[ACT-R-users] computational basis of act-r

[Robert L. West]

by way of clarifying the distinction between symbolic systems, dynamic
systems, neural nets, and ACT-R, West & Lebiere (2001) presents a discussion
of this issue and a dynamic systems model of a symbolic system constructed
using neural networks. Lebiere & West (1999) presents an ACT-R model that
produces the same dynamic properties as the neural network model. For more
general discussions on this, Bechtel and Clark are excellent.
