Q

linear regression analysis:
b

A

b=the slope of the line of best fit in raw units; describes relation between predictor and criterion variable (ie: a 1 unit increase in x is associated with an increase of b in y) controlling for other predictors

Q

p value

A

p=likelihood that we obtained this result by chance (the results are not real- its simply luck/chance that we got this result; interpreted by multiplying it by 100%

Q

Memetic View

A

A meme is similar to a gene

Although cultural evolution happens quickly, it happens in similar ways as biological evolution

Meme is a “unit of cultural transmission” which propagates itself “by imitation”

A meme may be of any size, randing from a single word to a complex behavioral pattern

Q

Memes (process of cultural evolution) evolve in similar process as those involved in genetic evolution IN 3 WAYS:

2)variation
3)selection

Q

1)Replication:

A

A meme is copied through imitation
Imitation allows for vertical, horizontal, and oblique transmission, making meme replication very rapid
Memes are high in fecundity-spreads rapidly

Q

2)Variation

A

When a meme undergoes mutation (ie modification through misinterpretation) or recombination (2 or more memes combined)

New memes are produced in this manner, leading to “innovations”

Both mutation and recombination are common in transmission of memes, so memes are high in fidelity(copied exactly) at first, then low over time (when people understand the meme and use it in their way)

Q

3)Selection

A

When different memes have different rates of retention in memory

Those that are retained more likely to be spread to others

Memes more likely to be retained if they are associated with:

~survival/reproductive advantage
~Economic advantage
~Positive affect (ie stay happy, stay positive)
~Fear
~Easy communicability

Q

Socialization experience
28 weeks (around 7 months)

A

fetus starts reliable response to acoustic stimulation (fetus has developed good acoustic system to be able to respond to it)

Q

Background noise (noise floor):

A

Fetus is surrounded by background noise including maternal respiration, maternal organ activity (respiration and intestinal), maternal physical activity

Other factors obscuring perception of external sounds:
~Tissues and fluids surrounding fetal head
~Route of sound transmission into fetal inner ear
~Sensitivity of fetal hearing mechanisms

Q

In order for intelligible speech to reach the fetus

A

it must surpass background noise and other factors obscuring speech (similar to being underwater)

Q

sleep=biological necessity
but..

A

But parameters of sleep not universal

Japanese babies sleep the least

Q

Differing views on infant co sleeping/sleeping alone

A

European children are more likely to sleep alone, asians children more likely to sleep in parents room or the parents bed

Some say co sleeping with parents is better promotes infant and parent bonding and easier to breastfeeding

Some people say cosleeping with baby is just as dangerous

Q

Sudden infant death syndrome (SIDS)

Evidence for dangers of co-sleeping:

A

Majority of sudden and unexpected infant deaths during sleep occurred outside of crib

Bed sharing associated with 5 times higher likelihood of SIDS

Co sleeping may be associated with thermal stress (infants are bad at regulating body temp, they have too much body heat), airway obstruction, or rebreathing of parental expired air

17
Q

Evidence against the dangers of co-sleeping:

A

As co sleeping has increased significantly over time, SIDS death in the parental bed have significantly decreased

Risk factor are not causes - association of co sleeping and SIDS most commonly found in conjunction with other factors

Cultures that do more co sleeping actually have fewer SIDS cases than cultures that do less co sleeping

The percentage of cultures that have more bed sharing have the lowest SIDS rate

18
Q

Recommendations for co sleeping:

A

No smoking, alcohol, or drug use around the baby in bed or for adults before going to bed

Babies should be placed on their backs

Mattress should be stiff, bed sheets should be tight, beds should not have cracks or crevices

Babies should not be able to fall into crevices, get stuck in mattress, get rolled in sheets

Avoid couches. Don’t let them sleep on couches.

19
Q

Baumrind broke down parenting into two primary dimensions:

A

responsiveness and demandingness

20
Q

Responsiveness (baumrind)

A

degree of warmth, support, and acceptance vs parental rejection and non responsiveness

21
Q

Baumrind’s typology:

A

Authoritative: High demand and high responsiveness
Child centered, high expectations, focused on child’s emotional regulation

Authoritarian: high demand and low responsiveness: high demands, strict rules, little open dialogue

Permissive: low demand, high response: few rules, limits, and controle

Rejecting-neglecting: low response, low demand: disengaged, not supportive, no limits or monitoring, focused on own needs

22
Q

Demandingness:

A

degree to which parents are controlling and demanding

23
Q

Western research consistently arrives at one finding

A

authoritative perceived parental warmth and acceptance, autonomy, self-reliance, better school achievement

24
Q

Non-western parenting styles

A

Typology does not take into account parenting styles that exist in other cultures

25
Q

Jiao xun (chinese)

A

parenting style component that focuses on training child to be good members of society at significant costs to oneself

26
Q

Authoritarian parenting style effects across culture:

A

Instills fear from European American children

Trains assertiveness in african american children

Bad for academics for european american children, not for other ethnic minority children

27
Q

Authoritative
effects across cultures

A

Good for academics for european american children, no such relation for other ethnic minority children

28
Q

Further complications: parents with different parenting styles

A

Hispanic fathers often less responsive than hispanic mothers

Chinese fathers often less responsive than chinese mothers (some reversal over time)

29
Q

Noun bias

A

children’s tendency to think more about, and in terms of, nouns relative to other types of words (verbs)

30
Q

is noun bias universal?

A

childrens emphasis on nouns is the same everywhere IS WRONG

Instead, yes children do emphasis more on nouns but the emphasis varies by culture

31
Q

Culturally variability in noun bias

A

noun bias is biased towards language that are noun-biased

Ie: in english the object is in more salient position (a more noun biased language), in korean the verb is in a salient position
