TLDR
Proprioceptive cues about viewing distance originating from the non-grasping limb or the inclination of the torso and/or the elbow angle of the grasping limb compensated for the loss of visual distance cues to enable a complete restoration of size constancy in grasping but only a modest improvement of sizeconstancy in perception.
