development Flashcards
developmental psychology
study of human development concerned with changes in people that begin with conception and continue throughout lifespan, involves relatively permanent changes
schema
an idea about what something is, cluster of interrelated concepts that tell us about how things function in the world
- built through active information in our environment
assimilation
interpret new experiences and information in terms of current understanding of something, cognitive process of making new info fit in with existing understanding
accomodation
changing or adjusting our schemas to include new information that cannot fit into existing schemas
sensorimotor stage
- 0-2 yrs
- babies develop understanding of world and live only in present
- object permanence: child’s ability to know and understand objects continue to exist even if the they cannot be seen or heard
- tested by presenting toys to infants then covering them up to see if they would look for them (will not look for toy when covered if less than 8mths old
preoperational stage
- 2-7yo
- not able to carry out mental operations to think logically, rapidly develop symbolic thinking
- egocentric: can only perceive the world from their point of view and assumes other people see hear and feel exactly same as them
- theory of mind: ability to understand other people can have differing opinions/views, allow us to understand others have unique beliefs/views that are different to our own, opposite of centrism
how is egocentrism measured
- 3 mountain task: child sits on one side of mountain and asked to describe what they can see then asked to describe what person on other side can see: children in preoperational stage usually describe what they can see)
- policeman task: + shaped walls are resented with a boy doll and a policeman doll, policeman is placed in various positions and the child is asked to hide the boy doll from the policeman, therefore child had to take account of two different points of view, shows that because task made sense to child and was explained well they were more likely to succeed
centration
tendency to focus on only one aspect of a situation at a time (preoperational stage)
animism
belief inanimate objects have human feelings and intentions for children in preoperational stage world of nature is alive conscious and has a purpose
concrete operational stage
- 7-11 yo
- children are able to think logically and carry out mental operations when working with concrete materials (adult like logic appears but limited to reasoning about concrete, real life situations)
conservation
(in concrete operational stage) understanding an object does not change its weight, mass, volume or area simply because it changes shape
- measured by providing two balls of plasticine of same size and roll one into a long skinny shape, child who has conservation knows there is still same amount of plasticine
classification
(concrete operational stage) able to classify groups of events by features that they have in common e.g colour, size
seriation
(in concrete operational stage) ability to order objects with respect to common properties e.g biggest to smallest
formal operational stage
- 11 yo …
- children capable of abstract thinking, does not rely on being able to see or handle concrete materials in order to reason about them
- can discuss possible outcomes of actions without having experience them
- can talk about honesty and morality
logical thinking
in formal operational stage, individuals develop strategies to work through problems systematically, developing hypothesis and testing them until a solution is found
logical thinking testing
using pendulum problem, children are provided multiple weights and lengths of string, children were asked to workout which factors (weight, length of string, height it’s released from, force) affected the rate the pendulum swings at
- children in concrete operational stage will change one or more factors in a haphazard way and rarely reached correct answer
- children in formal operational stage will systematically test factors angle them to conclude it was length of string that determined how quickly pendulum swing
Key features of piagets theory
- constructivism: children build knowledge by actively exploring and experimenting
- independent learning: children can learn many things independently without support or peer interaction
- linear progression: stages always happen in same order they can never be skipped
- unique ways of thinking: stages are characterised by unique thinking patterns
criticisms of Piaget
- underestimated young minds: lack of familiarities with situation (Donaldson 1984), Hughes policeman study (1975)
- failed to distinguish between competence and performance: Siegel (1991) lack of child’s verbal expression may mask competence in reasoning, saying correct answer may not mean that they understand why it is correct
- gave insufficient attention to social influences on performance: piaget viewed children as little scientists exploring world alone, directly opposes Vygotsky’s theory who believed cognitive growth developed from social interactions
