Cognitive Development Flashcards
What are the four theories of cognitive development?
- Piaget’s theory
- Information-processing view
- Naturist view
- Learning view
What are the four stages of Piaget’s theory?
- Sensorimotor stage (0-2)
- Preoperational stage (2-7)
- Concrete operation stage (7-12)
- Formal operation stage (12+)
What knowledge is present in the sensorimotor stage?
No concept of past and future and knowledge gained through sensation and movement
What happens between 0-4m according to Piaget?
Interaction with the world via reflexes and repetition of pleasurable action
What happens between 4-8m according to Piaget?
Repetition to actions to produce desirable outcomes and formation of link of causality
What happens between 8-12m according to Piaget?
Combination of several actions to make a goal and emergence of object permanence
What is object permanence?
The ability to understand that object continues to exist even though it can no longer be seen. So, infants looking for hidden object = object permanence (8m)
What is the a-not-b error?
Infants looking for hidden objects in the first place it was hidden, not the last (disappears at around 12m)
What happens between 12-18m according to Piaget?
Trials and error experiments to see how outcomes change (better understanding of cause and effect)
What happens between 18-24m according to Piaget?
Mental representations and fully developed object permanence (deferred imitation) and beginning of symbolic thoughts.
What happens in the Preoperational stage according to Piaget?
Presence of symbolic thought, which is the ability to think about objects or events from the past or not in the immediate environment.
What does symbolic thought enables? And how is it evident?
Language acquisition and evident through ability to pretend play
What are two limitations of the preoperational stage?
- Egocentrism: perceiving the world solely from one’s perspective (shown by 2 mountains task)
- Centration: tendency to focus on a single perceptually striking feature and exclude other relevant information. Difficulty with conservation concept (2 glasses task)
When does a-not-b error disapears
12m
What happens in the concrete operational stage?
Less egocentrism and ability to reason logically about concrete object and events.
What are three abilities in children development in concrete operational stage?
- Decentration: something can stage the same even though it looks different
- Reversibility: capacity to think through a series of steps and mentally reverse actions
- Seriation: ability to order items along a quantitative dimension, such as length or weight
What is one thing children cannot do in concrete operational stage?
Abstract thinking
What is the formal operational stage?
Ability to think abstractly and engage in deductive reasoning (showed by Piaget’s pendulum task). However, this stage is not universal
According to Piaget, how do children learn?
Through brain maturation and exposure to concepts (active exploration)
What 2 strengths of Piaget’s theory?
- Good overview of cognitive development
- Applicable to education
What are 4 weaknesses of Piaget’s theory?
- Depicts children’s thinking as more consistent than it is (more incrementally than he thought)
- Theory is vague on mechanism of cognitive growth
- Children are more cognitively competent than he thinks (pendulum problem is too hard)
- Underestimates contribution of social world
What is the information processing view?
Children gradually overcome their processing limitations via improvements in cognitive skills (executive functioning skill)
What are the three basic cognitive skills needed for cognitive development according to information processing view?
- Inhibitory control (ability to ignore distraction)
- Working memory
- Cognitive flexibility (task switching)
How can inhibitory control be assessed?
Through day-nights troop task (longer time on incongruent trials)
How can cognitive flexibility be assessed?
Through dimensional card sorting task (sorting cards based on changing rules)
