When making a micro-analysis of the principles of interaction between 'Heredity' and 'Environment' in the context of child development, which of the following statements most accurately defines the true nature of this interaction from the perspective of Robert Woodworth's famous equation and modern behavioral genetics?

Correct Answer: B

Both heredity and environment play a crucial role in child development. According to the renowned psychologist Robert Woodworth, development is neither solely the result of heredity nor solely of the environment, but rather the product of both (Heredity × Environment).

This implies that:

• Interdependence: Both factors interact continuously with one another.
• Joint Impact: A child's physical, mental, and emotional development is made possible only through their combined influence.

Neither factor can produce development independently, making their multiplicative interaction essential.
