Development refers to the changes that occur between conception and death, especially those that are orderly and remain for a reasonably long period. These changes result in behavior that is more organized, effective, and complex. Development can be divided into physical, personal, social, and cognitive aspects. It involves changes that occur naturally through maturation and genetic programming, as well as changes brought about through environmental interaction and learning. Modern developmental psychologists believe that both nature and nurture influence development, with biological factors playing a stronger role in some aspects like physical development and environmental factors more influential for other areas such as moral development. Development generally follows predictable stages and later changes build upon earlier ones, though rates and sequences can vary between individuals.

1. 1

2.  Refers to certain changes that occur between
conception and death.
 The term is applied to the changes that
appear in orderly ways and remain for a
reasonably long period of time.
 Changes, at least those that occur in early
life, are assumed to be for the better.

3.  Changes result in behavior that is more:
◦ Organized
◦ Effective
◦ Complex
 And of a higher level than behavior that
preceded the change.

4. Can be divided into a number of aspects:
 Physical
 Personal
 Social
 Cognitive

5.  Refers to changes that occur naturally and
spontaneously and that are, to a large extent,
genetically programmed. *
 Changes that emerge over time and are
relatively unaffected by the environment
(except in cases of malnutrition or severe
illness)
* Vs others brought about through learning, as
individuals interact with their environment.

6.  Is development predetermined at birth, by
hereditary factors, or do experience and other
environmental factors affect it?

7.  Today, most developmental psychologists
believe that:
 Nature… biological factors play a stronger
role in some aspects
◦ such as physical development.
 Nurture… environmental factors play a
stronger role in others
◦ such as moral development.
 Both maturation and interaction with the
environment are important.

8.  Does it follow certain predictable stages?
 Are later changes dependent on a number of
very specific earlier changes?
 Is development relatively flexible, with
changes coming in different orders to
different people?

9.  People develop at different rates.
 Development is relatively orderly.
 Development takes place gradually.
