Abstract


We present a metacognitive classifier implemented within a hybrid architecture that combines the strengths of two existing, mature cognitive architectures: ACT-R and Leabra. The classification of a set of items into pre- viously seen and novel categories (TRAIN and TEST, respectively) is carried out in ACT-R using metacogni- tive signals supplied by Leabra. The resulting system performance is analyzed as a function of various archi- tectural parameters, and future directions of research are discussed.
