Systems entering the Human cognitive abilities must have arisen through some Cognitive Decathlon are judged, perhaps figuratively, based on evolutionary history. Finally, there is a set of implementation issues rife among Because of prior constraints on its timing, there are limits researchers in the ACT-R community.

One could ask some developmental disorders. However, classical connectionists are quite explicit that 5.
