[Perceptual disorders in childhood]

F Affolter

    Bulletin Der Schweizerischen Akademie Der Medizinischen Wissenschaften
    |July 1, 1976
    PubMed
    Summary

    Severely language-disturbed children often have underlying sensory-motor and perceptual integration issues. Early diagnosis and therapy targeting these perceptual deficits can improve both primitive and complex performance, including language development.

    Area of Science:

    • Developmental Psychology
    • Neuroscience
    • Speech-Language Pathology

    Context:

    • Investigates the relationship between perceptual processing and language development in children.
    • Examines developmental trajectories in children with severe language disturbances.
    • Utilizes cross-sectional and longitudinal observational methods.

    Purpose:

    • To test the hypothesis that language disturbances in children are secondary to underlying perceptual dysfunctions.
    • To identify specific types of perceptual deficits associated with severe language impairments.
    • To evaluate the efficacy of perceptual stimulation therapy in improving developmental performances.

    Summary:

    • Cross-sectional data from 71 children (3-10 years) revealed sensory-motor and perceptual integration deficits alongside complex language impairments.
    • Identified subtypes of perceptual dysfunction include auditory, tactile-kinesthetic, intermodal, and serial processing issues.
    • Longitudinal therapy with 23 children showed initial gains in primitive skills, followed by improvements in complex performances like language.

    Impact:

    • Confirms that language difficulties in some children stem from primary perceptual problems.
    • Highlights the potential for early diagnosis of perceptual dysfunction in at-risk children.
    • Demonstrates that targeted therapy can positively influence developmental outcomes in children with language disorders.
