I need a list of classic categorization tasks (with available human/animal data) to use as a benchmark for a model.

I am interested in tasks that can be used to validate/invalidate a model of category learning

Here are some sample tasks that are used for model valuation:

  • the 5-4 task
  • Shepard, Hovland, & Jenkins, 1961
  • Medin and Schwanenflugel, 1981
  • Martin & Carmazza, 1980

any others?


  • Martin, R.C. & Caramazza, A. (1980). Classification in well-defined and ill-defined categories: Evidence for common processing strategies.. Journal of Experimental Psychology: General, 109, 320.
  • Medin, D.L. & Schwanenflugel, P.J. (1981). Linear separability in classification learning.. Journal of Experimental Psychology: Human Learning and Memory, 7, 355.
  • Shepard, R.N., Hovland, C.I. & Jenkins, H.M. (1961). Learning and memorization of classifications. Psychological Monographs: General and Applied, 75, 1-42.

See the How to Ask page for help clarifying this question. If this question can be reworded to fit the rules in the help center, please edit the question.

can you provide more detailed citations on the 'tasks like' section. Also, what kind of answer do you expect? Do you want it to point to a survey/meta-analysis, or do you want answers to start listing specific studies? If the first is the case, then clarify your question as such and add the reference-request tag. If the latter is the case, then flag your question for moderator attention so they can make it a community-wiki big-list. Finally, the more time you invest into carefully forming and communicating your question, the more likely others are to invest time in providing good answers –  Artem Kaznatcheev Jul 10 '12 at 22:23
