Explanation:

Analyze the meaning of 'variable' in operant conditioning schedules

In operant conditioning, reinforcement schedules are categorized as either fixed (unchanging) or variable (changing/unpredictable). Therefore, "variable" indicates that the number of responses or the amount of time between reinforcements changes.

Analyze Joey the dog's behavior in classical conditioning

Joey is conditioned to bark at a real knock on the door. She also barks at a similar but different sound (a knock on TV). Responding to a stimulus that is similar to the conditioned stimulus is known as stimulus generalization.
