- Allen Newell (father of AI?) noted that humans behave at
several different levels.
- These levels can be broken down into time bands.
- He does it by orders of magnitude with neurons firing
once every 10ms, psychological behaviour around 1s, and
social behaviour on the order of 1000s of seconds and above.
- He then went on to build a Cognitive Architecture based
on rules (Soar).
- This (and Anderson's ACT) has been successful in doing
a range of tasks and emulating human psychological behavior.
- Unfortunately, it ignores the lower neural levels of
- In particular, this means that Soar can't really learn new
symbols. It can't solve the symbol grounding task.
- Though it can learn in domains it already knows,
- it can't learn new domains.
- Consequently, it is difficult to have a domain general
