It is a legal term, it refers to an account given by people of an event they have witnessed.Eyewitness testimony is an important area of research in cognitive psychology and human memory.

  The claim that eyewitness testimony is reliable and accurate is testable, and the research is clear that eyewitness identification is vulnerable to distortion without the witness’s awareness. More specifically, the assumption that memory provides an accurate recording of experience, much like a video camera, is incorrect. Memory evolved to give us a personal sense of identity and to guide our actions.
