Kyle wants to make sure that her dog does not beg for food. She says "NO!" when he begs. She is using a) Positive punishment. b) Negative punishment. c) Positive reinforcement. d) Negative reinforcement.

Answers

Answer: Positive punishment

Explanation:

Positive punishment involves adding an aversive (bad) stimulus after an unwanted behavior to discourage the dog from repeating the behavior.

In this case, when Kyle says "NO!" when the dog begs, she is using positive punishment by yelling at the dog, which is a bad stimulus.

c, Positive reinforcement.

Positive reinforcement training uses a reward (treats, praise, toys, anything the dog finds rewarding) for desired behaviors. Because the reward makes them more likely to repeat the behavior, positive reinforcement is one of your most powerful tools for shaping or changing your dog's behavior.
