Suppose a one year old child is playing with atoy near an electrical outlet. he sticks part of the toy in to the outlet. he gets shocked, becomes frightened and begins to cry. for several days after that experience , he showd fear when his mother gives him the toy and he refuses to play with it. what are the ucs? ucr? cs? cr?

The correct answer is UCS

Explanation:  Unconditioned stimulus (UCS) is the one that unconditionally provokes a natural and automatic response. For example, when you smell one of your favorite foods, you may immediately feel very hungry and salivating. In this example, the smell of food is the unconditioned stimulus.

Unconditioned response (UCR) is the response that occurs naturally in reaction to the unconditioned stimulus. For example, if the smell of food is the unconditioned stimulus, the feeling of hunger in response to the smell of food is the unconditioned response.

The feeling of hunger in response to the smell is an unconditioned response, and a whistle sound is the conditioned stimulus.

The conditioned response (CR) is the learned response to the previously neutral stimulus.
