Primary Reinforcers
Those things necessary for the survival of an organism. Ex: Food, shelter, sex

Things that become reinforcing through their association with a primary reinforcer. Ex: Money.

Positive Punishment
Adding an unpleasant stimulus to weaken a behavior. Ex: Spanking. 
Negative Punishment

The 3 Prenatal Periods
Germinal (days 1-14).Embryonic (3rd-8th week).Fetal (9th week- birth).
Germinal Period (days 1-14)
Zygote implants itself along uterine wall. 1/2 successful, 15% to 50% miscarriage.
Embryonic Period (3rd to 8th week)
Organogenesis (rapid organ development). Most susceptible to teratogens. Sexual differentiation.
Fetal Period (9th week- birth)
Proliferation, migration.Major muscular development.Ends in tremendous brain development. 
Negative environmental influences that can potentially harm or destroy developing organisms.
After how many weeks is the child normally born?
40 weeks (38 in uterus, 2 weeks post las menstrual period).Can live on its own at about 28...
What factors are involved in determining how much of an impact a teratogen will have?
Dosage & duration. Genetic make-up: susceptibility. 
For morning sickness. All or parts of limbs missing & many didn't survive. 
Miscarriages. Low birth weight. Mental retardation.Physical problems.Slow fetal growth.SIDS
FAS.Small. Facial deformities.Retardation.
Processing difficulties.Severe behavioral problems.
Rubella (German Measles)
Blind.Deaf. Heart problems.Brain problems.
Miscarriage.Blind. Deaf.Heart: circulation issues.Brain.
MR.Leukemia.Cancer.Mutations.Spontaneous abortions.
