The Hawthorne Effect

15 Dec

The Hawthorne Effect is an old psychological theory that shows that the individuals are likely to change the way they behave if they know that they are being watched. The theory started in a business environment in which they analysed wether the level of light would effect the individuals productivity levels. The results from this very inconclusive as a increase in productivity was noticed but didn’t correlate to either high or low light. However what was interesting was that when the observers left a noticeable drop in the individuals productivity was seen. So there initial criteria was not affective however they where able to conclude that the individuals productivity would increase when the where being observed (Shuttleworth, 2015).

This theory can be linked to my processing idea, in which I want to blur the scene when a face is tracked and not blur when there isn’t one. This idea may prove that individuals will act as they would if they can see that the camera isn’t able to capture faces.
