Table 1.

Card sorting performances before (left side of the table) and after (right side) equivalence class formation. Rows correspond to individual participants and are separated by group. Within groups, data are separated into participants who did and did not form equivalence classes, based on emergent relations test performances. Within the pre- and post-class formation clusters, the boxes containing three numbers correspond to the classes into which participants sorted the 15 stimulus cards. Within each of these participant-defined classes the numbers correspond to the number of cards assigned to that class from the experimenter-defined Classes 1, 2, or 3. In three cases, the post class formation sorting tests were conducted but could not be analyzed due to an error in saving the information, and, thus, are listed as NOT AVAILABLE. See text for more details.
