A behavioral psychologist tries to train a bird to climb a tree to get a reward of a piece of fruit

At first, the bird learns how to climb the tree with its legs and beak. After a while, it starts flapping its wings and hopping around before it starts to climb. Eventually, the bird flies up to the piece of fruit, even though the use of its wings prevents it from being reinforced with the fruit. According to the Brelands' analysis of biological constraints, the bird is demonstrating _____.
A) response generalization
B) a reversion to behavior that was instinctual for it
C) the Law of Effect
Incorrect. The Law of Effect was proposed by Thorndike; since the bird isn't getting the fruit, that principle is not applicable here.
D) stimulus discrimination

Answer: B
