Purpose: Although conversational recast treatment is generally efficacious, there are many ways in which the individual components of the treatment can be delivered. Some of these are known to enhance treatment, others appear to interfere with learning, and still others appear to have no impact at all. This study tests the potential effect of…

Purpose: The study examined the use of percent grammatical utterances (PGUs) for assessing grammatical skills in Mandarin-speaking 3-year-old children. Method: Participants were 30 Mandarin-speaking 3-year-olds with typical development. Language samples were collected in two visits for each child using a picture description task. Children were…

There is substantial evidence that children's apparent omission of grammatical morphemes in utterances such as "She play tennis" and "Mummy eating" is in fact errors of commission in which contextually licensed unmarked forms encountered in the input are reproduced in a context-blind fashion. So how do children stop making such…

This study aims to identify the phonological error patterns of normally developing children who speak colloquial Jordanian Arabic dialect and to provide normative data for the age of suppression for each phonological error pattern. One hundred fifty-four normally developing children (68 females and 86 males) ranging from 3 to 6.5 years were…

In numerical cognition research, the operational momentum (OM) phenomenon (tendency to overestimate the results of addition and/or binding addition to the right side and underestimating subtraction and/or binding it to the left side) can help illuminate the most basic representations and processes of mental arithmetic and their development. This…

Purpose: Sign language, like spoken language, incorporates phonological and articulatory (or motor) processing components. Thus, the learning of novel signs, like novel spoken word forms, may be problematic for children with developmental language disorder (DLD). In the present work, we hypothesize that phonological and articulatory deficits in…

Errors are essential for emergent literacy learning because they reveal the gaps in young children's knowledge. The ways in which teachers respond to these errors can have important implications for children's knowledge building; yet, there is limited information for teachers about how to effectively respond to children's errors in emergent…

This study examined how inferences about epistemic competence and generalized labeling errors influence children's selective word learning. Three- to 4-year-olds (N = 128) learned words from informants who asked questions about objects, mentioning either correct or incorrect labels. Such questions do not convey stark differences in informants'…

Background: The conversational speech of most children can be understood by people outside the family by the time they reach 4 years. However, for some children, speech sound disorders (SSDs) persist into their early school years, and beyond, despite adequate hearing, oromotor function, and language learning opportunities. One explanation for…

Background: Bilingual assessment is particularly difficult in the very first period of children's second language (L2) exposure. This exploratory, longitudinal study examined L2 learning after 1 and 2 years of L2 exposure by young immigrants and how it is affected by their age at first exposure to the L2 (AoE). Method: Participants were 18…

Purpose: We evaluated whether children whose inaccurate /[voiced alveolar approximant]/ productions showed evidence phonetic differentiation with /w/ at 3.5-4.5 years of age improved in /[voiced alveolar approximant]/ production over the next year more than children whose inaccurate productions did not show evidence of such differentiation. We…

Dynamic Measurement Modeling (DMM) is a recently-developed measurement framework for gauging developing constructs (e.g., learning capacity) that conventional single-timepoint tests cannot assess. The current project developed a person-specific DMM Trajectory Deviance Index (TDI) that captures the aberrance of an individual's growth from the…

Purpose: Cleft palate is one of the most common birth defects in the United States. Most of these children receive speech therapy by preschool and school-based clinicians. The purpose of this article is to provide a comprehensive tutorial for speech-language pathology assistants (SLPAs) regarding treatment techniques and principles for children…

Young children's early repeating patterning abilities are important foundations for their later mathematical development. Prior studies on young children's repeating patterning abilities have been conducted exclusively in developed countries differing in economic, societal, and educational characteristics from developing countries. In this study,…

Purpose: The aim of this study was to examine the relationship between types of speech errors produced by children with speech sound disorders (SSD) and children with typical speech and language development (TD) and phonological awareness (PA) skills. Method: Participants were 40 children, half with SSD and half with TD, ages 4 and 5 years. They…
