Design of Experiment 2: Retardation Test

Condition	Phase 1	Phase 2	Phase 3	Test	Mean	SEM
Inhibitor	15 AX−	5 A+ / 5 B+	1 B+ / 1 Y+ / 1 X+	X	3.69	0.50
Control	15 AX−	5 A+ / 5 B+	1 B+ / 1 Y+ / 1 X+	Y	5.22	0.50

Note. A, B, X, and Y denote geometrical figures used as stimuli. Numbers next to pairings denote number of trials. “+” = outcome. “−“ = no outcome. Inhibitor = target inhibitor after one reinforced trial. Control = cue with no inhibitory history after one reinforced trial. Mean = mean rating of all participants for each cue (X = Inhibitor; Y = Control) on a scale of 1 to 9. SEM = standard error of the mean.
