This article reports on an individual differences study that investigated the role of implicit statistical learning in the acquisition of syntax in children. One hundred children ages 4 years 5 months through 6 years 11 months completed a test of implicit statistical learning, a test of explicit declarative learning, and standardized tests of…

The present study investigated the language development of 50 children with intellectual disabilities (ID) and 42 typically developing children from age 4 to 5 years, and was designed to shed more light on the respective roles of phonological working memory (WM) and nonverbal intelligence in vocabulary and syntax development. Results showed that…

This study examined whether there are processing differences between children with Down syndrome (DS; n = 22; 7 years 8 months to 13 years 10 months) and typically developing children (TD; n = 22; 6 years 6 months to 10 years 10 months), matched for receptive vocabulary. The TD children performed better on tests of nonverbal intelligence…

Our aim was to obtain versatile information on the communication and socioemotional development of implanted children in their everyday environment. We studied 18 children implanted unilaterally at the mean age of 3 years 4 months. All had normal nonverbal intelligence, but 8 (44%) had concomitant problems. Their parents filled out semistructured…

Background: The development of children's speech, language, and literacy skills is considered to build on a robust and intact speech-processing system, with normally functioning skills at all levels of input and output processing, as well as storage. There are a range of tasks available that assess input and output processing skills, however there…

Purpose: The mean length of children's utterances is a valuable estimate of their early language acquisition. The available normative data lack documentation of language and nonverbal intelligence levels of the samples. This study reports age-referenced mean length of utterance (MLU) data from children with specific language impairment (SLI) and…

Purpose: This study examined syntactic development in a large cohort of adolescents. At kindergarten, each participant had been identified as having specific language impairment (SLI), nonspecific language impairment (NLI), or typical language development (TLD). Method: The participants (n = 444) had a mean age of 13;11 (years;months; range =…

This paper presents the first ever group study of specific language impairment (SLI) in users of sign language. A group of 50 children were referred to the study by teachers and speech and language therapists. Individuals who fitted pre-determined criteria for SLI were then systematically assessed. Here, we describe in detail the performance of 13…

This study examines whether orthographic processing transfers across languages to reading when the writing systems under acquisition are sufficiently related. We conducted a study with 76 7-year-old English-first-language children in French immersion. Measures of English and French orthographic processing (orthographic choice tasks) and…

Purpose: This study examined whether late talkers identified at 24-31 months continued to have weaker language and reading skills at 17 years of age than typically developing peers. Method: Language and reading outcomes at 17 years of age were examined in 26 children identified as late talkers with normal nonverbal ability and normal receptive…

Objective: The objective of this study was to chart the developmental trajectories of high-functioning children with autism spectrum disorders (ASD) from early childhood to adolescence using the presence and absence of structural language impairment (StrLI) as a way of differentiating autism from Asperger syndrome (AS). Method: Sixty-four…

Cooperative play was investigated by a controlled pre/post-test intervention design with 28 dyads of 6-year-old students developmentally at-risk. Selection was based upon cut-off scores on a language development test and a nonverbal IQ test, and same-sex pairs were matched within classrooms. Co-variables were: socio economic status, free play time…

Books can be a rich source of learning for children and adults alike. In the present study, the contribution of shared reading and parent literacy to a variety of child outcomes was tested. Child outcomes included measures of expressive vocabulary, morphological and syntax comprehension, and narrative ability (story grammar, cohesion, and language…

The English second language development of 19 children (mean age at outset = 5 years, 4 months) from various first language backgrounds was examined every 6 months for 2 years, using spontaneous language sampling, parental questionnaires, and a standardized receptive vocabulary test. Results showed that the children's mean mental age equivalency…

Recent research has found that the acquisition of theory of mind (ToM) is delayed in children with specific language impairment (SLI). The present study used a battery of ToM and visual perspective taking (VPT) tasks to investigate whether the delayed acquisition of ToM in children with SLI is associated with delayed VPT development. Harris'…
