[ACT-R-users] Has 'Conceptual Knowledge' been modeled?

[Professor Ron Sun]

for work on learning 'Conceptual Knowledge’ using a cognitive architecture other than ACT-R, see, for example,

Sun, R. (2013). Autonomous generation of symbolic representations through subsymbolic activities. Philosophical Psychology, 26 (6), 888-912.  (available at:  https://sites.google.com/site/drronsun/   )
