cognitive development Flashcards
what are the characteristics of the preoperational stage?
mental imagery without principled thought
egocentrism
operational intelligence
fail to decenter
what is operational intelligence?
the process of solving a problem by working through logical principles
what is decenter?
broadening attention to various aspects of a problem, rather than just fixating on one
which experiments can test pre-operational thinking?
conservation
class inclusion
what is conservation?
understanding that changing the form or location of an object doesn’t change the object’s mass, volume or amount
what is class inclusion?
the ability to simultaneously classify objects into multiple categories, eg) more ducks or black ducks
what tasks does a child struggle with in the preoperational stage?
class inclusion
conservation
what are the characteristics of the concrete operational stage?
give correct answer in conservaton tasks but principled thought is confined to real life problems
what are three justifications for conservation?
compensation
inversion
identity
what are the characteristics of the formal operational stage?
principled thought is applied to abstract problems
systematic logical thinking and reasoning, eg) can recognise factors influencing pendulum speed using hypothetico-deductive reasoning
who argued against Piaget’s theory?
Donaldson
what does Donaldson argue against Piaget’s theory?
if problems are rephrased, children can pass conservation tasks earlier than previously thought
what are schemes?
mental operations guiding actions, which allow us to work in a principled way
what is assimilation?
learner applies an existing scheme to a novel task
what is accomodation?
modifying a scheme to an environmental change
