types of experiments. Flashcards
what is a lab experiment
high level of control over all the variables in the study.
takes place in an artificial controlled environment.
there is usually standardised procedure
participants know they are taking part in a study - may not know the true aim.
what is a field experiment
conducted in naturalistic settings.
the in is still deliberately manipulated by the researcher but participants are not aware they are participating in research.
what is a natural experiment
conducted in the every day environment of the participant
no control over the IV
what is a quasi experiment
the IV is pre-existing difference between people (eg age or gender).
participants cannot be randomly assigned to conditions
because if this it is not a ‘true’ experiment.
what is standardised procedure.
when procedures used in research are kept the same
a prescribed procedure to be followed routinely.
what is reliability
a measure of whether something stays the same
how consistently a method measures something
what is internal validity
the extent to which a research study accurately identifies a causal between variables, ruling out alternative explanations.
what is ecological validity
the extent to which the findings of a study can be generalized to real world settings and situations.
what is mundane realism
the degree to which an experiment or study resembles real life situations and experiences
what are demand characteristics
cues or hints within a study that may lead participants to guess the researchers hypothesis or expected outcomes, potentially influencing their behaviour
what is random allocation
assigning participants to different groups or conditions in an experiment in a random and unbiased manner
standardised procedure
a consistent and uniform set of instructions and methods used in a. research study.
