Which two areas are identified as the major roots of psychology?

The major roots of psychology are best identified as philosophy and natural sciences. Philosophy has historically provided the foundational questions and theoretical frameworks that explore the nature of the mind, consciousness, and human behavior. Philosophers such as Socrates, Plato, and Descartes pondered deep questions about the self, thinking processes, and what it means to know. These philosophical inquiries laid the groundwork for later psychological theories and methods.

On the other hand, natural sciences contribute to psychology through empirical approaches and the scientific method. Fields such as biology and physiology offer insights into the biological underpinnings of behavior and mental processes, enabling a more rigorous understanding of how the brain and body influence psychological states. This integration of scientific inquiry allows psychology to address questions about human behavior through observation, experimentation, and evidence-based practices.

The other options, while encompassing important disciplines, do not directly trace the foundational aspects of psychology as effectively as philosophy and the natural sciences do. Therefore, the combination of these two areas represents the major roots of psychological thought and development.
