Summary
Adaptation to optical distortion was produced by viewing, through prisms, the trajectory of a dim point light source moved by the leg in an otherwise darkened room. The results show that such a minimal prism exposure condition produces adaptive sensorimotor shifts that alter 1. eye-foot coordination, entailing the contralateral and the ipsilateral leg, as well as 2. eye-hand coordination and 3. ego-centric localization. Generalization of adaptation produced by the minimal exposure condition was equal to that produced by the more customary prism exposure procedure, although its magnitude was somewhat smaller.
