Examples of convergence in the following topics:

  • Perceiving Depth, Distance, and Size

    • Depth perception relies on the convergence of both eyes upon a single object, the relative differences between the shape and size of the images on each retina, the relative size of objects in relation to each other, and other cues such as texture and constancy.
    • Convergence upon a single point is another visual cue that provides information about distance.
    • As objects move farther away into the distance, they converge into a single point.
    • The train tracks look as though they come to a single point in the distance, illustrating the concept of convergence.

  • Perceiving Motion

    • Motion is perceived when two different retinal pathways, which rely on specific features and luminance, converge together.

  • Creativity

    • Guilford (1897 - 1987) pioneered the distinction between convergent and divergent thinking as it applies to creative thinking.
    • Convergent thinking involves aiming for a single, correct solution to a problem, whereas divergent thinking involves the creative generation of multiple answers to a problem.

  • Vision: The Visual System, the Eye, and Color Vision

    • These cues range from the convergence of our eyes and accommodation of the lens to optical flow and motion.
