Talker variation and word learning

Purpose This prologue introduces the LSHSS Forum: Vocabulary Across the School Grades. The goals of the forum are to provide an overview of the importance of vocabulary to literacy and academic achievement, to review evidence regarding best practices for vocabulary instruction, and to highlight recent research related to word learning with students across different grade levels. Method The prologue provides a foundational overview of vocabulary's role in literacy and introduces the topics of the other ten articles in the forum. These include clinical focus articles, research reviews, and word-learning and vocabulary intervention studies involving students in elementary grades through college. Conclusion Children with language and reading disorders experience specific challenges learning new words, but all students can benefit from high-quality vocabulary instruction. The articles in this issue highlight the characteristics of evidence-based vocabulary interventions for children of different ages, ability levels, and language backgrounds and provide numerous examples of intervention activities that can be modified for use in individual, small-group, or large-group instructional settings.

Novel Word Learning

Purpose This study tested the effects of background speech babble on novel word learning in preschool children with a multisession paradigm. Method Eight 3-year-old children were exposed to a total of 8 novel word–object pairs across 2 story books presented digitally. Each story contained 4 novel consonant–vowel–consonant nonwords. Children were exposed to both stories, one in quiet and one in the presence of 4-talker babble presented at 0-dB signal-to-noise ratio. After each story, children's learning was tested with a referent selection task and a verbal recall (naming) task. Children were exposed to and tested on the novel word–object pairs on 5 separate days within a 2-week span. Results A significant main effect of session was found for both referent selection and verbal recall. There was also a significant main effect of exposure condition on referent selection performance, with more referents correctly selected for word–object pairs that were presented in quiet compared to pairs presented in speech babble. Finally, children's verbal recall of novel words was statistically better than baseline performance (i.e., 0%) on Sessions 3–5 for words exposed in quiet, but only on Session 5 for words exposed in speech babble. Conclusions These findings suggest that background speech babble at 0-dB signal-to-noise ratio disrupts novel word learning in preschool-age children. As a result, children may need more time and more exposures of a novel word before they can recognize or verbally recall it.

Abstract The purpose of this article is to look at the word learning skills in sequential bilingual children—children who learn two languages (L1 and L2) at different times in their childhood. Learning a new word is a process of learning a word form and relating this form to a concept. For bilingual children, each concept might need to map onto two word forms (in L1 and in L2). In case studies, I present 3 typically developing Hmong-English bilingual preschoolers' word learning skills in Hmong (L1) and in English (L2) during an 8-week period (4 weeks for each language). The results showed gains in novel-word knowledge in L1 and in L2 when the amount of input is equal for both languages. The individual differences in novel word learning are discussed.
