CronoDragoon,
You can do that today, by inducing that change indirectly, psychologically instead of neurologically. Top Down, instead of Bottom Up.
StarcloudSWG,
I'm not sure that description is correct. The semi-randomness may happen on the micro level - sort of a minute trial and error process, but on the macro level there is order. It goes along with the Psychological development of the child.
So, to apply it to Geth or any AI, really, the process can happen not in random. Also, Neural Networks (software) have lots of randomness in them. Again, it's still very far from a brain, but we are getting there.
For example, I'm developing a... solution - I can't specify for what - that uses Semantic-like Reasoning to learn/study a User on his myriad of operations on a PC (work, play, operations of applications and HID). The idea is that through the combination of Semantic links between the various objects in the knowledge base, and statistic accumulation (learning normas and clusters) and the ability to expand upon those links in a directed way (instead of random walk), based on those statistics, we can design a semi Cognitive agent that can identify if the user working on the computer currently is the one that's supposed to.
This can easily expand to any area of reasoning and even reaction to anxiety and fear, for example.
To further explain, I'll answer rekn2's question,
It's not about Chemical effects working on a Digital Brain.
Take for example the induction or inception of Fear and/or Infatuation.
There's no pheromone at work for Fear and doesn't need to be for Infatuation.
It's an internal process, whereby events perceived by the various sensors (Sight, Sound in this case) induce, in parallel to cognitive processes/explanations, elevated levels of neural transmitions - again, within the body, within the brain. Nothing that comes from outside directly (chemically).
This is basically how the Anxiety state of emotion that is Fear comes to pass.
This internal state, moving forward, can induce, for example, infatuation, if you see a girl (for a guy) near or along with whatever is causing your Fear.
That's why Horror movies are so great for a sex life
But, again, these examples are purely internal.
It's just the chemicals in this case are the means of conveyance of the neural signals, whereas for an AI these means are virtual, software, code structures in the memory.
