Talk-Aloud Protocols during Conditional Discrimination Training and Equivalence Class Formation

Training structures and stimuli used in the experiment. The numbers indicate the experimenter-defined classes and the letters indicate the different class members. The letter-number combination is only for illustration purposes and not visible for the participants. The left-most rectangles show the possible sample stimuli during training of baseline relations. The dotted lines indicate that each of the samples can be presented as sample. The solid lines with arrows point to the possible comparison arrays for each training structure. The bottom of the figure indicates the different time-windows which trials were separated. Time-window 1 was defined as when the sample was at the screen, time-window 2 was when the screen was blank for 6 s, and time-window 3 was when the comparison array was presen
