An eyewitness is a person who has seen a crime occur and can therefore give information about what actually happened to hopefully assist the police find the offender and prosecute them for the crime. There are two main roles that an eyewitness performs. They are to recall information about the crime that has occurred or to identify the person that they saw commit the crime (Ainsworth, 1998). An eyewitness may also be asked to make a testimony in court in order to produce evidence that could help to convict the offender. These three roles of an eyewitness all largely rely on the psychological process of memory.

Identification of Area:
The main area of psychology that is used in relation to eyewitnesses is memory (Lecture, 2014). The most important type of memory used by an eyewitness is their episodic memory (Lecture, 2014). Episodic memory is the memory of an event that you personally experienced (Burton, Westen, & Kowalski, 2012). Eyewitnesses are required to access their episodic memories when assisting police with the events that happened and with helping police identify the offender. In order to retrieve these memories from their episodic memories, an eyewitness has to access two areas of their explicit memory; recall and recognition (Burton, et al., 2012). Recall is consciously bringing events of memory into awareness from long-term memory without the use of a cue (Burton, et al., 2012).

Evidence from the above articles suggests that eyewitness’ have poorer recall and recognition for the appearance of an offender as well as everything else going on in the location when there is a presence of a weapon (Pickel, et al., 2006; Pickel, 1998). It was also found that the memory of a witness is not only negatively effected by the presence of a weapon that is seen as a threat, but also and even more so by an object that is unusual (Pickel, et al., 2006; Pickel, 1998).

In conclusion, evidence suggests that eyewitness identifications are not reliable, however more research is needed before this can be concluded.
