FIGURE 6.
Retardation test in Experiment 3. PreX-X differences (±SEM), averaged for the 10 X+ presentations per session in retardation, are displayed. The black line represents the group that was trained with five A+, 11 AX−, three F−, nine F+, and two X− presentations per session in conditioning. The gray line represents the group that was trained with eight A+, five A+, 11 BX−, three F−, nine F+, and two X− presentations per session. In the retardation test, both groups received 10 X+ presentations per session.
