Another group of observational studies are controlled observations. The critical difference is that in controlled observations the researcher dictates a standardised procedure. For example, the Strange Situation (Ainsworth & Bell, 1970) analysed attachment styles using controlled observation. During this study babies were put through a standardised series of episodes in which they were introduced to a new environment and a stranger. During this series of events the baby was left alone with the stranger and the baby’s behaviour when reunited with their mother was analysed.

The most logical advantage of naturalistic observations is the genuine nature of the data collected. As the researchers did not intervene in any way in the bullying study presumably the data collected fully
