The Observation

In a psychology class the teacher will usually go over observational studies and how they don't always work because the subject will act differently when conscious of being observed. The same concept applies to when people are making a documentary or getting their photo taken: they act differently. However, after a certain amount of time, the subject will not notice being observed. Although this takes some time, it can work and you can capture a natural subject. Here, the subjects learned to ignore the camera and the sound it makes, but one of the subjects brought in their own camera, and he experienced a subject acting as they would when being observed, and that is a term psychologists call discrimination.
