According to the Rescorla-Wagner model, an inhibitor will suppress responding to an excitor because
A) it nullifies the excitor's alpha.
B) lambda will be zero.
C) it blocks the excitor's association.
D) the negative associative strength of the inhibitor subtracts from the positive associative strength of the excitor.

Question

Quizplus · Accepted Answer
