Research Methods - Types Of Research Methods Flashcards
What are the three main types of research methods?
- Lab
- Field
- Quasi
What is a strength of lab experiments?
Cause and effect can be established
What is a weakness of lab experiments?
It is less ecologically valid
What is a strength of field experiments?
More ecologically valid
What is a weakness of field experiments?
Lacks control and it is hard to establish what the cause is
What is a strength of quasi experiments?
It allows us to study the effects of variables that psychologists can’t manipulate
What is a weakness of quasi experiments?
There is no control over confounding variables
What is an IV?
Variable that is manipulated
What is a DV?
A variable that is measured
What is an observation?
It involves watching a ppt and recording relevant behaviour
What are the 8 types of observation?
- Unstructured
- Structured
- Covert
- Overt
- Ppt observer
- Non-ppt observer
- Naturalistic
- Controlled
Where are naturalistic observations carried out?
In the field (natural setting)
What is a positive and negative of naturalistic observation?
Positive = observe natural behaviour so more valid Negative = lack of control and difficult to establish cause
What happened in a controlled observation?
Psychologists control all the factors that might alter the behaviour and therefore hide the behaviour caused by the IV
What is a positive and negative of controlled observations?
Positive = setting is standardised so easier to establish cause Negative = the situation is artificial and so lacks ecological validity
