Differences in socioeconomic status (SES) correlate both with differences in cognitive development and in brain structure. Associations between SES and brain measures such as cortical surface area and cortical thickness mediate differences in cognitive skills such as executive function and language. However, causal accounts that link SES, brain,…

Paradis' (2023) keynote article is a timely documentation of the ongoing shift in focus within childhood bilingualism research from investigating the factors that modulate majority or second language (ML/L2) attainment (Chondrogianni & Marinis, 2011) to understanding the sources of variation that lead to minority heritage language (HL)…

Individual differences in children's social communication have been shown to mediate the relationship between poor vocabulary or grammar and behavioural difficulties. Moreover, there is increasing evidence that social communication skills predict difficulties with peers over and above vocabulary and grammar scores. The essential social…

The development of the Multilingual Assessment Instrument for Narratives (MAIN) has no doubt contributed to prompting a renewed interest in children's narratives. This carefully controlled test of narrative abilities elicits a rich set of measures spanning multiple linguistic domains and their interaction, including lexis, morphosyntax,…

This case study longitudinally analyzes and describes the changes of attentional expressions in interchanges between a pair of fraternal twins, 1 deaf and 1 hearing, from the age of 10-40 months, and their Deaf family members. The video-observed attentional expressions of initiating and reestablishing interchange were grouped in 5 functional…

This study examines the beginning of the conceptual understanding of the first number-words and what role language can play in developing the notion of numbers. To that end, 2 1/2- and 3 1/2-year-old Basque and Spanish monolingual children's (N = 131) basic numeracy skills are analysed by means of two different experimental procedures: "Give-N"…

Although statistical learning and language have been assumed to be intertwined, this theoretical presupposition has rarely been tested empirically. The present study investigates the relationship between statistical learning and language using a within-subject design embedded in an individual-differences framework. Participants were administered…

The purpose of this study was twofold: (1) to evaluate the clinical utility of a verbal working memory measure, specifically, a nonword repetition task, with a sample of Spanish-English bilingual children and (2) to determine the extent to which individual differences in relative language skills and language use had an effect on the clinical…

Language development has long been associated with motor development, particularly manual gesture. We examined a variety of motor abilities--manual gesture including symbolic, meaningless and sequential memory, oral motor control, gross and fine motor control--in 129 children aged 21 months. Language abilities were assessed and cognitive and…

We present a neurocomputational model with self-organizing maps that accounts for the emergence of taxonomic responding and fast mapping in early word learning, as well as a rapid increase in the rate of acquisition of words observed in late infancy. The quality and efficiency of generalization of word-object associations is directly related to…

This study applies the Phonological Mean Length of Utterance measurement (PMLU; Ingram & Ingram, 2001; Ingram, 2002) to the data of five children acquiring Finnish and evaluates their phonological development longitudinally at four different age points: 2;0, 2;6, 3;0, and 3;6. The children's results on PMLU and related measures are discussed…

Word familiarity judgment may be important for word learning, yet little is known about how children make this judgment. We hypothesized that preschool-age children differ in the judgment criteria that they use and that this difference derives from individual differences in basic memory processes. Those who have superior phonological working…

Purpose: In this study, the authors investigated speech rhythm acquisition by bilingual Spanish-English-speaking children, comparing their performance with functionally monolingual peers in both languages and to monolingual and bilingual adults. Method: Participants included younger children (3;9 [years;months] to 4;5.15 [years;months.days]),…

The purpose of this study was to explore individual differences in children's tense onset growth trajectories and to determine whether any within- or between-child predictors could account for these differences. Twenty-two children with expressive vocabulary abilities in the low-average to below-average range participated. Sixteen children were at…

Results of a statistical study of language in 30 infants suggest that two acquisition styles (nominal/pronominal and referential/expressive) are developing in parallel. Only for children heavily emphasizing one strategy can a distinctive style be determined. Results at 20 months were only partially predictive of performance at 28 months. (MSE)
