Cognitive Development II Flashcards
What was Piaget’s legacy?
It was a foundation for further investigation of cognitive development.
Piagets ideas have filtered through to modern theories of cognitive development. eg active contruction of knowledge.
And broadly speaking, children’s thinking does pass through stages.
What was Piaget’s methods and what were the limitations of these?
Piaget’s theory was based on observations of his own children, in their everyday surroundings. The problems are that there is little scientific control and the issue of response demands.
What is the violation of expectation method?
its a method in which you examine a participant’s reaction when something they think is going to happen doesn’t.
What has been found when the violation of expectation method has been used on infants?
Infants will look longer at surprising events.
How is violation of expectation used with infants?
- Infant is familiarized with an image or scene.
- Infant views new images/scenes
– are they expected or surprising?
Drawbridge experiment, who and when?
Baillargeon 1987
Method of the drawbridge experiment?
Infants are familiarised with a drawbridge rotating through 180 degrees. A block is then placed behind the drawbridge so it cannot rotate all the way.
Results of the drawbridge experiment?
Infants as young as 3.5 months will look longer at the impossible event being that the drawbridge rotates all the way- so they will be surprised that it still rotates regardless of the block.
What is the significance of the drawbridge experiment?
It contradicts Piaget’s sensorimotor stage.
How does the drawbridge experiment contradict Piaget’s sensorimotor stage?
During the experiment, the obstructing block was out of sight so the infants had to mentally represent the block… Otherwise it would not have been a surprise to them.
Also suggests that infants understand solidity (solid objects can’t pass through eachother).
What could the drawbridge experiment suggest?
That babies possibly have an innate understanding of the world.
Piaget’s stages were all encompassing- global shifts across all domains of thought. But modern research suggests that the shift to a high stage may be due to what three things?
Task factors
Familiarity and relevance
Inconsistency.
What are task factors?
When the performance of the child depends on the task at hand.
What should also be considered in relation to task factors?
How the child approaches the task for example, counting objects can help with conservation of number.
What is the significance of familiarity and relevance in cognitive development.
Performance on conservation tasks can depend on social and cultural background.
Give two examples of how familiarity and relevance can affect cognitive skills and development.
Some cultures value pottery skills and those children succeed at conservation of mass earlier than other children.
Children from inner-city areas were bad at conservation tasks if presented as a science experiment but better is presented as a con artists trick.
What is the significance of inconsistency in cognitive development?
Task performance can simply vary from one day to the next.
What did Robert Siegler argue in relation to inconsistency in cognitive development?
He argued that children select from a range of strategies when faces with a difficult problem and eventually figure out the best strategy and therefore performance will vary accordingly.
In relation to inconsistency in cognitive development, how do we see improvement and development?
There is a gradual increase in probability of success through trial and error, rather than abrupt shifts between stages.
