This study examined the joint effects of home environment and center-based child care quality on children's language, communication, and early literacy development, while also considering prior developmental level. Participants were 95 children (46 boys), assessed as toddlers (mean age = 26.33 months; Time 1) and preschoolers (mean age = 68.71…

Recent studies on the acquisition of semantics have argued that knowledge of the universal quantifier is adult-like throughout development. However, there are domains where children still exhibit non-adult-like universal quantification, and arguments for the early mastery of relevant semantic knowledge do not explain what causes such…

Acquisition of regular inflectional suffixes is an integral part of grammatical development in English and delayed acquisition of certain inflectional suffixes is a hallmark of language impairment. We investigate the relationship between input frequency and grammatical suffix acquisition, analyzing 217 transcripts of mother-child (ages 1 ; 11-6 ;…

Until recently, the challenges inherent in measuring comprehension have impeded our ability to predict the course of language acquisition. The present research reports on a longitudinal assessment of the convergent and predictive validity of the MacArthur-Bates Communicative Development Inventories: Words and Gestures (CDI: WG; Fenson et al.,…

Data from 492 Italian infants (8-18 months) were collected with the parental questionnaire MacArthur Bates Communicative Development Inventories to describe early actions and gestures (A-G) "vocabulary" and its relation with spoken vocabulary in both comprehension and production. A-G were more strongly correlated with word comprehension…

The aim of this study was to investigate the impact of Socio-Economic Status (SES) on Hebrew-speaking children's developing ability to pluralize nouns and mark adjectives in agreement with them. Participants were 180 gradeschool children from mid-high SES and 180 peers from low SES, in six consecutive grade levels. The task consisted of 32…

How do children develop the mapping between prosody and other levels of linguistic knowledge? This question has received considerable attention in child language research. In the present study two experiments were conducted to investigate four- to five-year-old Mandarin-speaking children's sensitivity to prosody in ambiguity resolution. Experiment…

This study examined on-line processing of Swedish sentences in a grammaticality-judgement experiment within the framework of the Competition Model. Three age groups from 6 to 11 and an adult group were asked to detect grammatical violations as quickly as possible. Three factors concerning cue cost were studied: violation position (early vs. late),…

Intensive Speech and Language Therapy (SLT) training courses for Early Childhood Educators (ECEs) can have a positive effect on their use of interaction strategies that support children's communication skills. The impact of brief SLT training courses is not yet clearly understood. The aims of these two studies were to assess the impact of a brief…

In the current study we investigate whether 2- and 3-year-old German children use intonation productively to mark the informational status of referents. Using a story-telling task, we compared children's and adults' intonational realization via pitch accent (H*, L* and de-accentuation) of New, Given, and Contrastive referents. Both children and…

This article traces the historical foundations of the identification of language disorders in childhood through an international perspective. It describes the development of the profession of speech-language pathology, initially in Western Europe and later in North America. The roles played by key researchers in the area of child language are…

The aim of this study was to determine whether children with specific language impairment (SLI) are sensitive to completion cues in their comprehension of tense. In two experiments, children with SLI (ages 4 ; 1 to 6 ; 4) and typically developing (TD) children (ages 3 ; 5 to 6 ; 5) participated in a sentence-to-scene matching task adapted from…

It is generally accepted that talk enriches children's interpretations of texts in literature circle discussions. However, the nature of that talk and exactly how it facilitates interpretation of texts has not been much analysed. This article describes some work undertaken with a class of Scottish children, aged 9-10, to introduce them to the idea…

Relations between mothers' tendency to comment appropriately on their 8-month-olds' internal states (mind-mindedness) and children's behavioral difficulties (Strengths and Difficulties Questionnaire) at ages 44 and 61 months were investigated in a socially diverse sample (N = 171, 88 boys). Controlling for maternal depressive symptoms, perceived…

The goal of this study was to examine the influence of part-word phonotactic probability/neighborhood density on word learning by preschool children with normal vocabularies that varied in size. Ninety-eight children (age 2 ; 11-6 ; 0) were taught consonant-vowel-consonant (CVC) nonwords orthogonally varying in the probability/density of the CV…
