Test 2 Flashcards
Human development
Scientific studying of people as they develop over their lifetimes
Longitudinal design
10-50 years High-quality data Hard to replicate Expensive Attrition (participants might quit)
Cross-sectional design
Study multiple age groups simultaneously
Studies cognitive development
Assumes all generations develop the same
Cohort effect
Related to cross-sectional design. Something happens to one age group that didn’t to the others, like COVID-19 or the Cold War.
Nature (genetics)
Influence of genetic/biological characteristics on personality, physical traits, IQ, etc.
Nurture (genetics)
Influence if environment on personality, physical traits, IQ, etc.
Behavioral genetics
The study of nature vs. nurture
Studied best using identical twins separated at birth
Epigenetics
TBD
Genetics
Study of inherited traits
DNA
Molecule containing genetic material
Gene
Section of DNA with specific arrangement
Located on chromosomes
Dominant/Recessive Genes
TBD
Monozygotic twins
One zygote splits into separate embryos
Identical DNA
Dizygotic twins
Two eggs fertilized, fraternal twins
Siamese twins
Conjoined twins
First 2 weeks of pregnancy
Germinal Period
2-8 weeks of pregnancy
Embryonic Period
8+ weeks of pregnancy
Fetal
“Critical period” of pregnancy
A stage of development critical for development of the heart, lung, brain, etc.
Teratogen
Anything that can harm an unborn child (like drugs)
Zika virus
Mosquito bite virus
If at a certain point, can cause baby to have a health issue where it has a tiny head and cognitive issues
Microcephaly
Result of zika virus in unborn child
Causes tiny head and cognitive issues
Very rare
Infants’ 5 reflexes
Sucking
Grasping/pulling
Rooting
Stepping (wiggling their feet while laying down)
Moro (startle reflex, baby sort of flails around)
Infants’ senses
All but vision are well-developed at birth
Growth and fine motor skills develop quickly throughout infancy and childhood
Infant/child motor milestones
Baby raises its head Baby rolls over Baby can sit if propped up Baby can sit on its own Baby can crawl/walk
Schema (cognitive development)
Mental concepts formed through experiences with objects/people (i.e., child’s concept of “dog” or “soldier”)
Psychologist who studied schemas (cognitive development)
Piaget
What did Piaget study?
He studied development of schemas.
He used longitudinal and cross-sectional studies.
He used his association with a school district to find children to study.
His experiments resulted in the Cognitive Development Stage Theory.
Stage 1 of Cognitive Development Stage Theory
Sensorimotor stage
Infant exclusively uses senses and motor skills to interact with environment
Object permanence
Acquired at end of Stage 1 of CDST
Babies understand objects/people exist even while not in sight
