From: The relationship between orthorexia nervosa symptomatology and body image attitudes and distortion
Reverse correlation method to measure body image dissatisfaction and distortion. (a) Example of the steps involved in the creation of a pair of stimuli in the image-construction phase using a participant’s photograph. (b) Examples of stimuli generated through the reverse correlation technique in the image-construction phase for this participant. Patches of visual noise added to her photograph randomly modulates her body’s appearance. (c) Example of trials in the first task (perceived body image). The two stimuli created on a given trial were presented side-by-side to the participant. The images selected by the participant in each of the 500 trials were averaged to produce her perceived body image representation. (d) Example of trials in the second task (ideal body image). (e) Example of comparisons by two new groups of independent participants during phase 2 to assess body image distortion and dissatisfaction of participants tested during phase 1.
