Intelligent Control and Cognitive Systems brings you... Consciousness and Cognitive Systems Joanna J. Bryson University of Bath, United KingdomConsciousness & Cognitive Systems Can an artificial cognitive system be • conscious? Who cares? • Why care? • What is consciousness in the first place? •KC Green, Gun Show, 513Cognitive Systems & Philosophy Science fiction uses robots and aliens to • examine the human condition; the future to examine the present. AI does the same thing. • ... but, AI is also real. • Well, some of it is real. • Some of it is tangled with Sci Fi. •Roadmap for Conscious Machines 5. Executive 1. (-1) Disembodied 6. Emotional 1.

E.g. perfect self knowledge. • Consciousness is easy but combinatorics is • hard – computational explanation for biological phenomenon of unconsciousness? Bryson, Philosophy Magazine, 2007What’s Consciousness? it is nor hand, nor foot, nor arm, nor SG5-UT Robotic Arm face, nor any other part belonging to a man. Tad McGeer's passive dynamic walker Glenn Matsumura, Wired 2007 Chuck Rosenberg’s IT, 1997If this can be a hand... ...what could a mind be like?Modelling Natural Intelligence One of the best ways • to understand how something works is to build it yourself. AI is used in scientific • modelling, but also in Philosophy. Dennett: “Intuition Pumps”Consciousness as per Dennett The term conscious is itself culturally • evolved. May not refer to any one psychological • phenomenon. Like light before modern physics. •Dennett vs. The Cartesian Theatre Consciousness cannot work by infinite • recursion. Must be composed of non-conscious • elements. Nothing inside you is conscious; you are. •Multiple Drafts / The Attentional Spotlight There are many candidate parallel • processes which could be conscious. Only one is – leaves trace in episodic • memory. Not necessarily determined in order, e.g. • if driving may ‘see’ something you hit only after you hear the bump. ∴ Not really conscious all the time? •Syst em sof t ware ( 0 t h) Syst em sof t ware ( commercial processor) Periperhal Mot ion Vergence Ullman-esque Physical schema Saccades based st ereo visual rout ines based obj. recog. “Building VOR Smoot h pursuit Face pop-out s Face remembering Face recognit ion Brains Head/ body/ eye/ coord Head/ eye coord Gest ure recognit ion Facial gest ure recog.

Dennett Critics Some people really hate these ideas. • Chalmers is the main anti-Dennett • champion. Chalmers’ Hard Problem: Explaining • qualia. How do you know someone else sees • red the same way you do?The Zombie Problem (seriously) A standard problem in philosophy: how • would you tell if someone wasn’t conscious? Dennett: the zombie idea is incoherent. • (likes Brooks, embodiment theory.) • Consciousness is what it’s like to act human. • There’s nothing else. • Critics: Dennett thinks we’re all zombies •Popular Theories of Consciousness Consciousness is self-awareness. • Consciousness requires language. • Consciousness is the root of ethical • obligation / a soul. Consciousness is a special pattern of • energy (Dahaene) Consciousness is a special level of • information integration (Tononi)What People Like in Consciousness Theories We’ll never understand consciousness. • We will understand it, but not in 100 years. • I have a quantitative, scientific measure of • consciousness, but it will take 60 years until we can check if I’m right (Tononi). Only humans are conscious. •
