Final answer:
B. F. Skinner is the psychologist who believed that we demonstrate consistent behavior patterns because of the development of certain response tendencies through learning and environmental influences. Skinner's theory of operant conditioning emphasizes that behaviors are shaped by reinforcements and punishments throughout our lives.
Step-by-step explanation:
The individual who believed that we demonstrate consistent behavior patterns because we have developed certain response tendencies was B. F. Skinner. Skinner's ideas revolve around the concept that our environment shapes our personality throughout our lifespan through reinforcements and punishments, rather than personality being innately determined or fixed in childhood as Freud suggested. Contrary to Freud's viewpoint that personality is largely developed in the early years of life, Skinner maintained that our behavior is motivated by the consequences we experience, which is also known as operant conditioning.
Skinner is also associated with the behavioral perspective which posits that all behavior, including consistent behavior patterns, is learned rather than inborn. He argued against biological determinism and emphasized the importance of environmental factors in shaping personality.
Another important figure in psychology, Albert Bandura, is known for proposing the concept of reciprocal determinism, which suggests a two-way interaction between a person's behavior and their environment, with cognition also playing a critical role. However, when referring to the development of consistent behavior patterns through learned response tendencies, the correct answer is B. F. Skinner.
