Exam 2 Material Flashcards
Piaget stressed that _______________________.
children actively construct their own cognitive worlds
-children build mental structures that help them adapt
-piaget sought to discover how children at different points in development think and how systematic changes in children’s thinking occurs
Schemas
actions or mental representations that organize knowledge
Babies’ schemas are structured by ________.
simple actions
Older childrens’ schemas include ______ and ________
strategies and plans for solving problems
Assimilation
using existing schemas to incorporate new information
Accommodation
adjusting schemas to fit new information and experiences
Organization
grouping isolated behaviors and thoughts into higher-order, smoothly functioning cognitive system
-grouping schemes and behaviors into concepts
-continual refinements is part of development
Equilibration
shifting from one stage of thought to the next
Sensorimotor Stage
-birth-2 years
-infants construct an understanding of the world by coordinating sensory experiences (such as hearing and seeing) with physical, motor actions
-6 substages: simple reflexes, first habits and primary circular reactions, secondary circular reactions, coordination of secondary circular reactions, tertiary circular reactions, novelty, curiousity, and internalization of schemes
Simple Reflexes
-birth-1 month
-rooting, sucking and grasping reflexes; newborns suck reflexively when their lips are touched
First Habits and Primary Circular Reactions
-1-4 months
-repeating a body sensation first experienced by chance (ex. sucking thumb); then infants might accommodate actions by sucking their thumb differently from how they suck on a nipple
-usually brings pleasure and reward, so they keep doing it
Secondary Circular Reactions
-4-8 months
-an infant coos to make a person stay near; as the person starts to leave, the infant coos again
-come from outside, in the environment
Coordination of Secondary Circular Reactions
-8-12 months
-infant manipulates a stick in order to bring an attractive toy within reach (using other things to get what they want)
Tertiary Circular Reactions, Novelty, Curiousity
-12-18 months
-a block can be made to fall, spin, hit another object, and slide across the ground
-children love to climb, try new things, and act on the world
Internalization of Schemes
-18-24 months
-an infant who has never thrown a temper tantrum before sees a playmate throw a tantrum; the infant retains a memory of the event, them throws one himself the next day
-deferred imitation
Object Permanence
-major task of sensorimotor stage
-the understanding that object continue to exist even when they cannot be seen, heard, or touched
A-not-B Error
occurs when infants make the mistake of selecting a familiar hiding place (A) rather than a new hiding place (B) as they progress into substage 4 (coordination of secondary circular reactions)
-older infants less likely to make this mistake because their concept of object permanence is more complete
Data does not always support Piaget’s claim that certain processes are crucial in ____________________.
transitions from one stage to the next
Several theorists argue that infants’ perceptual abilities are highly developed ___________.
very early in life
-certain cognitive abilities appear to be present much earlier than piaget’s theory predicts
Evidence suggests infants see objects as _______, _______, ________, and _________ from their background, possibly at birth or shortly thereafter
bounded, unitary, solid, and separate
-definitely by 3-4 months of age
-critics of these findings suggest infants have only a very rudimentary understanding
By 1.5-2 years old, infants start to develop _______.
