    Summary

    This study introduces new tests for timing mental scanning without eye movement. Results show a left-to-right scanning tendency in individuals reading left-to-right, even without eye movement, suggesting measurable central brain processing.

    Area of Science:

    • Cognitive Neuroscience
    • Psycholinguistics

    Background:

    • Understanding the timing and sequencing of cognitive processes is crucial for mapping brain function.
    • Investigating mental scanning provides insights into information processing pathways.

    Purpose of the Study:

    • To introduce novel testing techniques for measuring short-range mental scanning.
    • To investigate the influence of reading direction on non-visual scanning behavior.
    • To explore the possibility of measuring central brain processing timing.

    Main Methods:

    • Development of computer-based tests utilizing blocking stimuli.
    • Stimuli designed to target central rather than peripheral cognitive processes.
    • Assessment of mental scanning direction in individuals with varying language backgrounds.

    Main Results:

    • Individuals whose first language is read left-to-right exhibit a left-to-right scanning tendency.
    • This tendency persists even when eye movement is not possible due to time constraints.
    • Blocking stimuli effectively target central cognitive processes.

    Conclusions:

    • The developed techniques allow for the timing of mental scanning independent of eye movements.
    • Reading directionality influences cognitive scanning patterns.
    • Central brain processing timing and sequencing can be measured using these methods.
