Focus groups

Particular type of interview in which a group of participants with a specific quality in common are questioned

Debriefing

Explain all parts and aims and purpose of the experiment

Right to withdraw

Participants can remove themselves from the study at any time

Confidentiality

Keeping participants info secret

Reliability

The likelihood that the study could be replicated (done again) by other researchers, and the same result could be achieved.

Validity

The idea that the results of the study are trustworthy, unbiased, and can be applied to the target population.

Extraneous/Confounding Variable

A variable that influences the results of an experiment.

Internal Validity

The trustworthiness of a study based on the procedural steps put in place by the researcher. A study with confounding variables lacks internal validity.

Construct validity

To investigate if the measure really is measuring the theoretical construct it is supposed to be.

External validity

Order effects

Changes in participants' responses that result from the order (eg. first, second, third) in which the experimental conditions are presented to them.

Fatigue effect

Occurs when participants are asked to take part in several conditions of the same experiment, they may get tired or bored. In either case, they may lose motivation to try their best or their concentration may be impaired, influencing the results.

Interference effects

Exist when the fact that someone has taken part in one condition affects his/her ability to take part in the next condition

Practice effect

When participants are asked to do a task repeatedly, improvement of results may be seen.

Researcher bias

When the beliefs or opinions of the researcher influence the outcomes or conclusions of the research.

Confirmation bias

When a researcher searches for or interprets information in a way that confirms a pre-existing belief or hypothesis.

Funding bias
