Week 4: Cognitive Development Piaget Flashcards
(40 cards)
What is myelination? What is a condition in which myelination is affected?
-Myelin is a fatty substance that insulates axons and speeds up transmission
-Myelination of axons continues until about age 20
-> Multiple sclerosis causes demyelination and this results in electrical impulses jumping -> motor difficulties
What differences would you see in an image looking at brain tissue of a neonate versus 6 months versus 2 years
You would see a lot more dendrites i.e. the tissue would get more and more dense with dendrites
Why is Piaget a constructivist?
-Children develop knowledge of the world through the child’s own activity
-Inbuilt tendency to adapt to new experiences
-Learn through active self-discovery
What 4 stages does piaget believe a child goes through in terms of cognitive development and what ages do they correspond with?
Sensorimotor: Birth – 2 years
Preoperational: 2–7 years
Concrete operational: 7–11 years
Formal operational: 11+
Is Piaget’s theory invariant ? What does this imply about discontinuity ?
Invariant: they always occur in a fixed order,
and no stage can be skipped.
Stages are discontinuous
Does piaget believe in one course of development?
Yes, he assumes that every child goes through the same stages
BUT the speed that the child moves through the stages is affected by genetic and environmental factors
Does piaget believe in nature or nurture ?
Both, says the speed which children move through the stages can be affected by both
Schemes
An organised way of making
sense of experience
* Cognitive structures:
* Organised patterns of action or
thought that people construct to interpret their experiences
Do schemes change with age? If so, how ?
Yes
-Action-based (motor patterns) at
first (e.g. grasping is a way to make sense of a toy)
-Later move to a mental (thinking) level
Adaptation… what is it? What two complementary processes does it contain?
The process of adjusting to the demands of the
environment.
- Adaptation involves building schemes through
direct interaction with the environment.
Involves two complementary processes:
* Assimilation
* Accommodation
Assimilation
The process by which children interpret new
experiences in terms of their existing schemes.
Accommodation
The process of creating new schemes
or adjusting old ones after noticing that our current way of thinking does not capture the environment completely.
Disequilibrium
The cognitive discomfort that occurs when you encounter new information that does not align with current schema
Equilibration
Piaget’s term for the back-and-forth
movement between equilibrium and disequilibrium.
Organisation
A process that occurs internally and does not
involve direct contact with the environment.
- Once children form new schemes, they rearrange
them and link them with other schemes to create
a strongly interconnected cognitive system
Equilibrium
Current understanding of the world i.e. no current challenges to it
-Exists before disequilibrium and then after assimilation/ accommodation processes that form a new equilibrium/ understanding of the world
Sensori motor stage
-Birth–2
* Building schemes through sensory and motor
exploration
-Includes 6 substages:
① Reflexive Schemes: Birth–1 month
② Primary circular reactions: 1–4 months
③ Secondary circular reactions: 4–8 months
④ Coordination of secondary circular reactions: 8–12 months
⑤ Tertiary circular reactions: 12–18 months
⑥ Mental representation: 18 months–2 years
- Reflexive Schemes: Birth–1 month
Newborn Reflexes
① Breathing reflex
② Eye blink/Blinking reflex
③ Rooting reflex
④ Sucking reflex
⑤ Swallowing reflex
⑥ Stepping reflex
⑦ Babinski reflex
⑧ Grasping reflex (or Palmer grasp)
⑨ Moro reflex
② Primary Circular Reactions: 1–4 months
- Babies engage in repetitive actions that are
centred on their own bodies - E.g. Repeatedly suck a thumb, kick legs or blow
bubbles
Usually happens by chance first and then is repeated because it’s pleasant
- Secondary Circular Reactions: 4–8 months
- Involves repetition of interesting acts on objects (i.e. focus on external things rather than on own bodies like primary circular reactions)
- E.g. Repeatedly shaking a rattle to make an interesting noise
Usually happens by chance first and then is repeated because it’s pleasant
- Coordination of Secondary Circular
Actions: 8–12 months
- Babies display intentional, goal-directed behavior and are combining schemas to solve more complex problems
- Babies begin to develop object permanence = The understanding that objects continue to exist when they are out of sight
- Babies will still make the A-not-B search error (i.e. object permanence is not yet perfect)
= According to Piaget, this error occurs because infants cannot yet separate an object from the actions that they use to find it
⑤ Tertiary Circular Reactions: 12–18 months
- Babies explore properties of objects by acting on them in novel ways.-> e.g. throwing plate on floor to investigate what will happen
-Able to engage properly with these types of toys : were you put the blocks through the different shaped holes. Can do this because has ability to repeat actions and vary the way they position the blocks
-Will start to look in multiple places for an object -> pass the A not B test
⑥ Mental Representation: 18 months–2 years
Toddlers:
* Arrive at solutions suddenly rather than through trial and error
* Are capable of deferred imitation (copying someone who is not right there)
* Begin to engage in make-believe play
Are piaget’s claims about the sensorimotor stage generally well accepted?
- More recent research suggests that infants display a variety of understanding earlier than Piaget believed.
i.e.
Deferred imitation could be present earlier than 18-2 years
8-11 months rarely make A not B errors
