Development refers to an increase in structure for better and enhanced functioning of organs. It is a complex and continuous process, thus there are some principles that need to be followed for a better understanding of the concept.
Key PointsPrinciples of development include:
Development is Life-Long/Principle of continuity:
- This principle defines that development is a life-long process as it does not stop at maturation and continues gradually until reaching its maximum growth.
Development is modifiable:
- Development may be explained as the series of overall changes in an individual due to the emergence of modified structures and functions that are the outcome of the interactions and exchanges between the organism and its environment.
Development follows a pattern:
- Prenatal (before birth) and postnatal (after birth) development of human beings follow a pattern or a predictable sequence. Physical development, motor or language development and intellectual development take place in definite sequences.
Product of hereditary and environment:
- Hereditary and environment play a vital role in determining the development of an individual as:
- all the mental and social traits depend on the environment.
- all the inborn traits, instincts, potentials, and I. Q. depends on heredity.
- Development = Heredity * Environment
Hence, it could be concluded that development is governed and determined by culture alone is not a principle of development.
