Psychological Validity of Soar
Psychological Validity of Soar
Soar was originally designed as a general engine for the universal weak methods and adopted
only the problem space
hypothesis from psychology. However, with the addition of the
learning mechanism, chunking, which
was also based on a psychological phenomena, Soar began to be used as
a cognitive model as well as a general, cognitive architecture. In
particular, Soar has been very successful at replicating results (and
thus demonstrating possible mechanisms) of the power law of practice
across different problem domains. This success lead to Newell's
proposal that Soar be considered a unified theory of cognition.
However, Soar does not cover the full range of human cognitive capability.
