Question

question 15
classical conditioning is most clearly biologically adaptive because it enables us to learn that the ______ predicts the
onset of the ______.
a us; ur
b us; cs
c ur; cr
d cs; us

Explanation:

In classical conditioning, the conditioned stimulus (CS) is a previously neutral stimulus that, after becoming associated with the unconditioned stimulus (US), comes to trigger a conditioned response. The biological adaptiveness lies in the ability to predict the onset of the US (which has biological significance, like food for survival) through the CS. For example, in Pavlov's experiment, the bell (CS) predicted the onset of food (US).

Answer:

D. CS; US
