Vocabulary size is a crucial early indicator of language development, for both monolingual and bilingual children. Assessing vocabulary in bilingual children is complex because they learn words in two languages, and there remains significant controversy about how to best measure their vocabulary size, especially in relation to monolinguals. This…

Improving social communication is a frequent goal of early autism services. However, it is unclear whether existing models of social communication align with the perspectives and priorities of key stakeholders, including parents, teachers, and expert clinicians. Stakeholder perspectives on social communication characteristics and priorities for…

During the second year of life, children acquire words and expand their receptive and expressive vocabularies at a rapid pace. At this age, toddlers' phonological abilities are also developing rapidly. The current study investigated the effect of phonological complexity of words on the order in which they are acquired, receptively and…

Purpose: This study explores whether the quality of parent-child interaction is associated with language abilities cross-sectionally and longitudinally up to preschool-age among children with developmental language disorder (DLD). Method: Participants were 97 monolingual children with DLD and their parents from the Helsinki Longitudinal SLI study,…

This study followed the development of Hong Kong Sign Language (HKSL) proficiency in 31 deaf bimodal bilingual children (kindergarten through Primary 6) over two years. The Hong Kong Sign Language Elicitation Tool (HKSL-ET) was used at three time points to elicit the production of agreement, classifier, modal, negation, and wh-question structures.…

This study examined the relationship between parental self-efficacy in parents of young deaf and hard-of-hearing (DHH) children and children's spoken language skills. A retrospective within-subjects study design was used that included 24 mother-child dyads with DHH children. Parental self-efficacy was assessed using the Scale of Parental…

Purpose: The purpose of this study was to evaluate if higher quantity, diversity, and grammatical informativeness of verb phrases in parent follow-in utterances (i.e., utterances that mapped onto child attentional leads) were significantly related to later expressive verb vocabulary in children with autism spectrum disorder (ASD). Method: We…

This investigation examined the role of students' social-emotional need satisfaction in relation to academic engagement and social-emotional skills. Among a sample of 501 secondary school students (and their parents/carers), several need satisfaction variables were examined: perceived social-emotional autonomy, perceived social competence,…

This study investigated the impact of training and coaching parents to use a higher level questioning strategy during shared reading time at home on the expressive language complexity of their young twice-exceptional children. Four parents were trained and coached to use higher level questions, based on the revised Bloom's taxonomy, with their…

Purpose: Cross-informant ratings are considered best practice for assessing children with autism spectrum disorder (ASD). However, informant disagreement often occurs, which can pose significant challenges to various aspects of clinical services. This study explored the degree of parent and speech-language pathologist (SLP) agreement on ratings of…

We investigated gesture production in infants at high and low risk for autism spectrum disorder (ASD) and caregiver responsiveness between 12 and 24 months of age and assessed the extent to which early gesture predicts later language and ASD outcomes. Participants included 55 high-risk infants, 21 of whom later met criteria for ASD, 34 low-risk…

Background: Individuals with autism spectrum disorder (ASD) have been characterized as having deficits in social communication and empathy which present difficulties in the areas of social reciprocity, sharing of emotions and developing and maintaining relationships. This study explores the associations between vocabulary, executive function…

Objective: There are very few measures of language development in spoken Greek that can be used with young deaf children. This study investigated the use of Cyprus Lexical List (CYLEX), a receptive and expressive vocabulary assessment based on parent report that has recently been adapted to Standard Greek, to measure the vocabulary development of…

Language abilities in adolescents with autism spectrum disorders (ASDs) are variable and can be challenging to ascertain with confidence. This study aimed to compare and evaluate different forms of language assessment: standardized language testing, narrative analysis and parent/teacher reports. 14 adolescents with ASD and 14 typically developing…

For more than 20 years, the MacArthur-Bates Communicative Development Inventory (CDI) and its adaptations for languages other than English have been used as reliable measures of infants' and toddlers' early receptive and productive vocabulary size. This article introduces the OZI, the Australian English adaptation of the MacArthur-Bates CDI, now…
