Sometime before their second birthday, many children have a period of rapid expressive vocabulary growth called the vocabulary spurt. Theories of the underlying mechanisms differ: Accumulator models emphasize the accumulation of experience with words over time to yield a spurtlike pattern, while cognitive models attribute the spurt to cognitive…

This study investigates the acquisition and maintenance of periphrastic and se-passives in second language (L2), heritage (HS), and (Spanish-dominant) native Spanish speakers (NS) by addressing: (i) How accessible are Spanish periphrastic passives (which also exist in English) and se-passives (unique to Spanish) for L2ers and HSs in production?…

Purpose: Previous investigations reveal that children with attention-deficit/hyperactivity disorder (ADHD) produce elevated rates of linguistic mazes (i.e., filled pauses, repetitions, revisions, and/or abandoned utterances) in expressive language samples (Redmond, 2004). The current study aimed to better understand maze use of children and…

This study compared pronoun use in individuals with autism to their typically developing peers via meta-analysis and systematic review of 20 selected articles to examine differences in overall pronoun usage as well as in personal, ambiguous, possessive, reflexive, and clitic pronoun usage. Summary effects indicated significant differences between…

This paper examined to what extent causal explanation speaking tasks (CESTs) are cognitively appropriate for assessing young language learners' (YLLs) L2 speaking. Ninety-six YLLs (48 from Grade 4 and 6 each) in China performed two CESTs in both L1 (Chinese) and L2 (English). They also completed receptive and productive L2 vocabulary size tests.…

We examined differences between children with autism spectrum disorder and typically developing children over an 8-month period in: (a) longitudinal associations between expressive and receptive vocabulary and (b) the extent to which caregiver utterances provided within an "optimal" engagement state mediated the pathway from early…

This cross-sectional study investigated first (L1) and second (L2) language receptive and expressive vocabulary in a sample of 542 typically developing bilingual children of immigrants (age range 6-13), coming from six different L1 backgrounds in Norway. Results demonstrated that children's L1 and L2 vocabulary skills increased with age. From a…

Research has investigated how lexical-semantic and participant factors impact word learning in young children and adults. However, limited information pertaining to expressive vocabulary development exists for school-aged bilinguals--particularly those with developmental language disorder (DLD). Cross-linguistic differences in the semantic…

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…

Person-oriented approaches can be used to identify how teachers may draw upon a combination of strategies when interacting with individual children. For nearly 1 third of children under the age of 8 who come from a household where a language other than English is spoken, it is crucial to identify patterns of teachers' use of discourse strategies…

Background: Individuals with Williams syndrome (WS) show a disharmonic linguistic profile with a clear pattern of strengths and weaknesses. Despite their sociable nature, atypical socio-communicative abilities and deficits in communication and relationship with others have been found. Aim: The aim of the present study was to investigate whether…

This report describes a project that uses existing data sets to describe the population of students with significant cognitive disabilities and known or suspected dual sensory loss. It includes students with suspected dual sensory loss because students with significant cognitive disabilities are reported to have unidentified sensory loss (Erickson…

Research has revealed that the academic performances of learners in South Africa are below the required level. The Western Cape Education Department (WCED) launched the literacy and numeracy strategy 2006-2016 in response to the low literacy and numeracy levels. In addition, the WCED introduced the Grade 1 baseline assessment in 2006, as part of…

A discussion of the types and uses of stories in second language instruction argues that the inclination to narrate is an omnipresent human phenomenon, whether attributed to nature or to culture. The story is a means of self-expression and communication that describes different forms of narrative, both literary and nonliterary. The uses and…
