Q

Is culture unique to humans?

A

no -> if we define culture as information acquired through social learning

other species show cultural learning: monkeys, dolphines, killer whales, pigeons, bird species (calling strategies), octopus

Q

What is characteristic of cultural learning in humans?

A

it is faster (even upon single exposure) and imitation targeted
prestige bias = when we learn cultural skills, we pick the best available example to learn from

Q

What are differences between chimp and child learning?

A

learning how to operate puzzle box to obtain a treat
all imitate the researcher’s behavior

however, when second box is introduced -> see-through -> shows that not all researcher’s steps are necessary to obtain reward

chimps skip unnecessary steps to obtain reward

children are predisposed to copy all experimenter’s steps

Q

emulative learning

A

type of learning prominent in chimps
main focus on the outcome
more effective, less precise

accumulation of information is not as good as in the case of imitative learning (due to lower precision)

Q

What are evolutionary advantages of bigger brain?

A

better functioning in groups (better at creating and navigating social hierarchies)

social brain hypothesis → neocortex ration: neocortex is larger compared to sub-cortical parts = most social processes happen at neocortex

Q

What are two ways of explaining cultural variation?

A

evoked culture = all people have biologically based repertoire of behaviors that are accessible to them and these behaviors are engaged for appriopriate situations

transmitted culture = cultural norms learned from other individuals

23
Q

what are examples of evoked culture?

A

with higher parasite prevalence, there is stronger value put on physical attractiveness (singal of health) and conformity (stricter social norms for food preparation)

24
Q

what are examples of transmitted culture?

A

watching neighbor planting wheat seeds and then planting wheat seeds

25
Q

Is distinction between evoked and transmitted culture clear-cut?

A

No
particular behavioral script might be activated by specific situational variable → but if that behavioral pattern becomes a norm this norm might be learned by wider range of people (becoming transmitted)

26
Q

what accounts for more cultural variance?

A

transmitted culture!

27
Q

Which cultural ideas spread?

A

1) useful
2) communicable
3) minimally counterintuitive
4) emotional

28
Q

How do cultures change?

A

1) globalization (high homogenity on global level, but on local level there is GLOCALIZATION - adaptation of certain products to the practices of more restricted regions)

2) rise of individualism (due to isolating leisure, work commitments, more secularity, underlying one’s uniqueness)

3) Flynn effect = increase in IQ (environment getting more stimulating and complex)

29
Q

How to cultures persist?

A

cultural innovations are constrained by pre-existing structures!

Africa -> slave trades
regions with severe slavery trades, were associated with lower trust -> now, they experience lower economical development

also pluralistic ignorance -> even if people individually believe in sth, they may not express is due to cultural norms/beliefs (such as ideas about prohibition)

30
Q

When do we acquire culture?

A

idea of sensitive period in development = when learning of culture is easier and faster!

31
Q

How does distribution of sensitive period in human development looks like?

A

at birth -> developing sensory skills
later -> motor/language learning
even later -> higher cognitions

32
Q

What is treated as proxy of culture acquisition?

A

language acquisition

33
Q

What is critical period for language acquisition? studies

A

1) discrimination and categorization of phonemes
young infants can distinguish between phonemes in every language; this ability disappears when they are 10-12 months old

2) accent + shibboleths
* only youngest children in migrant family learns the language accent-free

3) fMRI study in bilinguals
activity in Broca area = of a person who learned English and Turkish at the same time - overlap when person speaks either of the languages

4) feral children -> brain seems to be plastic within 2 years of age; after this time it is hard to acquire language skills

34
Q

What are shibboleths?

A

anycustomor tradition, usually a choice of phrasing or single word, that distinguishes one group of people from another

35
Q

acculturation

A

related to learning second language

36
Q

Research of Minoura (1992)

A

acculturation of Japanese immigrant children in USA

highest type of acculuration = youngest children ( 9 years old or less)

so age of entry is important for acquisition of new culture

HOWEVER, alternative explanation would be that children who are more exposed to culture, identify with it more

37
Q

Cheung, Chudek and Heine (2011)

A

acculturation of Chinese immigrant children in Canada

not amount of exposure, but age of entry before the end of sensitive period predicts identification with 2nd culture

0-15 -> sensitive period -> the longer they spend in culture, the more they identified with it

31-50 -> tendency shifts -> the longer they spend in culture, the worse their acculturation was

38
Q

developmental niche theory

A

theoretical framework for understanding and analyzing how culture shapes child development

1) physical + social setting = what affordances the physical space provides (nutrition, climate)

2) customs and practices of child rearing

3) caretaker’s psychology -> parental ethnotheories (beliefs about child development and parenting)

39
Q

How cultural differences shape how kids develop motor skills?

