This meta-analysis examined associations between the quantity and quality of parental linguistic input and children's language. Pooled effect size for quality (i.e., vocabulary diversity and syntactic complexity; k = 35; N = 1,958; r = .33) was more robust than for quantity (i.e., number of words/tokens/utterances; k = 33; N = 1,411; r = .20) of…

Previous research has revealed that distributional information obtained from child-directed speech could be informative for children when they are learning grammatical categories. Frequent frames are distributional units proposed by Mintz and explored by researchers in many languages with different typologies. This study investigated two…

Preliminary findings from a follow-up study of 33 children, assessed for their socioemotional development from 18 months of age, are presented. At 77 months, they were evaluated again in a laboratory context, recording on video a situation of discussion of a conflict with the caregiver and then coding these videos using the CIB instrument.…

Purpose: This study examined working memory in children with developmental language disorder (DLD). The overarching goal of this work was to integrate three primary processing-based hypotheses of DLD, (a) limited verbal working memory, (b) slowed processing speed, and (c) inefficient inhibition of interference, by using the…

This study aimed to understand the relationship between reception children's experiences of the coronavirus pandemic (COVID-19) and their academic achievement and socio-emotional development during their first year at school in September 2020 to July 2021. This was an exploratory study combining parent and school surveys with children's…

In the present study, children's early ability to organise words into sentences was investigated using the Weird Word Order procedure with Spanish-speaking children. Spanish is a language that allows for more flexibility in the positions of subjects and objects, with respect to verbs, than other previously studied languages (English, French, and…

There is growing evidence that the grammatical errors reflected in the speech of young children are often related to the nature of the input in the ambient language. Although theoretical frameworks differ in the degree to which input plays a role, there is acknowledgment that children require more input than previously assumed to resolve apparent…

In this exploratory study, we examined stress contrastivity within real word productions elicited via picture naming in 20 children with autism spectrum disorders (ASD) and 20 typical peers group-wise matched on age and vocabulary. Targets had a dominant pattern of lexical stress beginning with a strong-weak pattern (SW: 'caterpillar',…

The purpose of this study was to validate the Spanish version of the Family Involvement Questionnaire-Short Form (FIQ-SF) for use with Spanish-speaking families of children enrolled in early childhood education programs. This study examined the factor structure of the FIQ-SF and established criterion validity for the resulting FIQ-SF dimension…

Various speech metrics have been developed to assess and monitor phonological development in young children. Process Density Index (PDI) is one such measure employed to determine the severity of phonological errors and speech intelligibility. The present study explored the utility of PDI as a measure of phonological development in 756…

We investigated production of lexical stress in children with and without autism spectrum disorders (ASD), all monolingual Italian speakers. The mean age of the 16 autistic children was 5.73 years and the mean age of the 16 typically developing children was 4.65 years. Picture-naming targets were five trisyllabic words that began with a…

Pre-school children's engagement with activities in child-initiated play is taken to be an important mediating factor in their learning. The adult's role in supporting and enhancing children's play is an area of significant study. However, how children play when play is child-initiated, and how this maps to our assumptions and expectations about…

Our aim was to assess whether infants influence the quantity and quality of their mothers' speech to them and, in turn, whether this maternal speech influences children's later language. As 189 mothers interacted with each of their twins at age 0;5, we calculated the number of utterances, the proportion of sensitive utterances, and the proportion…

Purpose: The results of automatic machine scoring of the Index of Productive Syntax from the Computerized Language ANalysis (CLAN) tools of the Child Language Data Exchange System of TalkBank (MacWhinney, 2000) were compared to manual scoring to determine the accuracy of the machine-scored method. Method: Twenty transcripts of 10 children from…

Acquisition of an argument structure may be affected by the diversity of lexical types that appear in that structure (Conwell et al., 2011; Yang, 2016). Seventy-two 5- and 6-year-old English-speaking children completed a learning study where they were exposed to a novel argument structure and then tested on their ability to comprehend it. The…
