characteristics of stage theory
developmental changes
accommodation
assimilation
what develops
why does it occur
stage theory: developmental changes are qualitative or quantitative
qualitative
stage theory: developmental changes are long or brief
brief
stage theory: developmental changes are broad or specific
broad
stage theory: developmental changes are domain____
general
stage theory: developmental changes are ____ tasks
conservation
stage theory: developmental changes are variant or invariant
invariant
stage theory: developmental changes are in a ___ order
specific
accommodation
modify existing schemas
schema
understanding of how things are
assimilation
incorporate existing schemas
tree and assimilation
trees are tall, green things but they are important because they provide oxygen and we need oxygen
assimilation translates incoming information so it
fits concepts you already know
stage theory: what develops
structure not content
stage theory: structure develop
how children think about something
stage theory: why does development occur
to bring about equilibrium
when old ways of thinking are no longer sufficient
going from addition to multiplication is an example of
stage theory why development occurs
information-processing theories: ___ metaphor
computer
hardware
brain and mind
memory and efficiency of thought
software
strategies and knowledge
hardware and software develop
simultaneously
information-processing theories: cognitive limitations due to
limitations in hardware and software
information-processing theories: cognitive limitations
problem solving
changes in working memory and executive functioning
working memory
actively thinking
overlapping waves theory
children are active problem solvers
overlapping waves theory is part of____ theory
information-processing
overlapping wave theories: identify
goal and potential obstacle to goal
overlapping waves: ____ to solve problems
use variety of approaches
overlapping waves: strategies are consistent or changing
changing
children are active problem solvers, meaning they have a goal and then
identify obstacles, come up with strategy
information-processing theories: emphasis on
structure and process of thought
information-processing theories: what processes involved in childrens thinking
developing working memory
information-processing theories: how does the process change over time
working memory expands
information-processing theories: how does the process change with age and experiences
strategies, trying different strategies
as you get older, new neurons, creating new ___, ____ being developed, more efficient thought
synapses, myelin
information-processing theories: development is continuous or discontinuous
continuous
information-processing theories development is continuous because
no unique periods of transition, development occurs all the time
hardware and software show incremental growth
core knowledge theories
children have innate knowledge
core knowledge theories: innate knowledge that children have
important for humans
language, physical and spatial reasoning, understand others, thinking, numbers, math, etc.
infants show more sophisticated cognition in _____ areas
core knowledge
core knowledge theories: infants ___ knowledge
have
core knowledge theories emphasis on
innate abilities
children are active problem solvers who have general learning abilities AND ______ that allow them to quickly and easily acquire the core knowledge
specialized innate abilities
core knowledge is domain ____
specific
core knowledge domain specific
knowledge is limited to specific content areas
knowledge is not domain
general
decalage
uneven development across domains
decalage example
theory of numbers is present at a few months, but theory of mind is not present until 3 or 4
core knowledge theories development is continuous or discontinuous
discontinuous
how is core knowledge theory discontinuous
either have or dont have core knowledge
before and after
core knowledge theory also focuses on
constructivism
constructivism
constructing own mindset through experiences
vygotsky sociocultural theory: characteristics of
sociocultural approaches
vygotsky sociocultural theory: focuses
others and cultures
which theory focuses on the child the least
vygotsky
vygotsky sociocultural theory: social interaction occurs in
broader sociocultural context that includes cultural tools
cultural tool
anything that relates to learning
vygotsky sociocultural theory: development is continuous or discontinuous
continuous
guided participation example
father teaching older son, younger son is learning how to learn
guided participation
helping people along to a point until they can learn for themselves
private speech
internalizing caregiver/parents’ statements
example of private speech
punch a sibling, parent says not to, keep punching until one day you reach a point where it is no longer okay
