UNLABELLED Within the human genome, genetic mapping studies have identified 10 regions of different chromosomes, known as DYX loci, in genetic linkage with dyslexia, and two, known as SLI loci, in genetic linkage with Specific Language Impairment (SLI). Further genetic studies have identified four dyslexia genes within the DYX loci: DYX1C1 on 15q, KIAA0319 and DCDC2 on 6p22, and ROBO1 on 13q. F...

Using population data, this study included parents of individuals with intellectual and developmental disabilities (n  =  220) and parents of individuals without disabilities (n  =  1,042). Parents of individuals with intellectual and developmental disabilities were further divided into those who co-resided with their adult child and those whose adult child lived elsewhere, and the 3 groups wer...

The predictive power of age and IQ at time of admission to an intensive treatment program using applied behavior analysis were examined in a 4- to 6-year follow-up of educational placement. Twenty-seven children with autistic disorder who were between the ages of 31 and 65 months and had IQs on the Stanford Binet between 35 and 109 at time of admission to the Douglass Developmental Disabilities...

PURPOSE To identify the main risk factors related to children and their parents, associated with speech and language disorders. METHODS A prospective descriptive study conducted with 170 children and their parents assisted at a school clinic in the period between March 2010 and July 2012. A protocol was developed for this study in order to identify risk factors for language and speech disorde...

Although interest in the language sciences was previously focused on newly created sentences, more recently much attention has turned to the importance of formulaic expressions in normal and disordered communication. Also referred to as formulaic expressions and made up of speech formulas, idioms, expletives, serial and memorized speech, slang, sayings, clichés, and conventional expressions, no...

Katie M. Belardi: The Nature and Nurture of Canonical Babbling in Neurodevelopmental Disorders (Under the direction of Linda R. Watson) An infant's language develops significantly during the first year of life. Language development is facilitated by an interaction between genetics and environment. Measures of vocalization development, such as canonical babbling and volubility, and the language ...
