3 Human Growth and Development Flashcards
is the scientific study of how people change and stay the same over time
Human Development
What are change
- Quantitative change
- Qualitative change
refers to variation in number, amount, or size
quantitative change
refers to a shift in kind, structure, or organization
qualitative change
what are the stages in prenatal period
- Germinal Stage
- Embryonic Stage
- Fetal Stage
Refers to the 2-week period following conception.
germinal stage
Extends from the second to the eighth week after conception
embryonic stage
occurs when a single sperm cell from the male penetrates the female’s ovum (egg)
conception or fertilization
Begins two months after conception & lasts until birth.
fetal stage
- There is a developing organism which is known as fetus.
fetal stage
Cells are divide & begin to differentiate into bone, muscles & body organs
embryonic stage
what are the chromosomal abnormalities
- turner
- down syndrome
- fragile x
- klinefelter
what are the prenatal diagnostic tests
- fetal MRI
- Ultrasound Sonography
magnetic resonance imaging designed to diagnose fetal malformations
fetal MRI
high-frequency sound waves used to create a visual representation of fetus’s inner structures
Ultrasound Sonography
The life-span approach to development conceives the human life cycle to consist of roughly eight stages
Development throughout the life span
what are the development throughout the life span
- prenatal period
- infancy
- early childhood (2-6)
- middle and late childhood (6-11)
- adolescence (11-20)
- early adulthood (20s-40s)
- middle adulthood (40s-60s)
- late adulthood (60s onwards)
Is the time from conception to birth
prenatal period
A single-celled zygote develops in a series of stages into a full0term baby complete with brain & behavioral capabilities
prenatal period
Lasts from birth until approximately the age of 2.
infancy
A great deal of initial learning, provided through environmental cues like parents’ behavior, occurs.
infancy
Basic skills such as crying, nursing, co- ordination, & the ability to represent mages & objects with words, are mastered during this period
infancy
Is a time of tremendous growth across all areas of development
early childhood (2-6)
The primary development task of this stage is skill development
early childhood (2-6)