private speech: outside values are now
internal
analogical problem solving example
go to a restaurant, decide between something you have had and something new. you go for what you have had
analogical problem solving
using prior experience/examples to solve problems
analogical problem solving recognizes
parallels with earlier problems
social scaffolding
guided participation
optimal level of support
social scaffolding
social scaffolding example
learning to ride a bike: training wheels, then parent holds, then lets go
vygotsky sociocultural theory: learning is all about cooperation between
teacher, learner, community at large
ZDP
what the child can learn/achieve with some support of others
ZDP is just beyond
children ability range
vygotsky sociocultural theory: where learning occurs
ZDP
key of all social-cultural social theories is
cooperation
all four theories are talking about
cognition
the development of how we think
piaget sensorimotor stage major goal
acquiring mental representation
mental representation
the ability to represent something in the mind without sensory or motor contact
mental representation measured with
a not b
a-not-b task: young infants
do not search, just think object is gone
a-not-b: 12-18 months
search location A, but not B
when child searches A but not B, it is known as
a-not-b error
a-not-b: 18 month
search location B
according to a-not-b, mental representation is acquired at what age
18 months
depending on how the task is presented, a-not-b error can
appear or disappear
a-not-b raises questions about ____ of task
validity
development=____=____
moving from stage to stage; changes in domain-general structure of thinking
if thinking is influenced by ____ then perhaps Piaget was not measuring structural changes with a-not-b
task presentation
diamond says a-not-b is about
neural maturatio n
diamond noticed
hand-eye mismatch
older infants show error
hand-eye mismatch
on test trials, infants each at a but look at b
diamond: older infants show error
put under A, let them reach
put under B, hold them back
12 month passes without delay
12 months make error if delayed
diamond proposed that a-not b task requires
mental representation, and memory, and inhibition
diamond: a-not-b requires maturation of
prefrontal cortex
prefrontal cortex
decision making, judgement, inhibition
inhibition
preventing an action
mature prefrontal cortex
better at judgement and inhibition
the delay in a-not-b causes
them to lose focus
neural maturation
making error because brain is not developed enough yet
thelen: a-not-b is about
motor memory
a-not-b task without hidden objects
object placed on top
no hidden objetct
children still search for A
thelen: infants make or do not make error with object not hidden
make
when reaching movement was interrupted (stand up)
reduction in error
continue to do same motor activity over and over without disrupting or changing it
preservation
you lose your keys and keep checking same spot over and over because
stuck in motor loop; need to break it
berger: a-not-b is about
cognitive capacity
berger: capacity related to
task difficulty
resources for cognition
when something is new you need a lot more resources
___ changes task difficulty
expertise
do we have a lot of cognitive capacity
only certain amount
as you learn something, cognitive capacity increases or decreases
decrease
child is put in a spot, told to walk to mom over and over. mom moves spots,
infants still go to mom
more cognitive capacity=
fewer errors
less cognitive capacity=
more errors
infant stands at top of small set of stairs. mom stands at the bottom infant goes down stairs to mom. mom switches spots
infant goes down first set of stairs
A-not-b error when motor problem is difficult, but not when it is easy. Why does this pose validity problems for Piaget?
because it suggested that a-not-b is a test of cognitive capacity not mental representation
decalage in berger expriment
error on stairs, not on floor
why is decalage a problem for piaget
because changes are supposed to occur across domains
why do infants make a-not-b error: piaget
incomplete mental representations
why do infants make a-not-b error: diamond
immature prefrontal cortex, inhibition
why do infants make a-not-b error: thelen
formation of motor habits
why do infants make a-not-b error: berger
limitations on cognitive capacity
as you get older, memories
change, store in different places.
older brains ___ memories
cross reference
___ stick with you, ____ diminishes
concrete fact, ability to reason
cognitive control peaks in the
late teens, early twenties
cognitive peak is age
25
cognitive control decline is modulated by
genetics, health, fitness, trauma
bilingualism and cognitive control
enhances cognitive control in children and slows its rate of loss in older adults
cognitive tasks
color/function tasks
cards, puzzles, etc.
