lathe26 and sipmarton are correct. This is referring to Neural Networks, as stated in a quote buried in article. A neural network is a machine learning technique that's loosely patterned after the way neurons collaborate to process information and learn.
From what it says, I think all they did was build a neural net to do text processing & recall. Then, they tinkered with some constants and observed effects analogous to what happens when equivalent constants are changed in a human brain. Nowhere does it say that the neural net was sophisticated enough to have any degree of comprehension of the text.
This work is interesting simply because it suggests that we may be able to use computer models to analyze certain psychological conditions. That's it. It really isn't telling us anything about machine intelligence. Nor did Watson, while I'm on the subject.
