The objective of this study was to compare body size estimation based on memory versus perception, in patients with anorexia nervosa (AN) and healthy controls, adjusting for possible confounders. Seventy-one women (AN: 37, controls: 35), aged 14-29 years, were assessed with a computerized body size estimation morphing program. Information was gathered on depression, anxiety, time since last meal, weight and height. Results showed that patients overestimated their body size significantly more than controls, both in the memory and perception condition. Further, patients overestimated their body size significantly more when estimation was based on perception than memory. When controlling for anxiety, the difference between patients and controls no longer reached significance. None of the other confounders contributed significantly to the model. The results suggest that anxiety plays a role in overestimation of body size in AN. This finding might inform treatment, suggesting that more focus should be aimed at the underlying anxiety.

“…We also predicted that there would be differences depending on the orientation in which the face was seen, with more pronounced errors when viewing the face in unfamiliar views. Previous literature has tended to test almost only female participants [13,40–42] and has shown that body distortions occur more in those dissatisfied with their bodies [43–48]. Here, we compared low and high body dissatisfaction groups in both male and female participants in order to add to the literature and advance knowledge about how gender and body satisfaction contribute to size perception.…”

Perceptual body size distortions have traditionally been studied using subjective, qualitative measures that assess only one type of body representation–the conscious body image. Previous research on perceived body size has typically focused on measuring distortions of the entire body and has tended to overlook the face. Here, we present a novel psychophysical method for determining perceived body size that taps into implicit body representation. Using a two-alternative forced choice (2AFC), participants were sequentially shown two life-size images of their own face, viewed upright, upside down, or tilted 90°. In one interval, the width or length dimension was varied, while the other interval contained an undistorted image. Participants reported which image most closely matched their own face. An adaptive staircase adjusted the distorted image to hone in on the image that was equally likely to be judged as matching their perceived face as the accurate image. When viewed upright or upside down, face width was overestimated and length underestimated, whereas perception was accurate for the on-side views. These results provide the first psychophysically robust measurements of how accurately healthy participants perceive the size of their face, revealing distortions of the implicit body representation independent of the conscious body image.
