The Influence of an Interpolated Experience upon Recognition

Abstract

It was demonstrated in a previous experiment that an experience interpolated between an original experience and its recall may bring about changes in the points of emphasis in the recall of the original experience. Moreover, details of the interpolated experience may be recalled as if they had formed part of the original experience. These results were taken to mean that two experiences of a related kind may become merged in memory into something akin to Bartlett's notion of an organized mass of past experiences. In the experiment here reported, the original experience was the hearing of a story, and the interpolated experience the seeing of a picture which illustrated part of the story. When in a recognition test subjects were asked to select from three alternatives (including the original) the one version which was “most like the original story,” a proportion of them preferred to the original story a version which differed from the original by including a number of details from the picture. Asked about details, all the subjects tended to place details from the picture in the story, even if they had not been mentioned there. The results of the two experiments are thought to show that irreversible changes are brought about in the memory of an experience by subsequent experiences of a related kind.