symbolic thought
Core Knowledge Approach
infants are born w/ domain-specific innate knowledge systems
-space, number sense, object permanence, language
-strongly influenced by evolution, infants are prewired to make sense of their world
-preverbal infants may also have a built-in sense of morality (basically born w/ ability to sense and perceive the world)
-critics argue nativists neglect the infant’s social immersion to focus on what happens in the infant’s head apart from the environment; and morality may emerge through the infants’ early interactions
Preoperational Stage
-2-7 years
-children begin to recognize the world with words, images, and drawings
-form stable concepts and begin to reason
-2 substages: symbolic function substage, intuitive thought substage
-children in this stage do not yet form operations; reversible mental actions that allow children to do mentally what they previously only did physically
Symbolic Function Substage
the child gains the ability to mentally represent an object that is not present
-between ages 2-4, the child scribbles designs representing people, houses, cars, etc.; and begins to use language and pretend play
Egocentrism
inability to distinguish between one’s own perspective and someone else’s perspective
-preschool children often show the ability to take another’s perspective on some tasks but not others
-three mountain task
Animism
belief that inanimate objects have lifelike qualities and are capable of action
Intuitive Thought Substage
the child uses primitive thought/reasoning and wants to know the answer to all sorts of questions
-between ages 4-7
-why questions signal the emergence of interest in figuring out why things are the way they are
-substage is called intuitive b/c young children seem unaware of how they know what they know
Major Tasks of Preoperational Stage
-centration
-conservation
Centration
focusing of attention on one characteristic to the exclusion of others
Conservation
awareness that altering the appearance of an object or substance does not change its basic properties
-conservation may appear earlier than piaget thought
-attention is especially important in explaining conservation
*liquid, matter, number, length
Concrete Operational Stage
-7-11 yrs
-children can perform concrete (tangible) operations and they can reason logically as long as reasoning can be applied to specific or concrete examples
-classify and divide into sets and subsets and consider interrelationships
-seriation
-transivity
Seriation
ability to order stimuli along an quantitative dimension
Transivity
ability to logically combine relations to reach certain conclusions
Formal Operational Stage
-11-15 yrs
-individuals move beyond concrete operations and think in more abstract and logical ways
-develop images of ideal circumstances
-use hypothetical-deductive reasoning
-critics point out there is more individual variation in formal operational thought than piaget envisioned
-adolescent egocentrism
*imaginary audience
*personal fable
Hypothetical-Deductive Reasoning
develop hypotheses, or best guesses, and systematically deduce which is the best path to follow in solving the problem
-tested with pendulum
Adolescent Egocentrism
heightened self-consciousness of adolescents
-reflected in beliefs that others are as interested in them as themselves are
-usually at the start of high school
Imaginary Audience
feeling one is the center attention and sensing one is on stage
Personal Fable
sense of personal uniqueness and invincibility
-danger invulnerability
-psychological invulnerability
-can be the effect of the delayed development of the prefrontal cortex
Piaget Major Idea
-assimilation
-accommodation
-object permanence
-egocentrism
-conservation
-current vision of children as active, constructive thinkers
-huge volume of research generated
-careful observations and inventive ways to discover how children act on and adapt to their world
Piaget showed cognitive changes are more likely if the _____ allows for gradual movement to the next level
context
Do all cognitive abilities come exactly as Piaget predicted?
No! Some will come earlier, some later.
-many adolescents still think in concrete operational ways or are just beginning to master formal operations
-many adults are not formal operational thinkers
-children can be trained to reason of a higher cognitive stage; and culture and education exert a strong influence
Neopiagetians argue for more emphasis on how children how use _______, ________, and _________ to process information.
attention, memory, and strategies
Lev Vygotsky
like piaget, vygotsky emphasized that children actively construct their knowledge and understanding
-emphasized the role of SOCIAL environment in stimulating cognitive development
-society provides tools to support cognitive development
-cognitive development is shaped by the cultures in which we live
Zone of Proximal Development
range of tasks that are too difficult for children to master alone but can be learned w/ guidance and assistance from adults or more-skilled children
-has lower limits and upper levels
Scaffolding
changing levels of support over the course of a teaching session
-more skilled person adjusts the amount of guidance to fit child’s current performance
*when the student is learning a new tasks, the skilled person may use direct instruction
*as the student’s competence increases, the skilled person gives less guidance
________ is an important tool of scaffolding in the ZPD.
Dialogue
-through dialogue , the child’s concepts become more systematic, logical, and rational
According to Vygotsky, children use _______ both for social communication and help them to solve tasks
speech
Private Speech
audible, used for self-regulation
-as children age, they can act w/out verbalizing, and self-talk becomes internalized into inner speech
-children use private speech more often when tasks are difficult, when they have made errors, and when they are not sure how to proceed
-children who use private speech are more socially competent than those who don’t
When do adults use private speech?
when they are overwhelmed, because it slows them down and then they calm down
Teachers should begin near the ZPD’s _______, so that the child can reach the goal w/ help and move to a higher level of skill and knowledge
upper limit
-observe the child and provide support when needed
Place education instructional in a ____________ in order to allow opportunities to learn in real-world settings.
meaningful context
Tools of Mind Curriculum
transforms the classrom with Vygotskian ideas
Social Constructivist Approach
emphasis on social contexts of learning and the construction of knowledge through social interaction
-for piaget, the endpoint is formal operational thought; for vgotsky, the endpoint differs depending on the culture
Problems with Vygotsky’s Approach
-not specific about age-related changes
-does not adequately describe how changes in socioemotional capabilities contribute to development
-overemphasized role of language
-emphasis on collaboration and guidance may have pitfalls
