(Experiment 1) Mean suppression ratios at the tests of Extinction and Transfer of Extinction for the targets alone (T) and for the targets preceded by the feature (F→T), aggregated across the X→B/B and the Y→A/A pairs; the top half of the figure depicts the results of the aaa group, the bottom half the results of the aba group. Lower values represent stronger conditioned responding. Brackets represent standard errors of the means.
