This study introduces a computer program to measure body size distortion and dissatisfaction using psychophysical methods. It quantifies perceived and ideal body size, aiding in understanding body image perception.

Area of Science:

  • Psychology
  • Computer Science
  • Human-Computer Interaction

Background:

  • Body image perception is crucial in psychological well-being.
  • Quantifying body size distortion and dissatisfaction is challenging.
  • Existing methods may lack precision in measuring subjective body size perception.

Purpose of the Study:

  • To introduce a novel computer program for measuring body size distortion and body dissatisfaction.
  • To provide a tool for researchers to quantify sensory and nonsensory components of body size judgments.
  • To assess body dissatisfaction by measuring the discrepancy between perceived and ideal body size.

Main Methods:

  • Developed a Visual Basic program for Windows systems.
  • Implemented three psychophysical methods: method of adjustment, staircase method, and adaptive probit estimation.

  • Participants manipulated digital images to match perceived or ideal body size, or judged distortion levels.

    • Main Results:

    • The program determines the point of subjective equality (PSE) and difference limen (DL).
    • DL quantifies the detectable body size distortion threshold.
    • PSE reflects the individual's subjective body size judgment.

    Conclusions:

    • The developed program offers a precise method for assessing body size perception and dissatisfaction.
    • The PSE and DL values provide insights into sensory and cognitive factors influencing body image.
    • This tool can advance research in body image and related psychological conditions.
