PSYC 140 FINAL EXAM 2026 FINAL REVIEW
QUESTIONS ANSWERS BUNDLED PRACTICE
COLLECTION
◉ Why can many teratogens affect a child's cognitive development.
Answer: Because the baby's brain is most vulnerable after
organogenesis and throughout pregancy because it is under
continual development
◉ Stages of Childbirth.
Answer: 1. Dilation and effacement of the cervix (early labor + active
labor)
2. Delivery of the baby
3. Delivery of the placenta
◉ Early Labor Phase.
Answer: 1st phase in stage 1 of labor, lasts 8-12 hours, in which
contractions are usually not painful and last about 30-45 seconds
with 5 to 30 minutes of rest in between. The cervix begins to thin
out and dilate.
◉ Active Labor Phase.
,Answer: 2nd stage in stage 1 of labor, lasts 3-5 hours. Contractions
last about 45-60 seconds with 3-5 minutes of rest in between. Cervix
continues to dilate from 3cm to 7cm.
◉ stage 2 of labor.
Answer: begins after the cervix is dilated completely (10cm) and
ends after the baby's delivery. May last from 20 min to 2 hours.
Strong urge to push and strong sense of pressure at the rectum.
◉ stage 3 of labor.
Answer: delivery of placenta, takes 5-10 minutes. mother may
experience shaking and shivering after the placenta delivery.
◉ 3 types of drugs used for labor and delivery.
Answer: Analgesics, Anesthesia, Oxytocics
◉ Analgesics.
Answer: relieve pain, include narcotics, barbiturates, and
tranquilizers (NSAIDS)
◉ Anesthesia.
Answer: blocks sensation of pain in a certain area of the body
(general anesthesia: block consciousness, epidural anesthesia:
regional block)
,◉ oxytocics.
Answer: synthetic hormones used to stimulate contractions for the
purpose of inducing labor
◉ postpartum period.
Answer: The period after childbirth when the mother adjusts, both
physically and psychologically, to the process of childbirth. This
period lasts for about six weeks or until her body has completed its
adjustment and returned to a near prepregnant state.
◉ What are disadvantages of the naturalistic study method?.
Answer: Researchers can only access the information that they
directly observe. The child may act differently in other settings or at
other times.
◉ What is a disadvantage of the correlational study design?.
Answer: Correlation does not equal causation; a correlational study
doesn't tell what actually caused any change.
◉ 3 types of prenatal testing.
Answer: ultrasound, amniocentesis, chorionic villus testing
◉ ultrasound.
, Answer: a prenatal test in which the echo from sound waves send
into the mother's abdomen is used to create an image of the baby
which can be used to show the position, gender, and age of the baby
along with some developmental defects. It's noninvasive and
generally safe, but it's recommended to have fewer than five during
a pregnancy.
◉ Amniocentesis.
Answer: Involves inserting a syringe into the uterus to retrieve a
sample of the amniotic fluid which contains proteins and shed cells
which can be tested for chromosomal and genetic abnormalities.
There is a slight risk of miscarriage.
◉ chorionic villus sampling (CVS).
Answer: Prenatal diagnostic technique that involves taking a sample
of tissue from the chorionic villi which grow on the placenta and
contain the same genectic makeup as the baby. This tissue can be
tested for genetic abnormalities. There is a higher risk of
miscarriage than in amniocentesis and a risk of causing a limb
deforminity in the baby.
◉ 3 periods of prenatal development.
Answer: germinal, embryonic, fetal
◉ germinal stage.
