Which of the following statements is/are correct regarding child development? I. A child's cognitive and social development depends only on the environment II. Heredity is the only factor influential for the development of a child III. Heredity and environment are interrelated in the development of a child IV. The relative effects of heredity and environment vary in different areas of child development. Codes:
III and IV
Modern developmental psychology treats heredity (nature) and environment (nurture) as interacting influences: genes set a range of potential, and the environment determines how much of that potential is realised. Neither factor acts alone.
Statement I is incorrect: cognitive and social development do not depend only on the environment, because inherited factors such as temperament and neural maturation also shape them.
Statement II is incorrect: heredity is not the only influential factor; nutrition, stimulation, schooling and culture strongly affect development.
Statement III is correct: heredity and environment are interrelated, each modifying the effect of the other.
Statement IV is correct: the relative weight of the two differs by area; for example, physical traits such as height are more strongly influenced by heredity, while language and social behaviour depend more on the environment.
Only III and IV are correct, so every code that includes I or II fails.
III and IV option is correct.
