In the 1900s, psychology evolved to encompass a discipline that would help to understand criminal behaviors. This focus arose from the belief that once the behaviors are well-understood, effective strategies and approaches can be developed to address them. Law enforcement agencies have the responsibility of identifying criminal elements in the society by gathering evidence sufficient to convince the jury without any doubt that an offender actually committed the alleged crime. Reaching this conclusion requires the positive identification of persons who committed a certain crime. Considering that law enforcement agencies are in most situations absent at the time of committing the crime, they must rely on people who witness the crime to positively identify and provide bystander evidence in a court of law. However, this approach introduces challenges since eyewitnesses may wrongly identify people who they believe (or they are convinced) committed a crime against them or another party. This situation creates the possibility of wrongful convictions. In this case, forensic psychology becomes important. This paper does not offer histological accounts of forensic psychology and its application to studies such as crime prevention. Rather, it dwells on the deployment of forensic psychology in authenticating eyewitness’ evidence with a particular focus on its precision and effectiveness in court. Literature Review: The Deployment of Forensic Psychology in Authenticating Eyewitness Statements Eyewitness Memory The inability of human memory to accurately recount events in their chronological order of occurrence constituted one of the dominant themes in early psychological studies. Using various experimental approaches, scholars, including Herman Ebbinghaus, began discovering various fundamental properties that characterized the functioning of human memory. According to Sporer, Penrod, Read, and Cutler (1995), one of the models that emerged from early studies on memory functioning theorized it a component that operates in the three stages. The first stage entails the acquisition phase where memories are established or formed. The retention stage is regarded as a memory holding point. Lastly, people retrieve the information stored in their memory. Arguably, when giving eyewitness’ testimonies, the degree to which one can acquire, retain, and retrieve information in his or her memory just as it was initially obtained determines the accuracy level of the evidence. Despite the fact that theories concerning memory have extended beyond the basic model, they are still crucial in the debate on eyewitness memory. Indeed, research on eyewitness testimony as admitted in a court of law focuses on the acquisition or the incident of observation, the time that elapses after observation (retention), and the presentation of testimonies (retrieval) (Jones, 2014). In such studies, researchers consider various issues, including social variables such as the interrogator’s state of mind, and various situations, for instance, the nature of the crime. According to Loftus and Zanni (1975), variables such as the type of questions administered and individual variables, including the age of a witness, determine the reliability of witness testimonies. Therefore, such variables constitute important aspects that have been widely researched in forensic psychology. Indeed, various general problems that have been reported in the validation of eyewitness testimonies are evident
