  4. la nature des sensations • sentir des choses différentes • dans une modalité sensorielle • dans différentes modalités • sentir plutôt que rien sentir Master ENS 2004 - O’Regan

  5. Le problème de la conscience phénoménale Sensations Actions Sensory inputs Brain mechanisms Master ENS 2004 - O’Regan

  7. Sentir = exercer une habilité sensorimotrice Master ENS 2004 - O’Regan

  8. vision classique nouvelle vision le cerveau génère les sensations le cerveau génère savoir et actions Master ENS 2004 - O’Regan

  9. la nature des sensations • sentir des choses différentes • dans une modalité sensorielle • dans différentes modalités • sentir plutôt que rien sentir Master ENS 2004 - O’Regan

  10. Sensorimotor Contingencies(D. M. MacKay, 1956) sensory input = f ( action ) Master ENS 2004 - O’Regan

  11. Feeling Softness knowing that sensorimotor contingencies typical of softness are currently being obeyed. Master ENS 2004 - O’Regan

  12. Seeing Red knowing that sensorimotor contingencies typical of red are currently being obeyed. Master ENS 2004 - O’Regan

  25. Previous efforts • Kohler 1951 + • Mc Collough 1965 - • Harrington 1965 - • Leppman & Wieland, 1966 + Master ENS 2004 - O’Regan

  26. Forced choice more yellow-ish more blue-ish Master ENS 2004 - O’Regan

  27. Judging white after removing glasses % responses “blue” color Master ENS 2004 - O’Regan

  28. la nature des sensations • sentir des choses différentes • dans une modalité sensorielle • dans différentes modalités • sentir plutôt que rien sentir Master ENS 2004 - O’Regan

  29. big change expanding flow shifting flow nothing big change no change increasing amplitude asynchrony big change nothing Intermodal differences SEEING HEARING blink: move forward: turn sideways: cover ears: cover eyes: Master ENS 2004 - O’Regan

  30. Tactile Visual Sensory Substitution Bach y Rita (1972; 1984) Master ENS 2004 - O’Regan

  31. testing P. Meijer’s “The vOICe” (M. Auvray) Master ENS 2004 - O’Regan

  32. Audio-Tactile SubstitutionAline Bompas, Kevin O’Regan right microphone left microphone isolating head phones Vibrator on right leg Vibrator on left leg Master ENS 2004 - O’Regan

  33. Master ENS 2004 - O’Regan

  34. Botvinick & Cohen, 1998 Master ENS 2004 - O’Regan

  35. Seeing Straightness knowing that sensorimotor contingencies typical of straightness are currently being obeyed. Master ENS 2004 - O’Regan

  36. Master ENS 2004 - O’Regan

  37. Cortex Retina Visual field Master ENS 2004 - O’Regan

  38. Master ENS 2004 - O’Regan

  40. Master ENS 2004 - O’Regan

  41. What is a sensorimotor law? S = f(M) INTRINSIC way of describing relation which is independent of the code (Differential geometry, Lie Groups) Master ENS 2004 - O’Regan

  42. Philipona, O ’Regan & Nadal, Neural Computation 2003 Master ENS 2004 - O’Regan

  43. Philipona, O ’Regan & Nadal, Neural Computation 2003 Master ENS 2004 - O’Regan

  44. la nature des sensations • sentir des choses différentes • dans une modalité sensorielle • dans différentes modalités • sentir plutôt que rien sentir Master ENS 2004 - O’Regan

  45. Why is sensory experience different from other mental phenomena? Corporality/Bodiliness • tight link to body motions Alerting capacity/Grabbiness • transients incontrovertibly grab attention Master ENS 2004 - O’Regan

  46. Corporality/Bodiliness if voluntary motions systematically affect input e.g. visual, auditory, etc. also: proprioception not: autonomic sensory pathways Master ENS 2004 - O’Regan

  47. Alerting Capacity/Grabbiness capacity to peremptorily interfere with cognitive processing (can cause exogenous attentional capture) e.g. visual, auditory pathways, etc. not: vestibular, proprioceptive, autonomic sensory pathways Master ENS 2004 - O’Regan

  48. Remembering Master ENS 2004 - O’Regan

  49. Seeing Master ENS 2004 - O’Regan

  50. "raw feel" Master ENS 2004 - O’Regan
