Q

What is rooting?

A

When the baby turns her head when her cheek or mouth is touched. It aids with feeding because it helps the infant find something to suck

Q

What is the Moro relfex?

A

Startle response when the infant arches his back and throws out his arms and legs, much like an adult would if we felt we were falling. It’s believed to have survival value. Seen when support for the head and neck is suddenly lost, or in response to a loud noise or sudden movement. Starts to disappear around 5 months. Absence of the reflex at birth, or reappearance after 5 months, may suggest damage to the central nervous system.

26
Q

What does cephalocaudal growth mean?

A

‘Cephalo’ - head and ‘caudal’ - tail
Growth starts at the top with the head
In infant development, the brain and skull are primary locations of growth
Infants’ heads are disproportionately large, but their bodies even out over time
Infancy is the most rapid and dynamic period of brain development across the lifespan
Connections are continually made between neurons

27
Q

What does proximodistal growth mean?

A

‘Proximo’ nearnesss and ‘distal’ - far away
Growth starts at the center and moves farther away
In infants, growth begins in the trunk area and then moves to the limbs.
Gross motor (large muscle) development happens before fine motor (dexterity) skill development

28
Q

What is a scheme?

A

An organized way of making sense of an experience, based on life experiences. Essentially a category.

29
Q

What is assimilation?

A

When new information is taken into existing schemas. Information is changed as it is learned to that it fits with the scheme.

30
Q

What is accommodation?

A

When schemas are changed to make sense of new information

Infants use both processes and may do so simultaneously.

31
Q

What are the 6 substages of the sensorimotor stage?

A 
Simple reflexes
First habits and primary circular reactions
Secondary circular reactions
Coordination of secondary circular
Tertiary circular
Internalization of schemes
32
Q

What happens in the simple reflexes stage?

A

Infant reflexes serve as building blocks to future motor skills
They also serve as building blocks to cognitive development
In this first substage, reflexes are not yet intentional - they are automatic

33
Q

What happens in the first habits and primary circular reactions stage?

A

Reflexes become more voluntary, and behaviors can become habits
Primary Circular Reaction: the baby purposefully trying to repeat/recreate a pleasurable event that occurred by chance. Primary refers to the fact that the action is self-focused.
Note: Piaget didn’t have sophisticated technology in his time. Some reflexes actually start before birth

34
Q

What happens in the secondary circular reactions stage?

A

Purposeful behaviors that are focused on the external world - for example, picking up a rattle and shaking it
Greater mobility helps with this exploration
This is, in and of itself, a scheme, because the process is the means by which the child develops mental representations of how things work.

35
Q

What happens in the coordination of secondary circular stage?

A

Behavior becomes more coordinated and goal-directed
The infant tries to get what she wants
May get frustrated and cry a lot if unsuccessful

36
Q

What happens in the tertiary circular stage?

A

Infants begin to experiment with different things - for example throwing something many times to see how it lands differently
Infant starts using a toy to interact with another toy

37
Q

What happens in the internalization of schemes stage?

A

Internal representation: the infant can think about an object without seeing the object in front of him
The infant can think about events without having to do them
Object Permanence: the understanding that an object exists even when it’s out of sight
It biologically makes sense that the child eventually begins to remember who mom and dad are
Problem: although this substage is the end of Piaget’s sensorimotor stage, infants can achieve object permanence as early as 4 months earlier than this

38
Q

Who came up with the 3 temperaments, when, and what was the name of the study?

A

Stella Chess and Alexander Thomas, in the 1950s, the New York Longitudinal Study

39
Q

How many children, and across what age range did the New York Longitudinal Study study?

A

133 children from birth to age 30

40
Q

What were the 3 facets of infant temperament?

A

Effortful control
Negative affectivity
Extraversion/surgency

41
Q

What does effortful control refer to?

A

Infant’s self-control and ability to focus

42
Q

What does negative affectivity refer to?

A

Levels of negative emotion like fear and frustration

43
Q

What does extraversion/surgency refer to?

A

Activity levels, excitement, and being sociable

44
Q

What were the three temperament types that Chess and Thomas classified?

