Eyewitness accounts provide important evidence that may lead to the identification and arrest of criminal suspects. It is in the trial process that eyewitness testimony is most crucial and is most often correct. However, in some cases, mistaken identification may occur and lead to the wrong conviction of an innocent person. This is due to how the memory retains and processes information after being subjected to traumatic events. It is known that memory functions in different systems which consist of different sub units. The Short- Term memory focuses mostly on seconds to minutes after an event has occurred, yet with the Long-Term memory it focuses on the information that has been processed by the short-term memory, along with information that has arrived suddenly due to any disturbance that has caused trauma to the brain or to how it functions. This is why I hypothesized that the duration of time that the participants have to examine or witness a crime will best influence my research; along with the amount of information being retained. I hypothesized that when a person experiences a shorter amount of time to witness a crime or in this case, examine a picture, the less information will be retained. So the essential question is; how accurate is the memory of an eyewitness that has been influenced by time and the amount of information that is being encountered. The accuracy of the evidence given by an eyewitness is usually determined by the ways the memory process has been affected. Memory is divided into three stages: encoding, storage, and retrieval. At any time in these stages errors may occur to the memory process. In the first stage, encoding, information is best gained by arousal. Though being exposed to extreme arousal or stress causes information to be lost or received incorrectly. At the second stage, storage, the acquired information is stored in the memory
