Single word items have usually been the unit of analysis for measuring L2 learners' vocabulary size, for designing word lists and for estimating word coverage of reading texts. However, what is lost in these estimates is the consideration of multiword expressions, such as idioms. To empirically test the assertion that the knowledge of single word…

Purpose: The purpose of our study was to test the hypotheses (a) that children with dyslexia have spoken word learning deficits primarily related to phonology and (b) that children with dyslexia and concomitant developmental language disorder (DLD) have word learning deficits related to both phonology and semantic processing when compared to peers…

Purpose: Vocabulary intervention should be guided by information from outcome measures that demonstrate whether the student has grown in depth or breadth of understanding of the taught words. However, there is a paucity of tools, to measure depth of vocabulary knowledge, that are available for clinical use. Method: The challenges of vocabulary…

Objectives: The aim of this study was to determine whether college students build their vocabularies by playing a serious game that incorporates principles of learning and memory. Design: This study used a single-site, prospective, randomized trial with 2 branches--immediate and delayed treatment. Outcome measures were obtained after a 1-month…

Autism spectrum disorder (ASD) is associated with deficient comprehension of figurative language and, specifically, idioms. Theories ascribe this to deficits in specific abilities (e.g., Theory of Mind [ToM]; executive functions [EF]; general language skills), but no comprehensive theory has resulted. This study investigated the differential…

Phonological selectivity is a phenomenon where children preselect which target words they attempt to produce. The present study examines selectivity in the acquisition of complex onsets and codas in English, and specifically in the acquisition of biconsonantal (CC) clusters in each position compared to triconsonantal (CCC) clusters. The data come…

Object names are a major component of early vocabularies and learning object names depends on being able to visually recognize objects in the world. However, the fundamental visual challenge of the moment-to-moment variations in object appearances that learners must resolve has received little attention in word learning research. Here we provide…

This article addresses the importance of teaching controversial issues, especially within elementary school contexts. In particular, the article explores the underlying elements of justice within controversies and demonstrates the way in which teachers might explore procedural justice within an elementary classroom.

Purpose: Children come to understand many words by the end of their 1st year of life, and yet, generally by 12 months, only a few words are said. In this study, we investigated which linguistic factors contribute to this comprehension-expression gap the most. Specifically, we asked the following: Are phonological neighborhood density, semantic…

This study used a Web-based naturalistic story-reading paradigm to investigate the impact of number of exposures on incidental acquisition and long-term retention of new meanings for known words by native English-speaking adults. Participants read one of four custom written stories in which they encountered novel meanings (e.g., a safe concealed…

Some researchers have argued that low-achieving students may never acquire sufficient levels of academic vocabulary to be successful in school without some form of explicit vocabulary instruction (e.g. Snow, Lawrence, & White, 2009). In this paper, I summarize the available data on the efficiency, in words learned per minute of instruction, of…

Spaced practice, or the distribution of practice opportunities across time, is a well-known and effective practice for improving retention. However, spaced practice is not effectively implemented in schools, perhaps as a result of a lack of educationally relevant research in the area. We conducted an educationally relevant investigation of the…

Several researchers have advocated explicit instruction of vocabulary in order to help students improve their reading comprehension, especially low-achieving readers who need to "catch-up" to their age peers. Very few studies, however, have attempted to compare the time efficiency of direct instruction to its alternatives. In this…

This paper suggests six areas of vocabulary research which the author believes would be fruitful for future research. They include (1) developing a practical model of vocabulary acquisition, (2) understanding how vocabulary knowledge develops from receptive to productive mastery, (3) getting lexical teaching/learning principles into vocabulary and…

As teachers worldwide struggle to serve an ever-increasing number of children and their families who do not speak the dominant language, the authors present a research-based scenario illustrating practices in Hungarian preschools.
