In prior work, we have demonstrated that attention to the neural implementation of cognitive function is critical in creating models capable of simulating the physiological traces of those functions (e.g., Event-Related Potentials; ERPs). Here, we extend our Parallel Distributed Processing (PDP) model of ERP data elicited during the reading of single word forms to the simplest more temporally extended phenomenon: the ERP repetition effect. Simulations demonstrate that reproducing the dynamics of the ERP repetition effect can be accomplished by imposing the temporal envelope of post-synaptic potentials on individual units in the model.
