    Summary

    Imagining a moving spot in a grid reveals cognitive limits. Accuracy significantly drops when moving from a 3x3 to a 4x4 grid, suggesting a capacity limitation in spatial visualization.

    Area of Science:

    • Cognitive Psychology
    • Human Spatial Reasoning
    • Mental Imagery

    Background:

    • Understanding the limits of human spatial working memory is crucial for cognitive science.
    • Previous research suggests that the complexity of mental visualizations impacts performance.

    Purpose of the Study:

    • To investigate the accuracy of mental spatial navigation within grids of varying sizes.
    • To identify the point at which cognitive capacity limits are reached in spatial imagery tasks.

    Main Methods:

    • Participants mentally tracked a spot's movement (Up, Down, Left, Right) in grids from 3x3 to 8x8.
    • Accuracy was measured by the participant's ability to identify the final spot position.
    • The effect of matrix structuring strategies on performance was also assessed.

    Main Results:

    • A significant decrease in accuracy was observed when transitioning from 3x3 to 4x4 grids.
    • Structuring matrices improved performance across most grid sizes, except for the 3x3.
    • Visual angle variations had minimal impact on accuracy.

    Conclusions:

    • A cognitive capacity limitation in the visual imagery system is likely exceeded between 3x3 and 4x4 grids.
    • Spatial structuring strategies can enhance mental visualization performance.
    • These findings offer insights into the nature and limitations of human mental imagery.
