  2. Phi phenomenon - Wikipedia

    en.wikipedia.org/wiki/Phi_phenomenon

    Example of beta movement. Phi phenomenon has long been confused with beta movement; however, the founder of Gestalt School of Psychology, Max Wertheimer, has distinguished the difference between them in 1912. While Phi phenomenon and Beta movement can be considered in the same category in a broader sense, they are quite distinct indeed.

  3. Illusory motion - Wikipedia

    en.wikipedia.org/wiki/Illusory_motion

    Billboards and other electronic signs use apparent motion to simulate moving text by flashing lights on and off as if the text is moving.. The term illusory motion, or motion illusion or apparent motion, refers to any optical illusion in which a static image appears to be moving due to the cognitive effects of interacting color contrasts, object shapes, and position. [1]

  4. Korte's third law of apparent motion - Wikipedia

    en.wikipedia.org/wiki/Korte's_third_law_of...

    The third law, particularly, describes how the increase in distance between two stimuli narrows the range of interstimulus intervals (ISI), which produce the apparent motion. [4] It holds that there is a requirement for the proportional decrease in the frequency in which two stimulators are activated in alternation with the increase in ISI to ...

  5. Mathematical psychology - Wikipedia

    en.wikipedia.org/wiki/Mathematical_psychology

    Mathematical psychology is an approach to psychological research that is based on mathematical modeling of perceptual, thought, cognitive and motor processes, and on the establishment of law-like rules that relate quantifiable stimulus characteristics with quantifiable behavior (in practice often constituted by task performance).

  6. Apparent motion - Wikipedia

    en.wikipedia.org/wiki/Apparent_motion

    Beta movement, an illusion of movement where two or more still images are combined by the brain into surmised motion; Illusory motion, the appearance of movement in a static image; Phi phenomenon, an illusion of movement created when two or more adjacent lights blink on and off in succession

  7. Beta movement - Wikipedia

    en.wikipedia.org/wiki/Beta_movement

    Example of the beta movement effect. The term beta movement is used for the optical illusion of apparent motion in which the very short projection of one figure and a subsequent very short projection of a more or less similar figure in a different location are experienced as one figure moving.

  8. Piaget's theory of cognitive development - Wikipedia

    en.wikipedia.org/wiki/Piaget's_theory_of...

    For example, even young infants appear to be sensitive to some predictable regularities in the movement and interactions of objects (for example, an object cannot pass through another object), or in human behavior (for example, a hand repeatedly reaching for an object has that object, not just a particular path of motion), as it becomes the ...

  9. Autokinetic effect - Wikipedia

    en.wikipedia.org/wiki/Autokinetic_effect

    It was first recorded in 1799 by Alexander von Humboldt who observed illusory movement of a star in a dark sky, although he believed the movement was real. [2] It is presumed to occur because motion perception is always relative to some reference point, and in darkness or in a featureless environment there is no reference point, so the position ...
