p548fig15.16 Homologous recognition learning and reinforcement learning macrocicuits enable adaptively timed conditioning in the reinforcement learning circuit to increase inhibition of the orienting system at times when a mismatch in the recognition system would have reduced inhibition of it.<BR>||  Homolog between ART and CogEM model, complementary systems.  [Recognition, Reinforcement] learning vs [Attentional, Orienting] system.  Reinforcement: timing, drive representation.
