Quiz 2 Flashcards
Piaget’s Theory of Cognitive Development
- Children’s thinking is significantly different from adults
- Cognition grows and develops in STAGES
- Stages are universal and in a specific order
- Children learn on their own
- Children are intrisically motivated
Stages of Piaget’s Theory
Sensorimotor: < 2yo
Pre-operational: 2-7yo
Concrete operational: 7-11yo
Formal operational: >12yo
Sensorimotor stage
- Live in the here and now
- Gain knowledge through movements and sensations
1-4months: reflexes and repeat pleasurable actions. Interest in own bodies
4-8months: repeat actions on object to produce desired outcomes. Interest in the world beyond own body. Connection between own actions and consequences in the world
8-12months: combine several actions towards goal. Intentional actions. Emergence of object permanence (defining achievment)
12-18months: trial and error experiments, understanding of cause-effect relations
18-24months: Mental representations, fully developed object-permanence, deferred imitation (copying adults later spontaneously), symbolic thoughts
Object Permanence
Knowing that objects continue to exist even out of sight
Develops around 8 months old
A-not-B error: tendency to reach for hidden object where it was last found (evidence that object-permanence is fragile). Disappears after 12 months
Pre-operational Stage
Symbolic thought
Egocentricism
Centration
Symbolic Thought
Think about objects or events, not present in the immediate environment.
Enables language acquisition
Ability to use symbolic representation
Engage in pretend play
Egocentricism
Perceiving the world from one’s own point of view only
ie. egocentric speech
Signs of progress when children start engaging in verbal arguments, shows that they are lsitening to the other
Centration
Tendency to focus on a single feature of an object, to the exclusion of the other features
Conservation concept: merely changing the appearance of an object does not change its key properties
Concrete Operational Stage
Understand conservation concept
Reversibility (think through a series of steps)
Seriation (order items in quantitative dimension)
Cognitive maps (familiar large-scale spaces)
Cannot think purely hypothetically
Formal Operational Stage
Think abstractly and reason hypothetically
Not everyone reaches this stage
Can imagine different realities
Piaget’s pendulum probelm
Test of deductive reasoning
Children under 12 performed unsystematic experiments and drew incorrect conclusions
Strengths of Piaget
- Children as active learners and learning progresses
- Good overview of children’s thinking at different ages
- Big breadth
Applied in real world by knowing that children think differently at different ages and decides how we teach them, and knowing that they learn best by interacting with their environment
Weaknesses of Piaget
- No use of scientific method
- Depict children’s thinking as more consistent than it really is
- Children are more cognitively competent than he thought
- Vague about the mechanisms
- Underestimates contribution of social world
Nativist View
Children have innate abilities that provide them with basic knowledge in evolutionary performance
These allow them to rapidly acquire additional knowledge in these domains
Domains of evolutionnary importance for the Nativist view
- Solid objects
- Understanding of physical laws
- Numbers
- Categorization
- Understanding minds of people
- Language
