- Selective perception
Selective perception may refer to any number of
cognitive bias es inpsychology related to the way expectations affectperception .For instance, several studies have shown that students who were told they were consuming
alcohol ic beverages (which in fact were non-alcoholic) perceived themselves as being "drunk ", exhibited fewer physiological symptoms of social stress, and drove a simulated car similarly to other subjects who had actually consumed alcohol. The result is somewhat similar to theplacebo effect .Fact|date=October 2007In one classic study on this subject related to the
hostile media effect (which is itself an excellent example of selective perception), viewers watched a filmstrip of a particularly violent Princeton-DartmouthAmerican football game. Princeton viewers reported seeing nearly twice as many rule infractions committed by the Dartmouth team than did Dartmouth viewers. One Dartmouth alumnus did not see any infractions committed by the Dartmouth side and erroneously assumed he had been sent only part of the film, sending word requesting the rest. [Hastorf, A. H. & Cantril, H. (1954). They saw a game: A case study. "Journal of Abnormal and Social Psychology", 49, 129-134.]Selective perceptions are of two types:
