    Area of Science:

    • Cognitive Neuroscience
    • Science Education
    • Neuroscience

    Background:

    • Scientific problem solving is a key area in cognitive neuroscience and science education.
    • Limited understanding exists regarding the brain dynamics underlying scientific problem-solving processes.

    Purpose of the Study:

    • To investigate if the Brain Symmetry Index (BSI) derived from electroencephalography (EEG) can serve as an index for neural information during scientific problem-solving.
    • To explore the neural mechanisms involved in solving physics problems of varying complexity.

    Main Methods:

    • Utilized electroencephalography (EEG) to record brain activity.
    • Employed two levels of complexity in physics problems to assess problem-solving.
    • Analyzed the Brain Symmetry Index (BSI) across different frequency bands (theta, alpha, beta) and brain regions (prefrontal, occipital).

    Main Results:

    • A greater BSI was observed in the prefrontal theta and beta bands during more difficult problem-solving tasks.
    • A smaller BSI was found in the occipital alpha band when tackling challenging problems.
    • No significant correlation was found between BSI and subjective self-effort evaluations.

    Conclusions:

    • The Brain Symmetry Index (BSI) shows potential as a valid EEG-based index to reflect underlying brain functional characteristics during scientific problem-solving.
    • EEG analysis, particularly BSI, can offer insights into the neural processes differentiating problem-solving complexity.
