Step 1: Understanding the Concept:
Principles of development are universal laws that govern how humans grow and mature throughout their lifespan.
Step 2: Detailed Explanation:
1. Principle of Continuity: Development is a never-ending process from conception to death.
2. Principle of Sequentiality: Development follows an orderly pattern (e.g., Cephalocaudal: head to toe; Proximodistal: center to periphery).
3. Principle of Individual Differences: Every individual develops at their own unique pace, even if they follow the same sequence.
4. General to Specific: A child first exhibits generalized responses before developing specific skills (e.g., waving the whole arm before using fingers to pick up a coin).
5. Principle of Predictability: Because development is orderly, we can predict certain milestones (e.g., a child will crawl before they walk).
6. Principle of Interrelation: Physical, mental, social, and emotional developments are all linked. Delay in one often affects others.
Step 3: Final Answer:
These six principles highlight that development is a systematic, continuous, and integrated process.
