Cogntition and Development Flashcards
cognitive delevopment
describing development of all mental processes, in particular thinking, reasoning and our understanding of world
schema
mental framework of beliefs + expectations that influence cognitive processing. developed from experience.
assimilation
form of learning - takes place when we acquire new info/more advanced understanding of object, person or idea that fits into existing schemas without making any change.
accommodation
form of learning - takes place when we acquire new info that changes our understanding of a topic to extent that we need to form 1 or more new schemas and /or radically change existing schemas to deal with new understanding.
equilibration
Experiencing a balance between existing schemas + new experiences. takes place when new info is built into our understanding of a topic - either by assimilating it into existing schema/ accommodating it by forming new one.
piaget’s theory
proposed adults don’t just know more, they think in quite a different way. cog development result of 2 influences :
maturation - effect of biological processes of ageing. as kids get older, certain mental processes become possible
environment - thro interactions with environ, kid’s understanding of world become more complex
schema - piaget
mental structure containing all of info that we have bout 1 aspect of world. as kids develop, they construct more detailed + complex mental representations of world. p believe kids born with small n.o of schemas to allow interactions w others. in infancy we thought to construct new schemas + me schema = all child’s knowledge about themselves stored. w time, we develop schema for other people, objects, abstract ideas like justice. occurs as result of interactions w environ. schema can be behavioural (e.g grasping objects) or cognitive (e.g classifying objects). p proposed 2 ways that schema can become more complex - assimilation + accommodation
assimilation
trying to understand any new info in terms of their existing knowledge bout world. occurs when. an existing scheme is used on new object.
accommodation
in response to dramatically new experiences. has to adjust to these by radically changing current schemas/ forming new ones.
equilibration
driving for these changes/adaptions is principle of equilibrium. motivated to learn when existing schemas don’t allow to make sense of something new. human mind strives to maintain sense of balance. if experience can’t be assimilated into existing schemas, then there’s a state of imbalance which is experienced as unpleasant state and indiv seeks to restore balance thro equilibriation. cog development is result of adaption between indiv’s existing schemes + environmental demands for changes.
lifespan learning
ass, acc + equil takes place thro life as our experiences present us w knowledge. some limitations on what can be learned at diff stages. a young child can’t always accommodate new experiences into new schemas cause their mind is simply not mature enough - links to CD stages
Piaget - underplaying roles of others in learning
P - P may have underplayed role of other people in learning.
E - Although Piaget don’t believe kids learn best on their own, other people aren’t main focus of his theory as he saw learning in terms of what happens in mind of the indiv .
E - However, other theories of learning + CD, and a range of research findings suggest other people r absolutely crucial to process of learning.
I - reduces validity of Plage’s work.
Piaget - language development
P - development of language is important aspect of CD
E - To P, language was just cognitive ability that developed in line with other developing abilities.
E - However, other theorists have placed a lot more importance on language development, suggesting that P may have underplayed its importance.
I - this reduces validity of piaget’s theory as it’s doesn’t acknowledge all factors affecting CD
Piaget’s theory evaluation - application to education
P - been successfully applied to education.
E - Prior to his work, classrooms had kids sat silently in rows, copying from board. replaced by activity-orientated classrooms in which children actively engage in tasks that allow them to construct own understandings.
E - change in educational practices support the theory that children learn by actively exploring their environment and forming their own mental representations of the world
I - high applicability and validity of theory as it has improved the education system
Stages of Intellectual Development
P identified 4 stages of intellectual development. Each stage is characterised by a different level of reasoning ability. Although exact ages vary between kids, all kids develop through same sequence of stages.
Object Permanence
ability to realise that object still exists when it passes out of visual field
Conservation
ability to realise quantity remains same even when appearance of object or group of objects changes.
Egocentrism
child’s tendency to only be able to see world from own point of view.
Class Inclusion
advanced classification skill in which we recognise classes of objects have subsets and are themselves subsets of larger classes
Sensorimotor Stage - (0-2yrs)
- babies focus on physical sensations + basic coordination between what they see + their body movement
- understand other people r separate objects + acquire some basic language
- object permanence develops after 8 months = belief that object still exist when it goes out of view
Pre- operational Stage - (2-7 yrs)
- can’t conserve
- r egocentric ( applied to physical objects + arguments in which kids can only appreciate their own perspective)
- find class inclusion
Concrete Operations Stage (7-11yrs)
- around 7yrs most kids can conserve + perform much better on egocentric + class inclusion tasks
- have reasoning problems = only abel to reason/operate on physical operations in their presence
- struggle to reason bout abstract ideas + to imagine objects/situations they can’t see
Formal Operations Stage (11yrs +)
- abstract reasoning develops = kids can think beyond the here + now in scientific way
- kids can focus on argument + not to be distracted by its content. formal reasoning can be tested using syllogisms
Piaget’s Stages Evalution - object permanence
P - Object permanence may occur at a much younger age than Piaget theorised
E - Bower and Wishart (1972) found infants aged 1 to 4 months continued to reach for object for up to 90 seconds after lights turned out.
