The correct answer is reciprocal determinism.

Explanation:

Behaviorism, with its emphasis on experimental methods, focuses on variables that can be observed, measured and manipulated and rejects everything that is subjective, internal and unavailable (e. g. mental). In the experimental method, the standard procedure is to manipulate one variable and then measure its effects on another. All this leads to a theory of personality that says that one's environment causes our behavior.

Bandura considered that this was a bit simple for the phenomenon he observed (aggression in adolescents) and therefore decided to add a little more to the formula: he suggested that the environment causes the behavior; True, but that behavior causes the environment too. He defined this concept with the name of reciprocal determinism: the world and the behavior of a person cause each other.
