RF Question Flashcards
Participant Observation
Definition: Observer takes part in the experiment in the experiment to gain deeper insight.
Strength: Can obtain in depth data due to the close proximity.
Non-Participant Observation
Definition: The researcher observes participants without participating in the experiment itself.
Strength: The interviewer has no influence over the behaviours
Covert Observation
Definition: The participants are unaware of the presence of the observer and they are not made aware their behaviour is being observed.
Strength: Reduced chance of demand characteristics
Overt Observation
Definition: The research is open with their participants about observing their behaviour, the participants know they’re being studied.
Strength: Possible to inform participants in advance to obtain informed consent.
Natural observation
Definition: A research method where the participants behaviour is studied in a natural environment
Strength: High ecological validity
Controlled Observation
Definition: Participants behaviour is observed in a controlled environment where the researcher can manipulate the IV
Strength: Can be repeated to test reliability
Event Sampling
Definition: Observer decides in advance what types of behaviour they’re interested in and records all occurrences, ignoring others
Strength: Useful when focussing on select behaviours as reveal the frequency.
Time Sampling
Definition: Observer decides in advance that an observation will only take place during specific time periods, e.g. every 10 mins, only records occurrences during this time
Strength: Observer doesn’t have to be constantly alert so not fatigue influencing accuracy
Inter rater Reliability
Definition: Method to measure external reliability of a test, high when different raters all give consistent results
Strength: Ensures all the data collected in a study is a correct representation of measured variables
Field Experiment
Definition: An experiment carried out in the every day environment of the participant, IV is manipulated but other variables aren’t controlled
Strength: High ecological validity as reflects real life behaviour
Lab Experiment
Definition: An experiment conducted under highly controlled conditions
Strength: Can control extraneous variables to improve validity.
Independent Measures Design
Definition: Where each participant is only assigned to one condition of the IV
Strength: No order effects due to boredom or fatigue
Repeated Measures Design:
Definition: Where each participant is assigned to more than one condition of the IV
Strength: Participant variables won’t be influencing the results so improves validity
Matched Pairs Design:
Definition: There are equal groups where participants are matched on certain characteristics, e.g. gender, age. each in a different condition.
Strength: Prevents both order effects and participant differences affecting results
Operationalisation of the IV and DV
Definition: How you define and measure a specific variable as its used in your study.
Strength: Provides clear and objective explanation of what the research is on, easier to repeat the study.
