Psychological Validity as an Issue in Cognitive Architectures

This issue is an attempt to address the question: Does the architecture make any attempt to model aspects of human behavior? The answer is not always either easy or straightforward. Certainly some research in cognitive architectures is concerned with modeling the methods by which human solve problems. An example of this is the Teton architecture. Another approach is to try to develop architectures which behave intelligently without regard to the psychological plausibility of the method by which the behavior is achieved. Still yet another approach is to claim that intelligence can not be achieved without modeling the architecture of the brain first, and then determining the methods which will produce the desired behavior.

The Einstellung Effect is an example of piece of human data some cognitive architects point to to claim some validity of their own architecture. It is the observation that once people find a solution to a problem, they tend to stick with it, even if a better method is available.

The Power Law of Learning is another example. With more practice at a task, people seem to always be getting faster. However, the rate of learning decreases the more practice one has.
