Models at different levels

• Read the introduction, Experiments 1-3, and the discussion and conclusion. Your goal should be to understand what the phenemon being modeled is, how the model works, and what the basic results are.

Kemp, C., Perfors, A., & Tenenbaum, J. B. (2007). Learning overhypotheses with hierarchical Bayesian models.. Developmental Science, 10, 307—321.

• You can skip the section on ontological kinds. Your goal should again be to understand what the model is doing and why it produces the results it does.
