Role of infant

17 important questions on Role of infant

What is temperament according to Rothart

Temperament = constitutionally based individual differences in reactivity and self-regulation, influenced over time by heredity, maturation and experience
Constitutionally = biological bases
è stems from research that temperamental differences
· appear early in life
· have substantial heritability and
· can be observed in animals.

Why do temperament differences exist?

è From evolutionary perspective = temperamental differences exist because of environmental heterogeneity
Trade-offs
è Study of exploratory males had higher fitness in a year with high resource availability but the reverse pattern occurred in resource-poor years. Higher fitness; adult survival and offspring survival to breeding.
è Fitness of personality trait depends on; sex and ecological quality of the environment.

How can temperament be measured?

Regulation; what and how well an infant does something to regulate reactivity

for example;
how rapidly is an infant recovered?
what does an infant do to regulate reactivity?

Factoranalyses; structure of temperament in any age group covered by three factors;

1) Negative affectivity
2) Positive affectivity/ surgency
3) Effortful control

Multidimensional observation protocols

- Neonatal behavior assessment scale; observational tasks to elicit specific responses in order to construct behavior
- Different ways to respond to toy interaction

True or false

temperament are the building blocks of personality

True
temperamental tendencies form building blocks that underlie development of individual differences in personality

True or false

negative emotionality was most closely related to behavior problems when regulatory capacity was high

FALSE
negative emotionality was most closely related to behavior problems when regulatory capacity was LOW

trait by trait interactions

In a study done with siblings, what did they found with the sibling with lower self control?

Poorer outcomes; despite shared family background

CONCLUSION; interventions addressing self-control probably reduce societal costs and promote prosperity

Temperament; stable or changeable?

Constitutionally based, but to some degree shaped by the environment.
Factors like; prenatal teratogens exposure, maternal postpartum depression and fear, culture & parenting.

Temperament also affects parenting. What came out of the research with mothers

Indications that mothers with less resources may respond in a less sensitive way (RISK)to a child high in negativity, compared to mothers with more resources (CHANCE)

The knowlegde that mothers also have an impact on children temperament is used to have temperament driven interventions

Teaching parents and other caregivers about
- Temperament
- Temperament of individual child
- Strategies to foster positive behaviors and decrease negative behaviors, that fit the temperament
While only few interventions exist, results seem promising

How does low parenting quality (low sensivity and low cooperation) effect the child

- effects attachment quality
- development of child

If infants and children with more difficult (negative affectivity/ less self-regulation) only are more at risk, what is then the use of this temperamental trait from an evolutionary perspective?

è Differential susceptibility model


Dandelions = resilient children. They will always do well
Orchids = susceptible children > bepaalde omgeving nodig anders groeien ze niet

Differential susceptibility markers
- Candidate genes and dopamine receptor D4
- Physiological stress reactivity
- Temperament

For who is temperament driven intervention most helpful

- children who are difficult
- who have lower education
- who have boys

What have temperament driven intervention been shown to positively impact

- Parent and teacher knowledge
- Parent and teacher interaction with children
- Child behaviors
- Child achievement
- Classroom functioning

Temperament video (infant) important findings

Sees the toy but cant reach it (because of a doorzichtige barrier), temperament hoog ; wordt gefrustreerd. Temperament laag; geeft uiteindelijk op, niet geinteressseerd

sees scary mask/ clown mask
high temperament; wordt teveel, teveel stimulatie wordt verdrietig
low temperament; find clown mask amusing, scary mask ook prima

EEG cap
low temperament; more activity in right frontal lobe > subdud personality.
high temperament; more activity in left frontal lobe

is emotional temperament constant overtime?
amount of risk a child takes, depends on their temperament (robot, playing with stranger, jumping).
Childeren have the same temperament extreme at 4 months, 9 and 24 months

Coping video (infant) important findings

Adult helps the child control their emotions > soothing strategy used with needle test

Arm restraint study
how do babys react to this with different temperaments?
- controleren van emoties door te zuigen op arm van onderzoeker (wordt hier rustiger van)
- controleren van emoties door zichzelf te vermaken
externalizing or internalizing can be coping strategies

24 months children have some coping strategies to overcome fear themselves without help of adult (spider in researchroom!!)

emotion regulation (frustration)
different approaches used by the children to get attention and try to be less frustrated

The question on the page originate from the summary of the following study material:

  • A unique study and practice tool
  • Never study anything twice again
  • Get the grades you hope for
  • 100% sure, 100% understanding
