Final answer:
Biology and philosophy have shaped the development of psychology by providing insights into the relationship between biology and behavior, and by exploring questions about the mind and self-development.
Step-by-step explanation:
Psychology, as a relatively young science, has been shaped by both biology and philosophy. The study of biology has provided insights into how our biology influences our behavior, leading to the development of fields like biopsychology and evolutionary psychology. These fields explore the relationship between our biology, specifically the structure and function of the nervous system, and our behavior.
On the other hand, philosophy played a significant role in the early days of psychology, as it was the discipline under which the workings of the mind were considered. Questions about the nature of the mind, consciousness, and self-development were explored in a philosophical context before the emergence of psychology as a separate academic discipline. Therefore, both biology and philosophy have contributed to the development of psychology, shaping its understanding of human behavior and the mind.
