I have seen a TV program talking about an interesting 'mind control' magic/experiment. I cannot find this video clip online so I have to describe what I saw in words.
The video (some sort of documentary?) begins with two persons walking on the street. One person is the host and another is the subject of this experiment.
Both person walking down the street and do some casual talking. While they walk, the host introduces the area and so on, points to some interesting scenes around (for example graffiti and people on the street etc...). Also, an one instance, there was a boy skating and the boy almost hit the subject. Anyway, everything looks perfectly normal and natural.
Then, they reached an art gallery. They walk into the gallery and then in a room, there is a covered painting there. The host asked the subject to tell, what would be on the paint.
The subject mentioned a couple of things, some thing like the color of the paint, the object on the paint etc, etc... Guess what? As you certainly can predict, when the host reveal the paint, it looks exactly like the one described by the subject.
The host then explain to the subject that everything and everybody he had seen during this experiment are controlled and are carefully selected. For example the boy skating, the people on the street, the graffiti etc. The host then suggested that its what he (the subject) saw lead him to think (about the paint) the way the host would like him to think.
So, my question here is that assume this video is not just a fake camera trick, then what psychology theory is behind it? Could anybody offer some links to academic papers in this area?
