Observing of participants behaviour through controlled or uncontrolled conditions. Naturalistic observation A research method where the participant’s behaviour is studied in a natural environment. Controlled observation Participant’s behaviour is usually observed in a controlled environment (laboratory) where the researcher can manipulate the IV. Overt observations The research is open with their participants about observing their behaviour. The participants know that they are being studied. Covert Observations The participants are unaware of the presence of the researcher and they are NOT made aware that their behaviour is being observed. Inter-rater reliability The method of measuring the external consistency of a test. This method is carried out by different “raters” giving consistent estimates/measures of behaviour.
