Final Flashcards
(175 cards)
Nature Controversy
Our inborn biological characteristics based on the genes we inherit
Nurture Controversy
Our environmental factors - physical and social world around us
Continuity Controversy
same basic skills and behaviors throughout all ages, development is a gradual change in amount of skills and complexity of behaviors (same basic things growing and refining)
Discontinuity Controversy
Unique ways of thinking, and feeling - different across age groups
Active Controversy
Participants in influencing how others respond to them and what their environment is like (implicated in education)
Passive Controversy
Environment plays direct role in child’s development, they are influenced by their peers and experiences
Positive Correlation
As one variable increases, so does the other; as one variable decreases, so does the other (move in the same direction)
Negative Correlation
As one variable increases, the other decreases; as one variable decreases, the other increases (move in the opposite direction)
Characteristics of Experiments
- Researcher manipulates variable (independent variable)
- Researcher measures whether this manipulation influences other variables (measuring the dependent variable)
- Researcher attempts to control extraneous factors (confounding variables)
Longitudinal Design
Same group studied at different times (repeated at different ages)
Cross-Sectional Design
- Different groups studied at the same time
- Differences between the groups are assumed to be because of developmental changes
Chromosomes
structures in cells that contain genetic material
DNA
Substance chromosomes are made of
Genes
Segments of DNA that provide specific biochemical instructions
Dominant-Recessive Inheritance
The dominant allele affects the characteristics, while the recessive allele has no effect
Conception:
Union of male sperm and female ovum
Blastocyst
4th day after conception - hollow ball of 60-70 cells
Embryonic disc
cells that become organism
Trophoblast
protective covering around developing baby
Ectoderm
nervous system, skin
Mesoderm
muscles, circulatory system
Endoderm
digestive system, lungs, liver, pancreas, urinary system
Critical Period
there are times when certain things really need to go correctly for healthy development to happen, if something goes wrong, there can be a problem with development
Vernix
white cheese like substance that protects the skin
