Abstract
To determine stimuli with which there would be no differential generalization when used in transfer tests, 10 rats learned a successive vertical-horizontal stripe discrimination and were then tested for generaliztion with the following stimuli: 4-cell checkerboard, lattice, and eight sets of stripes ranging in slope from 10 deg to 80 deg. There was no differential generalization with the checkerboard, but there was generalization from horizontal stripes to the lattice. Interpolation from responses to stripes of 40-deg and 50-deg slopes indicated that with a slope of 42.9 deg there would be equal generalization from the horizontal and vertical standards.
