  • Specific Language Impairment
    Oxford Research Encyclopedia of Psychology, 2017
    Co-Authors: Laurence B. Leonard
    Abstract:

    Children with Specific Language Impairment (SLI) have a significant deficit in their ability to acquire Language that cannot be attributed to intellectual disability, neurological damage, hearing loss, or a diagnosis of autism. These deficits can be long-standing, and adversely affect other aspects of the affected individual’s life. There seems to be a genetic component to SLI, but the disorder is not likely to be traced to a single gene. The problem appears to be universal, but symptoms vary depending on the Language being learned. Current attempts to account for SLI have increased our understanding of the most salient symptoms of the disorder, but a full understanding of SLI is not yet within reach.

  • Specific Language Impairment across Languages
    Child Development Perspectives, 2014
    Co-Authors: Laurence B. Leonard
    Abstract:

    Children with Specific Language Impairment (SLI) have a significant and longstanding deficit in spoken Language ability that adversely affects their social and academic well-being. Studies of children with SLI in a wide variety of Languages reveal diverse symptoms, most of which seem to reflect weaknesses in grammatical computation and phonological short-term memory. The symptoms of the disorder are sensitive to the type of Language being acquired, with extraordinary weaknesses seen in those areas of Language that are relatively challenging for younger typically developing children. Although these children's deficits warrant clinical and educational attention, their weaknesses might reflect the extreme end of a Language aptitude continuum rather than a distinct, separable condition.

  • Speech disruptions in the sentence formulation of school‐age children with Specific Language Impairment
    International Journal of Language & Communication Disorders, 2009
    Co-Authors: Denise A. Finneran, Laurence B. Leonard, Carol A. Miller
    Abstract:

    Background: Many school‐age children with Specific Language Impairment produce sentences that appear to conform to the adult grammar. It may be premature to conclude from this, however, that their Language formulation ability is age appropriate.Aims: To determine whether a more subtle measure of Language use, speech disruptions during sentence formulation, might serve to distinguish children with Specific Language Impairment from their typically developing peers at an age when grammatical accuracy was high. We analysed the rate of speech disruptions in simple sentence production in school‐age children with Specific Language Impairment and typically developing age‐matched peers. We predicted that: (1) the Specific Language Impairment group would exhibit more speech disruptions than the typically developing group as a result of reduced Language proficiency even when grammatical accuracy was high; and (2) the Specific Language Impairment group would demonstrate greater reductions in disruption frequency as c...

  • The Expression of Aspect in Cantonese-Speaking Children With Specific Language Impairment
    Journal of Speech Language and Hearing Research, 2005
    Co-Authors: Paul Fletcher, Laurence B. Leonard, Stephanie F. Stokes, Anita M.-y. Wong
    Abstract:

    Previous studies of verb morphology in children with Specific Language Impairment (SLI) have been limited in the main to tense and agreement morphemes. Cantonese, which, like other Chinese Language...

  • The comprehension of wh-questions in children with Specific Language Impairment.
    Journal of Speech Language and Hearing Research, 2004
    Co-Authors: Patricia Deevy, Laurence B. Leonard
    Abstract:

    Current theories of Specific Language Impairment (SLI) in children fall into 2 general classes: those that attribute SLI to processing limitations and those that attribute the disorder to deficits ...
