Results from summation test stimuli presented again during inference test.
Presented A+/AX−/C+/DE-, tested CX, CE, for both outcome 1 and 2. Left panel: difference scores, calculated as the difference between O1 and O2 ratings for B1X1 and B1C1, and the difference between O2 and O1 ratings for B2X2 and B2C2. Right panel: outcome-specific scores, using the rating for O1 only for B1X1 and B1C1, and the rating for O2 only for B2X2 and B2C2. Error bars represent the standard error of the mean difference between test and control.
