PY. Ch.10 Flashcards
Development is
measured in three
main domains of
interest:
Biological or
Physical
Development,
Cognitive
Development, and
Socioemotional
Development.
The fertilization of the female egg by the male sperm
Conception
First stage of prenatal development, which begins with ovulation, conception, and implantation in the uterus (the first two weeks)
Germinal Period
What is the baby called in the Germinal Period?
Zygote
After implantation through the eighth week
Embryonic Period
What is the baby called in the Embryonic Period?
Embryo
*From eight weeks to birth
*Increased growth and “fine detailing”
Fetal Period
What is the baby called in the Fetal stage?
Fetus
How many and what months are critical during pregnancy?
The First Three Months
such as
alcohol and nicotine, are environmental agents that can cross the placental barrier and cause damage during prenatal development.
Teratogens
is a combination of birth defects from
maternal alcohol abuse.
Fetal Alcohol Syndrome (FAS)
use during pregnancy is most associated with premature birth, low birth weight infants, and fetal death. Smoking increases the risk in the offspring for reduced attention span and learning and behavioral problems.
Nicotine
Average American newborn is ?inches long and weighs ?pounds.
20 inches & 7½ lbs
Infants usually double their birth weight by the age of four months and nearly about what in a year?
triple their birth weight by the age of one year.
At birth, the brain weighs about 25% of its adult weight
* By 2 years, the brain is
75% of its adult weight
Period of psychological development between childhood and adulthood
Adolescence
Biological changes during adolescence that lead to an adult sized body and sexual maturity
Puberty
- Lasts for 2 to 3 years with Rapid increases in height, weight, and skeletal growth
- Changes in reproductive structures and sex characteristics
- Boys tend to benefit from early maturation while girls tend to benefit from late maturation
Growth spurt during Adolescence:
Cessation of menstruation
Decreased estrogen production
Does NOT cause mood swings, loss of
sexual interest, or depression but for
some there are some losses
Many report relief
Menopause (45-55)
Gradual decline in testosterone and
sperm production
Can reproduce into their 80s or 90s
May have weight gain, graying or loss
of hair, decreased sexual response
and muscle strength
Male climacteric
Peak physical performance typically occurs between
19 and 26
believed humans progress through four distinct stages of cognitive development
* Learning in 1 period enables progress to next
* Each marked by different abilities, ways of thinking
* Concept of cognitive disequilibrium
Piaget’s Cognitive Theory
you hide an object under a blanket and a child tries to find it. is an example of what operation?
Stage 1 Sensorimotor with development of object permanence
A child drawing people or objects from their own life but understanding they are only representations or playing pretend. is an example of what operation?
Stage 2 Preoperational symbolic thought with irreversibility, Egocentrism, Centration
Children understand logical reasoning is an example of what operation?
Concrete Operational
* Decentration, Reversibility, Conservation
If Kelly is taller than Ali and Ali is taller than Jo, who is the tallest? is an example of what operation?
Formal Operational
* Abstraction, Hypothetical thinking
