Q

True or False: Infants experience exponential growth in their weight as they grow up to age 2

A

True. By the time an infant is 4 months old, their body weight has doubled. By one year, that weight has tripled and then quadrupled by the time they reach 2.

Q

How are a baby’s measurements of growth expressed and what do they mean?

A
  • A baby’s measurements are expressed in percentiles.
  • Is a comparison of the baby’s weight to other babies that are the same age.
  • Ex. If a baby is in the 50 percentile, then that means that 50% percent of babies weigh less than them and 50% weigh more than them.

  5. Tertiary Circular reactions (12 months-18 months)
  6. Mental Representations (18 months-2 years)
52
Q

What do infants in substage 1 do?

A

The infants use automatic reflexes to learn about their environment. Ex. They lick or suck anything that touches their cheek.

53
Q

What do infants in substage 2 do?

A

They replace their reflexes with voluntary movements. infants will learn new behaviors by engaging in them accidentally and then doing it again and again.

54
Q

What do infants in substage 3 do?

A

Infants will perform repeated actions to receive a favorable response from the environment. Ex. Shake a rattle and laugh

55
Q

What do infants in substage 4 do?

A

Infants develop more goal-directed behavior and object permanence.

56
Q

What do infants in substage 5 do?

A

Infants become “little scientists” by using trial-and-error methods to make sense of the world around them.

57
Q

What do infants in substage 6 do?

A

Infants use mental strategies to do things like remember something said before, engage in pretend play, and find objects that are out of their sight.

58
Q

What are holophrases?

A

One-word expressions that infants use. Shorter than actual words. Ex. An infant may say ju for juice

59
Q

What are underextensions?

A

Words that an infant may use for only one particular object (does not know that a label can extend to more than just that one object).

60
Q

True or False. The type of words that a child speaks first is universal throughout the world

A

False. Culture plays a role in the kinds of words that a child may learn first. Children in the US learn to speak nouns first while Chinese children learn to speak verbs first.

61
Q

What is naming explosion?

A

Period of rapid language growth that takes place between ages 1-2.

62
Q

What does Chomsky’s nativism theory say causes infants to develop language?

A

Nativism states that infants are naturally equipped to learn language thanks to a language acquisition device (LAD) located in their brains. Infants will develop language as long as they are exposed to it.

63
Q

What does BF Skinner’s reinforcement theory say causes infants to develop language?

A

Reinforcement theory states that language develops thanks to reinforcement (attention, words of praise, etc) that will encourage an infant to repeat the behavior. By repeating language, associations in the infant’s brains strengthen which causes them to learn language faster.

64
Q

What does the social pragmatic theory say causes infants to develop language?

A

Social pragmatic theory states that infants develop language because of their primitive need for connection with others. They do their best to master words and grammar to join the social world.

65
Q

What two emotional responses do infants exhibit at birth?

A

Attraction and withdrawal

66
Q

What is social smiling?

A

An event where infants respond with smiles to those who engage in their positive attention

67
Q

What is stranger wariness?

A

68
Q

Separation anxiety

A

The fear that infants experience when their caregiver leaves them

69
Q

When does separation anxiety first start? When does it peak?

A

It starts when infants are 7-8 months old and peaks around 14 months

70
Q

What does stranger wariness and separation anxiety represent?

A

They represent cognitive advances and growing social/emotional bonds between infant and caregiver

71
Q

What are the two components of emotional regulation?

A

Emotions as regulating and emotions as regulated

72
Q

What is “emotions as regulating”?

A

These are changes that are elicited by activated emotions. Ex. Sadness in a child eliciting a change in the parent’s response

73
Q

What is “emotions as regulated”?

A

Activated emotion is changed by deliberate actions taken by the self (ex. self-soothing) or others (ex. comfort)

74
Q

What is the most common technique for testing self-awareness in infants?

A

Rouge Test

75
Q

When does self-awareness develop in infants?

A

15 - 24 months

76
Q

What are the four types of attachment styles?

A

Secure, avoidant, resistant, and disorganized

77
Q

What does a secure attachment look like?

A

Infants feel secure enough to explore their surroundings with their parents nearby. They feel distressed when their caregiver leaves the room and happy when they return. Often seen in kids who have a caregiver that is sensitive and responsive to their needs.

78
Q

What does an avoidant attachment look like?

A

The child is unresponsive to the parent and does not care if the parent leaves. When the parent returns, the child is slow to show a positive reaction. Often seen in children who have insensitive and inattentive caregivers.

79
Q

What does a resistant attachment look like?

A

Children show clingy behavior but then reject the caregiver’s attempts to interact with them. They get disturbed and angry when their parent leaves and are not easy to comfort when they return. Is seen often in kids who caregivers are inconsistent with how responsive they are.

80
Q

What does a disorganized attachment look like?

A

Child behaves oddly when caregiver is around. They may freeze or run away from their caregiver returns. Is seen most often in kids who are abused or severely neglected.

81
Q

What does the caregiver sensitivity hypothesis state?

A

It states that differences in infant’s attachment styles are dependent on the mother’s behavior during development.

82
Q

What is the difference between temperament and personality?

A

Personality traits are learned while temperament is genetic

83
Q

What are the nine dimensions of temperament?

A
  • Activity level (Are they more active or inactive?)
  • Regularity (How predictable is the child with their sleeping, eating, and eliminating patterns?)
  • Approach-Withdrawl (Does the child react positively or negatively to new situations?)
  • Adaptability (How well does a child adapt to unfamiliar circumstances?)
  • Responsiveness (Does it take a small or large amount of stimulation to elicit a response?)
  • Reaction Intensity (Does the child show low or high energy when reacting to stimuli?)
  • Mood Quality (Is the child normally happy or unhappy?)
  • Distractibility (Is a child’s attention easily diverted by external stimuli?)
  • Persistence/Attention span (How long will a child contineu an activity despite difficulty and how long can a child maintain interst in an activity?)
84
Q

What are easy babies defined as?

A

Infants that are positive, adaptable, curious about new situations, and have moderate or low intensity emotions.

85
Q

What are difficult babies defined as?

A

Infants who have more negative moods and are slow to adapt to new situations

86
Q

What are slow to warm babies defined as?

A

Infants who are inactive, negative, and withdrawn from new situations

87
Q

What are undifferiented babies defined as?

A

Infants who show a variety of combinations of characteristics

88
Q

What is goodness of fit?

A

The interaction between a child’s characteristics and their physical and social environment.

89
Q

How can knowing about different temperaments help caregivers?

A

It can help caregivers interact with their child more efficiently because the caregiver will understand better what their child’s needs are and how their child’s “negative” traits can serve them well in other situations.

90
Q

What is the first stage of Erikson’s developmental theory that infants go through? What does it mean?

A

Trust vs. Mistrust. It means that the child will be dictating whether or not the world is a safe place based on how well their caregiver attends to their needs.

91
Q

What is the second stage of Erikson’s theory that toddlers go through?

A

Autonomy vs Shame and Doubt. Toddlers are concerned with being more independent as they explore their surroundings and test the limits of what can be said and done. Caregivers should allow their child to learn by doing but still keep them safe.
