Lecture: Cognitive Development Flashcards
What is cognitive development?
How an infant goes from infant to cognitively mature adult
What is the typical learning curve for grammar?
It is a U shaped grammar curve. For example, went, goed, went (they started using it correctly but then learned the rule so started using it in incorrectly, then they learn exceptions and begin using it correctly again)
What is the universal grammar theory?
The mind has a bunch of switches that get set when you learn a language as a child E.g., “subject omission switch”
What happens during the critical stage of language (age 3-5)
During this time children 2-4 new words per day to their productive vocabulary (words they can produce while talking) and twice that for understanding (they can understand the words but not produce them yet- understanding is a little better than producing). That’s 1 every one or two hours awake for years. They are learning words that they don’t hear that day
What is the sensorimotor stage?
- Birth to age 2
- Simple reflex to symbolic processing
- Progress is seen on 3 fronts: Adapting to and exploring the environment (focus on intentional behaviour). Understanding objects (object permanence). Using symbols (waving)
What is the pre operational stage?
-Age 2-6
-Use of symbols to represent objects and events
-Characterized by:
Egocentrism: difficult in seeing world from someone else’s perspective and Centration: narrowly focused thought (only one part of a problem, no conservation of liquid)
What is the concrete operational stage?
- ages 7-11
- Mental operations to solve problems and reason: e.g., induction
- Problems thinking abstractly and hypothetically
What is the formal operations stage?
- 11+
- Can apply mental operations to abstract entities
- Abstract and hypothetical thinking
What are Piaget’s lasting contributions?
- The study of cognitive development at all
- Constructivism: that children are active participants in their own development
- Counterintuitive discoveries, puzzles that other scientists needed to solve
What are some problems with Piagetian theory?
- Underestimates infants, overestimates adolescents (thought you had an adult cognitive brain at 11)
- Vague on processes and change mechanisms
- Does not account for variability (stages are not that clear cut)
- Underestimates social and cultural influences
What is Lev vygostksy’s theory?
Focus on social and cultural development
What is intersubjectivity (Vygotsky)?
shared understanding among participants of an activity
What is guided participation (Vygotsky)
cognitive growth results from children’s involvement in structured activities with other who are more skilled
What is the zone of proximal development (Vygotsky)
the difference between what a child can do alone and what they can do with help
What is Scaffolding (Vygotsky)
teaching style that matches the amount of assistance to the learner’s needs
