8.7 Flashcards
Early researcher Jean Piaget developed his theory of cognitive development from detailed observations of infants and children, most especially his own three children.
Piaget believed that children form mental concepts or schemas as they experience new situations and events.
PIAGET’S THEORY: FOUR STAGES OF COGNITIVE DEVELOPMENT
The development of thinking, problem-solving, and memory.
Cognitive Development -
- a mental concept or framework that guides organization and interpretation of information, which forms and evolves through experiences with objects and events.
Schema
Piaget’s first stage of cognitive development, in which the infant uses its senses and motor abilities to interact with objects in the environment.
infants use their senses and motor abilities to learn about the world around them
SENSORIMOTOR STAGE [birth to age 2]
the knowledge that an object exists even when it is not in sight.
Object Permanence -
By the end of the sensorimotor stage, infants have fully developed a sense of
object permanence
Piaget’s second stage of cognitive development, in which the preschool child learns to use language as a means of exploring the world.
Time of developing language and concepts
Children no longer have to rely only on senses and motor skills but now can ask questions and explore their surroundings more fully
PREOPERATIONAL STAGE [ages 2 - 7]
Everyone else must see what the child sees, and what is important to the child must be important to everyone else, a limitation called
egocentrism
Focusing only on one feature of some object rather than taking all features into consideration is called
centration
In this conservation task, pennies are laid out in two equal lines. When the pennies are spaced out, the child who cannot yet conserve will centrate on the line with spaced-out pennies and assume that there are actually more pennies in that line.
Conservation Experiment
Preoperational children fail at conservation not only because they centrate but also because they are unable to “mentally reverse” actions. This feature of preoperational thinking is called.
irreversibility
- the inability to see the world through anyone else’s eyes.
Egocentrism
- the tendency of a young child to focus only on one feature of an object while ignoring other relevant features.
Centration
- the ability to understand that simply changing the appearance of an object does not change the object’s nature.
Conservation
- the inability of the young child to mentally reverse an action.
