    Perception of continuous motion from discrete steps depends on the interstep interval (ISI). Interpolation decreases with longer ISIs, and is affected by modulation frequencies below 25 Hz.

    Area of Science:

    • Visual perception
    • Motion perception

    Background:

    • Discrete movements can be perceived as continuous motion through interpolation.
    • Understanding the factors influencing this perceptual interpolation is key to visual processing research.

    Purpose of the Study:

    • To quantify the extent of spatial interpolation in apparent motion.
    • To investigate how interstep interval (ISI) and modulation frequency affect this interpolation.
    • To generalize the concept of staircase stimuli for apparent motion.

    Main Methods:

    • Vernier alignment technique to measure spatial interpolation.
    • Systematic variation of interstep intervals (ISIs) for discrete motion stimuli.
    • Application of analog-filtered and digitally filtered staircase stimuli with varying modulation frequencies and amplitudes.

    Main Results:

    • The extent of spatial interpolation decreased as the interstep interval (ISI) was lengthened.
    • Perceptual interpolation was affected by periodic modulations of the moving target only at frequencies below approximately 25 Hz.
    • The spatial amplitude of the modulation also influenced the degree of interpolation.

    Conclusions:

    • Visual interpolation of discrete motion is dependent on temporal factors (ISI) and modulation frequency.
    • The findings extend the understanding of apparent motion stimuli and their perceptual consequences.
    • Modulation frequencies above 25 Hz do not significantly impact the interpolation of discrete motion into continuous apparent motion.
