Research Abstract

The witnesses who saw any crime testify relying on their memories. Such memories are usually reconstructive in nature and the accuracy of the memories is influenced by the social information given to the witnesses. This influence was detrimental effects on the formation of memory people constructs about the events they experienced. In this research project, we investigated the effects of media on which social information is conveyed and the effect of telling lies, the influence on the ear-witness were explored.
