Q

what is the brain maturation view on development?

A

-Changes in skill depend on what has matured in the brain
-Supported by the fact that the consistent order of the milestones is universal regardless of experience
-The fact that we can speed up these milestones doesn’t support this view

Q

what is the dynamic systems view on development?

A

Motor development results from a combination of factors
-A baby’s motor abilities depend on the brain, the muscles, the environment, the task a child faces, motivation, etc…
-Explains why we can speed up and slow down milestones

Q

what is color perception and what experimenter tested this?

A

-based on that we perceive color categorically

Bornstein Experiment
-4-month-old infants were habituated to a 510 nm (light green) light
-Then either a 480 nm (blue) or a 540 nm (green) light was presented
-Dishabituation only occurred for the 480 nm (blue) light

Infants categorize colors like adults do!!

62
Q

what are some contributions to developmental psychology due to Piaget’s Theory?

A

-Started field of cognitive development
-Identified key areas of thinking that change with development & time
-Changed way we think about infants and children
-Looked more at how the kids actions on things shape their development
-Profound influence on early childhood education
-Child-centered focus, discovery learning

63
Q

what are some criticisms about Piaget’s Theory?

A

-Does development proceed in stages?
-Doesn’t take into account social context
-Ages of stages not quite right (children’s abilities not as limited as Piaget thought)
-He underestimated their development

Baillargeon proved that babies succeeded on object permanence much sooner (3 mo. compared to 8 mo.)

64
Q

who is Lev Vygostsky?

A

Russian psychologist (1896-1934)
-believed that development is based on social interactions (language)
-created the Sociocultural Theory

65
Q

what is the Sociocultural Theory?

A

Cognitive processes develop through joint activities with more mature / older partners
-Guided participation
-Internalization

66
Q

what is Internalization?

A

-Process by which social becomes more personalized / individual
-Parent initially gives child instructions

EX: tying your shoes, bunny song
-parent teaches them bunny song
-Child then says these instructions out loud when child is by themselves
-Finally, child uses “inner speech”
-doesn’t need to say instruction out loud anymore, they can just do it

67
Q

what are two things needed for dialogue for cognitive development?

A

-Intersubjectivity
-Scaffolding

68
Q

what is intersubjectivity?

A

Shared understanding of a task
-both parent and child are engaged in tying their shoe

69
Q

what is scaffolding?

A

Adult adjusts assistance to fit child’s current level of performance
-HELP and ASSISTANCE

70
Q

what is the Zone of Proximal Development?

A

-Range of tasks child cannot handle alone but can do with help / scaffolding of more skilled partner
-Should NOT assist on tasks they can do by themselves
-Should provide help for tasks they can’t do without help

71
Q

what are some contributions to developmental psychology due to Vygotsky’s Theory?

A

Focus on social interactions and contexts that facilitate cognitive development
-Profound impact on education
-Cooperative learning
-Reciprocal teaching

72
Q

what is the difference b/w piaget and vygotsky’s view on development?

A

Piaget: learn through independence
Vygotsky: learn through dependence

73
Q

what are the three components of language?

A
  1. Phonology
  2. Semantics
  3. Syntax
74
Q

what is phonology?

A

-starts at birth
-Rules governing structure and sequencing of speech sounds
-Uses phonemes = speech sounds (babbling)

Rake vs lake (r vs l)

75
Q

what two ways does phonology develop?

A

-Speech perception (hear the sounds)
-Categorical perception (organize the sounds)

76
Q

what is speech perception?

A

Hearing the sounds of the language
-Categorize language!

77
Q

what is categorical perception?

A

Classification of continuous stimuli into distinct categories with sharp boundaries
-One can discriminate stimuli b/w categories but not w/in a category
EX: Can see distinguish A (blue vs green) but not B (light blue vs dark blue)

78
Q

what is the categorical perception of “Ba” and “Pa” sounds?

A

Ba and Pa sounds are different
-they are able to distinguish this due to their native language categorization that develops later

79
Q

who can distinguish more phonemes, adults or babies?

A

babies!
-“Ra” and “La” sound the same to a Japanese adult, but different to a Japanese baby

80
Q

what is Habituation-dishabituation testing paradigm?

A

-Interest of the child changes when hearing “Ba” after being habituated to the “Pa” sound
-Measured with a high amplitude sucking (HAS)

81
Q

how do they test Infant Speech Perception? (AKA when children can distinguish all languages compared to just the native language)

A

Operant Conditioning
-Baby hears sounds (Ba, Da, Pa)
-they do sounds that they should be able to distinguish in native language (Ba, Da) and sounds in other languages (Da, Dah)
-When the sound changes, they flash cool lights and the baby turns their head
-They are conditioned to turn their head to the light
-Then start to delay the light and see if they turn their head when sound changes
-If they turn without the light, they can distinguish sounds

THINK ABOUT HOW YOU SAY ROOT BEER

82
Q

what age can babies only distinguish sounds of their own language?

A

10-12 months

83
Q

what is Semantics?

A

Putting sounds together to form words with meaning
-Using morphemes = word meanings (1+ phonemes)

Mom vs moms
I vs you

84
Q

by the age of 1, how many words can they say? how about a 2yr old, 3yr old, 4yr old, 5yr old?

A

1 year = 1 word
2 years = 300 words
3 years = 1000 years
4 years = many thousands
5 years = 10,000 words

85
Q

what is the word learning problem?

A

A word could refer to infinite number of referents (can refer to anything) which makes it hard for babies to learn

“Look at the gavagai”

86
Q

what are five ways to fix the word learning problem?

A

-Joint focus of attention
-Perceptual Features of Objects
-Principle of mutual exclusivity
-Syntactic Bootstrapping
-Infant-directed speech

87
Q

what is joint focus attention?

A

When an adult and child attend to the same object
-Adults: point and look at object she is referring to, or follow child’s focus and label it for the child
-Child: seek info (why), repeat, pointing

EX: both looking at the giraffe at the zoo, labeling correctly

87
Q

what is joint focus attention?

A

When an adult and child attend to the same object
-Adults: point and look at object she is referring to, or follow child’s focus and label it for the child
-Child: seek info (why), repeat, pointing

EX: both looking at the giraffe at the zoo, labeling correctly

88
Q

what is Perceptual Features of Objects?

A

Shape bias: using object’s shape to extend label to other examples

EX: balls (orange, basketball, tennis ball)
-Go based on the shape, not the color

89
Q

what is Principle of mutual exclusivity?

A

If children hear a word they don’t’ know and need to choose b/w 2 objects, choose object for which they don’t know the name for

EX: cow, block, blob?

90
Q

what is Syntactic Bootstrapping?

A

Observing how words used in sentences to figure out meaning

EX: “Ella and Noah wugged”
“Ella wugged Noah”

91
Q

what is Infant-directed speech?

A

Making language features more noticeable
-Baby talk helps them learn language!
-Exaggerate intonation and loudness
-Simple words & phrases
-Emotionally expressive

Makes them more engaged

92
