    Summary

    Infants with motor handicaps can achieve object permanence on schedule. A nontraditional assessment showed no difference in development between manipulators and nonmanipulators, unlike traditional tests.

    Area of Science:

    • Developmental Psychology
    • Pediatric Motor Development

    Background:

    • Object permanence is a key developmental milestone in infants.
    • Motor handicaps may potentially impact cognitive development, including object permanence.
    • Understanding how motor skills influence cognitive development is crucial for early intervention.

    Purpose of the Study:

    • To investigate the effect of motor handicaps on the development of object permanence in young children.
    • To compare object permanence assessment using traditional and nontraditional methods in infants with varying motor abilities.
    • To determine if motor skills (manipulator vs. nonmanipulator) affect object permanence development.

    Main Methods:

    • Evaluated motor abilities in 12 infants (13-29 months) to classify them as manipulators or nonmanipulators.
    • Assessed object permanence using both traditional and nontraditional methods.
    • Recorded heart rate and visual tracking during nontraditional assessments.

    Main Results:

    • A significant difference was found between traditional testing results and age-appropriate object permanence levels (p < .02).
    • No significant difference was observed between nontraditional assessment results and age-appropriate levels.
    • No significant difference in object permanence development was found between infants classified as manipulators and nonmanipulators.

    Conclusions:

    • Nontraditional assessments may provide a more accurate measure of object permanence in infants with motor handicaps.
    • Motor handicaps do not appear to impede the expected developmental trajectory of object permanence when assessed appropriately.
    • Findings suggest that infants with motor impairments can achieve object permanence within typical developmental timelines.
