In fact, in many cases like domestic battery, invasion of privacy, and robbery the only evidence there may be is testimonial evidence.What causes the misinformation effect?
Misinformation effect. The misinformation effect happens when a person's recall of episodic memories becomes less accurate because of post-event information. Essentially, the new information that a person receives works backward in time to distort memory of the original event.What would you tell the jurors about the reliability of eyewitness testimony?
But being convincing isn't the same as being accurate. Eyewitness testimony is more fallible than many people assume. 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.Why can Eyewitness accounts vary from person to person?

In the 1970s, psychologist Elizabeth Loftus pioneered research into what has been called the misinformation effect, a term that refers to the distortion of people's beliefs about – and memories of – past experiences as a consequence of receiving erroneous information about those experiences ('postevent information').What is the Loftus study?
She has conducted research on the malleability of human memory. Loftus is best known for her ground-breaking work on the misinformation effect and eyewitness memory, and the creation and nature of false memories, including recovered memories of childhood sexual abuse.How do you give a testimony in court?
