein effect to investigate the relationship between frequency and age of acquisition (AoA) by measuring their influence on color naming. Two experiments…

This article evaluates 2 competing models that address the decision-making processes mediating word recognition and lexical decision performance: a hybrid 2-stage model of lexical decision performance and a random-walk model. In 2 experiments, nonword type and word frequency were manipulated across 2 contrasts (pseudohomophone-legal nonword and…

This article focuses on the development of vocabulary among English language learners. The author first defines what a "word" means, then discusses five aspects of vocabulary knowledge. Drawing on Swain (1993), the author identifies three main goals of vocabulary learning. The rest of the article is devoted to the description of six…

Previous research investigating the effects of contextualized and decontextualized tasks on vocabulary learning has focused on whether or not learners were able to gain knowledge of meaning and form. To date, research has generated little evidence indicating that context facilitates vocabulary learning. Decontextualized tasks tend to be equally or…

In this study we present a self-organizing connectionist model of early lexical development. We call this model DevLex-II, based on the earlier DevLex model. DevLex-II can simulate a variety of empirical patterns in children's acquisition of words. These include a clear vocabulary spurt, effects of word frequency and length on age of acquisition,…

Everyday speech is littered with disfluency, often correlated with the production of less predictable words (e.g., Beattie & Butterworth [Beattie, G., & Butterworth, B. (1979). Contextual probability and word frequency as determinants of pauses in spontaneous speech. "Language and Speech, 22," 201-211.]). But what are the effects of disfluency on…
