Theories Flashcards
3 parts of researching human development
research - reliability and validity of ideas
theory - change over time, name may change
scientific verification - replication of methods
the 2 purposes of study of human development
to develop theories
to live longer/better/fitter
The study of human development provides no certain truths because 3
investigators can disagree - more scientific verification and uncertainty and ideas
humans are complex - social/emotional/intellectual levels - not the same but we try and reduce complexity
knowledge is advancing quickly - anatomy is one thing that hasnt changed in a while
3 processeses of studying development
hypothesis - if…then… assumption of what they think might happen
research methods
research design - overall plan that permits the best possible test of the hypothesis
If you use more techniques in your research design
the more robust your data would be
correlational design (3)
to develop a correlation coefficient which states a potential relationship
- happier because they exercise on a regular basis
- pos/neg relationship - not cause and effect
experimental designs (3)
dependent and independent variables
- multiple dependent to collect info about
- manipulate independent variable
infer cause and effect
2 types of experimental designs
LONGITUDINAL design - collect info over a long period of time (decades for lifestyle habits and diseases)
- dropout - move/disappear/dont want to anymore
- they might figure out which is the placebo
CROSS SECTIONAL design - under effects of something over time, studying different age groups and study them at the same time
- reduce the risk of the 2 faults
5 research designs
experimental correlational systematic observation self report case studies
systematic observation
natural/contrived environment - tells you what but not why - understand behaviours
change behaviour because someone is watching so they do things they dont usually do
self report
questionnaires - tell you some of the whys
continuous vs discontinuous
steady slope vs stairs
continuous is building on the skill that we already have - slow
discontinuous - rapid - certain skills we can engage in at different times - like puberty - at a particular time something happens to us but we didnt spend time continuously for it to happen - (maybe yes because endocrine reaches a certain point)
4 organizing theories
continuous vs discontinuous
one course or more
influence of nature and nurture
lifespan perspective
one course or more
multiple dimensions - motor skills with physical and cognitive aspects
a course is a dimension - desire for social interaction
some skill sets (few) can only get through one course
case studies
evaluation on a single unit
Nature vs nurture
genetic material you are born with vs influences and things that you encounter
stability (4) vs platicity (3)
nature vs nurture
unchanged as they age - fear can be shaped by early exposure
- sociological skill set/fear can be inherited
- change and grow and develop then decline
- things that we cant change
- skillset can be changed
- keep growing and changing
- things we can change
twin studies
fear, alcohol, color and height are same - genes play a huge role
the way that you’re raised (2)
own likes and dislikes
potential for success can differ from home vs public school
Lifespan perspective 5
broad, wellness perspective - social, intellectual, emotional multidirectional 1960s - adults are all the same plastic age, history and non-normative graded
age graded 2
biologically driven - particular time frames of our lifespan like puberty and permanent teeth
socially driven - license, retirement, adulthood
history graded 2
eras - cohort - experienced similar things that make you diff from other cohorts