A

Easy children
Difficult children
Slow-to-warm-up children

45
Q

Describe easy children.

A

Easily establish routines
Adaptable to schedule changes and new experiences
Tend to be fairly happy
~40% of children are easy according to Chess and Thomas

46
Q

Describe difficult children

A

Difficult to put on regular schedules
Unpredictable in mood
Do not adapt well to new people or situations
React negatively in novel situations
Cry frequently and extensively
~10% of children are difficult according to Chess and Thomas

47
Q

Describe slow-to-warm-up children

A

Inactive overall
Might look like difficult children in novel situations, but adjust slowly and improve in mood
Do not have the consistently positive moods of easy children
~15% of children are slow-to-warm-up according to Chess and Thomas

48
Q

What were the 5 temperament classifications of the Institute of Psychiatry in London study?

A 
Well-adjusted
Under-controlled
Confident
Inhibited
Reserved
49
Q

What is attachment?

A

A close emotional bond, primarily between a caregiver (more so mom than dad) and a child

50
Q

What is monotropy?

A

The innate need to attach to one main attachment figure

51
Q

What 3 attachment styles did Ainsworth classify?

A

Secure
Insecure Avoidant
Insecure ambivalent/resistant

52
Q

What is secure attachment?

A

Distressed when mother leaves
Avoidant of stranger when alone, but friendly when mother is present
Positive and happy when mother returns
Uses mother as a safe base to explore the environment

53
Q

What is insecure resistant attachment?

A

Intense distress when mother leaves
Avoids the stranger, shows fear of the stranger
Infant approaches mother, but resists contact, even pushing her away
Cries more and explores less than other two types

54
Q

What is insecure avoidant attachment?

A

No sign of distress when mother leaves
Infant is ok with the stranger and plays normally when stranger is present
Infant shows little interest when mother returns
Mother and stranger are able to comfort the infant equally well

55
Q

What 4th attachment style did Main and Solomon identify?

A

Disorganized

56
Q

What does a disorganized attachment style indicate?

A

A mix of resistant and avoidant behavior, but notable for their “dazed and confused” behaviors. Some researchers think this may be associated with child abuse

57
Q

What did Kagan believe?

A

Nature plays a key role
Temperament and genetics determine how much contact an infant needs
For example, an autistic child might not show secure attachment with her mother, but this is not due to the mother’s responsiveness

58
Q

What did Schaffer and Emerson believe?

A

Innate differences in sociability in infants. Some babies preferred cuddling more than others very early on, before much interaction had occurred to cause such differences

59
Q

What did Belsky and Rovine state?

A

Interactionist theory that argues that both the child’s temperament and parents’ response are responsible for the attachment type. Temperament may influence parents’ response

60
Q

What did Fox state?

A

Supports Kagan’s theory
Babies with an easy temperament are likely to develop secure attachments
Babies with a slow-to-warm-up temperament are likely to have insecure avoidant attachments
Babies with difficult temperaments are likely to have insecure ambivalent attachments

61
Q

What did Wolff and Van Ijzendoorn state?

A

Did a meta-analysis and determined weak correlation between parental sensitivity and attachment type, meaning that more sensitive parents had securely attached children
Critics say the correlation is only weak, which suggests there may be other reasons to explain different attachment types. Maternal sensitivity theory puts too much emphasis on the mother, and is a reductionist approach

62
Q

Why was the Strange Situation unethical?

A 
Unethical because it put children under stress - separation anxiety and stranger anxiety
Samples is biased, as it only includes middle-class American families
63
Q

What did Bowlby state?

A

Influenced by ethological theory (Lorenz/imprinting)
Children come into the world biologically pre-programmed to form attachments with others, because this will help them to survive
Monotropy: the innate need to attach to one main attachment figure
It is crucial to develop close bonds with caregivers within the first year of life
Failure to do so will result in serious emotional consequences
Believed that attachment was all-or-nothing

64
Q

What is the caregiver sensitivity hypothesis?

A

A child’s attachment style is dependent on the behavior their mother shows towards them
