Fig 2.

Percentage of baseline, symmetry, 1-, 2-, 3-, and 4-node probe trials in each block that evoked class-indicative comparison selections during Emergent Relations Test 1. The panels in the left column are for the subjects who formed equivalence classes. The panels on the right hand side of the figure are for subjects who did not form equivalence classes. For a given subject, each set of bars is for one presentation of the test block. Within each block, the bars from left to right indicate the performances occasioned by the baseline, symmetry, 1-, 2-, 3-, and 4-node probes, respectively.
