2025 LATEST UPDATE!!
Terms in this set (359) QUESTIONS VERIFIED ANSWERS
longitudinal study design following individuals over a long period of time
with multiple assessment points
cross-sectional study comparing different age groups at the same time
naturalistic observation research method in which one observes a subject
outside of a research setting
case study research method involving a direct observation of
a patient; interviewing in great detail
study/interview research method in which surveys administered
anonymously or asked in and interview format in-
person
correlational research research method of seeing how two variables
relate; looking at strength and direction of
relationship
,experiments research method in which you tightly control the
variables, setting, and participants which
manipulating one factor believed to have
influence.
Hawthorne effect A change in a subject's behavior caused simply by
the awareness of being studied
What are the five research methods - naturalistic observation
discussed in this module? - case study
- study/interview
- correlational research
- experiments
three types of prenatal diagnostic tests ultrasound, amniocentesis, and chorionic villus
sampling (CVA)
ultrasound prenatal diagnostic technique that uses high
frequency sounds to create an image of the baby
amniocentesis Prenatal diagnostic technique involving needle
puncture of the amniotic sac to withdraw amniotic
fluid for analysis; looks for chromosomal and
genetic abnormalities
chorionic villus sampling (CVS) Prenatal diagnostic technique in which a small
sample of the fetal portion of the placenta is
removed for analysis to detect certain genetic and
congenital defects in the fetus.
,what are the three types of genetic- passive, evocative, and active
environment interactions?
passive genotype-environment interaction parents provide genetic disposition and nurturing
context to foster certain qualities
evocative genotype-environment interaction parents provide genetic predisposition for a child
to evoke certain reactions in others that will
influence their development
active genotype-environment interaction parents provide genetic predisposition that results
in a child actively seeking out environmental
conditions that foster development of certain
qualities
three periods of neonatal development germinal, embryonic, and fetal
germinal period week 0-2
zygote created, attaches to uterus wall
embryonic period week 2-8
layers of cells form that later develop into organs
and systems
fetal period month 2-9
major growth and development
teratogens agents that interfere with natural growth and
produce a birth defect
which three variables determine a - gestational age
teratogen's effect? - amount of teratogen
, - susceptibility
When does organogenesis begin? Around week 3 through week 8
why is stress a teratogen? stress causes blood to be directed away from fetus
and towards mother's brain, limbs, heart. Cortisol
can cross placenta and increase fetal HR
why is cognitive development more brain develops all throughout pregnancy
susceptible?
what are the three phases of childbirth? - early & active labor
- delivery of baby
- delivery of the placenta
early labor and active labor - longest stage
- starts at onset of true labor
- ends when cervix completely dilated
- 30-45 sec contractions w 5-30 min between
- 45-60 sec contractions w 3-5 min between
- amniotic sac may rupture
delivery of baby - begins when cervix dilated
- 20 min-2 hrs
delivery of placenta - 5-10 min
- contractions again
- placenta separates from uterine wall
three drugs used in childbirth analgesia, anesthesia, oxytocics
Analgesia vs Anesthesia drugs that relieve pain; includes narcotics,
