    Summary

    The Cognitive Laterality Battery (CLB) offers insights into brain function. Neuropsychological tests reveal distinct patterns for visuospatial and verbal skills, aiding in cognitive profile interpretation.

    Area of Science:

    • Neuropsychology
    • Cognitive Neuroscience
    • Neurology

    Background:

    • The Cognitive Laterality Battery (CLB) is a set of neuropsychological tests.
    • Test selection was informed by research on brain-lesioned patients and healthy individuals.
    • Evidence suggests visuospatial skills are right-hemisphere dominant, while verbal and sequential skills are left-hemisphere dominant.

    Purpose of the Study:

    • To describe the Cognitive Laterality Battery (CLB).
    • To present normative data and statistical analysis for the CLB.
    • To validate the hemispheric specialization suggested by test selection through factor analysis.

    Main Methods:

    • Development of the Cognitive Laterality Battery (CLB) based on existing research.
    • Collection and analysis of normative data.
    • Application of factor analysis to confirm test dichotomies.

    Main Results:

    • Factor analyses confirmed the hypothesized dichotomy of cognitive functions.
    • Normative data and statistical findings are presented for the CLB.
    • The study supports the interpretation of CLB results as cognitive profiles.

    Conclusions:

    • The Cognitive Laterality Battery (CLB) effectively differentiates cognitive functions based on hemispheric specialization.
    • Interpreting CLB results as cognitive profiles is recommended over strict localization.
    • The study provides a validated tool for assessing cognitive laterality.
