A major difference between attentional models and the Rescorla-Wagner model is described by which of the following choices?
A)In attentional models, US surprisingness has only a proactive influence on conditioning.
B)In the Rescorla-Wagner model, US surprisingness has only a proactive influence on conditioning.
C)Attentional models are US-reduction theories.
D)The Rescorla-Wagner model cannot predict blocking on the first trial of Phase 2 of the blocking experiment.

Question

Quizplus · Accepted Answer

Attentional models propose that the attentional resources allocated to a stimulus determine its associability and influence the strength of the conditioned response. Therefore, US surprisingness has only a proactive influence on conditioning in attentional models. In contrast, the Rescorla-Wagner model considers the difference between the expected and actual US value as the error signal that drives learning. Thus, US surprisingness has a retroactive influence on conditioning in the Rescorla-Wagner model. However, it is important to note that both attentional models and the Rescorla-Wagner model can account for blocking on the first trial of Phase 2 of the blocking experiment.
