experiments ( location , method and design) Flashcards
Single blind procedure
A specific research procedure in which the researchers (and those involved in the study) do not tell the participants what condition of the study they are in
Double blind procedure
A specific research procedure where neither the participants nor the experimenters know which conditions the participants are in
Matched Pairs design
A form of independent groups design where the experimental and control participants are deliberately similar e.g. there is a balance between gender and IQ levels in each group/condition.
Standardised procedure
Keeping everything the same for all participants so that the investigation is fair.
Counterbalancing
A technique used to deal with order effects when using a repeated measures design. With counterbalancing, the participant sample is divided in half, with one half completing the two conditions in one order and the other half completing the conditions in the reverse order.
Location: Online
A location of research where participants are accessed via the internet/social networks/mobile apps etc. Often involves questionnaires but can also be experimental, correlational etc.
Lab experiment
A research method where cause and effect is measured in a controlled/contrived environment, through the control and manipulation of key variables, and where the participants are randomly allocated to experimental/control groups
Location: Laboratory
A location of research where scientific research and measurement can be taken using specialist/large equipment. Conditions and variables are controlled, and procedures are standardised.
Location: Field
A location of research outside of the laboratory, in a natural setting e.g. school, hospital, workplace etc. It has lower levels of control over confounding variables than the laboratory, but can still utilise a standardised procedure.
Field Experiment
A research method where cause and effect is measured in a natural setting, through the control and manipulation of key variables, and where the participants are randomly allocated to experimental/control groups.
Quasi Experiment
A research where the experimenter has NOT deliberately manipulated the IV and participants are NOT randomly allocated. Methods within this category include natural experiments and difference studies.
Natural Experiment
A research method where the IV arises naturally, although the DV can still be measured in a laboratory or any other location of the researcher’s choice. This method would be used when it is unethical to directly manipulate the IV
Independent groups design
An experimental design where participants take part in only one experimental condition.
Repeated Measures design
An experimental design where participants take part in both the control and experimental conditions.
