Chapter 10 - Cognitive Development Play Years Flashcards
Piaget’s Preoperational Stage
• Ages 2-6
• Children are able to think symbolically – Language is a symbolic system
– Images are symbols
• But, Piaget argued these children haven’t yet achieved logical thinking (perspective taking, conservation) due to the following limitatations: centration, focus on appearance, static reasoning, and irreversibility
Centration? Example
A focus on one aspect of a situation, ignoring all others
• Egocentrism is an example of centration – Piaget’s mountain task
Conservation
Understanding that amount is conserved despite changes in appearance (pouring juice in taller cup does not make more juice)
What did Vygotsky emphasize in importance unlike Piaget?
social interactions
Scaffolding
support given that takes into account the learner’s needs and abiliAes
Zone of proximal development?
Stuff that a learner can do with help/guidance
There are many concepts children can’t “____” for themselves and must rely on others
discover
Children are fairly good at deciding whom to trust by ~ age _
4
What is an example of overimitation? Example?
When a person imitates an action that is not a relevant part of the behavior to be learned. Box experiment
Most developmental psychologists today do not refer to children’s development in terms of ____ stages, why?
Piagetian, because his work underestimated children’s abilities
Piaget vs Vygotsky
Early accounts of cognitive development focused on processes internal to the child (Piaget) vs. development through social interactions (Vygotsky)
What is theory of mind?
ability to understand that other individuals have desires, beliefs, and intentions that are different from one’s own
Representational theory of mind
Achieved when the child recognizes that
mental states are not a replica of reality.
They understand that people can hold false
beliefs
Unexpected contents task?
Crayon box with candles.
False belief task? When do children usually pass this task?
Not being able to take on someone else’s view
4yrs
At what age to children get:
Inferring goals (~_ months) – Joint attention (~_ months) – Different desires (~_ months)
6, 9, 18
Diverse desires task
Understanding that individuals can have desires and preferences different from one’s own emerges around 18 months
What develops? Why do 5-year-olds pass and 3- year-olds fail?
– Theory-Theory: children construct theories to explain what they observe. Like scientific theories, they are subject to revision based on incoming information.
– Simulation theory: we simulate others’ mental states using our own cognitive resources (i.e., we put ourselves in another’s shoes)
– Inhibition accounts: children have difficulty inhibiAng what they know
Theory of mind and Autism
Impairments may be seen in joint akenAon, akenAon following (gaze/poinAng), pretend play, communicaAon
Pass rates for false belief task of children with autism? downs? typical developing?
Why did they include downs?
85% of typically-developing children
86% of children with Down syndrome
20% of children with autism
They wanted to make sure it wasn’t just an intellectual disability
Lying with kids? Who lies most? How are their lies?
5 year olds lie more than 3 year olds and 4 year olds
5 year olds lies are more sophisticated “oh my elbow knocked it” instead of “it just happened”
How does lying relate to theory of mind?
They think to themselves “what will they believe”
Correlations exist between ToM development and:
– Birth order
– Parenting style
– Parent-child conversation
– Attachment
Why do children with older sibs show earlier false belief understanding?
The child has been teased, tormented and deceived - exposed to more types of behaviors that a parent wouldn’t expose them to
Why do deaf children of hearing parents show delays in ToM development?
They’re not getting the language input that a hearing child/child of deaf parents would get
A representational theory of mind is usually achieved around age _
4
Levels of language
– Phonetics – Lexicon (vocabulary) – Semantics – Syntax/morphology – Pragmatics/Communication
Vocabulary size of __-___ words age 2 -> ___-____ words at age 6
100-2,000
5,000-30,000
