Autism spectrum disorder (ASD) and fragile X syndrome (FXS) are neurodevelopmental disorders with overlapping pragmatic language impairments. Prior work suggests pragmatic language differences may run in families. This study examined specific pragmatic difficulties (i.e., linguistic mazes and perseverations) in boys (9-18 years) with idiopathic…

Aggression in early childhood has been found to predict negative outcomes later in life, including delinquency and psychopathology. The present study explored associations between young children's language, self-regulation, and physical aggression. A community sample of 126 preschool children aged 3 to 6 years (M = 4.87 years, SD = 0.87; 59% boys)…

Purpose: The aim of this study was to investigate language growth in individuals with fragile X syndrome (FXS) from early childhood to adolescence and the influence of maternal responsivity on language growth. Method: We conducted a longitudinal analysis of language development in 55 youths (44 males, 11 females) with FXS. Data collection spanned…

Purpose: Pragmatic language difficulties have been documented as part of the FMR1 premutation phenotype, yet the interplay between these features in mothers and the language outcomes of their children with fragile X syndrome is unknown. This study aimed to determine whether pragmatic language difficulties in mothers with the "FMR1"…

This study investigated how forty-six mothers modified their talk about familiar and unfamiliar nouns and verbs when interacting with their children with Down Syndrome (DS), language impairment (LI), or typical development (TD). Children (MLUs < 2·7) were group-matched on expressive vocabulary size. Mother-child dyads were recorded playing with…

This study examined (a) the relationship between gesture and speech produced by children with specific language impairment (SLI) and typically developing (TD) children, and their mothers, during shared book-reading, and (b) the potential effectiveness of gestures accompanying maternal speech on the conversational responsiveness of children.…

Background: The literature on input addressed to children with specific language impairment (SLI) has shown contrasting results on the role that parents assume during conversational interactions. Some studies have shown that parents compensate for the child's linguistic limitations. In contrast, other studies have indicated that mothers are…

Background: Maternal responsiveness has been shown to predict child language outcomes in clinical samples of children with language delay and non-representative samples of typically developing children. An effective and timely measure of maternal responsiveness for use at the population level has not yet been established. Aims: To determine…

Purpose: The authors tested associations between (a) parent-reported temporary vs. persistent vocabulary delay and (b) parent-reported behavioral/emotional problems in a sample of 5,497 young Dutch children participating in a prospective population-based study. Method: Mothers completed the MacArthur Communicative Development…

Following a biopsychosocial model, the study investigated the role of child factors (gender, IQ), maternal factors (psychological distress, maternal education and vocabulary, maternal distress) and environmental factors (SES) in the relationship between language impairment and behaviour problems in preschool children. Participants were drawn from…

The purpose of this study was to explore Turkish mothers' verbal interaction practices and their maternal self-efficacy beliefs regarding their children with expressive language delay. Participants included 33 Turkish mothers of children with expressive language delay. Results indicated that mothers in general use child directed talk strategies or…

Three children with language impairment (ages 38 to 41 months) and their mothers participated in a study evaluating a storybook reading process for facilitating mother-child interactions. The complete reading cycle (CRC) involved: (1) attentional vocative, (2) query, (3) response, and (4) feedback. Results indicated changes in mothers' storybook…

Purpose: This qualitative study explored mothers' perceptions of their children's communication disabilities, emergent literacy development, and speech-language therapy programs. Method: Participants were 14 Mexican immigrant mothers and their children (age 17-47 months) who were receiving center-based services from an early childhood intervention…

This study explored effects of training 25 mothers to administer focused intervention to teach specific target words to their toddlers with expressive vocabulary delays. Following treatment, mothers' language input was slower, less complex, and more focused. The children used more target words, more words during play, and had larger vocabularies…

Investigates communicative intent in 31 toddlers who were slow to talk and 32 normally developing toddlers matched on SES, age, and nonverbal cognitive ability. Communicative intent was studied during free play, both with the mother and with an unfamiliar examiner. Late talkers relied more on nonword vocalization, gestures, and gesture/oral…
