CHAPTER 6: Theories of Cognitive Development Flashcards
Piagets Theory
- children are like scientists
- children mentally active from birth
- make sense of the world through categories of related events, objects and knowledge called schemas
- labeled constructivist - children as constructing knowledge for themselves in response to their experiences
Piagets basic principles of cognitive development
children adapt to their environment as they develop by:
A) adding to their schemas (assimilation)
B) refining their schemas (accommodation)
Assimilation
adding to schemas
- ex. toddler has a schema for cows ( all 4 legged animals = cows)
Accommodation
Refining Schemas
- ex. Child accommodates scheme for large animals to include separate categories for cows and camels
- Sensorimotor Stage (0-2)
age 0-2
infants “think” with their eyes, ears, hands, and other sensory equipment, as they cannot yet carry out many activities mentally
substage 1: exercising reflex schemas
- infants learn to control and coordinate inborn reflexes (suck, grasp, look)
substage 2: primary circular reactions
- gain voluntary control, repeat behaviours which produce pleasant sensations
substage 3: secondary circular reactions
- actions aimed at repeating interesting effects in surrounding environment; basic imitation
substage 4: coordination of secondary circular reactions
- goal directed behaviour
- better imitation skills
- limited object permanence
substage 5: tertiary circular reactions
- varying actions; experimenting
- reflect infants curiosity
- stacking blocks, scribbling on paper
substage 6: symbolic representation
- base actions on mental representation
- problem solving, use of language
- trial and error
Preoperational Stage (age 2-7)
(2-7)
symbolic capacity
age 2 : pretend/fantasy play flourishes
age 3: play becomes less self centred, display awareness that make believe is different
- process mental schemes, but cant perform mental operations
- centration
- exhibit egocentrism
benefits to make believe play
playing house, stepping into shoes of parents or teachers
- leads to greater social competence
- learn new roles
- strengthens cognitive skills (attention, memory, creativity)
gender differences:
Girls: family relationships
Boys: adventure, fantasy, use of weapons
Drawing progressions
1) scribbles (1.5 – 2)
2) first representational forms (3-4)
3) more realistic drawings (5-6)
centration
The tendency to focus on only one feature of an object to the exclusion of all others
causes children to:
Fail tests of conservation (understanding that properties of objects remain the same, even when their outward appearance changes)
- confuses appearance and realting
egocentrism
failure to distinguish other’s viewpoints from one’s own
- often talk aloud what they are doing
- Concrete Operational Stage (7-11)
A) decentration (focusing on several aspects of a problem and relating them)
B) reversibility / conservation
- are better able to focus on multiple aspects of a problem rather than centering on just one
C) classification
- ex. sorting baseball cards by team
D) seriation
- ability to put items in order (ex. by height or weight)
E) spatial reasoning
- can draw maps of neighbourhood or school with accurate landmarks
- declining egocentrism - can think about how others perceive them, a person can feel one way but act another
- Formal Operational Stage (12-17)
- develop capacity for abstract, systematic, scientific thinking
- thinking about abstract concepts
- puns, proverbs, metaphors, analogies
- growth of social thinking (friendship, honesty, freedom)
- hypothetical scenarios (what life may look like, career choices) - Thinking in multiple dimensions
- ability to view things from more than one aspect at a time
- understand sarcasm and double entendres - hypothetico-deductive reasoning
- start with hypothesis, then deduce logical, testable infrences - propositional thought
- ability to evaluate the logic of propositions without referring to real world circumstances
- if then thinking - thinking about thinking
- metacognition
- monitoring ones own cognitve activity during thinking
main contributions of piagets theory of cog. development
- children actively construct understanding of their worlds
- vividly conveys nature of childrens thinking at different ages
when does conceptual understanding begin according to piaget
18 months
- much sooner for other developmentalists
object permanence
Understanding that objects continue to exist when out of sight (occurs earlier than Piaget believed)
Violation of expectations method
show babies an “expected” event (follows physical laws) followed by “impossible” event (violates physical laws)
categorization
By 6 months, can categorize on basis of size, shape, colour (based on visual tracking)
- reducing the enormous amount of info they encounter everyday
18 months: physically sort objects into categories
Move from perceptual (based on similar appearance) to conceptual (based on common function)
perceptual categorization
recognizing that an item belongs to a category based on its physical appearance
conceptual categorization
being able to mentally make the connection that certain items belong to a category bc they have a common function
Wynn (1992) - Counting
5-mo-o’s have knowledge of basic number concepts (e.g., can discriminate between “one” and “two”)
Cause-Effect Relationships - “theory theory”
- views children as little scientists, who derive a theory about why an event has occurred
After observing an event, children draw on innate concepts to explain, or theorize about, its cause
example: can distinguish between physical causes and psychological causes for events
Naive Biology
Understanding differences between living things and inanimate objects (usu. by age 4)
a. movement
- animals move by themselves
b. growth
- animals get bigger, inanimate objects do not
c. inheritance
- only living things have offspring that resemble their parents
d. healing
- animate things heal; inanimate have to be fixed
1C. Understanding People
- infants capable of deferred imitation as early as 6 weeks
- 6-9 months: imitate over longer delays
- Ability improves as memory storage increases
12-18: toddlers able to copy actions of their peers, adults
- can appreciate others perspectives in some situations
Theory of Mind (TOM)
The ability to think about how other people’s mental states affect their actions
- becomes more sophisticated from age 3-5
- come to realize that other people have different desires and beliefs
- tested using false-belief tasks
universal: most 3 year olds make error, 5 year old dont
-lying requires T.O.M
