Schema theory simply suggests that all knowledge is stored in different units in the brain. It is believed that memory in human brains works like a videotape which is possible to replay whenever needed; with information being retrieved in much the same form as it was encoded. However, our schemas can be influenced by various factors, such as inner prejudice, which create the concept of reconstructive memory unreliable. Schemas are therefore capable of distorting unfamiliar or unconsciously ‘unacceptable’ information in order to ‘fit in’ with our existing knowledge or schemas. This has been supported by a famous study on reconstructive memory, “War of Ghosts” conducted by Frederic Bartlett in 1932. In this study, British participants were told a Native American folk story, which they had to recall over different intervals of time. They were told to read the story two times, and then told to recall the story that they had just read. They then had to visit the laboratory several times over the course of weeks, months and years for the recall of the story. Within recall, participants created various errors which linked to unsuccessful recall of almost...
