Part I

Create an example of classical conditioning. Diagram your example, using the terms NS, UCS, UCR, CS, and CR.

Bell Food Salivate

NS→ UCS→ UCR

NS is paired with UCS, becomes CS

Bell Salivate

CS→ CR

How could you strengthen the conditioning? How could you weaken it?

Increase

1. Have more of pairings of the NS (bell) with UCS (food)

2. Increase the size or taste of the UCS (food) to increase its saliency

3. Contiguity- Implement UCS (food) immediately after NS (bell)

Decrease

1. Extinction- Stop implementing UCS (food) after CS (bell)

2. Exhaustion- Have bell (CS) ring all the time

3. Counter Conditioning- It would be difficult to implement this technique with this example. Instead:

Rabbits Bite Fear

NS→ UCS→ UCR

Rabbits Fear

CS→ CR

Counter conditioning could be implemented in this example by introducing a new CS, ice cream, which produces a response (pleasure), that isn’t compatible with the old CR (fear). The old CS (rabbits) is then exposed, but doesn’t produce the old CR.

Create an example of classical conditioning pertains to instruction. Diagram your example, using the terms NS, UCS, UCR, CS, and CR.

Test Failing Stress

NS→ UCS→ CS

Test Stress

CS→ CR
