4.3.4 cognition and development ADVANCED INFO Flashcards
define cognitive development
a general term describing the development of all mental processes , in particular thinking reasoning and our understanding of the world
define schema according to piagets theroy of cognitive development
a mental framework of beliefs and expectations that influence cognitive processing . they develop through experience
define assimilation according to piagets theory of cognitive development
a form of learning that takes place when we aquire new information or more advanced understanding of an object , person or idea that fits into existing schemas without making any change.
define accomodation according to piagets theory of cognitive development
accomodation is a form of learning that takes place when we aquire new information or a more advanced understanding of any object , person or idea that fits into existing schemas without making any change.
define equilibration according to piagets theory of cognitive development
experiencing a balance between existing schemas and new experiences. it takes place when new information is built into our understanding of a topic - either by assimiliating it into an existing schema or accomodating it by forming a new one.
how has piagets theory of cognitive development changed our understanding of development
piagets theory has changed our understanding of how thinking develops in a way child . before piaget , people believed that the difference in thinking between adu;ts and children , was that adults knew more . piaget proposed something radically different . he claimed that adults do not just know more , they think in quite a different way .
what did piaget believe were the two influences on cognitive development
maturation
environment
explain how maturation influences cognitive development according to piagets theory of cognitive development
maturation is the effect of the biological processes of ageing . as children get older certain mental processes become possible.
explain how environment influences cognitive development according to piagets theory of cognitive development
through interactions with the environment , childrens understanding of the world becomes more complex. the more diverse your experiences in the world , the more complex your knowledge and understanding
according to piagets theory of cognitive development what did piaget believe motivates us to learn and how our knowledge develops
piaget was concerned with both what motivates us to learn (disequilibration and equilibration) and how our knowledege of the world develops (assimmilation and accomodation)
outline what is meant by schema according to piagets theory of cognitive development
a schema is a mental structure containing all the information that we have about one aspect of the world . as children develop they construct more and more detailed and complex mental representations of the world . these are stored as knowledge in the mind
outline what piaget believed about schemas in children according to his theory of cognitive development
piaget believed that children are born with a small number of schemas , just enough to allow them to interact with other people , e.g grasping reflex.
during infancy we are thought to construct a new schema , one of these is a “me-schema” , in which a childs knowledge about themself is stored.
with time we develop schema for other people , objects and more abstract ideas like morality and justice , THIS OCCURRS AS A RESULT OF INTERACTIONS WITH THE ENVIRONMENT.
give an example of a behavioural schema according to piagets theory of cognitive development
grasping an object
give an example of a cognitive schema according to piagets theory of cognitive development
classifying objects
how did piaget propose that a schema can become more complex
piaget proposed two ways a schema can become more complex , assimilation and accomodation
outline assimilation in piagets theory of cognitive development
a child initially tries to understand any new information in terms of their existing knowledge about the world. assimilation occurrs when an existing schema is used on a new object. e.g a child in a family with dogs can adapt to the existence of different dog breeds by assimilating them into their dog schema
outline accomodation in piagets theory of cognitive development
this takes place in response to dramatically new experiences . the child has to adjust to these by radically changing current schema or by forming new ones.
for example a child with a pet dog may at first think of cats as dogs e.g four legs and a tail , but they accomodate to the existence of a seperate species called cat . this involves altering the animal/pet schema to include cats and forming a new cat schema.
outline what is meant by equilibration according to piagets theory of cognitive development
the driving forces for changes/adaptation in schema is due to equilibrium . we are motivated to learn when our existing schemas do not allow us to make sense of something new.
human mind strives to maintain a sense of balance , equilibrium.
outline what is meant by disequilbrium according to piagets cognitive theory of development
if an experience cannot be assimilated into existing schemas , then there is a state of imbalance which is experienced as an unpleasant state (disequilibrium) and the individual seeks to restore balance through equilibration.
what did piaget theory of cognitive development claim cognitive development was as a result of
cognitive development is as a result of adaptation between the individuals existing schemas and environmental demands for changes.
outline what is meant by lifespan learning according to piagets theory of cognitive development
assimilation , accomodation and equilibration all take place throughout our life as our experiences present us with knowledge , however there are some limitations on what can be learned at different stages . a young child cannot always accomodate new experiences into new schemas because their mind is simply not mature enough - this links to piagets stages
outline one strength of piagets theory of cognitive development - supporting study
piaget theory suggests that children who have had similar learning experiences will form quite individual mental representations. supporting research from howe put children aged 9-12 in groups of 4 to study and discuss movements of objects down a slope. their understanding of the topic was assessed before and after the discussion . following the group discussion , children were found to have increased their level of knowledge and understanding . however the children had not come to the same conclusions or picked up the same facts about movement down a slope . this is a strength as it supports piagets idea that children learn by forming their own personal representations.
