CLARION is able to model impressive ranges of data from human experiments.
These include modeling implicit and explicit learning, as well as manifesting
the synergy of the two under appropraite conditions.  Sun also makes numerous
comparisons between CLARION and other models in the literature, arguing for
a clear superiority for the phenomena CLARION is intended to capture. 

Sun is one of the leaders in exploring the potentialities of hybrid systems, 
part network and part symbolic manipulation, and CLARION illustrates why. 
For anyone interested in a summary of, or an introduction to, his work, these
parts of the book are recommended.

In sum, I found Sun's CLARION a strong and interesting exploration of the power
of hybrid models to capture properties of human learning and problem solving.
It is among the best and is to be highly recommended to anyone for whom
computer models in this domain are in the least relevant.

I found the attentions to broader foundational concerns---representation, 
consciousness, and sociality---to be refreshing in a book with a focus on
computational model. Again, Sun is to be strongly applauded for recognizing 
that such issues must be addressed and cannot simply be postponed.
