The primary aim of this study was to evaluate and compare alternative modalities and stimuli used to measure receptive vocabulary skills in autistic children who are minimally verbal. This study systematically compared participants' outcomes on three different receptive vocabulary assessment conditions: a low-tech assessment that used a stimulus…

Purpose: Oral narrative, or storytelling, skills may constitute a linguistic strength for African American children, with implications for academic and social well-being. Despite this possibility, few studies have examined individual differences in oral narrative skill among African American children. To address this gap in the literature, this…

Models are central to the practice and teaching of science. Yet people often fail to grasp how scientific models explain their observations of the world. Realizing the explanatory power of a model may require aligning its relational structure to that of the observable phenomena. The present research tested whether "relational…

Purpose: Literacy instruction at home and in school, in addition to child speech and language ability, plays an essential role in reading development. The relationship between these factors in children with developmental disabilities during preschool is important to identify and describe in order to develop and test interventions that target…

Inference making is fundamental to the construction of a coherent mental model of a text. We examined how vocabulary and verbal working memory relate to inference development concurrently and longitudinally in 4- to 9-year-olds. Four hundred and twenty prekindergartners completed oral assessments of inference making, vocabulary breadth, vocabulary…

Social science research often uses educational qualification as a signifier for characteristics such as abilities, earnings potential, and civic participation in adulthood. This study focused on two types of adult literacy students who were native speakers of English and identified words at the 3rd to 5th grade levels but differed in one key…

Purpose: Children with autism spectrum disorder (ASD) are at increased risk of experiencing difficulties with the development of literacy, including the emergent literacy skills recognized to underpin conventional literacy success. Comprehensive assessment is essential. Characteristics of ASD can make assessment challenging, and this can be…

Effective communication requires an understanding of the interlocutor's perspective. Being able to infer someone else's knowledge about a situation is a critical skill in any communication and social interaction. These abilities are part of Theory of Mind (ToM) skills and are known to be impaired in Down syndrome (DS). It therefore makes sense to…

This article examines factors that promote active multilingualism. For this purpose, the "Peabody Picture Vocabulary Test" was used with 48 children. Their results were linked to a parental questionnaire designed to evaluate the children's linguistic input in their immediate environment. The study shows that, besides a minimum amount of…

With regard to parents making communication approach decisions for their children with hearing loss, Crowe et al. (2014) suggested that key themes were: feasibility; sources of information; child characteristics; and, future opportunities. For children using cochlear implants (CI/s), the present study aimed to understand parental preferences…

Languages differ in their preferences for particular intensifying constructions. While intensifying adjectival compounds (IACs) (e.g. "ijskoud, ice-cold") are productively used to express intensification in Dutch and English, in French this construction is hardly productive. Consequently, French-speaking learners may encounter…

This study examines the English vocabulary development of 43 very young child English as a foreign language (FL) learners (age 3.2-6.2) in China. They were tested twice for vocabulary breadth (reception and production) and semantic depth (paradigmatic and syntagmatic vocabulary knowledge). The development of the English vocabulary knowledge…

In this thesis, I present three related papers that collectively investigate the instructional supports on screen and in the media viewing context that influenced English and heritage language vocabulary knowledge in DLLs. In study 1, I examine how specific pedagogical approaches used in educational media might benefit DLLs. In study 2, I…

Early, effective instruction to introduce both science vocabulary and general academic language may help children build a strong conceptual and linguistic foundation for later instruction. In this study, a design research intervention was employed to expose children to a variety of interrelated science content words to increase both the breadth…

In this paper the incidental language acquisition of 11-year-old Flemish children (n = 30) who have not received any formal English instruction is investigated. The study looks into children's English proficiency and the learner characteristics that can be associated with it. In order to measure the children's English proficiency, a receptive…
