a) Positive reinforcement increases the likelihood of a behavior, while negative reinforcement decreases it.
b) Both positive and negative reinforcement involve the release of dopamine in the brain.
c) Positive reinforcement involves the removal of an aversive stimulus, while negative reinforcement involves the addition of a pleasurable stimulus.
d) The brain processes positive reinforcement in the prefrontal cortex and negative reinforcement in the hippocampus.

Answer 1

Both positive and negative reinforcement involve the release of dopamine in the brain.

Step-by-step explanation:

The true statement about positive and negative reinforcement in the brain is:

b) Both positive and negative reinforcement involve the release of dopamine in the brain.

In operant conditioning, positive reinforcement increases the likelihood of a behavior by adding a pleasurable stimulus, while negative reinforcement increases the likelihood of a behavior by removing an aversive stimulus. Both positive and negative reinforcement involve the release of dopamine in the brain, which is a neurotransmitter that plays a role in motivation and reward.
