Piaget and Vygotsky developmental and sociocultural theories Flashcards
Why do we create developmental theories?
1) To provide a framework for understanding important phenomena
- ties things together, provides structure and coherence
2) To raise crucial questions about human nature
– predictions
3) To motivate new research studies that lead to a better understanding of children

3) To motivate new research studies that lead to a better understanding of children
Why don’t we have just one theory in developmental psychology?
Because child development is a complex and varied process, no single theory accounts for all of it
Multiple theories allow a broader appreciation of cognitive development than any one theory does by itself
Who in developmental psychology is considered a rationalist?
Plato (knowledge is innate; nativist)
Who in developmental psychology is considered an empiricist?
Locke (knowledge is learned)
Who in developmental psychology is considered a constructionist?
Piaget (neither nature or nurture, it’s an interaction between nature AND nurture)
Who proposed the constructionist theory?
Piaget
What does the constructionist theory suggest?
1) Children construct knowledge for themselves
- Children are like “little scientists” who create their own experiments to learn more about the world
2) Humans construct/build their knowledge through experiences rather than simply absorbing it
What are the 4 characteristics of Piaget’s theory?
- Constructionist
- Stage Theory
- Invariant sequence
- Universal
Development involves continuities and
discontinuities
What do continuities and discontinuities mean?
Continuities = Change during development is gradual and continuous
Discontinuities = Change during development is abrupt and involves stages of changes that produce different behaviours in different age-specific periods
List the 3 processes that work together from birth to propel development forward
1) Assimilation
2) Accommodation
3) Equilibration
What is the term used to describe the process by which people translate incoming information into a form they can understand?
Assimilation
Define assimilation
The process by which people translate incoming information into a form they can understand
What happens when infants assimilate?
They generalise a new object to another object that they already know of
e.g. Infant knowns what clowns look like (red hair, curly hair, big feet)
One day, infant sees a stranger with red curly hair and big feet
The infant thinks the stranger is a clown because they share similar characteristics to a clown
This suggests the infant has assimilated the stranger to his existing concept of a clown
What is the term used to describe the process by which people adapt current knowledge structures in response to new experiences?
Accommodation
Define accommodation
The process by which people adapt current knowledge structures in response to new experiences
What happens when infants accommodate?
Infants improve their current understanding when they go through a new experience (kind of like updating their knowledge once they learn something new)
e.g. Infants discover that when they pull their teddy bear, the bear comes closer to them
The infant tries to apply this theory to their puppy. The puppy runs away
Baby updates their knowledge based on this experience; they realise that only inanimate objects come closer when pulled
What is the term used to describe the process by which people balance assimilation and accommodation to create stable understanding?
Equilibration
Define equilibration
The process by which people balance assimilation and accommodation to create a stable understanding
What happens when infants equilibrate?
They combine the process of translating new info into info that they already understand and the process of updating their knowledge once they’re experienced something
Why is Piaget’s theory considered discontinuous?
- Hierarchical stages
- Central properties (qualitative change, broad applicability, brief transition and invariant sequence)
What does “hierarchal stages” mean in Piaget’s discontinuous theory?
That there are many developmental stages which are in order of rank/importance
What does “qualitative change” mean in Piaget’s discontinuous theory?
That children in different stages/ages think in qualitatively different ways
e.g. Children in different stages/ages view the concept of morality on an entirely different criteria
What does “broad applicability” mean in Piaget’s discontinuous theory?
The type of thinking characteristic of each stage influences children’s thinking across diverse topics and contexts
What does “brief transitions” mean in Piaget’s discontinuous theory?
Before moving on to a new developmental stage, children pass through a brief transition period
They switch between the new type of thinking from the new advanced stage and the old type of thinking from the old less-advanced stage
What are the 4 stages of Piaget’s cognitive development theory?
1) Sensorimotor
2) Pre-operational
3) Concrete
4) Formal operational
When does the sensorimotor stage occur?
From birth to 2 years
What happens during the sensorimotor stage?
Infants get to know the world through
their senses and through their actions
At which stage in Piaget’s cognitive development theory will a child do this?
Aimlessly sucking and grasping objects around them to explore the environment around them
Sensorimotor stage
At which stage in Piaget’s cognitive development theory will a child develops object permanence?
Sensorimotor stage
What happens in the sensorimotor stage?
- Children explore the world through their senses and action
- Object permanence
- A-Not-B error
- Deferred imitation
What term is used when a child has the knowledge that objects continue to exist even when they are out of view?
Object permanence
When does object permanence typically emerge?
About 8 months
Define object permanence
When a child has the knowledge that objects continue to exist even when they are out of view
(If I can’t see the object, does not mean it doesn’t exist. It just means that it’s being blocked by something)
What happens when a child has obtained object permanence?
They make the A-Not-B error
What is the A-Not-B error?
The tendency to reach to where objects were found before, rather than where they were last hidden
How long does the A-Not-B error typically last for?
Until the infant reaches about 12 months
Describe Piaget’s A-Not-B task
1) Infant had object permanence so when the experimenter hides a toy under a cup (cup A), the child lifts up the cup (cup A) to find the toy
2) The experimenter continues to hide the toy under cup A
3) The experimenter now hides the toy under cup B but the infant continues to search under cup A
What do the results of Piaget’s A-Not-B task suggest?
That the child mentally represents the object after it has disappeared from view
(They imagine that the toy is still hidden under cup A when they clearly saw that the toy has been hidden in cup B)
What is the term used to describe the repetition of other people’s behaviour a substantial time after it occurred?
Deferred imitation
Define deferred imitation
The repetition of other people’s behaviour a substantial time after it occurred
At what stage and age do children perform deferred imitation?
Sensorimotor stage
Between 18-24 months
What happens when children perform deferred imitation?
They see an adult perform a certain action but they imitate the action at a later time rather than immediately
What is the 3rd stage of Piaget’s cognitive development theory?
Concrete
What is the 2nd stage of Piaget’s cognitive development theory?
Pre-operational
What is the 1st stage of Piaget’s cognitive development theory?
Sensorimotor
What is the 4th stage of Piaget’s cognitive development theory?
Formal operational
When does the pre operational stage occur?
From 2 years - 7 years
