Using online measures of familiar word recognition in the looking-while-listening procedure, this prospective longitudinal study revealed robust links between processing efficiency and vocabulary growth from 18 to 30 months in children classified as typically developing (n = 46) and as "late talkers" (n = 36) at 18 months. Those late talkers who…

This study examined the influence of morphological instruction in an eye-tracking English vocabulary recognition task. Sixty-eight freshmen enrolled in an English course and received either traditional or morphological instruction for learning English vocabulary. The experimental part of the study was conducted over two-hour class periods for…

This article describes a study conducted with four Kindergarten teachers and students. The researchers were the building's literacy specialist/reading teacher and a college professor teaching pre-service teachers on site at the school. This was a naturally evolving teacher research study generated from questions raised as children demonstrated…

Establishing classroom routines that provide students with the opportunities to learn and successfully apply the language of science is a daunting task. With minor variations, research has shown that effective and comprehensive vocabulary programs share four common elements: they are rich and varied language experiences; they teach well-selected…

Learning a new word involves integration with existing lexical knowledge. Previous work has shown that sleep-associated memory consolidation processes are important for the engagement of novel items in lexical competition. In 3 experiments we used spaced exposure regimes to investigate memory for novel words and whether lexical integration can…

Two ways of measuring change are presented and compared: A conventional "change score", defined as the difference between scores before and after an interim period, and a process-oriented approach focusing on detailed analysis of conceptually defined response patterns. The validity of the two approaches was investigated. Vocabulary…

This study investigated the hypothesis that vocabulary influences word recognition skills indirectly through "set for variability", the ability to determine the correct pronunciation of approximations to spoken English words. One hundred forty children participating in a 3-year longitudinal study were administered reading and…

The goal of this study was to examine how lexical association and discourse congruence affect the time course of processing incoming words in spoken discourse. In an event-related potential (ERP) norming study, we presented prime-target pairs in the absence of a sentence context to obtain a baseline measure of lexical priming. We observed a…

This experiment investigated whether individual differences in written language proficiency among university students predict the early stages of lexical retrieval tapped by the masked form priming lexical decision task. To separate the contributions of sublexical facilitation and lexical competition to masked form priming, the effects of prime…

Many words can be used flexibly: a book can be physically heavy, but also have provocative content, a "chicken" might live in a coop, but could also be tasty to eat. What do the uses of "polysemous" words such as these reveal about the structure of language and thought? Paper 1 examined 4-year-old children's representations of polysemous words…

This longitudinal study examined the predictive validity of the MacArthur Communicative Developmental Inventories-Short Form (CDI-SF), a parent report questionnaire about children's language development (Fenson, Pethick, Renda, Cox, Dale & Reznick, 2000). Data were first gathered from parents on the CDI-SF vocabulary scores for seventy-six…

Students with learning disabilities characteristically demonstrate unexpected underachievement and continued learning challenges in spite of appropriate instruction. Because reading is fundamental to competency of all future endeavors, reading interventions have been the focus of considerable public and professional attention. Intensive…

Existing reading assessments have increasingly been criticized by researchers, educators, and policy makers, especially regarding their coverage, utility, and authenticity (e.g., Magliano, Millis, Ozuru, & McNamara, 2007; Pellegrino, Chudowsky, & Glaser, 2001; Rupp, Ferne, & Choi, 2006). Specifically, there is concern that current…

Morphological skills have been associated with performance on multiple literacy outcomes. While growth in derived word knowledge has been documented during mid-elementary grades, little research has studied the development of knowledge of specific morphemes, separate from whole-word knowledge. This study examined the development of knowledge of a…

The goals of this study were to examine (a) whether extratextual vocabulary instructions embedded in electronic storybooks facilitated word learning over reading alone and (b) whether instructional formats that required children to invest more effort were more effective than formats that required less effort. A computer-based "assistant" was added…
