Answer: A - B.F. Skinner’s theory states that the acquisition of new knowledge and behaviors is central to human development.
Key Takeaway: To develop, humans have to gain new knowledge and behaviors. For example, to gain the benefits of socialization with other people, a child learns to be helpful and generous. Helpful behavior encourages others to offer help in return. Similarly, gaining new knowledge through study or training develops a person’s work skills and earning potential.
