What is cognitive development?
|
The construction of thought processes, including remembering, problem solving, and decision-making, from childhood through adolescence to adulthood.
|
What is a scheme?
|
An organized pattern of sensorimotor functioning
|
Assimilation
|
: the process in which people understand an experience in terms of their current stage of cognitive development and way of thinking
|
Accommodation
|
Changes in existing ways of thinking that occur in response to encounters with new stimuli or events
|
Piaget believed that action = knowledge. What does this mean
|
Piaget suggested that knowledge is the product of direct motor behavior.
|
Sensorimotor
|
Piaget’s initial major stage of cognitive development, which can be broken into 6 substages
|
Sensorimotor substage 1
|
(first month) The various reflexes that determine the infant’s interactions with the world are at the center of the infant’s cognitive life
|
Sensorimotor substage 2
|
(1 to 4 months) Infants begin to coordinate what were separate actions into single, integrates activities
|
Sensorimotor substage 3
|
(4 to 8 months) Infants take major strides in shifting their cognitive horizons beyond themselves and begin to act in the outside world
|
Sensorimotor substage 4
|
(8 to 12 months) Infants begin to use more calculated approaches to producing event, coordinating several schemes to generate a single act
|
Sensorimotor substage 5
|
(12 to 18 months) Infants develop what Piaget regards as the deliberate variation of actions that bring desirable consequences
|
Sensorimotor substage 6
|
(18 months to 2 years) The capacity for mental representation or symbolic though
|
Preoperational stage
|
(2 years to 7) in which children’s use of symbolic thinking grows, mental reasoning emerges, and the use of concepts increases
|
Concrete operational stage
|
(7 to 12) characterized by the active, and appropriate, use of logic.
|
Formal operational stage
|
(12 to 15) people develop the ability to think abstractly
