Which of the following is NOT a principle of development ?

The correct option is: Development is universal and cultural contents do not influence it.

Understanding Principles of Human Development:

Human development is a continuous, lifelong process that involves physical, cognitive, social, and emotional changes. Key principles governing human development include:

1. Development is Lifelong: Development occurs throughout an individual's entire lifespan, from conception until death. It does not stop at adulthood.
2. Development is Modifiable (Plastic): Skills, abilities, and characteristics can be modified or changed through practice, learning, and environmental conditions throughout life.
3. Development is Influenced by both Heredity and Environment: Development is the result of the complex interaction between biological/genetic factors (heredity) and external life experiences (environment).

Why the selected option is NOT a principle of development:

Development is deeply influenced by cultural context. Culture shapes values, beliefs, social roles, child-rearing practices, and cognitive tools. Therefore, saying that "cultural contents do not influence development" is incorrect. While certain biological milestones are common across humans, cultural context significantly shapes how development unfolds. Hence, the statement that development is strictly universal without cultural influence is NOT a valid principle of development.
