    Summary
    This summary is machine-generated.

    Pathologic left-handedness lacks empirical support and its continued use may stem from a desire to re-establish brain symmetry. This review questions the scientific validity of this concept.

    Area of Science:

    • Neuroscience
    • Psychology
    • History of Science

    Background:

    • The concept of "pathologic left-handedness" has historical roots and empirical considerations.
    • This concept has been historically linked to theories of brain lateralization and function.

    Purpose of the Study:

    • To critically review the concept of "pathologic left-handedness" from historical and empirical perspectives.
    • To evaluate the scientific evidence supporting the continued use of this concept.

    Main Methods:

    • Literature review of historical and empirical studies related to left-handedness and brain function.
    • Analysis of the theoretical underpinnings and justifications for "pathologic left-handedness".

    Main Results:

    Related Experiment Videos

  • There is a lack of adequate empirical evidence to support the continued use of the concept of "pathologic left-handedness".
  • The persistence of this concept may be driven by a desire to restore perceived brain symmetry.

    • Conclusions:

    • The concept of "pathologic left-handedness" is not adequately supported by current scientific evidence.
    • Its continued use may reflect a theoretical preference for brain symmetry rather than empirical findings.
