1 Research Methods Flashcards
What is a laboratory experiment?
A scientific method that involves testing hypotheses by creating controlled conditions in a laboratory setting
What is a field experiment?
A scientific study that is conducted outside of a controlled laboratory setting, in a real world environment.
What is a quasi experiment?
Quasi experiment contain a naturally occurring IV, for example, a memory task with a group of clinically depressed people vs non depressed.
Lab experiment advantages?
- very reliable as they are easily replicable due to the controlled nature.
- has the ability to establish cause and effect
Disadvantages of lab experiment?
- low ecological validity because they are conducted in an artificial study that does not reflect a real life setting.
Field experiment advantages?
Higher ecological validity as behaviour occurs in its own natural environment.
Field experiment disadvantages?
More difficult to replicate exactly as there are no controls
Advantage of quasi experiment?
Useful when it is unethical to manipulate the IV like the experiment with the memory test with depressed and non depressed people, it is unethical to control their mental health.
Disadvantage of quasi experiment
Confounding variables are more likely = less reliable.
What are confounding variables?
Variables other than the independent variable that may affect results.
What is a structured observation?
In which an event or series of events is observed in its natural setting and recorded by an independent researcher.
