Unformatted text preview: f cars and interacting roads, rather than looking at one car. There is not one area of the brain that defines consciousness, but rather it is an emergent property of the whole system. Neuroscientists are reluctant to start from here b/c not very testable theory. Multiple Realizability: within a complex system there may be many ways to implement a system to produce a single behavior. Testable; it is related to the theory of emergence. W/i a complex system with all these parts, there are many ways to implement a particular behavior -it is just a single behavior but there are many ways to get there. You can have different areas active in different ways, but led to the same thought. Woman studied spiny lobster -- managed to map out all 300 neurons in the spiny lobster, and then mapped out how they are all activated when the spiny lobster makes a particular move. These are tens of thousands of possible routes, that can occur for a relatively small number of behaviors. What she found is that there are many different ways in which the brain implements this behaviors. What is Consciousness?! “Can a machine think?”! One of the questions that can be asked when trying to understand consciousness is "Can a machine think?" If building a sophisticated enough robot, at what point can you start to attribute thinking to these machines. The Turing Test! First, build a machine that mimics everything that a human does. Then pose the question as:! Is it a machine or is it a human?! Created a robot named Kizmit; it can response w/ facial expression and recognize tone of voice. Paper by Alec Turing. First to think about intelligent machines before computers even came along. Says you must first define "machine" and "thinking" which ends in a hopeless lope. Says that a better way to pose this question, (called the Turing test) is first build a machine that can mimic human behavior. Is it a machine or is it human? If you accept it is a human that you are interacting with, then it has consciousne...
