This article reviews research on speech and language abilities in people with cri du chat syndrome (CCS). CCS is a rare genetic disorder, with an estimated incidence between 1 in 15,000 and 1 in 50,000 births, resulting from a deletion on the short arm of chromosome 5. In general, individuals have delayed speech and language development, and some…

The purpose of this study was to test the effects of playful physical contact as an establishing operation (EO) on correct academic responses for four-year-old preschool students with developmental disabilities who functioned at the pre-speaker and pre-listener levels of verbal behavior. Two males and one female served as participants who attended…

Teaching communication skills to children with autism is a primary concern because speech and/or language delay characterize autism. One method of teaching verbal communication skills to children with autism is script fading. This study examined the effects of teaching children with autism to exchange information to peers about objects and…

We compared the expressive syntax and vocabulary skills of 35 boys with fragile X syndrome and 27 younger typically developing boys who were at similar nonverbal mental levels. During a conversational speech sample, the boys with fragile X syndrome used shorter, less complex utterances and produced fewer different words than did the typically…

Autism spectrum disorders (ASDs) are diagnosed when individuals show impairments in three behavioural domains: communication, social interactions, and repetitive, restrictive behaviours and interests (RRBIs). Recent data suggest that these three sets of behaviours are genetically heterogeneous. Early language delay is strongly associated with ASD,…

Background: Research has investigated late-talking toddlers because they are at great risk of continuing to experience language-learning difficulties once they enter school and hence are candidates for early intervention. It is also important to consider this group of children with regards to the immediate characteristics which are detrimental to…

The impact of language delays and behavior problems in young children on family function was assessed using data from the 2003 National Survey of Children's Health. Over 50% of parents who reported concerns regarding their children's language skills also reported concerns regarding their children's behavior. Although parents reported increased…

This article describes caretaker interactive and communicative behaviors in various minority cultures in the context of independent/interdependent dimensions of the social world. Attention regulation, pragmatic input, and object engagement and play exemplify how caretakers from minority cultures interact with children differently than caretakers…

This study is part of the German Language Development Study's prospective longitudinal research programme on infants from birth until the age of 3 years. Thirty-four infants were retrospectively classified into two groups (normal/delayed) by their language skills at 2.5 years of age. Frequency spectrograms and melodies of about 11,000 cries from…

Parents of children with suspected Childhood Apraxia of Speech (sCAS, n = 20), Specific Language Impairment (SLI, n = 20), and typically developing speech and language skills (TD, n = 20) participated in this study, which aimed to quantify and compare reports of early vocal development. Via a questionnaire, parents reported on their child's early…

Background: Many school-age children with language impairments are enrolled in mainstream schools and receive indirect language therapy, but there have been, to the authors' knowledge, no previous controlled studies comparing the outcomes and costs of direct and indirect intervention delivered by qualified therapists and therapy assistants, and…

Proposed is a conceptual framework for analyzing aberrant or retarded language development in terms of specific process deficits in normal language acquisition. (Author/CL)

Analysis of speech samples and nonlimitated productions of polysyllabic single word utterances in eight speech delayed five- to six-year-olds revealed that syllable deletion and intervocalic consonant deletion were related to specific syllable context conditions. Increased process use in syllables of reduced stress early in a sequence was…

Background: Children with delayed speech and language development are at considerable risk for later language impairment, social and behavioural problems, and illiteracy. Early diagnosis is needed for intervention planning and prevention. However, a speech and language test for Thai children has not been available. Aims: To establish a Thai Speech…

The purpose of this study was to investigate the concurrent validity of subtests on the "Comprehensive Assessment of Spoken Language" (CASL) by comparing them with the assessment of communication and social skills on the "Vineland Adaptive Behavior Scales" ("Vineland"). The participants were 35 children and…
