Trial-by-trial analysis of emergent relations test performances. Matricies for 5 participants that display the frequencies of selecting each comparison (columns) in the presence of each sample (rows) stimulus in the last emergent relations test block. A maximum of three trials were presented for each relational probe. Thus, the formation of a 5-member experimenter-defined class involved the presence of 3s in each cell for a given class. The 4-STIMULI panel is a theoretical outcome. See text for more details.
