Background: Speech and language therapists (SLTs) are increasingly engaging in school-based interventions targeting children with language difficulties. Collaborative work between teachers and SLTs has shown to be beneficial in fostering language development in all children. Both groups of professionals have different but complementary roles in…

The Lesson Study is a professional development model that places teachers at the center of practice and is used in the professional development of teachers who are currently in teacher training or currently in service. In Turkey, the professional development of teachers from various branches is also supported by using this model. However, no…

Previous research suggests that toddlers can rely on distributional cues in the input to track adjacent and nonadjacent grammatical dependencies. It remains unclear whether toddlers understand the hierarchical phrase structures that determine the corresponding grammatical dependencies. We addressed this question by testing toddlers on two…

This longitudinal study investigated the effects of maternal emotional health concerns, on infants' home language environment, vocalization quantity, and expressive language skills. Mothers and their infants (at 6 and 12 months; 21 mothers with depression and or anxiety and 21 controls) provided day-long home-language recordings. Compared with…

Language knowledge, age of acquisition (AoA), and stimulus intelligibility all affect gaze behavior for reading print, but it is unknown how these factors affect "sign-watching" among signers. This study investigated how these factors affect gaze behavior during sign language comprehension in 52 adult signers who acquired American Sign…

As part of a larger longitudinal project on the assessment of preschoolers' social-emotional development, children's social information processing (SIP) responses to unambiguous hypothetical situations of peer provocation were assessed for 239 preschoolers from Head Start and private childcare settings. SIP measurement focused on emotions children…

For children with normal hearing (NH), early communication skills predict vocabulary, a precursor to grammar. Growth in early communication skills of infants with cochlear implants (CIs) was investigated using the Early Communication Indicator (ECI), a play-based observation measure. Multilevel linear growth modelling on data from six ECI sessions…

Purpose: Auditory deprivation has downstream effects on the development of language and executive functioning (EF) in prelingually deaf children with cochlear implants (CIs), but little is known about the very early development of EF during preschool ages in children with CIs. This study investigated the longitudinal development of EF and spoken…

Classic studies of educational media have demonstrated that children can engage in quick, incidental word learning on the basis of a single exposure of a program. Since most words are learned from context, a lingering question has been whether the kind of contextual support affects word learning. Using a within-subjects design this study examined…

In this study, we examined how preschool students with language delays engaged in interactive dialogue during regular circle time and dramatic inquiry activities. Using frequency recording of three preschool students' linguistic engagement and multimodal analysis of classroom video data, this article explores how these students produced social,…

This research brings new evidence on early lexical acquisition in Wichi, an under-studied indigenous language in which verbs occupy a privileged position in the input and in conjunction with nouns are characterized by a complex and rich morphology. Focusing on infants ranging from one- to three-year-olds, we analyzed the parental report of…

How the construct of vocabulary is defined remains unclear although multiple theories have been put forth. In light of the lack of empirical work investigating the dimensionality of vocabulary knowledge in Chinese, the present study investigated the factor structure of Chinese print vocabulary in a sample of 111 Taiwanese children in Grades 1 and…

There is considerable controversy over the factors that shape infants' developing knowledge of grammar. Work with artificial languages suggests that infants' ability to track statistical regularities within the speech they hear could, in principle, support grammatical development. However, little work has tested whether infants' performance on…

The current study investigated language development of children residing in institutional care (IC) in Russia, compared to peers raised by biological family care (BFC). We used standardized behavioral testing (Preschool Language Scale-5, McArthur CDI), and an event-related potential picture-word matching paradigm. Children in IC significantly…

Classic studies of educational media have demonstrated that children can engage in quick, incidental word learning on the basis of a single exposure of a program. Since most words are learned from context, a lingering question has been whether the degree of contextual support affects word learning. Using a within-subjects design this study…
