Research methods designs must be
|
Testability
Falsifiability Replicability |
|
|
Case study
|
Can: study individual, generate research
Not able to be generalized |
|
|
Correlation
|
the relationship between two V’s: positive or negative (closer to 1.0 stronger correlation)
- Correlation doesn't mean causation |
|
|
Third variable problem
|
confounding V
|
|
|
Example of correlation research
|
Epidemiological Research
Behavior monocular genetics |
|
|
Epidemiological Research
|
Prevalence
Incidents Risk factors |
|
|
Prevalence
|
how many people in a situation have a disorder e.g. in USA 1% have schizophrenia
|
|
|
Incidents
|
how many new cases of a disorder do we see develop in a period of time e.g. how many new cases of dementia developed in 2011
|
|
|
Risk Factors
|
what are some of the risk factors of developing PTSD e.g. being a women…gender is a risk
|
|
|
Behavior monocular genetics
|
Family method
Twin method Adoptees method Genome-wide association study |
|
|
Epidemiologists
|
findings more generalisable
|
|
|
Experimental
|
IV is dependent on the DV as to how it varies
CONTROL GROUPS USED |
|
|
IV
|
treatment delivered what is manipulated
|
|
|
DV
|
the change that is measured
|
|
|
Internal validity
|
how tightly controlled is an experiment same age, sex, ethnicity
|
|
|
External validity
|
our experiment generalize to the real world, is the sample big enough
|
|
|
Analogue Experiments
|
define cause and effect relationships by making an inference about a related phenomena observed in the laboratory e.g. Monkey and fake mum
|
|
|
Single case Experiments
|
studies performed on one person, experimenter observes how they respond to manipulation of the IV.
|
|
|
Reversal design ABAB design
|
measure participants behavior in a specific sequence
|
|
|
ABAB
|
1.Initial time period: base line (A)
2.A period were treatment is introduced (B) 3.A reinstatement of the condition of the baseline period (A) 4.A reintroduction of the treatment (B) |
|
|
meta analysis’s
|
1. The researcher defines which studies will be included
2. The effect size within each study is calculated 3. The average effect size across studies is calculated |
|
|
effect size
|
A statistic that puts all results into a common scale
|
