It also shows the role of schema in guiding recall. In law a witness is someone who, either voluntarily or under compulsion, provides testimonial evidence, either oral or written, of what they know or claim to know.

You might ask students if they ever compared their memory of an event to an actual recording of the incident and discovered discrepancies. So when they communicate about the crime later, they not only reinforce common memories for the event, they also contaminate each others memories for the event (Gabbert, Memon, & Allan, 2003; Paterson & Kemp, 2006; Takarangi, Parker, & Garry, 2006). Loftus's research has demonstrated the malleability of memory, and her work has had a particular influence on the use of human memory in criminal testimony and other forensic settings. Learn Mem. Start and end at the designated times. It involves a more complicated process than might initially be presumed. More specifically, the assumption that memory provides an accurate recording of experience, much like a video camera, is incorrect.
