Developmental Psychology- the study of changes that occur as as individual matures. Continuity v. stages of development Stability v. change Nature v. nurture
How much of development is the result of inheritance and how much is the result of what we have learned?
Newborns

Section 2Cognitive and
Emotional DevelopmentHow do we construct the world?
Schemas: mental representations of the world. Assimilation: try to fit the new object into this schema. Accommodation- change our schema to fit the
characteristics of the new object. Object Permanence
Before 6 months – no object permanence 7-12 months- search for the object the last place that it
was seen/will soon forget it. 12-18 months- - search for the object the last place
that it was seen/will not forget it. 18-24 months- will actively look for it.
Representational Thought
ConservationWhen a child reaches object permanence, can
now use symbols remember.
Conservation: the principle that a given quantity does not change when its appearance is changed.
Conservation happens because children are Egocentric- see and think of the world from their own standpoint.
Piaget’s Stages
1. Sensorimotor Stage: schemas that use body and sensations.
2. Preoperational Stage: use mental images or symbols to understand things.
3. Concrete Stage: Can use logical schemas…but only see things in black and white terms.
4. Formal Operations Stage: solve abstract problems.

Moral Development
What would you do?
Consider the following:
Your bank’s ATM dispenses $10,000 to you, and there is no way that this error would ever be discovered. You keep the money, but you donate half of it to the soup kitchen in your town. Should you have kept the money? How did you decide what to do?
Lawrence Kohlberg
Moral reasoning- developed moral dilemmas or situations:
Moral reasoning develops in six stages, which is arranged into three levels: Preconventional: children base decisions about right or wrong
based on the ability to avoid punishment or to gain rewards. Conventional – children/adults can understand rules and
expectations that others may have for them. Moral reasoning is based on the standards of the group or society.
Postconventional- people base their judgments of right or wrong on contractual or universal principles of morality. - Golden Rule, not everything can be applied to the same situation.
