A model that incorporates many of the mechanisms required to describe the multiple properties of classical conditioning (from Schmajuk et al. 1996). Novelty is the sum of the absolute values of the differences between perceived and expected (through associations with other CSs) CSs and USs. The configuration refers to internal representation of combined simple CS representations. This configural representation has the highest activity when some CSs are present and others are absent. Associations refer to the connections established between the representations of CSs and USs which allows simple and configural CSs to predict other CSs and USs
