Final answer:
A therapist aiming to help a patient unlearn fearful behavior around dogs is likely a behavioral therapist, as this approach focuses on changing potentially self-destructive behaviors through techniques like desensitization.
Step-by-step explanation:
If a therapist believed that a patient should unlearn fearful behavior around dogs, it is highly likely that the therapist is a behavioral therapist. Behavioral therapy is an approach that focuses on helping clients change potentially self-destructive behaviors and involves techniques such as desensitization or exposure therapy. Unlike behavioral therapists, humanistic therapists focus on the individual's experience and personal growth. A psychoanalyst would explore unconscious motivations and conflicts based on psychoanalytic theory, while a cognitive therapist would work on altering dysfunctional thoughts.
In reference to Pavlov's work, which is a key historical example of behavioral therapy, the 'psychic secretions' were initially an unconditioned response that turned into a conditioned response once the dog learned to associate the sound of a bell with food.
Thus, the correct answer to the question is: a) Behavioral therapist.