E - baby may been distracted by cloth in Piaget’s original study, meaning they didn’t continue to search from object when it went out of sight.
I - reduces validity of Piaget’s work.
Piaget’s Stages Evaluation - pre-operational stage
P - p underestimated ability of children in pre-operational stage.
E - McGarrigle + Donaldson (1974) found lids aged 4 to 6 could conserve, if they weren’t put off by the way they were questioned. If counters moved accidentally by a ‘naughty teddy’ then 72% of children under 7 correctly said n.o was same as before.
E - reason kids performed poorly in P’s study was cause hearing 2 questions from researcher prompted them to change their original ans.
I - P’s tests of conservation therefore lacked validity.
Piaget’s Stages Evaluation- evidence for formal operation stage
P - evidence for formal operations stage
E - Smith et al. (1998) found that children younger than this stage struggled with syllogistic reasoning tasks such as working out “how many heads does a yellow cat have, if all yellow cats have two heads?”. lids answered with “1” when ans to this abstract task is 2.
E - They were too distracted by the content to think in a logical way.
I - validity for this stage of intellectual development
Zone of Proximal Development
gap between a child’s current level of development, defined by cognitive tasks they can perform unaided, and what they can potentially do with right help from a more expert other, who may be an adult or a more advanced child.
Scaffolding
approach to instruction that aims to support learner only when absolutely necessary i.e. to provide support framework to assist the learning process. helps learner to cross ZPD + advance as much as they can, given their stage of development.
Social + Indiv Level
saw CD as social process of learning from more experienced others (experts). every function in child’s CD appears x2. knowledge is 1st intermental (between more + less expert indiv = social level), then intramental (within mind of less expert indiv = indiv level)
Elements + Higher Mental Functions
proposed kids born w elementary mental processes such as perception + memory. these r transformed into higher mental functions like use of mathematical systems by influence of culture. elementary mental functions r biological + form of nature development. higher metal functions r exclusively human. role of culture is to transform elementary mental functions into higher.
Role of Others
learns thro problem solving experiences shared within someone else, usually parent/teacher, but also more competent peers. all people w greater knowledge than child r called experts. initially, person interacting w child assumes most of responsibility for guiding problem solving activity, but gradually this responsibility transfers to child
Role of Language
believed culture is transmitted by experts using semiotics (signs + symbols developed in certain culture). language - semiotic system of foremost importance but mathematical symbols valuable too. language + maths r means by which culture transmitted from expert to child. begin w, language takes form of shared dialogues between adult + child (pre-intellectual speech), but as child develops mental representation they begin to communicate w themselves. this way, languages (semiotics) enables intellectual development.
cultural differences in cognitive abilities
if reasoning abilities r acquired from more experienced indiv with whom child has contact, makes sense child will acquire reasoning abilities of those people. means there may be cultural differences in CD, w kids picking up the mental ‘tools’ that r most important for kid in within their physical, social + work environ. mental tools can be anything like hand eye coordination needed to hunt w bow + arrow to evaluation skills in A level psych
ZPD
region where CD takes place. V believed learning precedes development + thought learning/CD doesn’t take place in area of current development nor doesn’t take place too far ahead of what child can already do independently. in 1st instance, nothing new would be learned + in second instance, new challenges would be too far from child’s current knowledge to be useful
scaffolding
term to describe process of assisting a learner thro ZPD. expert creates a ‘scaffold’, which is gradually withdrawn when child is more able to work independently. wood, bruner + ross identified 5 aspects to scaffolding - general ways in which adult helps a child to better + understand a task
5 aspects to scaffolding
recruitment - engaging child’s interest in task
reduction of degrees of freedom - focusing child on task + where to start w solving it
direction maintenance - encouraging child to help them to stay motivated + continue trying to complete task
marking critical features - highlighting most important parts of task
demonstration - showing child how to do aspects of task
wood - noted certain strategies that experts used when scaffolding. generally, as leaner crosses ZPD, level of help given in scaffolding declines from level 5 to level 1. adult more likely to use high level of help strategies when first helping, then gradually withdrawing level of help as child grasps task
ZPD Evaluation - support
P - support for ZPD
E - Roazzi + Bryant (1988) found 4-5 yrs worked better on a ‘number of sweets’ challenge when working w than alone
E - demonstrated kids could develop more reasoning skills when working w more expert people
I - s ZPD is a valid concept
ZPD Evaluation - Indiv Differences
P - V assumed process of learning is largely same in all children
E - some kids learn best during social interaction but this may not be same for everyone
E - personality + style of info processing may have powerful effects on what sort of activities + what sort of help works for different kids
I - V’s theory therefore doesn’t take account of indiv differences
ZPoD Evaluation - Application to Education
P - V’s theory has been highly influential in education
E - Van Keer + Verhaege (2005) found 7 yrs tutored by 19 yrs, in addition
to whole class teaching, progressed further in reading than a control group who only had class teaching
E - s kids can learn more and faster w appropriate scaffolding.
I - raised expectations of what kids should be able to achieve
