5 Master ENS 2004 - ORegan Le problème de la conscience phénoménale Brain mechanisms Sensations Sensory inputs Actions

6 Master ENS 2004 - ORegan Sentir = exercer une habilité sensorimotrice

7 Master ENS 2004 - ORegan Sentir = exercer une habilité sensorimotrice

8 Master ENS 2004 - ORegan le cerveau génère savoir et actions le cerveau génère les sensations vision classique nouvelle vision

9 Master ENS 2004 - ORegan la nature des sensations sentir des choses différentes –dans une modalité sensorielle –dans différentes modalités sentir plutôt que rien sentir

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

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

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

13 Master ENS 2004 - ORegan Red is the way red things change the light (Broackes, 1992)

14 Master ENS 2004 - 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)

44 Master ENS 2004 - ORegan la nature des sensations sentir des choses différentes –dans une modalité sensorielle –dans différentes modalités sentir plutôt que rien sentir

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

47 Master ENS 2004 - 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 2004 - ORegan Remembering

49 Master ENS 2004 - ORegan Seeing

50 Master ENS 2004 - ORegan "raw feel"

52 Master ENS 2004 - 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

54 Master ENS 2004 - ORegan The experience of softness E. Myin EXERCISING A SKILL ! COGNITIVELY ENGAGING IN

55 Master ENS 2004 - 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

57 Master ENS 2004 - 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

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 2004 - 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…)
