Purpose: The goal of this work was to examine the semantic and syntactic properties of the vocabularies of autistic and non-autistic infants and toddlers to see if children in these two groups know different kinds of words. We focused on both receptive and expressive vocabularies. For expressive vocabulary, we looked only at the "active"…

Purpose: Little is known about the specific nature of language abilities of autistic adolescents and young adults with language impairment (LI), limiting our knowledge of developmental trajectories and ability to develop efficacious speech/language supports. An important first step is establishing proof of concept of identification of LI in this…

Purpose: This study examined two markers of language impairment (LI) in a single experiment, testing sentence imitation and grammatical morphology production using an imitation task with masked morphemes. One goal was to test predictions of the morphological richness account of LI in Czech. We also tested the independent contributions of language…

Purpose: The fine-tuning of linguistic prosody in later childhood is poorly understood, and its neurological processing is even less well studied. In particular, it is unknown if grammatical processing of prosody is left- or rightlateralized in childhood versus adulthood and how phonological working memory might modulate such lateralization.…

This study examined linguistic development among both intermediate and advanced college-level second language (L2) learners during short-term study abroad summer programs in Spain. Participants completed a measure of overall proficiency, as well as assessments of receptive grammatical (morphosyntactic) and lexical (semantic) abilities at the…

In this study, we explored the role of emerging inhibitory control skills in language acquisition in 62 typically developing children aged 24-32 months and investigated whether early inhibitory control skills are longitudinally associated with language outcome. Specifically, we focused on two different inhibitory processes that develop…

When threatened with ostracism, children attempt to strengthen social relationships by engaging in affiliative behaviors such as imitation. We investigated whether an experience of ostracism influenced the extent to which children imitated a partner's language use. In two experiments, 7- to 12-year-old children either experienced ostracism or did…

There can be significant diversity in the language experience of minority language children, and in the levels of proficiency reached. The declining numbers of children now exposed to Irish include those from homes where only/mainly Irish is spoken, those with only one Irish-speaking parent, and children from homes where one/both parent(s) speak…

Early trilingual development is an excellent testing ground for input reduction effects on acquisition outcomes. This article reports a study investigating input-outcome relations in a child Leo in Hong Kong, who was addressed to in Mandarin, Cantonese and later also in English by caretakers through 'one caretaker-one language' and 'one day-one…

Purpose: Language is a multidimensional construct from prior to the beginning of formal schooling to near the end of elementary school. The primary goals of this study were to identify the dimensionality of language and to determine whether this dimensionality was consistent in children with typical language development from preschool through 5th…

Scholars debate whether musical and linguistic abilities are associated or independent. In the present study, we examined whether musical rhythm skills predict receptive grammar proficiency in childhood. In Experiment 1, 7- to 17-year-old children (N = 68) were tested on their grammar and rhythm abilities. In the grammar-comprehension task,…

In this study, monolingual (English) and bilingual (English/Spanish, English/Urdu) five- and six-year-old children completed a grammaticality judgment test in order to assess their awareness of the grammaticality of two types of syntactic constructions in English: word order and gender representation. All children were better at detecting…

Children with Developmental Language Disorder are likely to experience difficulties with morphosyntax, especially regular past tense marking. Few studies have evaluated the effectiveness of intervention to improve morphosyntax in young school-aged children with DLD. This study investigated the efficacy of combined explicit and implicit…

This study investigates relationships between acquisition of exhaustivity in single and multiple "wh"-questions, mastery of semantic and pragmatic aspects of quantifier comprehension, and general skills in receptive grammar. The participants of the study were 25 Polish monolingual typically developing children aged 4;02-6;02, who were…

The current study investigated the distinction of L2 (second language) English article choice sensitivity in fifty-three L1-Korean L2-English learners in semantic contexts. In the context of English as a foreign language, the participants were divided into two groups based on grammatical ability as determined by their performance on a cloze test.…
