test prep Flashcards
Understand the different domains of development
Pysical: the way the brain body and senses grow
Motor:the way a person develops control of their body (gross/fine)
social: the way somone develops relationships with others and understands their behaviour
emotional:The way a person experiences their emotions and understands others
cognitive: how a person thinks resons explores and undrstands the world
What is the theory of dynamic systems
All the domains interact with one another and impact our development our development also impacts them
How do the domains of development and the dynamic system theory affect a specific developmental mileston
(like learning to walk, learning to talk, etc
ex. learning to talk
Physical/motor: must have the strength and cordination to form words with toung or hands
vocal cords must be develped
fine motor skills must be developed
Impact? A person can comunicate wants or needs
Emotional/social: must have the social skills to talk with other and must have scial interactions in order to learn.
also must regulate emotions.
Impact? Can comunicate how they feel
Cognitive: Must be able to proccess vocabulary and learn words.
Enviromental: familly setting- does this person have people around them to speak with.
are these people emotionaly regulated
Whats the difference between the three stages of labour & delivery and identify the stage if given an example
Dilation and effacement (labour)
birth (Delivery)
Expulsion of plecental (afterbirth)
what scores high vs. low points on the APGAR scoring system, and why is it used
Activity
pulse over 100 bpm
grimace propt response to stimulation
appearance pink
respiration cry
0-2
find out if they need imidiate care
What is the differences between the three trimesters and what is occurring in each trimeste?
1st trimester: morning sickness
first 12 weeks
no emotional attachment
hormon flux
high risk for miscarage
2ed trimester:
baby showers
showing
The quickening: you can feel the baby
can find out sex of baby
13 weeks to 27
3ed trimester
- anexiety
- sore
- tired
- braxon hicks contaptions
- 28 to 40
Whats the difference between the embryonic, germinal, and fetal stages, when they occur, and what are the main things happening or developing in each stage
Germinal:
Zygot: fertilized egg- traveles dow fallopian tube
blastocyst: embeds in uterine wall- placenta forms around it (implantation)
timeline? 1-2 weeks
Embryonic:
embryo
timeline 3-8 weeks
formation of endoderm (nternal linings of the body (organs)) mesoderm (organ systems) and ectoderm (outermost skin layer- and nerves)
3= heart starts beating
4= neurons
fetal:
9-38
4 months = can feel
6 months hear
7 = see
9 months fat deposits
main organ growing is brain
earliest viable age? 22-38 weeks
What are the basics of fertilization
Must be ovulating- egg enters fallopian tube
Egg is ferilized 24 h after ovulation
mix chromosomes information
egg devides
zygot traveles through fallopian tube
day 4 enters uterus
blastcyst impanted into uterine wall
What is epigenetics?
Epigenetics is the study of how your behaviors and environment can cause changes that affect the way your genes work.
What is niche picking
We are more likely to seek out an envirmnt that better matches our heriditary. This strengthens genetic expression.
What’s the difference between Principle 1 and Principle 2
Principle 1
our nature influences nurture
the way we are influences how the world treats us
ex. temperment
Principle 2
How we are nurtured influences the expression of our nature.
The way we are treated influences how our genes are expressed
ex. hight and nutrition
Given an example of a twin study, be able to discern if a trait is more likely to be inherited (nature) or due to the child’s environment (nurture
ex. If we were to interview 50 indetical twins who were adopted into two different families on weather or not they like pinaple on pizza.
if both twins like pinaple the its heritable (nature)
If not its enviromental (nature)
what is construct validity and what is concurrent validity are
Construct validity: Does the test measure the concept that it’s intended to measure?
Content validity: Is the test fully representative of what it aims to measure?
What are observation, behavioural tasks, self-report, and biophysio data, and how can you tell the difference between them
Given an example of a research study, identify if the researcher used a correlational, experimental, longitudinal, cross-sectional, or longitudinal-sequential
design
correlational: Often, we can’t manipulate our topic ethically, so we measure two variables as they happen
naturally and compare the two. 0 means unrelated 1 means same -1 means negative correlation
(A positive correlation exists when two variables operate in unison so that when one variable rises or falls, the other does the same. A negative correlation is when two variables move opposite one another so that when one variable rises, the other falls.)
experimental: the researcher manipulates one or more variables
* Independent variable: not effected by the study
* Dependent variable: manipulated variable
longitudinal: test the same people multiple times over a a number of years
cross-sectional: compair different people at different stages of their life
longitudinal-sequential: mix of cross sectional and longitudinal test. Compair same people across a few years then do next age group for other half.
