Procedure for estimating perceived–actual discrepancy and perceived–ideal discrepancy.

A representative example of a participant’s behavior during the actual-body (blue line) and ideal-body (red line) tasks according to logistic regression modeling. (A) The right blue arrow represents the perceived–actual discrepancy, defined as a probability of choosing ‘Yes’ on the actual-body task of 0.5 (X_perc). (B) The orange arrow represents the perceived–ideal discrepancy, defined as the discrepancy between a probability of choosing ‘Yes’ on the actual-body task of 0.5 (X_perc) and that on the ideal-body task (X_ideal).
