Development Flashcards
Nature versus nurture
Genetic, development is innate(DNA)
Or
environmental factors (parents, friends, fam, society)
Or both
Continuity v.s. discontinuity
Development as a seamless process (infancy, childhood, adolescent, adulthood) rising up
Or
A sequence of distinct and separate stages
(Infancy, childhood, adolescent, adulthood) stairs
Stability vs change
From birth do we have core personality traits that endure throughout development
Or
Change as a product of development throughout life
Cross-sectional
Different populations at the same time
Ex. Studying substance use habits of 9, 10, 11, 12 graders simultaneously
Cohort effect
People who are approximately the same age and share a cultural experience
Limits ability to do a comparison study
Ex. Studying 9th in substance is difficult to compare to 12th graders because culture and perspective
Longitudinal
Same population over a period of time and how they evolve
Ex. Studied ninth graders in substance habits and followed through high school
Critical period
Younger you are, the more critical the impact
If development not supported, might inhabit or prevent later development
Ex. Three month old ->no food for three days they die VS no food for three days extremely hungry
Sensitive period
If development not supported, might render later development more difficult
Ex. Can’t teach an old dog new tricks
Prenatal development
Fertilization to birth
Conception :union of sperm and ovum
Zygote development
Embryonic period
Fetal period
Age of viability
Zygote development
Cell differentiation
Muscles?
neurons?
blood?
Embryonic period
2 weeks to 2 months
Organ development begins
Cell differentiation
Fetal period
9 week to birth
Age of viability
Integration of organ systems
And teratogens
Age of viability
Point at which a premature baby has a 50% chance of surviving outside the room
Teratogens
Toxic substances
Can cause birth defects or even terminate pregnancy
Psychoactive drugs
infectious disease
environmental toxins
Psychoactive drugs
Alcohol: fetal alcohol syndrome(FAS)
Cocaine: “unattached” syndrome (can’t emotionally bonded with anyone;angry)
Infectious diseases
Measles
chickenpox
HIV/AIDS
Environmental toxins
Flint river= lead & unpurified water
Neonatal development
Birth to 1 month Plasticity Optimum Survival Reflexs Habituation Language/ motor development
Optimum plasticity
Development of nervous system; brain cells & wires itself
Myelination
Synaptogenesis
Pruning
Lateralization
Reflex expression
Survival instincts of a newborn babies
Ex
Rooting: moving head when cheek gets touched; searching for a nipple
sucking
swallowing
grasping: closing hand tightly when palm is stimulated
Moro (startle): arching back, flinging arms outward when startled by a loud noise
Habituation
Stimulus desensitization and discrimination INDICATES REMEMBERING/ LEARNING
Childhood development
Characterized by dynamic increase in neural networking and corresponding cognitive development
Adolescence
A time of significant physiological change/ growth
Transitional period beginning with puberty
fertility
Development indicating puberty
Primary sex characteristics
Secondary sex characteristics
Menarche
Primary sex characteristics
Reproductive organs
Ovaries
Testes
Corresponding sex organs
