Q

What are some differences in a persons brain with Alzheimer’s Disease and without?

A

1) Cerebral Cortex: shrivels up and damages areas involved in thinking, planning, and remembering. The cerebral cortex is responsible for language info and info processing
2) Ventricles filled with cerebrospinal fluid grow larger
3) Hippocamus shrinks severyly which is bad becuase it is critcal to the formattion of new memories

Q

What do theories of cognitive development explain and question

A
  • Explain how we acquire ability to learn, think, communicate and remember over time
  • question if the developing mind has stagelike or gradual changes, domain-general or domain-specific and its principle source of learning
26
Q

how does Piaget Theory see children

A
  • As constructivists ( children construct knowledge themselves )
  • they see children as active, learning many things on their own and intrinsically ( like natural) motivated to learn
27
Q

What three processes work togther in Piagets theory

A

1) Assimilation: Transalte new info into a from you already have and understand
2) Accommodation: When this new information does not fit, you need to restructure your theories
3) Equilibration: Balance assimilation and accommodation to create stable understanding

28
Q

How does Piaget’s theory see reality?

A
  • Intergrationg reality into one’s own view
  • changing ones view to better match reality
29
Q

How do the components of Piagets theory use reality in terms of childs intellignce

A
  • Equilibrium: child familiar with birds, all flying things are birds
  • Assimilation: Child sees a plane and calls it a “birdie”
  • Disequilibrium: Child notices the difference between planes and birds
  • Accommodation: Child concludes that planes are not birdies, creates new category for them
30
Q

Stages of Cognitive Development

A

1) Sensorimotor ( 0-2 yr)
2) Preoperational ( 2-7yr)
3) Concrete operational ( 7-11 yr)
4) Formal operational ( 11+ yr)

31
Q

Whats the sensorimotor stage ?

A
  • first stage in cognitive development
  • Birth to 2 years
  • infants know the world through their senses and actions
  • over this stage infants increase their ability to hold mental represenations (Mental representation is the ability for children to begin to collect mental pictures or schema, and symbols to represent objects. This happens after children have mastered object permanence)
  • Infants live largely in teh present ( Out of sight, out of mind”)
32
Q

What does Piaget say about infants in sensorimotor stage

A
  • Piagets say infants do not understand object permanence until 8 months of age
33
Q

What are three main things that occur in sensorimotor stage

A

1) object permanence
2) A-not B error
3) Deferred imitation

34
Q

What is Object Permanence

A

The knowledge that objects continue to exist even when they are out of view

35
Q

What error is in the Sensorimotor Stage

A
  • A-not-B error
  • this error is committed around 8-12 months
36
Q

What is the A-not-B-error

A

The tendency to reach to where objecrs have been found before, rathjer than to where they were last hidden

37
Q

Why do infants ( 8-12 months) make the A-not-B-error

A

The frontal lobe in charge of executive functions is immature in infants so they are unable to inhibit a previous rewarded Motor response

38
Q

What is Deffered imitation

A

occurs in the sensorimotor stage
- is the repetition of other people behaviour after a delay
- occurs around 18-24 months
- evidence of persisting metal represntaions

39
Q

What is the Preoperational Stage?

A
  • 2 to 7 years
  • represents the world through language and mental representations; can see the world from other people perspectives
  • a mix of acquisitions and limitation
    1) symbolic representations
    2) Egocentrism
    3) Contraption
    4) Lack of the conservation concept
40
Q

What is symbolic representation?

A

in the preoperational Stage
- the ability to use one thing to stand for another for an example:
* Pretend play
* Use of words, numbers etc
* use of scale models

41
Q

What is egocentrism?

A
  • apart of the preoperation stage
  • the tendency to perceive the world soleu from ones own point of view
42
Q

What is Centration?

A
  • apart of the preoperation stage
  • teh tendency to focus on a single dimension of an iobject or event (e.g, the balance scale task)
43
Q

What is conservation

A
  • apart of the preoperation stage
  • merely changing the appearance of objects does not change their key properties
44
Q

How do you test conservation?

