Figure 2.
(Experiment 1) Mean suppression ratios at the tests of Acquisition, Transfer of Acquisition, Extinction, and Transfer of Extinction for the targets alone (T), for the targets preceded by the feature (F→T), and for the features alone (F), separately for the X→A/A (left side) and for the Y→B/B (right side) discriminations; 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.
