False Memories The US legal system places a lot of importance on eyewitness memory
Assignment 2: False Memories The US legal system places a lot of importance on eyewitness memory. Most people would report that they can accurately convey what they saw in a particular situation. However, these ideas are not supported by research. Instead, research shows that memory is quite malleable and is affected by many factors. This research repeatedly demonstrates that people do not remember exactly what they experienced.
This module’s experiment will show you firsthand how memory for events is not always one hundred percent accurate. Access the CogLab demonstration False Memory. Follow the instructions to complete the demonstration to familiarize yourself with false memory. Then locate at least one research study from a peer-reviewed journal that examined how eyewitness memory can be affected by false memories. Based on your research, respond to the following situation: You are considered to be an expert in false memories, and a local district attorney has therefore requested your expertise on the following case: On Tuesday, March 6, 2007, a bank was robbed in Slidell, LA.
It was just after opening time, 9:04 a.m., and there were barely any customers, when a car arrived and parked in the side parking lot of the bank. Two men came out of the car and walked to the entrance. Both wore dark clothing. Upon entering the bank, they held out guns and asked for the manager. When the manager identified herself, the smaller of the two robbers ordered her to open the safe.
Meanwhile, the other robber, a tall, and burly man, walked around holding his gun in his outstretched arm, and threatening the remaining employees and customers. The manager complied and the smaller robber collected all the money and valuables from the safe. After five minutes, the big robber asked if his companion was ready to go. When he was, the two ran back to their car, and drove away. The district attorney has asked that you create a presentation about false memory and explain how it might influence this case.
He asks that you specifically address the following: Describe false memory and false memory experiments. Use the CogLab experiment to illustrate false memory experiments, special distracters, and normal distracters. Describe at least one research study from a peer-reviewed journal that investigated how eyewitness memory can be affected by false memories. Explain how false memory might influence this particular case. Use specifics from the description of the case, the CogLab experiment, and research to support your answer.
Using evidence from the case, the CogLab experiment, and outside research, justify why eyewitness testimonies should or should not carry weight in criminal proceedings. Discuss any procedures which can increase or reduce the occurrence of false memories when reporting eyewitness events. Remember, your presentation is designed to help the jury understand false memory and how it might influence the eyewitness testimony of this case. You will have ten minutes to present. Since this is a legal case, you must include formally written slide notes (proper grammar, proper paragraphs, APA formatting, and academic tone) with research to support your claims. The presentation will be a legal document in this case, so make it worthy of being legally binding! Develop a 5–6-slide presentation in PowerPoint format.

Artificially created memories, known as false memories, pose significant concerns in legal contexts, especially when eyewitness testimonies are pivotal in criminal proceedings. False memory research has revealed that human recall is susceptible to distortion, contamination, and suggestion, which can lead to individuals confidently recalling events or details that never occurred (Gordon & Wasson, 2020).
Understanding how these misremembered details can influence judicial outcomes necessitates examining experiments like the CogLab demonstration, which illustrates the malleability of memory through distracter tasks.
The CogLab false memory experiment involves presenting participants with a list of words related to a common theme. When asked to recall the words, many participants falsely remember words that were not on the list but were semantically associated with it. The use of special distracters—semantically related but distinct words—heightens false recall, whereas normal distracters—unrelated words—tend to reduce erroneous memory formation (Roediger et al., 2001). This experiment exemplifies how reconstructive memory processes are vulnerable to suggestive influences, a phenomenon that has profound implications for eyewitness accounts.
Research studies have consistently demonstrated how false memories can distort eyewitness testimony. For instance, Loftus and colleagues (2010) conducted experiments where participants were shown a simulated crime involving a man smashing a car. Some participants were subtly led to believe the man was wearing a green shirt, although this was false information provided through suggestion. When later asked to describe the suspect, many falsely recalled the individual wearing a green shirt, despite never having seen it. This study highlights how post-event suggestions and misleading information can implant false
details into witnesses’ memories, which can alter their recollections significantly (Loftus, 2010).
In the context of the case described—an armed bank robbery in Slidell, Louisiana—false memories may influence witnesses’ perceptions and recollections of the robbers' appearance, number, or actions. For example, a witness might unintentionally conflate details from other similar crimes or media reports, leading to a distorted or inaccurate recall of the perpetrators’ clothing or facial features. The stress and chaos inherent in robbery scenarios can further impair accurate memory encoding, making witnesses more susceptible to suggestion or incorrect details. Such inaccuracies could lead to wrongful accusations or misidentification, emphasizing the need for caution when relying solely on eyewitness testimony.
Given the malleability of human memory demonstrated through experiments and research, eyewitness testimonies should be approached with skepticism, especially in high-stakes legal cases. While they can provide valuable clues, they are inherently fallible and vulnerable to false memory formation. To mitigate these risks, procedures such as the use of double-blind lineups, standardized interviewing techniques (e.g., Cognitive Interview), and avoidance of leading questions are essential in reducing suggestion and contamination (Wells & Olson, 2003). These procedures have been shown to decrease false identifications and improve the accuracy of eyewitness accounts.
Furthermore, it is necessary for the legal system to incorporate scientific findings about memory’s reconstructive nature when evaluating eyewitness evidence. Expert testimony on false memories can help juries understand the potential for inaccuracies, fostering more critical evaluation of eyewitness reliability. Ultimately, while eyewitness testimony should not be entirely dismissed, it must be corroborated with physical evidence and subjected to procedures that limit false memory formation, ensuring justice is both fair and scientifically informed.
