Term
Piaget's Approach To Cognitive Development
Definition
Action = Knowledge

Piaget suggested that knowledge is the product of direct motor behavior.
Term
What are the four stages in which Piaget theorized that all children pass through?
Definition
Sensorimotor

Preoperational

Concrete Operational

Formal Operational
Term
Schemes
Definition
Organized patterns of functioning that adapt and change with mental development. At first, schemes are related to physical, or sensorimotor activity. As children develop, they become more mentally based.
Term
Assimilation
Definition
The process by which people understand an experience in terms of their current stage of cognitive development.

Example: Child calls a flying squirrel a 'bird' is assimilating the squirrel into its existing scheme of bird.
Term
Accommodation
Definition
When we change our existing ways of thinking, understanding, or behaving in response to a new stimuli or events.

Example: When a child sees a flying squirrel and calls it a bird with a tail. He is beginning to accommodate knew knowledge and modify his scheme of bird.
Term
Sensorimotor Stage
Definition
The initial major stage of cognitive development, which can be broken down into six stages.

1. Simple Reflexes
2. First habits and primary circular reactions
3. Secondary circular reactions
4. Coordination of secondary circular reactions
5. Tertiary circular reactions
6. Beginnings of thought
Term
Simple Reflexes
Definition
First month of life

During this time, the various inborn reflexes are the center of the baby's physical and cognitive life. At the same time, some of the reflexes begin to accommodate the infants experience with the nature of the world.

Example: Infant who is being breastfed, but also receives supplemental bottles, may start to change the way he or she sucks.
Term
First Habits and Primary Circular Reactions
Definition
Occurs from 1 to 4 months of age. In this period, infants begin to coordinate what were separate actions into single integrated activities.

example: Infant picks up object and sucks on it.
Term
Secondary Circular Reactions
Definition
Occurs from 4 to 8 months of age. During this period a child begins to act upon the outside world. They now seek to repeat enjoyable events in their environment that were brought about by chance activity.
Term
Coordination of Secondary Circular Reactions
Definition
From 8 to 12 months

Object permanence

Baby's begin to employ goal directed behavior.

Example: Moving one toy to get the toy underneath.
Term
Tertiary Circular Reactions
Definition
From 12 to 18 months.

Schemes regarding the deliberate variation of actions that cause desirable consequences. They carry out miniature experiments to see the outcomes.

Example: Dropping a toy repeatedly.
Term
Beginnings of Thought
Definition
From 18 months to 2 years.

The capacity for mental representation or symbolic thought.

Example: A ball rolls under a piece of furniture...they can figure out that it will come out the other side.
Term
Mental Representation
Definition
Internal image of a past event or object.
Term
Deferred Imitation
Definition
a person who is no longer present is imitated later.
