Cognition And Development Flashcards
Cognition def
Refers to the mental processes involved in gaining knowledge and comprehension
What is Piaget’s Theory of Cognitive Development?
- suggests that childrens intelligence undergoes changes as they grow. They are invariant (pass through any stages in the same sequence without skipping any).
- cognitive development in children occurs through interaction of innate capacities with environmental events. They are universal (the same for everyone, irrespective of culture)
- Piaget suggested that children sort the knowledge they acquire through their experiences and interaction into groupings known as schemas. These are the basic building blocks of intelligent behaviour.
- when new information is acquired, it can either be assimilated into existing schemas or accommodated through revising an existing schemas or creating an entirely new category of information.
What are the 4 schema development stages
- Assimilation – child builds a theory e.g. this is a cat
- Equilibrium – everything seems to fit this theory e.g. this is still a cat
- Disequilibrium – something happens to cast doubt on the theory e.g. is it a cat?
4. Accommodation – new information is added into the schema e.g. there are many cats
What are the four types of schemas and give examples for each one
- Person schemas - e.g. appearance, personality, preferences, behaviour
- Social schemas – e.g. be respectful, pay for movie tickets, don’t eat garlic
- Self schemas – e.g. future doctor, hate broccoli, smart, funny
- Event schemas – e.g. professionalism, handshake, business suit, portfolio
evaluation for Piaget‘s theory
– Real world application – has been applied to education as the main principles state that children are active, not passive learners, they need to discover for themselves, there are certain concepts that are beyond their reach until they have acquired the appropriate schemas to deal with them, teachers need to recognise this and provide appropriate materials to challenge them
- Howe et al support Piaget‘s theory that children form individual representations of the world, despite having similar learning experiences – supports the idea that they are active learners. he did a task with a rolling ball and asked children about it afterwards - each child understood it, but had individual interpretations of it.
– However, the theory focuses heavily on the child being an independent learner and fails to recognise the role of learning as a social process
– places great emphasis on internal motivation as being a key driving force for children to learn. This may be true for some children, and definitely true for his own children (too small of a sample) whom he used in his studies. This is not true for all children and the role of motivation is overstated in his theory.
- the idea of schemas lacks falsifiability as cannot be tested scientifically.
What are Piaget’s stages of cognitive development and describe each
- Sensorimotor stage – first two years:
– Physical sensations and developing some basic physical coordination
– the baby also develops an understanding that people are separate objects and they acquire some basic language
– object permanence – the understanding that objects still exist when they are out of sight. - Preoperational stage – 2 to 7 years
– The toddler is mobile and can use language but still likes adult reasoning ability
– class ilusion – the basic mathematical understanding that quantity remains constant even when the appearance of objects change
– Piaget demonstrated this in his number conservation experiments. He placed two rows of eight identical counters side-by-side. Young children correctly reason that each row of counties have the same number. However, when the counters in one of the roads were pushed closer together preoperational children struggle to conserve and usually said there were fewer counters in that row
– egocentrism – to see the world only from one’s own point of view. This was demonstrated in the three mountains task, in which children were shown three model mountains each with a different feature – across, a house or snow. A door was placed at the side of the models that it faced the scene from a different angle from the child . The child was asked to choose what the door would see from a range of pictures and preoperational children tended to find this difficult and often chose a picture that match the scene from their own point of view
– plus inclusion – children begin to understand classification – the idea that objects fall into categories - Concrete operational stage – 7 to 11 years
– Children perform much better on tasks of egocentrism and class illusion
– however, these operations are strictly concrete as they can only be applied to physical objects in the child’s presence. They still struggle to reason with abstract ideas/imagine objects/situations they cannot see - Formal operational stage – ages 12 and up
– Children are able to focus on the form of an argument and not be distracted by its content
– children are able to argue abstract ideas and are capable of scientific reasoning
The sequence of stages is universal across cultures and follow the same invariant – unchanging – order. All children go to the same stages in the same order, but not all at the same rate.
Evaluation to Piaget’s stages of intellectual development
– Research was flawed – children taking part in conservation studies may have been influenced by seeing the experiment to change the appearance of the counties or liquid
- Martin Hugues contradicted Piaget’s view of egocentrism – he found that when children were tested with imaginary situations that made more sense, children were able to imagine other perspectives much earlier than Piaget proposed
Describe how Vgotsky’s approach is similar and dissimilar to Piaget’s
- he was constructivist, like Piaget: new experiences/ understandings incorporated into existing cognitive frameworks
- piagets theory is structural, but Vygosty denies the existence of any guiding framework independant of culture and context. Vygotsky also focuses on the importance of sociability in learning, whereas Piaget focuses on the individual
What are the key points of Vgotsky’s theory
Describe the zone of proximal development, as described by Vygotsky
Describe scaffolding, as described by Vygotsky
Evidence for Vygotsky’s sociocultural theory
Evaluate Vygotsky’s theory
- Connor and Cross also supported the theory. They used a longitudinal study on children, observing them in problem-solving tasks with their mothers. Distinctive changes in the help appeared over time - mothers used less direct intervention and more hints and prompts as the child gained experience. (So ‘expert’ assistance is well described by the concept of scaffolding)
- real world application: raised expectations to a growth mindset.childrens education altered to scaffold children through their ZPD
- Dasen: research support - found that spatial awareness developed earlier in aboriginal children than Swedish children. This supports Vygotsky’s idea that learning is a social process which is therefore dependant on culture.
