What does bi-directional nature of development mean?

The bi-directional nature of development refers to the concept that development is influenced by both individual factors and environmental contexts, and that these influences are reciprocal. This means that while a person's characteristics, such as genetics and personality, can affect their experiences and interactions with the environment, those environmental factors, including culture and relationships, can also shape and modify individual traits and behaviors. Essentially, development is a dynamic process where individuals and their surroundings continuously interact and influence each other.