outline one strength of piagets theory of cognitive development - real world application
one strength of piagets theory is that it has been successfuly applied to education . prior to his work classrooms had children sat silently in rows , copying from the board . this has been replaced by activity orientated classrooms in which children engage in tasks which can help them construct their own understandings. the change in educational practices supports the theory that children learn by actively exploring their environment and forming their own mental representations of the world.
outline one limitation of piagets theory of cogntive development - underplaying role of others
one limitation of piagets theory is that he may have underplayed the role of other people in learning , although piaget did not believe that children learn best on their own , the role of others was not the main focus of his theory as he saw learning in terms of what happens in the mind of the individual. however other theories of learning and a range of resarch suggest that other people are absolutely crucial to the process of learning . this reduces the validity of piagets work as he may be failing to acknowledge key factors in learning which are otherwise widely supported
outline one limitation of piagets theory of cognitive development - cannot explain development in all children , biased sample
piaget saw learning as a motivated process in which children learn in order to equilbrate beause disequilbrium is such an unpleasant experience . but children vary greatly in their intellectual curiosity . it may be that piaget over estimated just how motivated children are to learning because he studied mainly children from the same nursery attached to his university . this is a biased sample as the children all came from predominantly white middle class well educated families. children from poorer backgrounds may have less educational oppurtunities may display more or less intellectual curiosity than middle or upper class children. therefore piagets theory cannot account for all cognitive development in all children
outline one limitation of piagets theory of cognitive development - underplaying role of language
one limitation of piagets theory of cognitve developemnt is that it may have underplayed the role/ importance of language. the development of language is an important aspect of cognitive development . to piaget language was just a cognitive ability that developed in line with other learning abiities . however , other theorists have placed a lot more importance on the role of language development. this is a limitation as piaget is failing to give proper recognition to a key factor in learning which is widely recognised by other psychologists. therefore reducing the validity of piagets theory
define piagets stages of intellectual development
piaget identified four stages of intellectual development . each stage is characterised by a different level of reasoning ability . although the exact ages vary between the children , all children develop through the same sequence of stages.
define object permanence - piagets stages of intellectual development
object permanence is the ability to realise that an object still exists when it passes out of the visual field
defien conservation - piagets stages of intellectual development
the ability to realise that the quantity remains the same even when the appearance of an object or group of objects changes.
define egocentrism- piagets stages of intellectual development
egocentrism is the childs tendency to only be able to see the world from their own point of view
define class inclusion - piaget stages of intellectual development
class inclusion an advanced classification skill in which we recognised that classes of objects have subsets and are themsleves subsets of larger classes.
what are the four stages of piagets stages onf intellectual development
sensorimotor stage (0-2 years)
pre-operational stage (2-7 years)
concrete operations stage (7-11 years)
formal operations stage (11 years +)
outline the sensorimotor stage of piagets stages of intellectual development
Sensorimotor stage - 0–2 years
babies Focus on physical sensations and basic co-ordination between what they see and their body movement.
Come to understand other people are separate objects and acquire some basic language.
Object permanence develops after around 8 months. This is the belief that an object still exists when it goes out of view.
outline the supporting research for sensorimotor stage - piagets stages of intellectual development
Piaget found that object permanence develops around 8 months. He hid an object under a cloth and observed whether children would continue to reach for the object. Before 8 months, the children immediately switched their attention away but after 8 months, they continued to reach for it suggesting they understood it still existed
outline one limitation of object permanence - may occurr much younger than piaget suggested
Object permanence may occur at a much younger age than Piaget theorised.
Bower and Wishart (1972) found that infants aged 1 to 4 months continued to reach for an object for up to 90 seconds after the lights were turned out.
The baby may have been distracted by the cloth in Piaget’s original study, meaning that they did not continue to search from the object when it went out of sight.
This reduces the validity of Piaget’s work.
outline pre-operational stage - piagets stages of intellectual development
pre-operational stage - 2-7 years
children cannot conserve
children are egocentric
children find class inclusion difficult
outline the supporting research for conservation in the preoperational stage - piagets stages of intellectual development
piaget showed children two rows of counters and asked them to confirm how they were the same . he then saced out one row of counters and asked if they were still the same or if there were more counters in either of the rows . pre operational stage children often said that they were no longer the samw which demonstrated that they could not conserve . this study was also demonstrated with playdough to test mass and liquid to test volume , the results were the same.
outline one limitation of research into conservation in the preoperational stage - abilities underestimated
Piaget underestimated the ability of children in the pre-operational stage.
