cognition and development Flashcards
what does piaget’s theory say about humans?
born with innate abilities and that cognitive development occurs through a combination of these abilities and environmental interactions
discovery learning
what is equilibrium?
describes how environmental interactions motivate cognitive developments and the development of schema
what are schemas?
they are cognitive frameworks and a way of organising information and understanding the world.
what is assimilation?
adding new information to an already existing schema
what is disequilibrium?
when an experience does not fit into an already existing schema, causing confusion
the unpleasant feeling creates a motivation to learn and return to a state of equilibrium
what is accomodation?
when information doesn’t fit into an existing schema, cannot be assimilated into that schema therefore a new schema has to be created
once the schema is updated to accommodate the new experience, the child return to a state of equilibrium
what are the stages of Piaget’s intellectual development?
sensorimotor 0-2yrs 8 months object permanence
pre-operational - 2-7yrs doesn’t understand conservation or class inclusion and is egocentric
concrete operation - 7-11yrs learns conservation, class inclusion but can only be applied to physical objects they see
formal operaiton - abstract thinking - syllogisms
what supporting evidence is there for piaget’s theory?
egocentrism - three mountain, a 4yrs is not able to see from a different perspective that the doll was seeing, backing up his stages
conservation - children can’t understand volume of liquid changing shape but is still the same volume as before
class inclusion - more dogs than animals?
what are the weaknesses of piaget’s theory?
egocentrism, conservation and class inclusion
conflicting evidence - egocentrism Hughes and Policeman dolls were put in 2 quadrants and children were asked to hide so that the policeman couldn’t see them
90% of children aged 5 gave the correct answer
conservation - beads spread apart and close together, however McGarrigle and Donaldson ‘naughty teddy’ accidentally pushed the beads together, 72% of the children correctly said both rows contained the same amount
class inclusion - Siegler and Sventina found 5yrs were able to learn class inclusion when it was explained to them.
what are the problems with Piaget’s methodology?
based on unstructured observations and clinical interviews
may be biased towards Piaget’s subjective interpretations
his situations were complicated or unfamiliar to the children, therefore may not have understood what they were being asked
Piaget argued that the cognitive development came before language development. However, Vygotsky argues it’s the other way round
what is Vygotsky’s theory?
describes interactions with the environment, he emphasises social and cultural factors, interactions with others
what is a strength of Piaget’s and Vygotsky’s theories?
RWA, there theories are implemented in schools and how children develop and learn.
plowden report - Piaget theory - discovery learning
scaffolding used to help children cross ZPD to become experts.
what is ZPD?
zone of proximal development is the gap between what a children is capable of and their potential intellectual ability that is helped by a teacher or parent.
what are elementary and higher functions?
elementary - innate functions, reflexes and sense perception
higher - complex functions such as language and reasoning and understanding.
what are the stages of scaffolding?
Demonstration - shown how to do a task
marking critical - highlighting the importance of the task
direction maintenance - encouraging the child
reduction of degrees of freedom
demonstration
what is scaffolding?
when someone older helps the child to learn by providing a framework to help them solve a problem or a task
what are the strengths of Vygotsky’s theory, ZPD?
studies that support - woods observed children 3-5yrs as they built with the help of a teacher. this task was too difficult for the children to complete by themselves, but simple enough that they could do it with the help of a teacher - support for ZPD
RWA for Vygotsky?
there is practical application, teachers use scaffolding strategies to help less-able children
Van Keer and Verhaeghe - 2nd grade tutored by 5th grade children in addition to normal teaching saw greater reading improvement scores than a control group
what are the weaknesses of Vygotsky’s theory?
focusing on cultural and social factors only Vygotsky’s theory may be too reductionist and ignore individual differences.
even within culture and social environment, different children will learn at different speeds
suggests that other factors are needed to explain intellectual development - genetic or biological differences in intelligence