A

1) conservation of liquid quantity
2) Conservation of solid quantity
3) Conservation of number

all three conservationss have three phases in which differnt questions are asked
phase one: “do they have the same amount of – “
phase two: “Now watch what I do” (either pours, stretches clay or spreads a number of something)
phase three: “now do they have the same amount of — or different amount of —?”

45
Q

what is concrete operational stage?

A
  • the third stage of cognitive development
46
Q

in what stage of cognitive development do children understand conversation, begin to reason logically BUT have difficulty with abstract concepts and hypotheicals

A

concrete operational stage

47
Q

when children are 7-11 years old what stage in cognitive development are they in

A

concrete operational stage

48
Q

in what stage do children 7-11 have difficulty reasoning systematically and provide an example

A
  • concrete operational stage
  • example: Pendulum problem
    (Jean Piaget’s pendulum problem is a classic cognitive development task that has been used to study children’s scientific reasoning skills. The task involves a pendulum with a weight attached to it that swings back and forth. The child is asked to determine what factors influence the speed of the pendulum. What makes a pendulum swing faster or slower?” Children have the opportunity to construct a pendulum using longer and shorter strings with heavier and lighter weights. Children in the formal operations stage can systematically manipulate various combinations of weights and lengths to observe how they influenced the speed of the swing.)
49
Q

whats the formal operational stage?

A
  • last stage of cognoitive development
  • ages 11 to adulthood
50
Q

what do children begin to do in formal operational stage

A
  • begin to think abstractly and reason hypothetically
  • are capable of systematic and scientific reasoning
  • thinking is now adultlike
51
Q

list all the pros of Piagets theory

A
  • it’s highly influential.
  • establishes children are not small adults
  • learning is an active rather than passive process
  • exploring general cognitive processes that explain multiple domains of knowledge
52
Q

list all the cons of Piagets theory

A
  • People argue that Development is more continuous
  • it probably underestimates childrens competence ( like task demands)
  • It has culturally biased methods
53
Q

Whats Vygotsky’s Sociocultural Approach

A
  • views children as social beingsl other people eager to help them learn
  • childrens developmet is continuous
  • insaists that we have a unique inclination to teach each other and to learn from each other
54
Q

how does Vygotsky’s Sociocultural approch view the developmetal process

A
  • many procces ( guided participation) are the same in all societies BUT content varies a lot from culture to culture and shapes children’s thinking accordingly
55
Q

What is intersubjectivity and give examples

A

It’s a mutual understanding that people share during communication and serves as the foundation of human cognitive developmemt

  • Joint attention: Joint attention refers to the triadic coordination of an infant and her caregiver with objects or events in the immediate environment.
  • Social referencing : child uses emotion cues from social partner to interpret new things
    ex:when an infant goes to pull a tablecloth, atop which there are plates and silverware, off the dining room table. Just before they attempt to pull it, they look to their mother who looks scared and the infant decides to not pull the cloth anymore
56
Q

Whats social scaffolding and ZDP

A
  • more competent individuals provide a temporary framework that supports children thinking at a higher level
57
Q

whats does ZDP satnd for

A

zone of proximal development

58
Q

in terms of the development on the mind, how does Piaget theory see children vs Vsgotskys theoyr ?

A
  • Piagets: see children as scientist; construe knowledge through their own explorations
  • Vygotsky: child is social beong; get help form others and surrounding culture
59
Q

how does Piaget and vygotskys theory see the length/characteristic of cognitive develoomemt

A
  • Piagets: 4 stages of cognitive development ( discontinuous) and mostly universal
  • ## Vygotskys: Continuois development; vary across cultures
60
Q

what types of changes do Piagets and Vygotskys theory have in terms of their therios of how the min devlops

A

Piagets: Qualitative

Vygotskys: Quantitative
