Cog Dev Flashcards
Who was Piaget? What did he do?
He was a Swiss zoologist who developed and interest in intelligence testing and then moved into researching cog dev
He studied children informally to create a stage theory of cognitive development
According to Piaget what do children learn through?
They learn through interaction and cognitive maturation
What is ‘cognitive maturation?’
The biological unfolding of cognitive abilities
What is a ‘schema?’
A mental structure based on previous experiences that help us to formulate expectations and ‘how’ to operate in the world
They consist of ‘units of understanding’ about the world which can be behavioural or cognitive
Some are innate and some develop through interaction
What is assimilation? When does it occur?
It occurs when an individual incorporates/merges new knowledge into an existing schema, so a child is able to understand new information in terms of existing knowledge about the world
e.g. an existing schema e.g. sucking is used on a new stimulus e.g. toy
What is accommodation and assimilation driven by?
The need to restore equilibrium (balance)
What does accommodation involve?
Adapting an existing schema or developing new ones to cope with new info and restore equilibrium
It involves a child adapting an existing schema to fit new info or creating a new one
Example of accommodation
A child may have a schema or bird being that it flies, but when they come across a non-flying bird e.g. penguin, this cannot be assimilated into a schema and so they will have to accommodate their bird schema to allow for the idea that not all birds can fly
What is equilibration?
The balance achieved between existing schemas and new knowledge, if their is balance then the individual is in a state of equilibrium - all knowledge is contained in schemas
What is disequilibrium?
A state of imbalance, when new knowledge cannot be made to fit the schemas
What are the strengths of Piaget’s structures and processes? (2)
- practical applications
- evidence for the role of schemas
1) Has practical applications to education - the idea that learning is driven by disequilibrium and the motivation to classify information saw a change in education in 1960s to ‘discovery learning’ where children are encourage to explore and develop their understanding
2) Evidence to support - Fantz used picture of faces to test innate face schemas and found infants as young as 4 years old had a preference for schematic faces - assessed in amount of time spent looking at each face - validates the theory
What are the weaknesses of Piaget’s structures and processes? (2)
- reductionist
- underplayed other factors
1) Reductionist as it over simplifies the complex process of acquiring new info - Piaget also didn’t provide evidence to support the existence of accommodation and assimilation and they are difficult to measure - theory is unfalsifiable
2) Underplayed the role of culture/language and overplayed the role of biology - Piaget saw language as another ability that develops, whereas Vygotsky saw it as an essential component in cognitive understanding, Piaget also believed all children would be motivated to understand new info - not realistic as children differ - explanation is incomplete
What are the assumptions of Piaget’s stages of intellectual development?
- Stages are determined by innate, maturation changes
- The age at which stages are reached can vary, but the sequence is the same
- At each stage there are qualitative changes, not just quantitative
- Cognitive operations and structures should be integrated, but they can move across stages if stuck on one aspect
What is horizontal declage?
The ideas that is a child is stuck on one aspect of a stage they can still move across, and then build on current understanding and fill in the gaps
What are Piaget’s stages of intellectual development?
1) Sensorimotor stage
2) Preoperational stage
3) Concrete operational stage
4) Formal operational stage
What ages is a child in the sensorimotor stage? how do they learn?
From birth-2 years
They acquire knowledge through action
What ages is a child in the preoperational stage? how do they learn?
From 2-7 years
Acquire knowledge through visual perception
What ages is a child in the concrete operational stage? how do they learn?
From 7-11 years
Acquire knowledge through physical reasoning
What ages is a child in the formal operational stage? how do they learn?
11+ years
Acquire knowledge through abstract thinking
What is object permanence? What stage did Piaget name this in?
The realisation that objects have a permanent existence even when they are out of sight - named in the sensorimotor stage?
What did Piaget believe happens in the sensorimotor stage?
He believed that infants learn to co-ordinate sensory input with motor actions
He used the term ‘circular reactions’ to describe how an infant repeats actions over and over to test sensorimotor relationships
At what age and stage did Piaget believe object permanence developed and why?
He believed it developed in the sensorimotor stage at around 9 months, as this is around when perserverative search begins
