Purpose: This study examined vocabulary profiles in young cochlear implant (CI) recipients and in children with normal hearing (NH) matched on receptive vocabulary size to improve our understanding of young CI recipients' acquisition of word categories (e.g., common nouns or closed-class words). Method: We compared receptive and expressive…

This paper attempts to investigate the repetition of Relative Clauses (RCs) in Mandarin children with Developmental Language Disorder (DLD) (aged 4; 5 to 6; 0) and their typically developing (TD) peers. The results of a sentence repetition task indicate that Mandarin children with DLD perform significantly worse than both groups of TD children,…

Purpose: Children with poor language tend to have worse psychosocial outcomes compared to their typically developing peers. The most common explanations for such adversities focus on developmental psychological processes whereby poor language triggers psychosocial difficulties. Here, we investigate the possibility of shared biological effects by…

Purpose: The aim of this study was to investigate whether children with receptive-expressive language delay (R/ELD) and expressive-only language delay (ELD) differ in their use of gesture; to examine relationships between their use of gesture, symbolic comprehension, and language; to consider implications for assessment and for the nature of…

Hemispherectomy (disconnection or removal of an entire cerebral hemisphere) is a rare surgical procedure used for the relief of drug-resistant epilepsy in children. After hemispherectomy, contralateral hemiplegia persists whereas gross expressive and receptive language functions can be remarkably spared. Motor speech deficits have rarely been…

Background: There is a dearth of assessments of sign language development in young deaf children. This study gathered age-related scores from a sample of deaf native signing children using an adapted version of the MacArthur-Bates CDI (Fenson et al., 1994). Method: Parental reports on children's receptive and expressive signing were collected…

Fragile X syndrome (FXS) is the leading inherited cause of intellectual disability. The syndrome is caused by a single gene mutation on the X chromosome. Although individual differences are large, most individuals with FXS display weaknesses across all language and literacy domains compared with peers of the same chronological age with typical…

Purpose: Comparing children's skills across and within domains of development has become a standard in providing early intervention services. Profiling a child's strengths and challenges can help in making decisions regarding eligibility, diagnosis, and intervention. Profiling is particularly important for children who are not yet talking, due to…

This longitudinal investigation charted the course of cognitive and language development from the prelinguistic period to multiword productions in 19 typically developing toddlers and 4 toddlers who were subsequently identified as having a late onset of expressive language. Three different developmental profiles were identified, and predictors of…

Comparison of spontaneous language samples of 30 toddlers diagnosed with specific expressive language impairment (SLI) and language samples of typically developing toddlers found the SLI toddlers vocalized significantly less often, had proportionately smaller consonantal and vowel inventories, and used a more restricted and less mature array of…
