Suppose a one-year-old child is playing with a toy near an electrical out-let. He sticks part of the toy into the outlet. He gets shocked, becomes frightened, and begins to cry. For several days after that experience, he shows fear when his mother gives him the toy and he refuses to play with it. What are the UCS? UCR? CS? CR? Show in diagram the three conditioning stages?

Answer:
UCS: sticks part of the toy into the electrical outlet
UCR: frightened and crying
CS: toy
CR: frightened to toy

Explanation:
Classical conditioning is a form of learning whereby a conditioned stimulus becomes associated with an unrelated unconditioned stimulus, in order to produce a behavioral response known as a conditioned response.

Unconditioned stimulus (UCS) is an agent that leads to a response without training. In this example, the child won’t know that he can have electrical shock playing with toys.

Unconditioned response (UCR) is an automatic response to a UCS that’s why the child starts crying and frightened.

Conditioned stimulus (CS) is a former natural stimulus that comes to elicit a given response after pairing with a UCS. In this situation, CS is when mom gives the same toys to the baby that was the reason for electrical shock.

Conditioned response (CR) is a learned response to a CS because the baby shows fear when he saw the same toys. It is his learned behavior.
