Exam #1 Flashcards
lifespan perspective
no age period dominates, the whole lifespan, how we change has both gains and losses
4 domains of development
physical, cognitive, social, emotional
Biologic
genetics, nervous system, endocrine system
cognitive
“faulty thinking,” changing thinking
behaviorism
measure behavior, changing the maladaptive behaviors
B.F. Skinner
Social Learning Theory
“Monkey see, monkey do,” modeling (specifically in early childhood)
Psychosexual Theory
Freud (psychoanalysis), 4 stage theory, unconscious drives (sex/aggression), early childhood experiences
psychosocial
Erik Erikson
8 Stage Theory
developmental “task” in each stage
Multi-cultural
traditions beliefs of culture
Evolutionary
role theory
men- protect and provide, maximize reproductive potential
women- find 1 dependable mate, caregiver
objective
from the outside looking in, no opinion, black and white
subjective
from inside, uses opinion, bias
longitudinal design
across time with less people
cross-sectional
taking one section with more people at one point in time
random sample
wide variety and equal chance of being selected
generalization of data
not usually correct but we tend to make generalizations
advantages of surveys
results generalize well, quick, easy, and inexpensive, massive amount of data, cross-sectional design
4 main types of research
surveys, correlational research experiments, and case-studies
disadvantages of surveys
data isn’t always truthful
case-study
an in-depth look into 1 or small group of people (family)
longitudinal results
advantages of a case study
rich and interesting information
disadvantages of a case study
data is subjective, results do not generalize well, and longitudinal design
correlational research
determines if 2 variables are related to one another and if so how strongly they are related (not proving just relation)
variable A increases variable B increases
+ direct relationship
variable A increases variable B decreases
- inverse relationship
correlational research
a number that indicates the strength of the relationship (between -1 to 1)
the closer the number is to 0
the weaker the relationship
negative means
inverse
the coefficient is a decimal
99% of the time
correlational coefficient between school uniforms and aggression
-0.45
correlational coefficient between laptops in class and GPA
+0.16
correlational coefficient between growing up with an alcoholic and becoming an alcoholic
+0.60
Experimental design aspects
- independent variable
- dependent variable
- experimental group
- control group
nature effects
genetics, heredity, biology
inherited traits
eye and hair color, height, facial features, intelligence, personality, temperament, metabolic rate
determined at conception
twin studies
provides the opportunity to measure effects of the environment
fraternal twins
2 eggs fertilized by 2 sperm
2 genetically different people
identical twins
1 egg fertilized by 1 sperm
fertilized egg splits into 2 identical people
environmental effects
family of origin (SES, religion, cultural values, communication style, modeling)
education (public, private, homeschool)
where you grew up (inner city, suburban, small city, rural)
egg
largest cell in human body, approximately 450, 1 per month for 40 years, reproductive potential is finite, viability of egg is 24 hours
sperm
produced continuously throughout life, 525 billion in a lifetime, viability of sperm= up to 5 days in reproductive tract, reproductive potential is limitless
release 1 egg typically every
28 days
day ovulation occurs
14
peak fertility
days 11-17 of menstrual cycle
where fertilization takes place
Fallopian tube
gestational period
40 weeks
period of the zygote
conception- week 2
massive and rapid cell division
what day does the zygote implant into the uterine wall
day 10
what is the embryonic period referred to as
the critical period
what weeks are the embryonic period
week 3-8
main events of embryonic period
often taking place out of mothers awareness
placenta develops (nutrients/hormones)
umbilical cord develops (oxygen and blood supply)
organ systems develop (all 8)
