By receiving a treat for sitting, what type of consequence is primarily affecting the dog's behavior?

When a dog receives a treat for sitting, it is experiencing positive reinforcement. This form of reinforcement involves adding a pleasant stimulus, in this case, a treat, immediately after the desired behavior, which is sitting. The key aspect of positive reinforcement is that it increases the likelihood of the behavior being repeated in the future.

When a dog understands that sitting yields a reward, it is more inclined to perform that behavior again because it associates sitting with receiving something enjoyable. This principle underscores why positive reinforcement is a highly effective training method; it encourages and strengthens desirable behaviors rather than suppressing or eliminating unwanted ones.

The other options do not accurately describe the scenario. Negative punishment involves the removal of a positive stimulus to decrease a behavior, while positive punishment entails adding an unpleasant stimulus to reduce a behavior. Extinction refers to the cessation of reinforcement for a behavior, leading to a decrease in that behavior over time. None of these concepts align with the scenario of the dog sitting and receiving a treat.
