Janine wants to compare how quickly an animal learns with different types of reinforcers. Janine decides to see which type of reinforcer causes the fastest change in behavior: water or petting the animal. Janine is comparing:

primary and secondary reinforcers

Explanation:

Positive reinforcements add something to change behaviour, while negative reinforcements take away something. Primary reinforcers are biological. Secondary reinforcement relates to a situation in which a stimulus strengthens a behavior after historically identified with a primary reinforcer or stimulus that satisfies basic survival instincts.
