Cognition and development Flashcards
Define Schema
mental representation of a situation/event that could be developed by experience.
Define assimilation
- A form of learning that involves acquiring new information - it can modify your existing schema by adding to it, or apply it to a new situation.
Define accommodation
When an existing schema has to change due to new information conflicts with the existing schema
Define Equilibration
- a balance between what is already known and incoming information
Define Disequilibrium
when learning actually takes place - this has to be experienced in order for assimilation or accommodation to occur.
- when something that goes against your schema is incountered.
Describe how schemas are thought of in terms of Piaget’s theory of cognitive development
- Children are born with a small number of schemas enough to get by with, as the child develops they develop new schemas.
Give the pros and cons of Piaget’s theory.
+:
- practical applications in educational institutions, and can perhaps teach when to use certain learning techniques at which stage. Shows that there is a use to this theory in real life.
- Beaker observation task: water being moved from a thinner and taller beaker to a shorter and stout one, 7 years old failed and said they were diff. Supports the pre-operational stage.
-:
- Piaget may have underestimated cognitive abilities of children - naughty teddy study, where children were more likely to conserve and say it was the same number of counters.
-: children, so may have used a lot inference due to poor communication skills, maybe a little bias because theory was come up with by Piaget observing his own children.
Describe ideas behind Vygotsky’s theory of cognitive development.
- idea that development is dependant on social interaction and culture
- children internalising the understandings of other people that they might see as role models
(child as apprentice)
Describe the importance of language in Vygotsky’s theory (semiotics)
- external speech —> egocentric speech —> inner speech (thought)
- This allows for high mental function
Describe what is meant by the Zone of Proximal development (ZPD)
- the difference between what the child can already do independently, and what the child can do with help from others (their potential)
Define scafolding
- when an expert (such as parent or teacher etc) provide support to a child, but then slowly withdraw that until the child can perform the task independently
Give the pros and cons of Vygotsky’s theory of cognitive development.
+:
- practical applications suggesting the importance of one-on-one tuitions or tutors, allows for child to have more of an active role.
- takes into account culture and social interaction, so is not culturally biased.
-:
- theory might be thought of as reductionist, as it only focuses on cognitions, and ignores biological limitations children face when trying to pick up new tasks.
name the ages and names of the stages of development by Piaget
- Sensori motor stage 0-2 years
- Pre-operational stage 2-7 years
- Concrete operational stage 7-11 years
- formal operational stage 11+ years.
Describe the characteristics of the sensori-motor stage.
- gain knowledge through senses and movement, can develop object permanence
Describe the characteristics of the pre-operational stage
- unable to use logic
- egocentrism
- lacks conservation
- difficulty with class inclusion
Describe the characteristics of the concrete-operational stage
- beginning to think logically
- able to conserve
- less egocentric
- tend to make mistake or be overwhelmed when asked to reason about abstract or hypothetical problems.
Describe the characteristics of the formal operational stage.
- ability to thought and reason logically.
Describe what is meant by a physical reasoning system as defined as Baillargeon
- an innate knowledge of the physical world.
- ## basic understanding of things such as object permanence, gravity, causality.
What did Baillargeon use to test the physical reasoning system?
- by using the violations of expectations research.
Briefly describe what is meant by the violations of expectations research.
- a method to measure infant knowledge of the world
- involves doing something unexpected, as children are more likely to look at it for longer (eg go against gravity or sm)
- so this is interpreted as confusion
- so this now suggests that infants have formed an understanding of the world based on innate understanding.
How does Baillargeon’s theory challenge Piaget’s?
- she suggested that children have an innate understanding of objects and how they work.
- whereas Piaget suggested that children don’t have innate understanding - they grow in stages and object permanence emerges later (at around 9 months), and conservation emerges later (around 7 years old and above)
- so Piaget underestimates the abilities of children
Define Habituation
- being shown an object to the point where the child is comfortable with the object (eg being familiar with objects) and is said to occur when the infant looks away.
Give one finding from the 3 mountains task
- 4 year old pps consistently failed to choose the correct picture for the doll’s perspective.
- showing evidence for the pre-operational stage, where they lack conservation+ are more egocentric.
give one disadvantage Vygotsky’s theory of cognitive development
- could have bias, as Vygotsky was a very different culture to Piaget, as he was a product of communism, maybe why his theory was so focused on community, but Piaget’s focused on individualist ideas
