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.
