Research Methods- Year 1 Flashcards
(47 cards)
What are demand characteristics?
Any cue from researcher or situation that may reveal aims of study.
What are investigator effects?
Effect of investigator’s behaviour on the outcome of the research.
What is randomisation?
Use of chance when designing investigations to control for effect of bias.
What is standardisation?
Using the same formal procedures for all participants in a research study.
What are control groups?
Act as a “baseline” study.
What is a single blind?
Participant doesn’t know the aims of the study so demand characteristics are reduced.
What is a doubleblind?
Both participant and researcher don’t know the aims to reduce demand characteristics and investigator effects.
What is a lab experiment?
Controlled environment where where extraneous and cofounding variables can be regulated.
Participants go to the researcher.
IV is manipulated and effect of DV is recorded.
What is field experiment?
Natural setting.
Researcher goes to participants.
IV is manipulated and effect on DV is recorded.
What is a natural experiment?
Experimenter does not manipulate the IV.
DV may be naturally occurring or may be measured by the experimenter.
What is a Quasi-experiment?
IV is based on a pre-existing difference between people, no one has manipulated this variable.
DV may be naturally occurring or may be measured by experimenter.
What is opportunity sample?
People who are most available like those who are nearest.
What is volunteer sample?
Participants select themselves.
What is random sample?
Every person in target population has an equal chance of being selected.
What is systematic sample?
Participants are selected using a set “pattern”.
What is stratified sample?
Participants are selected according to frequency in the target population.
What is a naturalistic observation?
Takes place where the target behaviour would naturally occur.
What is a controlled observation?
Aspects of observation are controlled, attempting to give the participants the dame experience.
What is a covert observation?
Participants are unaware they are being studied.
What is an overt observation?
Participants are aware they are being studied.
What is a participant observation?
The researcher becomes a part of the group they are studying.
What is a non-participant observation?
Researcher remains separate from the group they are studying.
What is time sampling?
Observations are made at regular intervals, e.g. once every 15 seconds.
What is event sampling?
Target behaviour or event is recorded every time it occurs.
