Outline and Evaluate Factors Influencing Eye Witness Testimony Essay
The term eye witness testimony refers to an area of research into the the true of memory concerning signifi wadt events, it is legally considered to be a reli commensurate narrative of events. However, research into eye witness testimony has found that it can be unnatural by legion(predicate) psychological factors such(prenominal) as, anxiety and stress, constructive memory, selective assist and pencil lead questions. Anxiety and stress can be associated with many factors such as, violence and crime. Clifford and Scott (1978) found that participants who apothegm a deal of a violent event remembered less of the information than a view group who saw a less stressful version.However, Yuile and Cutshall (1986) found that witnesses of a real event had accurate memories of what happened. The police interviewed witnesses and thirteen of them were interviewed five months later. bring forward was found to be accurate, even after a long terminus of time. One weakness of this study was that the witnesses who experienced the highest levels of stress where actually turn over at the event, instead of watching second hand from a film, and this w progress toethorn urinate helped with the accuracy of their memory recall. Selective attention is when the witness is able to describe one detail, giving them less time to pay attention to other lucubrate.It can also be because the witness is more(prenominal) likely to focus on a detail with more emotional significance, such as a weapon. Loftus et al. (1987) showed participants a series of slides of a customer at a restaurant. In on version the customer was holding a gun, in the other the customer held a chequebook. Participants who had been shown the version with the gun relegate tended to focus on the gun itself and not much else. As a result they were less likely to identify the customer as pose to those who had seen the chequebook version.Bartlett (1932) showed that memory is not just a real recording of what h as occurred, but that we make effort after meaning. By this, Bartlett meant that we try to fit what we remember with what we really know and understand. As a result, we quite often tack our memories so they become more sensible to us. He had participants play Chinese Whispers and when asked to recall the detail of the story, for each one person seemed to tell it in their own individual way. With repeating telling, the passages became shorter, perplex ideas were rationalised or forgotten altogether and details changed to become more acquainted(predicate) or conventional.For this research Bartlett concluded, memory is not exact and is distorted by existing preconceptions. It seems, therefore, that each of us reconstructs our memories to conform to our personal beliefs just about the world. This clearly indicates that our memories are anything but reliable records of events. They are individual recollections, which have been shaped and constructed according to our stereotypes, b eliefs, expectations etc. Loftus and Palmer (1974) tested their hypothesis that the language use in eye witness testimony can alter and change memory.They aimed to show that leading questions could distort eye witness testimony accounts, as the account would become distorted by reminders provided in the question. To test this, they asked volume to estimate the speed of motor vehicles using different forms of questions. Participants were shown slides of a auto accident involving a number of cars and asked to describe what had happened as if they were eye witnesses. They were so asked specific questions, including the question About how fast were the cars going when they (hit/smashed/collided/ bumped/contacted) each other? The estimated speed was affected by the verb used.The verb implied information about the speed, which affected the participants memory of the accident. Participants who were asked the smashed question thought the cars were going faster than those who were asked t he hit question. When people were asked a week after viewing the film whether they saw any broken glass at the scene (there was none), people in the smashed group were more likely to say yes. Therefore, a leading question that advance them to remember the vehicles going faster also encouraged them to remember that they saw non-existent broken glass.This suggests that memory is easily distorted by questioning technique and information acquired after the event can mix in with original memory causing inaccurate memory. The addition of false details to a memory of an event is referred to as confabulation. This has important implications for the questions used in police interviews of eye witnesses. In conclusion, eye witness testimony can be influenced by a number of factors, including, anxiety and stress, selective attention, constructive memory and leading questions. They all have a large erect on eye witness testimony and affected the results in many different ways.
