This study introduces a new method to measure visual motion perception during eye movements. The developed measure K quantifies how accurately we perceive motion direction when our eyes are moving.

Area of Science:

  • Visual neuroscience
  • Perception psychology

Background:

  • Perceptual constancy of visual motion relates physical motion to perceived motion.
  • Studying this requires assessing physical motion, retinal image, and perception.

Purpose of the Study:

  • To describe a quantitative estimation procedure for a measure K.
  • To measure the perceptual constancy of background target motions during ocular pursuit.

Main Methods:

  • The calculation of K is based on three vectors: physical motion, retinal motion, and perceived motion.
  • Only the direction of the perceptual motion vector requires experimental determination.

Main Results:

  • A quantitative measure K was developed for perceptual constancy of motion.

  • This measure is applicable to background target motions noncollinear to eye movements.

    • Conclusions:

    • The measure K allows for quantitative comparisons across various visual motion display experiments.
    • This provides a standardized method for assessing visual motion perception during pursuit eye movements.
