Cognitive development in severely mentally handicapped children shows significant deficits, especially in imitation skills. The Uzgiris-Hunt Scales revealed these challenges in pre-verbal sensorimotor intelligence compared to normative data.

Area of Science:

  • Developmental Psychology
  • Child Neurology
  • Cognitive Science

Background:

  • Cognitive development in children with severe intellectual disabilities requires detailed assessment.
  • Pre-verbal sensorimotor intelligence is a crucial early developmental domain.
  • The Uzgiris-Hunt Scales provide a framework for evaluating infant psychological development.

Purpose of the Study:

  • To assess the cognitive development patterns in severely mentally handicapped children.
  • To compare the sensorimotor intelligence of these children against established normative data.
  • To identify specific areas of cognitive deficit in this population.

Main Methods:

  • Utilized the Uzgiris-Hunt Scales of Infant Psychological Development (1975).
  • Assessed pre-verbal sensorimotor intelligence.

  • Compared performance against normative data established by Uzgiris & Hunt.

    • Main Results:

    • Severely mentally handicapped children exhibited considerable deficits in cognitive development.
    • Imitation emerged as a particularly challenging area for these children.
    • Deviations from normative developmental patterns were significant.

    Conclusions:

    • There are notable deficits in the sensorimotor cognitive development of severely mentally handicapped children.
    • Imitation skills are significantly impaired in this population.
    • Early intervention focusing on sensorimotor and imitative skills may be beneficial.
