Distortions of body representations are not the exception but the rule. In his author- itative review, Longo [1] describes how there is a general tendency to overestimate the body width relative to the body length. For example, the perceptual representation of the hand features shortened fingers and a widened dorsum in a number of tasks and modalities (e.g., [1,2]). This raises an interesting paradox. Effective motor control requires accurate information about the structure, dimension, and position of the hand. How can highly distorted represen- tations of the hand be compatible with skilled manual action [1,3]?
