Set of personalized 3D bodies (avatars) with own shape and own photo-realistic texture.
Note, the avatars in the experiment were always shown in front view.

Top: Percent deviation of the estimated own body size (Experiment 1, left) and estimated memorized body size (Experiment 2a, right) from actual BMI (in %-BMI units) as a function of participants’ BMI in the 1AFC task. The lines represent regression lines. Bottom: Beta values (slope steepness of the yes-answer distribution) for presented bodies smaller (left side of the peak; triangles, solid line) and bigger (right side of the peak; circles, dotted line) than estimated own body size (Experiment 1, left) and estimated memorized body size (Experiment 2a, right) as a function of participants’ BMI in the 1AFC task. Higher beta values indicate greater sensitivity to %-BMI changes. The lines indicate the regression lines.

Left: BMI deviation [in %] of the estimated own body size (squares, solid line) and adjusted ideal body size (triangles, dotted line) as a function of participants’ BMI in the MoA task of Experiment 1. Right: BMI deviation [in %] of the estimated memorized body size (squares, solid line) and adjusted most attractive body size (triangles, dotted line) as a function of participants’ BMI in the MoA task of Experiment 2a. The lines represent regression lines.

Similarity ratings as assessed by the post-questionnaire for Experiment 1 (own body shape, own texture), Experiment 2a (own body shape, other texture, exposure phase) for all rating categories (appearance, arms, face, figure, legs, overall impression, and torso) for participants that completed all three experiments (n = 53).
Error bars represent standard deviation from the mean.

Top Left: Percent deviation of the estimated ‘correct’ (memorized own) body size (peak of the psychometric function) from the actual BMI (in %-BMI units) as a function of participants’ BMI in the 1AFC task. The line represents a regression line. Top Right: Beta values (slope steepness) for presented bodies smaller (left side of the peak; triangles) and bigger (right side of the peak; circles) than estimated ‘correct’ (memorized) body size as a function of participants’ BMI in the 1AFC task. Higher beta values indicate greater sensitivity to %-BMI changes. The lines indicate the regression lines of beta values on the left side (solid line) and on the right side (dotted line). Bottom Left: BMI deviation [in %] of the estimated ‘correct’ (memorized) (squares, solid line) and most attractive body size (triangles, dotted line) as a function of participants’ BMI in the MoA task of Experiment 2b. The lines represent regression lines.
