Brain creates experience

Explanatory gap!

Sensation = exercising a skill

No more explanatory gap!

sensation
Sensation
  • Accessing knowledge that you are currently exercising a certain sensorimotor skill.
  • Quality of sensation: laws of sensorimotor contingency
sensorimotor contingencies d m mackay 1956
Sensorimotor Contingencies(D. M. MacKay, 1956)

The laws governing

how what you do affects sensory input

seeing red
Seeing Red

knowing that sensorimotor contingencies typical of red are currently being obeyed.

biological reflection properties
“Biological” reflection properties
  • for a biological organism
    • reflection properties are constraints over sensory inputs
    • set of reflection properties is finite dimensional

finite number of singular reflection properties

Seeing is making an internal representation

Seeing is visually manipulating

the impression of seeing everything
The impression of seeing “everything”

richness not in the head

have algorithms to access information

you see what you visually manipulate

world as outside memory

(O’Regan, 1992; cf. also Minsky, 1988; R. Brooks, 1991)

sensory substitution
Sensory Substitution
  • “rewired” ferrets (Sharma, Angelucci & Sur, 2000; Melchner, Pallas & Sur, 2000)
  • Phantom limbs
  • TVSS (Bach y Rita, 1972, 1984)
  • substitution of vision through sound
  • embodiment in virtual reality
    • Murray & Sixsmith (1999); Heim (1995)

Space from sensorimotor contingenciesPhilipona, O'Regan & Nadal, Neural Computation, 2003.Philipona, O'Regan, Nadal & Coenen, NIPS, 2003.

Each light can freely move in 3D space

Each eye is constitued of a retina made of randomly distributed omnidirectional photosensitive cells, and a diaphragm

Each joint can freely rotate (rotule)

Each segment can stretch (piston)
