(32 cards)
what does GROVE stand for?
Generalisability
Reliability
Objectivity
Validity
Ethics
what is generalisability?
how well a study’s findings can be applied to behaviour outside the research situation
related - ecological validity
what things do you need to look at when considering the generalisability of results?
sample - was it representative?
setting - was it realistic?
what is a sample?
the participants that take part in the research/study
related - target population
what is the target population?
the group of individuals you want to apply the findings to (the sample should be representative of the target population)
related - sample
what is mundane realism?
everyday tasks like going to school (high mundane realism = realistic task)
related - ecological validity, generalisability
what is ecological validity?
the extent to which you can apply findings to the real world
related - generalisability
what is validity?
the accuracy of your research
related - internal validity, extraneous variables, demand characteristics, researcher bias
what is internal validity?
the extent to which your experiment or observation measures what it intends to measure
related - validity
what are extraneous variables?
any variable other than the one you are measuring that could impact the outcome of your research
related - validity, internal validity, demand characteristics, researcher bias
what is a confounding variable?
an extraneous variable which systemically affects the participants in one condition but not another
related - validity, extraneous variable
what are demand characteristics?
the cues that participants use to work out the aim of the study/what the researcher expects to find (causes them to change their behaviour)
related - validity, internal validity, extraneous variables , researcher bias
what is researcher bias?
when the researcher intentionally/unintentionally impacts the outcome of the research
related - validity, internal validity, extraneous variables, demand characteristics
what is a standardised procedure?
a step-by-step method on how to carry out the study which reduces researcher bias
related - validity, researcher bias
what is a benefit of quantitative data?
it is numerical so less likely to have researcher bias as it can’t be interpreted in different ways
what is a blind study?
when participants are unaware of the aims and key facts of a study to try and remove demand characteristics
related - validity, demand characteristics
what is social desirability?
when participants give a response or behave in a way that they think will make them more socially desirable
related - validity, demand characteristics
what is reliability?
how consistent your results are (so if the experiment is repeated the results should be the same)
what is test-retest reliability?
when you do the same test on the same people repeatedly, to see if you get the same result
what is inter-observer reliability?
the amount of agreement between two observers (if this is higher it means the observation is more reliable)
how can you improve inter-observer reliability?
use a behaviour checklist (make it specific)
train the observers
what is objectivity?
when an experiment/the results are not subject to interpretation
what are the four ethical principles all psychologists must follow?
respect, competence, responsibility, integrity
ethics - what does respect mean?
the psychologist or researcher should show respect for the dignity and individual differences of participants and recognise that all humans are worthy of equal moral consideration
