Purpose: Morphological regularities are an important feature of the English writing system, and exposure to written morphology may be key in the development of skilled word recognition. Our aim was to investigate children's experiences of written morphology by analyzing a large-scale corpus of children's reading materials spanning a target age…

The substantive component of construct validity requires a confrontation between empirical test results and content relevance. The Vocabulary Size Test (VST) has been extensively validated in terms of empirical results. Less is known, however, about expert judgments of content relevance. The VST was constructed and validated according to the…

Frequency is often the only variable considered when researchers or teachers develop vocabulary materials for second language (L2) learners. However, researchers have also found that many other variables affect vocabulary acquisition. In this study, we explored the relationship between L2 vocabulary acquisition and a variety of lexical…

This retrospective, exploratory investigation examined the types of target words that 66 children with/without word-finding difficulties (WFD) had difficulty naming, and the types of errors they made. Words were studied with reference to lexical factors (LFs) that might influence naming performance: word frequency, familiarity, length, phonotactic…

The two studies reported on in this paper examine the features of words that distinguish students' performances on vocabulary assessments as a means of understanding what contributes to the ease or difficulty of vocabulary knowledge. The two studies differ in the type of assessment, the types of words that were studied, and the grade levels and…

Previous research has shown that both dictation and speech-to-text (STT) software can increase the quality of writing for native English speakers. The purpose of this study was to investigate the effect of these modalities on the written composition and cognitive load of elementary school English language learners (ELLs). In a within-subjects…

Applied to the recognition of words in noise, the theory of the perceptual identification of complex stimuli provides a quantitative account of the proportions in which correct and erroneous responses of different frequencies will occur. (Author)

To set an optimal decision criterion on a test of recognition, a subject must estimate the degree to which they can discriminate previously studied from unstudied stimuli. To do so accurately, the subject must assess not only their mastery of the material but also the extent to which the distractors yield mnemonic evidence that makes them…

This study investigated the word recognition processes of readers of Chinese as a native language (L1) and as a second language (L2), focusing on the effects of two factors, word familiarity and word structure difficulty (complexity of orthographic symbol), on reading accuracy and response time. Subjects were in three groups: (1) 14 adult native…

A study of the acquisition of Swedish vocabulary by adult immigrants examined both the kinds and contexts of words learned. It found that simple and common words form the bulk of the vocabulary learned, and that frequency of input, complexity of input, and communicative need guide the learning process. Frequency refers to the frequency of both…

A study analyzing word characteristics that make them more easily translated from English to French (or vice versa) indicates that translation efficacy is most strongly influenced by the frequency of the word in the language, its familiarity, and the similarity of the French equivalent to the English word.