A

African children acquire motor skills much faster -> because they are constantly carried (upright posture), sleep on tummy, get massages etc.

40
Q

how much space does the child need? how much physical vs face to face contact?

A

varies between cultures
- Cameronian children - more bodily contact

  • German and Greek children - more face-to-face contact
    -> faster recognition of self in the mirror -> mother treated as seperate being (more attuned to baby cry - suggesting turns in conversations)
41
Q

co-sleeping

A

idea that children should be sleeping with mother (some cultures normalize that mother should always be with a child, whereas in other cultures it is postulated that children should sleep alone)

42
Q

study about co-sleeping in India vs USA parents

A

Americans prefered when parents slept in seperate room

Indian parents didn’t show any preference

43
Q

What are cultural values endorsed by both Indian and USA parents?

A

incest avoidance = endorsed by both Indian and USA cultures = not likely to put children of the same ages and different genders together

44
Q

What are cultural values endorsed by Indian parents?

A
  • protection of vulnerable - youngest kid should sleep together with couple
  • female chastity anxiety - protecting virginity of youngest daughter
  • respect for hierarchy - adolescent boys dont have to sleep with their parents or young children
45
Q

What are cultural values endorsed by American parents?

A
  • sacred couple - parents should sleep together, without kids
  • autonomy ideal - children can sleep in seperate rooms, not with their parents to learn self-reliance
46
Q

what are two axis of parenting style?

A
  • how much do you demand from your child?
  • how much do you respond to your child?
47
Q

what are 4 types of parenting styles?

A

1) permissive = high responsiveness + low demand

3) authoritative -> high responsiveness + high demand

3) uninvolved -> low responsiveness + low demand

4) authoritarian -> low responsiveness + high demand

48
Q

What are differences in parenting style in the West vs East?

A

West -> authoritative parenting style -> focus on autonomy and self-reliance

East -> authoritarian parenting style -> focus on hierarchy and training the child

49
Q

What is important to consider about authoritarian parenting style in East Asia?

A

from Western perspective: lower perceived parental warmth, but excellent academic performance; very cohesive family but kids seem to be less happy

however, in East Asia emotional expresiveness is different

1) they are different parental approaches depending on stage of development (indulgence of toddlers)

2) warmth + responsiceness can be communicated in different ways

3) authoritarian category seems to exclude training aspect

50
Q

jiao xun

A

training
adherence to socially desirable behaviors, being role model

51
Q

What are 3 types of attachment styles?

A

1) secure -> reacts positively to mother return -> curious of the environment

2) avoidant -> reacts negatively to mother return -> offended and avoids contanct

3) ambivalent -> reacts negatively to mother return -> crying, cannot calm down

52
Q

different findings in attachment styles in different cultures

A

1) behaviors of mothers and children vary in Strange Situation = procedure might not have the same meaning everywhere

2) although, secure attachment is most often observed, other attachment styles are also identified regularly (Germany = avoidant style most prominent - early independence; Israel = ambivalent style - chldren grow up in communal environments and don’t develop exclusive attachment to their parents)

3) not all 3 attachment styles are found everywhere

Japanese/Dogon children “lack” avoidant attachment style

53
Q

noun bias

A
  • cultural variation in noun bias (prevalence of nouns relative to verbs in young children’s vocabulary)
  • noun bias prevalent in West (North America)
  • absent in East Asia → more verbs than nouns
54
Q

why noun bias is more prevalent in North America?

A

2 explanations proposed

1) linguistic -> 1. nouns or verbs may appear on salient positions depending on language/ (pro) nouns are dropped in some languages
- in English syntax → nouns at the end of sentence
- in East Asian languages → verbs at the end of sentence
2. cultural ⇒ children learn to communicate about objects differently across cultures
- West → object-focused communication → objects isolated from context = analytic reasoning
- East → emphasis on relations between objects → action focused communication = holistic reasoning

55
Q

article - psychological differences explained by rice vs wheat agriculture in cHINA

A

rice theory

rice = interdependent -> rice paddies with standing water -> farmers need to cooperate

wheat = independent -> easy to grow, doesn’t need irrigation system -> no need for cooperation
