Cognitive Science
Cognitive Science is today used to designate interdisciplinary work spanning:
- Computer Science / Artificiel Intelligence
- (Evolutionary) Psychology (“The Science of Psychology”)
- (Evolutionary) Anthropology
- (Evolutionary) Linguistics
- Neuroscience (yes, the FMRi scanners and all that)
- and more
Very, very exciting indeed. It seems almost certain that cognition is driven not by ingenious algorithms (like elaborate neural networks with hidden layers and all of that) - but on fuzzy kinds of approaches based on brute computational force by way of representing everything known (by the individual) in precomputed combinations in the neurons of the brain. I am working on a few pages about this - stay tuned.
