Infants' search for visible objects: implications for the interpretation of early search errors.

C Sophian, L Yengo

    Journal of Experimental Child Psychology
    |October 1, 1985
    PubMed
    Summary

    Nine-month-old infants searching for hidden objects exhibit perseveration errors. However, when objects are visible, errors suggest attention lapses rather than object permanence misunderstandings, supporting information-processing theories.

    Area of Science:

    • Developmental Psychology
    • Cognitive Development
    • Infant Behavior

    Background:

    • Understanding infant object search is crucial for cognitive development research.
    • Previous studies indicate varying error patterns in object permanence tasks.

    Purpose of the Study:

    • To investigate error patterns in 9-month-old infants' object search behavior.
    • To differentiate errors in searching for hidden versus visible objects.
    • To assess the cognitive mechanisms underlying infant search errors.

    Main Methods:

    • Observing 9-month-old infants' search patterns for hidden and visible objects.
    • Comparing search locations (previous hiding place vs. control) in both conditions.
    • Analyzing error frequency and type.

    Main Results:

    • Infants showed significant perseveration when searching for hidden objects.
    • Errors were less frequent when objects were visible.
    • Visible object errors were equally distributed between previous hiding and control locations.

    Conclusions:

    • Perseveration in hidden object search suggests memory-based errors.
    • Errors with visible objects indicate attentional lapses, not a lack of object understanding.
    • Findings align with information-processing models of early cognitive search.
