-
Microsystems
- events that happen on a daily basis
- made up of relationships between the person and his/her environment in a particular setting
- peers, teachers in school
- parent/child interactions
-
CNS (Central Nervous System)
-
measuring brain waves to see what parts of the infants
brain is aroused when experiencing certain things
-
ANS (Autonomic Nervous System)
-
measuring heart rate and respiration; helps understand
when the infant is feeling stressed
-
Hormonal Activity
what hormones are present by taking swab of saliva
-
Paired Preference Technique
- what does baby look at longer? Two stimuli are
- presented next to one another
-
response-contingent procedure
-
teach baby a contingency and see what they do
ex. sucking a certain way
-
-
using the infants’ tendency to get bored and lose interest on the same thing to understand whether or not they notice when a new stimulus is presented
-
Cross sectional
the research selects a different group of children at each age period of interest. give a sense of age change in development without having to wait for the children to grow up
-
Longitudinal research
researchers follow same group of childrenover time
-
DZ:
Faternal or Dizygotic twins
if two different zygotes are fertilized
-
MZ:
Identical or Monozygotic twins
one zygote is fertilize
-
Artificial insemination
sperm from father is directly placed in mothers fallopian tubes
-
In Vitro Fertilization (IVF)
ova is removed and joinedwith sperm. After fertilization and zygote has made a few cell divisions (embryo) it is implanted in mother’s uterus
-
Sperm microinjection
sperm is directly injected directly into the ovum
-
Embryo Cryopreservation
many oba are removed from the mother and frozen
-
-
vitro zygote from mother and father can be implanted in the uterus of another women then carries until birth
-
-
becomes part of the digestive, urinary, and respiratory system
-
Ectoderm
becomes the central nervous system and brain, sense organs, skin, nails, hair, and teeth
-
Mesoderm-
will become the muscles, bones, circulatory system, and reproductive system
-
Germinal stage
0-2 weeks
Fertilized ovum called a zygote
-
Embryonic stage
- 2-8 weeks
- Developing child is an embryo
Major organs and body parts develop
Most critical when environmental damage most likely to occur
-
Fetal stage
8 weeks to birth
Developing child is a fetus
Elaboration of existing organs and structures
Brain develops rapidly
-
Amniocentisis
withdraw amniotic fluid with needle. Fetal cells can be tested for abnormalities
Occurs 16-17 weeks
Can result in miscarriage
-
Chorionic Villus Sampling (CVS)
assess genetic material in fetal cells
Can be done in 1st trimester
Go up through vagina and into uterus
Slight risk of miscarriage
Tests for genetic chromosomal abnormalities
