High Quality Content by WIKIPEDIA articles! An eyewitness testimony is a statement given under oath by a person present at an event who can describe what happened. During circumstances in which a child is a witness to the event, the child can be used to deliver a testimony on the stand. The credibility of a child, however, is often questioned due to their underdeveloped memory capacity and overall brain physiology. Researchers found that eyewitness memory requires high-order memory capacity even for well-developed adult brain. Because a child`s brain is not yet fully developed, each child witness must be assessed by the proper authorities to determine their reliability as a witness and whether or not they are mature enough to accurately recall the event, provide important details and withstand leading questions.
