Increasing the number of pairings of the US and NS (step 3) will: A. a) strengthen the connection between the CS and CR. B. b) weaken the connection between the CS andCR. C. c) weaken the CR at first, and then strengthen it. D. d) strengthen the CR at first, and then weaken it. E. e) have no effect on the CR.

A - Strengthen the connection between the CS and CR

Explanation:

In classical conditioning, it is found that behavior (CR) is affected by something that took place just before the behavior (the CS-UCS pairing).

Therefore, the operant response is usually affected by what took place after the behavior – that is by its consequences.

For example:

If Adams gets hungry whenever he perceives the aroma of his favorite food, an alarm is rung at that exact time.

In this case, the alarm (CS) is said to be the conditioned stimulus which will trigger the hunger (CR) when it is paired with the smell of your favorite food (UCS).

Therefore, increasing the number of the pairings of the US and NS strengthen the connection between CS and CR.
