4 la nature des sensations sentir des choses différentes –dans une modalité sensorielle –dans différentes modalités sentir plutôt que rien sentir

5 Master ENS ORegan Le problème de la conscience phénoménale Brain mechanisms Sensations Sensory inputs Actions

6 Master ENS ORegan Sentir = exercer une habilité sensorimotrice

7 Master ENS ORegan Sentir = exercer une habilité sensorimotrice

8 Master ENS ORegan le cerveau génère savoir et actions le cerveau génère les sensations vision classique nouvelle vision

9 Master ENS ORegan la nature des sensations sentir des choses différentes –dans une modalité sensorielle –dans différentes modalités sentir plutôt que rien sentir

10 Master ENS ORegan sensory input = f ( action ) Sensorimotor Contingencies (D. M. MacKay, 1956)

11 Master ENS ORegan Feeling Softness knowing that sensorimotor contingencies typical of softness are currently being obeyed.

12 Master ENS ORegan Seeing Red knowing that sensorimotor contingencies typical of red are currently being obeyed.

13 Master ENS ORegan Red is the way red things change the light (Broackes, 1992)

14 Master ENS ORegan Non-uniformity of color sampling

41 What is a sensorimotor law? S = f(M) INTRINSIC way of describing relation which is independent of the code (Differential geometry, Lie Groups)

42 Master ENS ORegan Philipona, O Regan & Nadal, Neural Computation 2003

43 Master ENS ORegan Philipona, O Regan & Nadal, Neural Computation 2003

44 Master ENS ORegan la nature des sensations sentir des choses différentes –dans une modalité sensorielle –dans différentes modalités sentir plutôt que rien sentir

45 Master ENS ORegan Why is sensory experience different from other mental phenomena? Corporality/Bodiliness –tight link to body motions Alerting capacity/Grabbiness –transients incontrovertibly grab attention

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

47 Master ENS ORegan 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

48 Master ENS ORegan Remembering

49 Master ENS ORegan Seeing

50 Master ENS ORegan "raw feel"

51 Master ENS ORegan "raw feel"

52 Master ENS ORegan alerting capacity vision, hearing pain INCREASING SENSORY FEEL thought, memory obsession, worry proprioception richness happiness loneliness fear love embarassment vestibular sense driving touch, smell corporality

53 Master ENS ORegan EXERCISING A SKILL ! The experience of softness E. Myin

54 Master ENS ORegan The experience of softness E. Myin EXERCISING A SKILL ! COGNITIVELY ENGAGING IN

55 Master ENS ORegan cognitively engaging in: Having an experience the exercise of a skill thinking, remembering motor skills: perceiving: different qualities Sensory Quality Phenomenality bodiliness & grabbiness bodiliness

56 Master ENS ORegan A sensorimotor account of vision and visual consciousness J.K.ORegan & A.Noë Behavioral and Brain Sciences, 5, 2001

57 Master ENS ORegan La conscience phénoménale en une phrase Avoir une sensation (perceptive) = être en train d accéder au savoir qu on exerce actuellement une habilité sensorimotrice d un type spécifique spécificités des habilités sensorimotrices perceptives: monde comme source d informations (mémoire externe) corporalité capacité d alerte

58 Master ENS ORegan Mystères de la conscience phénoménale

59 Master ENS ORegan Ressources Transparents du cours et autres infos: Articles en ligne sur la conscience: PSYCHE JCS Abstracts de conférences régulières: ASSC Tucson (Toward a Science of Consciousness)

60 Master ENS ORegan Quelques suggestions darticles 1 !! = contraire de mon approche; * = compatible mais nexpliquant pas la P-conscience très neuro: * Moshe Bar & Irving Biederman, Localizing the cortical region mediating visual awareness of object identity (awareness area) * Nancy Kanwisher, Neural events and perceptual awareness (review on NCC) !! Christof Koch (NCC) !! Gabriel Kreiman, Itzhak Fried, & Christof Koch (Single neuron awareness) Erik D. Lumer *and Geraint Rees (Awareness and rivalry) Lumer, Friston & Rees (aware percepts in rivalry) Maknik & haglund (optical images correlate with percept not with input) Sahraie, L. Weiskrantz, J.L. Barbur, et al (aware and unaware areas in blindsight) D.L. Sheinberg & N. Logothetis (aware vs unaware neurons in rivalry) !! R. Srinivasan, D.P. Russell, G.M. Edelman, & G. Tononi !! G. Tononi, R. Srinivasan, D.P. Russell, & G.M. Edelman (awareness in large numbers of synchronous neurons) !! S. Zeki, S. Aglioti, D. McKeefry, & G. Berlucchi (V1-V2 wavelength; V4 color constancy)

61 Master ENS ORegan Quelques suggestions darticles 2 plutôt psycho ou philo: * Bernard Baars (comparison of aware and aware states) ** Chalmers (phil discussion of NCC: good!) !! Churchland (misguided hope in neural hypotheses) !! Cotterill (master module) !! Crick & Koch (time for NCC!) !! Eccles (presynaptic vesicular grids of the boutons ) ? Hernegger (how brain generates sensations? Interesting?) ** Hurley & Noë (cortical dominance and deference) Rees, Kreiman & Koch (review on NCC) !! John Smythies (biochemical basis of coma) ** Ruediger Vaas, (Why neural correlates of consciousness are fine, but not enough (seems good!) * Baars (global workspace article) * Myles Bogner, Uma Ramamurthy, & Stan Franklin, Consciousness and conceptual learning in a socially situated agent (seems interesting!) !! Stanislas Dehaene, Michel Kerszberg, and Jean-Pierre Changeux !! Stevan Harnad Consciousness: An afterthought (an attempt to account for P-consc. Interesting?) !* Anthony Jack & Tim Shallice, Introspective physicalism as an approach to the science of consciousness (doesnt explain P-consc?) !!!! Steven Lehar, Gestalt isomorphism (mystical?) * Don Mathis & Michael Mozer (temporally stable computational states…) * Josh McDermott, Global workspace theory: Consciousness explained? (interesting critique of Baars) ?? George McKee, The engine of awareness: Autonomous synchronous representations (somehow time provides qualia…)
