Research Methods Flashcards
What are the two types of OBSERVATIONAL data collection?
- case studies
* field observational studies
what are case studies?
People in rare situations, studied over time that do not allow for group studies; humanizes science
What is the John Money case study?
Obtained a young male infant “David” who lost his genitals and sex reassignment surgery changed him to “Brenda”.
- now raised as a girl, Money claimed that gender identity is nurture-based and child can “learn” to accept another gender
- Money saw what he wanted in order to confirm his hypothesis, disregarding “Brenda’s” feelings of becoming “David”, a boy like he was born
What are Field Observational Studies? What was example used in class? Give your own example.
Involve detailed observation of human (child, in this case) behaviour in real world environment (not stimulated).
*Class ex: observe aggression in boys vs girls. Found that experimenter bias can affect results –> ex: over notice forms of aggression in girls because it is not the norm.
What are two types of correlational studies? What to remember about correlation?
- archival studies
- survey studies
- *Correlation does not lead to Austin!
Archival Studies
looking through archives
ex: SAT scores vs SES = lower SES results in lower scores
Survey Studies
surveying individuals from a population
*ex: intro/extroverted children and # of friends each may have
Limits of Survey Studies?
- age can affect child’s reading/intellectual ability
- retrospective reports leads to memory bias and inaccuracies
- parent/teacher/peer reports may be biased
Concepts of Experimental research?
- IV- being manipulated
- DV- being measured
- experimental control- set up is exactly the same to contro for variables
- random assignment- ensures groups are equalized in beginning and have a chance at any level of IV
3 types of experiments?
true lab
field experiment
quasi experiment
true lab
general lab setup with ideal conditions and variables that can be manipulated on demand; all very controlled
field experiment
out in real world, can’t really control the environmental variables; only control over IV
quasi experiment
like true lab but lacking component of random assignment on at least variable (age, gender, SES)
*NO CAUSATION
Cross-Sectional
*data collected at one specific point in time
PRO: quick, cheap, easy, demonstrates age differences
CONS: cohort effect in play, cant say of development is/will be continuos or discontinuous
Longitudinal
Data collected for same group of ppl repeatedly over period of time
PRO: tells of developmental course , links bw early experiences and later outcomes, eliminates some fo cohort effect
CONS: CE still present, expensive, time, practice effects, selective attrition (loss of certain kinds of participants)
