Which factors work together to shape each child's development?

• A. Heredity and environment
• B. Only heredity
• C. Only environment
• D. Economic status

Answer: (A)

Development in children comes from a dynamic interplay between genetic inheritance and environmental experiences. Heredity sets up potential—traits like temperament, cognitive propensity, and sensitivities—while the environment provides the opportunities, care, nutrition, language input, education, culture, and resources that shape how those potentials unfold. The two influence each other: a child’s genetic makeup can affect how they respond to different environments, and positive or adverse environments can enhance or limit the expression of genetic tendencies. For instance, a curious child may grow even more in a rich, exploratory setting, whereas limited language exposure can hamper language development despite strong genetic potential. Because no single factor fully determines development, both heredity and environment together shape how a child grows. Economic status is part of the environment but does not alone explain all developmental outcomes.
