observational techniques

    Cards (33)

    • pilot studies
      small scale practice studies conducted prior to the research
    • why are pilot studies conducted?
      Pilot studies are carried out to identify potential problems, so that they can be fixed.
    • naturalistic observation
      the observation is in a natural, day-to-day environment. Behaviour is studied in a natural situation and the researcher does not interfere in any way.
    • strengths of naturalistic observation
      High ecological validity due to observing real-life situations
      High external validity as it was done in a natural environment
    • limitations of naturalistic observation
      Little control over confounding and extraneous variables
      Replication can be difficult as the environment can not be exactly replicated again
    • controlled observation
      The observation is in a controlled, lab environment and variables are controlled by the researcher
    • strengths of controlled observation
      Researcher is able to focus on a particular aspect of behaviour
      Easy replication
    • limitations of controlled observation
      Environment may feel unnatural which may influence participants’ behaviour.
      Low mundane realism = low ecological validity.
    • overt observation
      Participants know they are being observed.
    • strengths of overt observation
      Lack of ethical issues – informed consent is given
    • limitation of overt observation
      Demand characteristics which reduces validity of findings
    • covert observation
      Participants do not know they are being observed until after the study
    • strengths of covert observation
      Natural behaviour as participants are unaware of observation
    • limitations of covert observation
      Ethical issues including informed consent and invasion of privacy.
    • participant observation
      Researcher takes part in the observation as a participant.
    • strengths of participant observation
      May provide special insights into behaviour from inside that may otherwise not be gained. Increases the validity
    • limitation of participant observation
      Loss of objectivity as the researcher may start to identify too strongly with the participants
    • non-participant observation
      Researcher does not take part in the observation – they are only watching or listening to the behaviour of others.
    • strength of non-participant observation
      Researcher can be more objective as less likely to identify with participants since watching from outside of the group.
    • limitations of non-participant observation
      May loose valuable insight from observing on the sidelines
      Open to observer bias
    • observer bias
      the observer’s expectations affect what they see or hear which reduces validity of observation.
    • what is a remedy to observer bias
      checking inter-observer reliability
    • inter-observer reliability
      the extent to which two or more observers are observing and recording behaviour in the same way. If there is 80% agreement on the observations, the data has high inter-observer reliability.
    • unstructured observation

      Continuous recording where the researcher writes everything they see during the observation
    • strength of unstructured observation
      Qualitative data – more richness and depth of detail
    • limitation of unstructured observation
      Qualitative data is more difficult to record and analyse
      Greater risk of observer bias – observers may only record eye catching behaviour or behaviours they want to see
    • structured observation
      An observational study using a predetermined list of behaviours and sampling methods to record the participants’ behaviour
    • strength of structured observation
      Good for infrequent behaviours
    • limitation of structured observation
      Counting errors for infrequent behaviours
    • what systems do researchers use in structured observations to organise
      1. behavioural categories
      2. time sampling
      3. event sampling
    • behavioural categories
      the target behaviour being observed is broken up into more precise components which are observable and measurable
    • time sampling
      recording of behaviour within a timeframe that is pre-established
    • event sampling
      counting the number of times a particular behaviour is carried out.
