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)
Refers to the elementary school years
middle and late childhood (6-11)
Accelerated mental skill development and an increased ability to talk about experiences, thoughts, & feelings are the key cognitive development during the time.
middle and late childhood (6-11)
Increase focus on friends 7 being accepted in a peer group.
middle and late childhood (6-11)
Is the development period of transition from childhood to adulthood.
adolescence (11-20)
It begins with puberty, a time of rapid growth & sexual development.
adolescence (11-20)
They develop the ability to understand abstract ideas, develop moral philosophies , & establish & maintain satisfying relationships.
adolescence (11-20)
They develop the ability to understand abstract ideas, develop moral philosophies , & establish & maintain satisfying relationships.
adolescence (11-20)
Is the time where individuals establish personal & economic independence

Choices concerning marriage & family as well as career decisions are often made during this stage.
early adulthood (20-40)
The period where adults develop a genuine concern for the welfare of future generations
middle adulthood (40-60)
They contribute to the world through family and work.
middle adulthood (40-60)
What are the 7 major task listed havighurst
- Physiological adjustment
- occupational satisfaction
- looking after aging parents
- effective guidance of teams
- socio-civic achievement
- strong matrimonial relationship
- leisure activity
A time of adjustment to decreasing strength & health, life review, retirement, & adjustment to new social roles.
late adulthood (60s onwards)
what are the aspects of development
- Anatomical
- Physiological
- Behavioral
what are the types of change in development
- change in size
- change in proportion
- disappearance of old features
- acquisition of new features
