Chapter 9 Flashcards
Defined as the pattern of continuity and change to human capabilities that occur throughout the course of life, involving growth and decline. Most development involves growth, although it also is concerned with decline.
Human Development
Three different levels of change.
- Physical processes
- Cognitive processes
- Socioemotional processes
Changes in an individual’s biological nature including genes inherited from parents, hormonal changes of puberty and menopause, brain changes throughout life, height, and weight, and motor skills.
Physical Processes
Changes in an individual’s thought, intelligence, and language.
Cognitive Processes
Changes in social relationships with other people, in emotions, and in personality.
Socioemotional Processes
Physical, cognitive, and socioemotional processes are what?
Inter-related and inter-dependent.
Refers to the biological changes that occur throughout life.
Maturation
Relates to different aspects of one’s physical, cognitive, and socioemotional characteristics.
Age
Is a variable that cannot be experimentally manipulated, studies on the relationship between age and other characteristics are by definition correlational in nature.
Age
Refers to an individual’s biological inheritance, especially their genes.
Nature
Refers to the person’s environment and social experiences.
Nurture
To the behaviorist, including ____ _ ______, all behavior is due to the environment.
John B Watson
(the individual’s genetic blueprint)-his or her actual genetic material.
Genotype
(the person’s observable characteristics). Shows the contributions of both nature (genetic heritage) and nurture (environment).
Phenotype
Phenotype is the outward expression of the
Genotype
We learned that the heritability of intelligence is approximately
75%
Therefore we can that ___ of intelligence is inherited and ___ is due to environmental influences.
75%
25%
The conclusion that development is the product of nature, nurture, and the
Complex interaction of the two.
The first stage in human development is the prenatal period beginning with
Conception and ending with the birth process
Occurs when a single sperm cell fertilizes the female’s ovum to produce a zygote.
Conception
A single cell with 23 chromosomes from the mother and 23 chromosomes from the father.
Zygote
What are the 3 periods that are divided into the development from zygote to fetus?
- Germinal Period
- Embryonic Period
- Fetal Period
(1-2 weeks) Begins with conception. Consisting of rapid cell growth and finally attaching itself to the wall of the uterus.
Germinal Period
(3-8 weeks) Cell differentiation intensifies and around the 8th week organs begin to develop. By the end of the 3rd week the neural tube starts to take shape. By the end the ________ ______, the heart begins to beat, the arms and legs become more differentiated, the face starts to form and the intestinal track appears.
Embryonic Period
