Development
ans:> the process of change in an organism's
physical/social/emotional/cognitive state
Critical period
ans:> an optimal period shortly after birth when an organism's exposure
to certain stimuli or experiences produces proper development
Sensitive period
ans:> a point in development when organisms are particularly
responsive to specific stimuli and has behaviors that are more easily
modified, but it is less fixed and irreversible than a critical period; causes
learning depositions and affects learning development
ecological model of human development
ans:> individual, microsystem, mesosystem, exosystem, macrosystem,
chronosystem
evolutionary psychology
ans:> a field of psychology study focusing on adoption, reproduction,
and survival
evolutionary developmental psychology
ans:> an approach that uses evolutionary psychology to understand a
person's development
chromosomes
ans:> threadlike structures made of DNA molecules that contain the
genes
,DNA
ans:> a complex molecule containing the genetic information that makes
up the chromosomes
genes
ans:> short DNA segments that carry hereditary information; each
gene's activation depends on hormones/environment
mitosis
ans:> cell division in which the nucleus divides into identical nuclei
containing the same number of chromosomes (46); happens in the body
cells
meiosis
ans:> a type of cell division that results in four children cells each with
half the number of chromosomes of the parent cell (23), becoming
eggs/sperm; happens in the sex cells
crossing-over
ans:> the process where DNA is exchanged between chromosome pairs
in meiosis
independent assortment
ans:> the principle that each chromosomes pair splits independently of
other pairs in meiosis
adenine
ans:> a component of nucleic acids; the base that pairs with Thymine in
DNA
cytosine
ans:> a component of nucleic acids; the base that pairs with Guanine in
DNA
alleles
ans:> different versions of the same gene
dominant alleles
ans:> an allele whose trait always shows up in the organism when the
allele is present
recessive alleles
,ans:> alleles that show their effects only when both alleles are the same;
it is masked when there is a dominant alleles
co-dominant alleles
ans:> two different alleles at a locus are responsible for different
phenotypes, and both alleles affect the phenotype of the heterozygote
heterozygous
ans:> organism that inherits a gene with two different alleles
homozygous
ans:> organism that inherits a gene with two alleles of the same type
fertilization
ans:> when an egg and a sperm fuse into a zygote
germinal stage
ans:> 0-2 weeks: zygote; starts with egg being fertilized; ends when egg
implants in the uterus; generally unaffected by teratogens
zygote
ans:> the fertilized egg; it enters a 2-week period of rapid cell division
and develops into an embryo; has 23 paired chromosomes where each
parent gives half
embryonic stage
ans:> 2-8 weeks: embryo develops most important physiological
features; most vulnerable to teratogens
gestation
ans:> pregnancy; growth process from conception to birth
embryo
ans:> the developing human organism implanted on the uterus wall;
from about 2 weeks after fertilization
amniotic sac
ans:> a fluid-filled sac that cushions and protects a developing embryo
and fetus in the uterus
placenta
ans:> a disc-like structure in the uterus that nourishes and maintains the
fetus through the umbilical cord
, umbilical cord
ans:> a tube containing the blood vessels connecting the fetus and
placenta
cephalocaudal
ans:> how fetus development starts at the brain then downward to legs
proximal-distal
ans:> how fetus development starts at internal organs then outwards
miscarriage
ans:> spontaneous end of pregnancy before the baby can survive
outside
foetal period
ans:> 3 months - delivery: completing development of body structures &
systems; first body responses (e.g. thumb sucking)
foetus
ans:> developing organism during the foetus period
age of viability
ans:> the age (about 22 weeks after conception) at which a fetus may
survive outside the parent's uterus
teratogen
ans:> environmental agents, such as chemicals and viruses, that can
reach the embryo or fetus during prenatal development and cause harm;
more exposure can cause more harm
foetal alcohol syndrome (FAS)
ans:> a birth defect caused by alcohol abuse by the pregnant parent;
can cause facial deformities, restricted intelligence and an agitated
personality
risks of smoking during pregnancy
ans:> miscarriage, premature labour, birth defects, SIDS
risks of caffeine during pregnancy
ans:> miscarriage, underdevelopment, low birth weight
diethylstilbestrol (DES)
