Table 3.
The top row contains the category structures used in Smith and Minda (1998, Experiments 1 and 2). The bottom row contains the category structures of a simple design and the optimal design found by the DO algorithm. The number above each design is the estimated model recovery rate obtained using the 64 stimulus vectors shown in Appendix B. The numbers in parentheses are the means and standard deviations of recovery rates based on 10 independently and randomly generated replications of the set of stimulus vectors
