observational technique

  • Observational techniques
    • Observation = a  way of seeing or listening to what people do without having to ask them
    • Observation is often used within an experiment as a way of assessing the DV
    • Evaluation of observations in general:
    • Strength = capture what people do
    • People often act differently from how they say they will in self-report methods
    • Observations give an insight into spontaneous behaviour
    • Limitation = risk of observer bias
    • Researchers interpretation of the situation mat be affected by expectations (bias can reduced by using more than one observer)
    • Observational techniques:
    • Naturalistic
    • Controlled
    • Covert
    • Overt
    • Participant observation
    • Non-participant observation
  • naturalistic observation
    •  takes place where the target behaviour would normally occur
    • Strength = high external validity
    • In a natural context, behaviour is likely to be more spontaneous => more generalisable to everyday life
    • Limitation = low control
    • There may be uncontrolled CVs/EVs => makes it more difficult to detect patterns
  • controlled observation
    • some control/manipulation of variables including control of CVs/EVs
    • Strength = can be replicated
    • More easily repeated due to standardised procedures => findings can be checked to see if they occur again
    • Limitation = low external validity
    • Behaviour may be contrived as a result of the setting => findings cannot be applied to everyday life
  • covert observation
    • participants are unaware they are being studied
    • strength = demand characteristics are reduced
    • pps do not know they are being watched so their behaviour will be more natural => increases internal validity of the findings
    • Limitation = ethically questionable
    • People may not want behaviour to be recorded (even in public) => pps right to privacy may be affected
  • overt observation
    • Participants are aware of being studied
    • Strength = more ethically acceptable
    • pps have given their consent to being studied - they have the right to withdraw if they wish
    • Limitation = demand characteristics
    • Knowledge of being studied influences behaviour => reduces the internal validity of the findings
  • participant observation
    • researcher becomes part of group they are studying
    • Strength = can lead to greater insight
    • Researcher experiences the situation as the pps do - this enhances the external validity of the findings
    • Limitation = possible loss of objectivity
    • The researcher may identify too strongly with those they are studying - this threatens the objectivity and internal validity of the findings
  • non-participant observation
    • Researcher remains separate from the group they are studying
    • Strength = more objective
    • Researcher maintains an objective distance so less chance of bias - may increase the internal validity of the findings
    • Limitation = loss of insight
    • Researcher may be too far removed from those they are studying - may reduce the external validity of the findings
