Purpose: This study examined the psychometric properties of the Preschool Language Scales---Fifth Edition (PLS-5 English) among preschool children from low--socioeconomic status (SES) families. Method: The PLS-5 was administered individually to 169 3- to 4-year-old children enrolled in Head Start programs. We carried out a Mokken scale analysis…

Children with hearing loss often attend inclusive preschool classrooms aimed at improving their spoken language skills. Although preschool classrooms are fertile environments for vocal interaction with peers, little is known about the dyadic processes that influence children's speech to one another and foster their language abilities and how these…

We report two experiments on the emission of questions to request the names of unfamiliar stimuli by preschoolers. In the first experiment, 19 preschoolers with and without disabilities served as participants. Experiment 1 was a descriptive analysis of whether or not the 19 participants asked questions about unfamiliar pictures and objects in…

We examined how educating paraprofessionals in preschool classrooms on dialogic reading (DR) affected their storybook reading and effects on children's single word vocabulary. Through a single-case multiple-probe across participants design including four paraprofessionals and eight preschool children, we identified a functional relation between…

Purpose: This study was conducted in a large Midwestern metropolitan area to examine the language environments at home and in center-based childcare for young children who are living in poverty. We compared child language use and exposure in the home and childcare settings using extended observations with automated Language Environment Analysis to…

A repeated acquisition (RA) design was used to compare the effectiveness of research-based instruction embedded in repeated storybook reading facilitated by an adult or tablet application (app) on the vocabulary knowledge of six preschool children. All participants selected scored below the 40th percentile on the "Preschool Language…

The purpose of this study was to examine the relationship between language skills and behavioural problems and the potential moderating role of the quality of classroom emotional support in this relationship among 242 preschool children from low-income families. The "Preschool Language Scale-5" was administered individually to each…

The purpose of this study was to examine the longitudinal, bidirectional relationship between language skills and behavior problems in a sample of 194 preschool children enrolled in Head Start programs. Children were individually assessed using the "Preschool Language Scale-5," and teachers completed the "Child Behavior…

The purpose of this study was to explore the use of code-switching in the narratives of dual-language Latino preschoolers, specifically by examining its incidence, types, functions, and grammaticality. Previous work has investigated code-switching in younger children and in older children and adults, but relatively little work has investigated…

Data-driven decision making (DDDM) helps educators identify children not responding to intervention, individualize instruction, and monitor response to intervention in multitiered systems of support (MTSS). More prevalent in K-12 special education, MTSS practices are emerging in early childhood. In previous reports, we described the Making Online…

Previous research mainly with monolingual children shows a positive relationship between English skills and emotion regulation. No study to date has examined if or how learning of grammatical morphemes might be associated with emotion regulation among bilingual preschoolers. This study examined how Mandarin-English bilingual preschoolers performed…

Closing the vocabulary gap for young children at risk for reading and language delays due to low socioeconomic status may have far reaching effects, as the relationship between early vocabulary knowledge and later academic achievement has been well-established. Vocabulary instruction for young children at risk for reading and language delays…

The United States is becoming a more culturally and linguistically diverse nation. This is especially true when we look at the youngest generation of learners. This growing diversity increases the need to accurately identify young children as dual language learners (DLLs) prior to kindergarten. Ensuring educators have a strong understanding of…

Children's frequency of stuttering can be affected by utterance length, syntactic complexity, and lexical content of language. Using a unique small-scale within-subjects design, this study explored whether language samples that contain more stuttering have (a) longer, (b) syntactically more complex, and (c) lexically more diverse utterances than…
