Self-recognition ability in mentally retarded adolescents

J L Fryrear, T L Kodera, M J Kennedy

    The Journal of Psychology
    |May 1, 1981
    PubMed
    Summary

    Mentally retarded adolescents showed significantly lower self-recognition abilities compared to college students. This study highlights their reliance on specific visual cues for self-recognition.

    Area of Science:

    • Psychology
    • Developmental Psychology
    • Cognitive Science

    Background:

    • Self-recognition is a key developmental milestone.
    • Previous methods for assessing self-recognition have limitations in accuracy and scope.

    Purpose of the Study:

    • To measure and compare self-recognition abilities in mentally retarded adolescents and college freshmen.
    • To introduce a novel, accurate method for quantifying self-recognition thresholds.

    Main Methods:

    • Utilized an optical system and psychophysical scaling to determine recognition thresholds.
    • Assessed 30 mentally retarded adolescents and a control group of college freshmen.

    Main Results:

    • Mentally retarded adolescents exhibited significantly higher self-recognition thresholds (p = .00003) than college freshmen.
    • Male participants demonstrated superior recognition of full-face self-images compared to females (p = .0238).

    Conclusions:

    • The findings suggest that individuals with intellectual disabilities may rely more heavily on specific visual cues for self-recognition.
    • The developed optical and psychophysical method offers improved accuracy and a broader measurement range for self-recognition abilities.
