Subjective time perception is distorted; abrupt visual stimuli make time seem longer than gradual ones. Processing time for visual onsets influences how we perceive duration.

Area of Science:

  • Cognitive psychology
  • Neuroscience
  • Perception

Background:

  • Subjective time perception can be distorted.
  • The way a stimulus appears influences perceived duration.

Purpose of the Study:

  • To investigate the distortion of subjective time perception.
  • To determine how stimulus onset type affects perceived time duration.

Main Methods:

  • Comparing perceived duration of intervals with different onset types (abrupt vs. stationary array).
  • Measuring reaction times for stimulus onset and motion onset.

Main Results:

  • The duration of an abruptly presented stimulus is perceived as longer than a succeeding interval of equal duration.
  • Processing time differences for stimulus onset and motion onset correlate with perceived time expansion.

  • Initial transient visual responses act as temporal markers for time estimation.

    • Conclusions:

    • Visual onset processing significantly impacts subjective time perception.
    • Variations in processing time for different onsets systematically alter perceived duration.