McGarrigle and Donaldson (1974) found that children aged 4 to 6 could conserve, if they were not put off by the way they were questioned. If the counters were moved accidentally by a ‘naughty teddy’ then 72% of children under 7 correctly said the number was the same as before.
The reason that the children performed poorly in Piaget’s study was because hearing two questions from the researcher prompted them to change their original answer.
Piaget’s tests of conservation therefore lacked validity.
outline research into egocentrism in the preoperational stage - piagets stages of intellectual development
piaget and inhelder showed children a model of three mountains and placed a doll at different viewing angle to the child . they then asked the children to identify the dolls view from a set of pictures. pre operational children were not able to do this
outline one limitation of research into egocentrism in the preoperational stage - piagets stages of intellectual development - can occur before 7
There is evidence to suggest egocentrism can occur before 7 years old.
Hughes (1975) showed children a model with four walls in a cross layout. The model contained two dolls – a boy and a policeman. The policeman doll was placed at different locations and the children were asked to say whether the policeman could see the boy doll. It was found that 90% of 3½ to 5-year-olds could understand two viewpoints at the same time.
This contradicts Piaget’s claim that children could not understand another person’s viewpoint at this age.
outline research into class inclusion in the preoperational stage - piagets stages of intellectual development
piaget showed 7-8 year olds pictures of five dogs and two cats and asked whether there was more dogs or animals in the picture . children at this stage tended to say there were more dogs suggesting they could not simultaneously see a dog as a member of the dog class and the animal class.
outline one limitation of research into class inclusion in the preoperational stage - can occur earlier
There is evidence to suggest class inclusion can occur before 7 years old.
Siegler and Svetina (2006) found that children of 5 could successfully complete a similar type of task to what was done in Piaget’s original study if they were given an accurate explanation of class inclusion at the start of the experiment.
The difficulty of Piaget’s tasks meant the children could not show that they understood class inclusion. They can show this ability on tasks that are easier to understand.
outline concrete operations stage of piagets stages of intellectual development
Concrete Operations - 7–11 years
From the age of around seven most children can conserve and perform much better on tasks of egocentrism and class inclusion.
Children still have reasoning problems- they are only able to reason or operate on physical operations in their presence.
They struggle to reason about abstract ideas and to imagine objects/ situations they can not see.
outline formal operations stage of piagets stages of intellectual development
Formal Operations - 11 years +
Abstract reasoning develops- children can think beyond the here and now in a scientific way.
Children can focus on an argument and not be distracted by its content. This formal reasoning can be tested using syllogisms.
outline research into the formal operations stage of piagets stages of intellectual development
Smith et al. (1998) found that children younger than this stage struggled with syllogistic reasoning tasks such as working out “how many heads a yellow cat has if all yellow cats have two heads?”. Children answered with “one” when the answer to this abstract task is two. They were too distracted by the content to think in a logical way.
outline one limitation of research into the formal operations stage of piagets stages of intellectual development - overestimated
Piaget over-estimated the abilities of adolescents.
Bradmetz (1999) showed that out of 62 children tested at age 15, only one could reliably show formal reasoning whereas Piaget said this developed at age 11.
It is clear now that children at 11-year-old cannot think in an adult way.
outline one limitation of piagets stages of intellectual development - Domain-General vs. Domain-Specific
Piaget took a ‘domain-general’ view (that intellectual development is a single process and that all cognition develops together) of cognitive development that not all psychologists agree with.
Studies of children with autistic spectrum disorder (ASD) suggest that intellectual abilities develop independently to social cognition abilities.
This suggests that Piaget’s theory of cognitive development is not valid and that a ‘domain-specific’ theory is more appropriate for some examples of development.
define zone of proximal development
the gap between a childs current level of development , defined by the cognitive tasks they can perform unaided and what they can potentially do with the right help from a more expert other, who may be an adult or a more advanced child.
define scaffolding
an approach to instruction that aims to support a learner only when absolutely necessary e.g to provide a support a framework to assist the learning process . it helps the learner to cross the zone of proximal development and advance as much as they can , given their stage of development
explain the social and individual level of vygotskys theory of cognitive development
vygotsky saw cognitive development as a social process of learning from more experienced others - “experts”.
according to vygotsky every function in the childs cognitive development appears twice . knowledge is the first , intermental which is the social level and then intramental which is the individual level
