- Title
The size-weight illusion, emulation, and the cerebellum.
- Authors
Hubbard, Edward M.; Ramachandran, Vilayanur S.
- Abstract
In this commentary we discuss a predictive sensorimotor illusion, the size-weight illusion, in which the smaller of two objects of equal weight is perceived as heavier. We suggest that Grush's emulation theory can explain this illusion as a mismatch between predicted and actual sensorimotor feedback, and present preliminary data suggesting that the cerebellum may be critical for implementing the emulator.
