In the study,Watson found the babies did not fear animals until loud noises were paired with their images. In other words, the children were not afraid of the sight of animals; however, fear was induced when sounds were paired with them. 

Negative reinforcement is an example of operant conditioning. This is when you take something good away to create a desired behavior. Such as taking away a child's cell phone until they clean their room. On the other hand the rest of the listed choices are incorrect. In classical conditioning you can train an animal to have a response to an unrelated stimuli. Positive reinforcement is another example of operant conditioning. This is when you give something good to create a desired behavior. An example of this is giving a child a cookie because they cleaned their room. Negative punishment is when you remove a good thing to decrease a behavior. An example of this is if you remove a child's cell phone for coming home late. Last, positive punishment is when you add something bad to decrease a behavior. An example of this is if you spank a child for misbehaving.
