Roger Stanton Explores How the Prototype Model Accounts for Learning Performance

This article also compares prototype and exemplar models.  However, in this case a previous article showed that a prototype model actually provided a better account of learning performance in the well-known Medin & Schaefer (1978) 5/4 paradigm.  The article shows that when the models are equated in terms of flexibility, the exemplar model does provide a better account of the learning data.
