Psychophysical judgments show a response bias called regression toward the mean. This study suggests this bias in memory quantification arises from cognitive adaptation, not compressed memory.

Area of Science:

  • Cognitive Psychology
  • Psychophysics
  • Human Memory

Background:

  • Regression toward the mean is a common response bias in psychophysical judgments.
  • This bias involves overestimating small values and underestimating large values, also known as response contraction bias.
  • The bias is also observed in magnitude estimation tasks involving memorized quantities.

Purpose of the Study:

  • To investigate the nature of regression toward the mean in magnitude estimation of memorized quantities.
  • To determine if the bias stems from cognitive adaptation or a compressed memory representation.
  • To analyze how estimation accuracy changes with repeated judgments and varying stimulus levels.

Main Methods:

  • Participants performed magnitude estimation of alphabetic interval distances between letters.

  • Interletter distances were varied across different levels.
  • Estimation accuracy and bias were analyzed as a function of repeated trials and stimulus magnitude.
  • Main Results:

    • Underestimated and overestimated values, and the point of least error, varied with the level of judged alphabetic distances.
    • A progressively increasing tendency toward the mean was observed with repeated estimations.
    • Estimation accuracy decreased progressively as the task was repeated.

    Conclusions:

    • Regression toward the mean in memorial quantifying judgment originates from a cognitive adaptation process.
    • The bias is not due to a permanent, compressed memory representation of stimuli.
    • The adaptive significance of this judgment bias is discussed, presenting two opposing viewpoints.
