Q

what is the learning in newborns?

A

32
Q

what is the rooting reflex?

A

touch around cheek and baby will orient toward touch

33
Q

what is the Moro reflex?

A

when startled by lack of support to the head, baby will flail their arms out and in

34
Q

what is the grasping reflex?

A

when the baby’s palm is touched, they squeeze in a very strong grip

35
Q

what is the brain development in babies?

A

at birth, 25% of adult weight
at 6 months, 50% of adult weight
cells become larger, neural networks from
growth rate slows in later childhood

36
Q

how does the brain develop?

A

at birth, brainstem and midbrain most developed
first areas of the cerebrum to mature
- primary sensory cortex
- primary motor cortex
last areas: associative areas of the cortex

37
Q

how does the sensory-perceptual development

A

vision:
- from 1/40th of the visual acuity of adults
at birth to 20/20 at 6 months
audition:
- phoneme discrimination exceeds that of
an adult
- disappears by 1 year of age

38
Q

what is the general growth trends?

A

cephalocaudal principal
proximodistal principal

39
Q

what is cephalocaudal principal?

A

development proceeds from head to foot
- head is larges and body develops later

40
Q

what is the proximodistal principal?

A

development proceeds from innermost to outer
- arms before fingers, torso before arms

41
Q

what is the motor development in babies?

A

most skills follow stage like sequences
- age of acquiring skill caries, sequences
does not

42
Q

what is cognition?

A

mental activities that help us function

43
Q

what is Jean Piaget’s cognitive development theory?

A

studied error in cognition by children in order to understand how they think
identified stages of cognitive development that unfold as children mature

44
Q

what is Piaget believe we created?

A

believed we created schemes to achieve understanding

45
Q

what is are schemes?

A

organized patterns of thought that represents out understanding of a concept or experience

46
Q

what are the two ways schemes are modified?

A

assimilation
accommodation

47
Q

what is assimilation schemes?

A

new experiences incorporated into what we already know

48
Q

what is accommodation schemes?

A

new experiences cause change in what we already know

49
Q

what did Piaget believe in?

A

nature and nurture
development proceeds in stages

50
Q

what is nature and nurture?

A

children grow by maturation as well by learning through interactions/ playing with the environment

51
Q

what are the stages of cognitive development?

A

sensorimotor stage
preoperational stage
concrete operational stage
formal operational stage

52
Q

what is the sensorimotor stage of cognition?

A

birth - 2 years
understanding world through sensory experiences and physical interactions with objects
begin to acquire language develop object permanence (6-8 months)

53
Q

what is object permanence?

A

understanding that object continue to exist even when they can no longer be seen

54
Q

what is preoperational stage of cognitive development

A

2-7 years
world is represented symbolically through worlds and mental images
symbolic thinking enables pretend play
some unique wats of thinking:
- don’t understand conservation
- display egocentrism
- commit scale errors

55
Q

what is the concrete operational stage of cognitive development?

A

7-11 years
easily perform basic mental operations involving tangible problems and situations
grasp conservation and other concrete transformations
difficulties with abstract problems

56
Q

what is formal operational stage?

A

11+ years
can think logically about concrete and abstract problems
able to form and test hypotheses

57
Q

what is Vygotsky’s cognitive development?

A

social interaction is important for development
children learn thinking skills by internalizing language from others and developing inner speech
viewed as building scaffolding
ideal level of instruction is the zone of proximal development

58
Q

what is Vygotsky’s scaffolding theory?

A

anything that would support kids development
supports how we think
for mentoring, language and cognitive support from parents, siblings, teachers and others

59
Q

what is zone of proximal development?

A

child can’t quite do alone but can with guidance of teacher/helper

60
Q

what is attachment?

A

strong emotional bong between children and primary caregivers (happens in first year of life)
important for survival and development
having bonds means safety and proper stimulation

61
Q

what are the attachment processes?

A

newborns: indiscriminate attachment
3 months: discriminate attachment
7-8 months: specific attachment

62
Q

what is indiscriminate attachment?

A

will attach to anyone who tends to their needs

63
Q

what is discriminate attachment?

A

can tell people apart
can tell familiar people and un familiar people

64
Q

what is specific attachment?

A

feel safe with a person and doesn’t feel safe when away from that person
anxieties can arise when away from this person

65
Q

what are the 2 types of anxieties that accompany specific attachment?

A

stranger anxiety
separation anxiety

66
Q

what is stranger anxiety?

A

6-18months
distress over contact with unfamiliar people

67
Q

what is separation anxiety?

A

1-3 years
distress from being from primary care giver
could be shaped by natural selection

68
Q

how do you determine attachment style for 1 year old?

A

the strange situation
- 8 episodes that stimulate caregiver-infant
interactions in everyday life
- infant’s behaviour is recorded to
determine the attachment style with their
caregiver

69
Q

what is secure attachment?

A

most children fall under this category
explores when mother is present and is upset when she leaves
greets mother warmly upon her return and sees her comfort

70
Q

what are the 3 types of insecure attachment?

A

anxious/ambivalent/resistant type
anxious/avoidant type
disorganized/disoriented type

71
Q

what is the anxious/ambivalent/resistant type?

A

infant clings to mom and is less likely to explore environment
upset when mom leaves and likely to remain upset when returns

72
Q

what is the anxious/avoidant type?

A

baby shows very little distress when om leaves and seems to ignore her
may be sociable with or ignore stranger

73
Q

what is the disorganized/disoriented type?

A

infant seems to approach and avoid mother
may become dazed for freeze
doesn’t know what to do when mom comes back

74
Q

what causes the different attachment styles?

A

baby’s temperament a minor influence
parenting behaviour is key factor

75
Q

what are the different parenting styles?

A

authoritarian
permissive
authoritative

76
Q

what is authoritarian parenting style?

A

parents impose rules and expect obedience
kids end up with poor social skills and low self esteem

77
Q

what is the permissive parenting style?

A

parents submit to kids desires, don’t enforce limits for set standards for kids behaviour
kids run the home
kids can become aggresive

78
Q

what is authoritative parenting style?

A

parents enforce rules, limits and standards but also explain, discuss, listen and express respect for kid’s ideas and wishes
kids grow boundaries and change them
kids seem to be more confident and high self esteem

79
Q

what is deprivation of attachment?

A

strong capacity for recovery if deprivation is over the first 2 years of life and then child is put in a good home (mostly seen in orphanages)
less chance of recovery with longer deprivation period
- difficulty forming attachments (trusting
people)
- increase anxiety and depression
- increase aggression
