All types of research in Psychology involve some element of observation, not just observational studies. For example, when we use self report measures we observe the responses of the participants, and when we carry out laboratory experiments, we observe the behaviour of our participants, and so on.
Observation studies are a type of study where the researcher observes a situation and records what happens, but does not manipulate an independent variable.
Observational studies therefore tend to be high in ecological validity as there is no intervention, and if the observer remains undetected, then the method avoids any problems with experimenter effects.
On the other hand, observational studies can be difficult to replicate.
