Dogs Are Trained with a Red-Light S+ and a Yellow-Light

Multiple Choice

Dogs are trained with a red-light S+ and a yellow-light S- in context 1.Then, in context 2, the same dogs receive training with a yellow-light S+ and a red-light S-.Assuming they receive the same number of reinforcers in each context during training, what will be the role of the contexts in the subsequent test trials in each context?

A) The contexts will be associated with different S+/S- contingencies.
B) The contexts will not appear to control behavior because the reinforcers delivered in each context were the same.
C) Context 1 will cause a peak shift of the performance in context 2 because excitatory training occurred there first.
D) Context 2 will cause a peak shift of the performance in context 1 because of recency effects.
