Slade and Russel (1973)
Lights on a string measurements face, chest, waist and hips, lights on a string. Overestimate actual body size. Exp 2: estimate model -overestimate both but more for self. Height unaffected.
1 of 14
Gardner and Brown (2014)
meta-analysis AN patients - overestimate own body size but not related to perceptual abilities. Do not overestimate inanimate objects.

Tovee et al. (2003)
More sophisticated method - actaul picture of pp use drag bar to estimate veridical shape. All overestimate but greater for BN and AN.

Cornelissen et al. (2013)
Same chort 10yrs later - BMI into account. ED not have misinterpretations of body effect you find when very slim, larger BMI underestimate. Body forced choice task unrelated to BMI but ED attidunal q
4 of 14
Keizer et al. (2011)
Tactile size estimation, callipers forearm and abdomen. Overestimate but no difference between forearm and abdomen. Enlarged body shema and body percept as well as tactile form

Spitoni et al. (2015)
overestimate tactile distance only on horizontal axis.

Eshkevari et al. (2012)
RHI ED - strong experience of illusion for synch and asynch. Unstable representation of body.

Eshkevari et al. (2014)
dominance of visual info from other bodily senses, sensory training inc contribution of internal somatosensory info, increase interoceptive and proprioceptive awareness = less malleabe more acc body rep

Preston and Ehrsson (2014)
Mannequin 15% wider/15% slimmer, body satisfaction and body perception judgements, after slimmer illusion increased satisfaction rating and slimmer estimate. ED vulnurability correlated with inc satisfaction wider body percpet

Preston and Ehrsson (2016)
3D recordings obese/slim in scanner, multisensory brain areas, decreased satisfaction obese correlate inc AIC (Kaye et al. 2013 ED), ED vulnurability ACC, ED vulnurability related connectivity PMC/IPC and AIC/ACC owning obese

Riva (2011)
Allocentric Lock Hypothesis - ED locked onto an allocentric negative disembodied memory of body not updated even after demanding diet/sig weight loss

De Vignemount (2016)
Body representation - internal cognitive structure tracks state of body, can misinterpret and become decoupled from it
12 of 14
Guardia et al. (2012)
AN - Oversized body schema, turn shoulders when going through apertures at higher critical point than controls. Keizer et al. (2013) affect action as well as perception.

Boehm et al. (2014)
Low Perceptual Body Image Distortion (BID) and high early weight gain predictive of long term treatment outcome.
