Q

feagans, kipp, and blood (OM moms rated)

A

looked at OM in good/medium/poor quality daycares. 1-1.5 year olds
divided them into chronic OM groups and those unaffected
observed them with picture book readings, watched how often they went off task and gave mothers a questionnaire to rate their children’s ability to pay attention
mothers of chromic OM rated them as less attentive, when in reality kids in poorest daycare were.

Q

klaus and kennel (bonding at birth)

A

bonding happens right after birth. preemie babies hit milestones faster when allowed to bond with parents. lead to babies staying in the room, and family members being in the room. later found that bonding doesn’t matter.

Q

ecological approach (bronfenbrenner)

m/m/e/m/c

A

microsystem: you and your immediate surroundings (ex; your roommates)

mesosystem: when your microsys interact with each other (ex; your roomie picks up your hw from your study buddy)

exosystem: doesn’t directly contain you, but influences you (ex; parents’ workplace)

macrosystem: the values, ideals, and customs favored in a culture (ex; breastfeedings happens less in countries that sexualize breasts)

chronosystem: how your cohort impacts you (ex; millennials are dirt poor)

Q

three developmental study methods…

A

cross-sectional
longitudinal
sequential

25
Q

cross-sectional design

A

look at subjects at different ages at the same time

pros: quick, cheap, can see diff. behavior at diff. points of development

cons: no info about past, no info about individual development, no info about dev. process

26
Q

longitudinal design

A

same subjects assessed repeatedly

pros: can determine behavior stability, diff. in behavior at diff. points of development, impact of early events are obvious

cons: costly, subject loss, changes in people, inflexibility, test-retest effects

27
Q

sequential design

A

cross-sectional and longitudinal together

pros: flexible, can determine behavior’s stability, impact of early events is investigated, diff. in behav. seen at diff. points

cons: most costly, subject loss, rest/retest effect

28
Q

structured observation

A

structuring an environment so that a behavior you want to observe happens

29
Q

hamster toy study

A

kid put in room with awesome toys but told to watch a hamster while the researcher steps out. when the kid looks away the hamster goes down a chute, the researcher comes back and asks if the kid watched the hamster.
we see if kids lie or not!

30
Q

clinical vs. structured interviews

A

clinical: ask them questions, their responses guide your next questions. DIFFERENT

structured: everyone gets the same question regardless of answer

31
Q

case studies

A

observe a unique person with great detail to try and learn something

32
Q

genie’s case study

A

tied to bed until she died, but she didn’t so the mom took her to CPS but it was clear something was wrong, she was raised without socialization. learned a lot of words but lost them, inability to communicate

33
Q

david reimer

A

dick was accidentally chopped off as a baby so he got surgery and was raised as a girl. but he figured out that he wasn’t a girl, rejected ‘brenda’ and ultimately killed himself… he had a twin and they’d be studied on and off.

34
Q

ethical issues with developmental psych include…
d/c/ci/a

A

deception, children, cognitively impaired people, animals

can they consent?

35
Q

rights of research participants include…
pfh/ic/p/k/bt

A

protection from harm, informed consent, privacy, knowledge of results, beneficial treatments

36
Q

DNA, genes, and chromosomes

A

DNA is the essence of us
Genes are the bits of DNA found in a chromosome
Chromosomes store and transmit genetic information

37
Q

mitosis vs. meiosis

A

mitosis: 46 –> 46 and 46

meiosis: 46 –> 46 and 46 –> 23 and 23

38
Q

genotypes vs. phenotypes

A

g: the genes you have
p: the traits you display

ex; curly hair

39
Q

range of reaction

A

our genetics set the limits, and our environment determines where we fall along a spectrum

40
Q

canalized

A

environment is a canal, our genes are a ball that rolls through it. sometimes it’s a gutter and sometimes it’s messy

41
Q

strongly vs. weakly canalized traits

A

strong: the environment can’t push them around (ex; eye color)
weak: the environment can push them around a lot (ex; intelligence)

42
Q

human inherited conditions only require __ gene

A

one! kid has a 50% chance of getting it

ex; huntington’s and neurofibromatosis

43
Q

huntington’s disease:

A

degenerative brain disorder that presents in middle adulthood

44
Q

neurofibromatosis

A

benign tumors on the skin, like, A LOT of them

45
Q

homo vs. heterozygous
dominant vs. recessive

A

homo: genes received are identical
het: genes received are different
dom: genes that are expressed
rec: genes expressed if no doms are there

46
Q

recessive inherited conditions (4)
c/sc/pku/ts

A

require two lowercase to show! ex; cc

ex; cystic fibrosis (lungs fill with mucus), sickle cell anemia (resistant to malaria), PKU (is diet restricts phenylalanine, their brain won’t degenerate), tay-sachs (brain deterioration, dead by 3)

47
Q

human x-linked inherited conditions

A

conditions found specifically on the x-chromosome. can be silent in girls but will always show in boys.

ex; color blindness (most common is red/green), hemophilia (blood won’t clot), severe combined immune deficiency (no immune system)

48
Q

david and severe combined immune deficiency

A

put in a sterile room until he sadly died at 13

49
Q

imprinting

A

process by which genes are ‘branded’ by one parent or the other. essential for normal development and turn on and off during different times of life

ex; ligers that just keep growing since the fem lion gene doesn’t silence it via imprinting

50
Q

polygenic inheritance

A

multiple genes that work together and influence each other

ex; height

51
Q

chromosome conditions (4)

A

involve chromosomes and genes

ex; turner’s (missing a sex chromosome), klinefelter’s (get an extra sex chromosome), down syndrome, fragile x (genetic, x-chrom looks broken, 1/4000 guys and 1/8000 girls)

52
Q

fragile x

A

dominantly inherited ‘broken’ x-chromosome. bigger problem with guys. causes cognitive deficit and learning disability, as well as delayed speech development, and long faces. 15% also have autism

53
Q

down syndrome

A

extra chromosome (21), generally short and stocky build, flat faces, heart abnormalities, higher hernia risk, compromised immune system/susceptible to infection, IQ 35-70 but variable, 1/700

54
Q

the risk of all chromosomal conditions _____________ with age

A

increases

55
Q

when prenatally detective down syndrome, __% in US will terminate, but ___% in Iceland will

A

67, 100

56
Q

skotko (down syndrome happiness)

A

those with DS are positive about life and themselves. they love their families and their families love them, generally indicating a good quality of life, though family members between ages 9-11 feel embarrassed by their relations

57
Q

noninvasive genetic testing (3)
tq/f/u/c

A

triple/quad screen: bloodwork, 15-22 weeks, 1/x results

first trimester screen: ultrasound, bloodwork, increased neck thickness:down syndrome, 11-14 weeks

ultrasound: don’t overdo!

cell-free fetal DNA: blood sample after 10 weeks, can look for fetal cells in blood and diagnose down syndrome and other chromosomal defects

58
Q

invasive genetic testing
C/a/P/P

A

CVS: needle goes in, sucks up villae, analyzes chromosomes, early as 9 weeks, associated with higher termination but those who take it are at higher risk anyways

amniocentesis: same thing, but amniotic fluid, 11-12 weeks

PUBS: blood sample from fetus via umbilical cord, can administer Rx that way

PGD: harvest egg and sperm, incubate embryos outside of the body and they pick the one that isn’t infected
