Faulty eyewitness identification and testimony can lead to wrongful convictions.

Wrongful Conviction

Eyewitness suggestibility refers to the susceptibility of witnesses to be influenced by interview practices and questioning methods, which can lead to flaws in their testimony. Awareness of these flaws has led to modifications in how witnesses are interviewed and how lineups are conducted to decrease suggestibility.

The process of bringing up old memories is called memory reconstruction. When a memory is retrieved from long-term storage into short-term memory, it becomes flexible and susceptible to modification. During this process, old memories can be unintentionally combined with new events, which alters what a person believes they remember and can result in inaccuracies or distortions.

A key witness in a trial provides testimony about an event that occurred several months ago. Based on your understanding of how memories are retrieved, evaluate the potential reliability of this testimony. In your answer, explain the cognitive process that can cause a person's recollection of an event to change over time, even when they are trying to be completely truthful.

Reliability of Eyewitness Accounts

An individual witnesses a minor traffic incident. When first questioned, they state they are unsure about the color of the car involved. A few days later, they overhear a friend confidently state the car was blue. When questioned again, the witness now reports with certainty that they saw a blue car. Which of the following best explains this change in the witness's recollection?

Different components of a single memory, such as the visual elements, smells, and the time an event occurred, are not stored together. Instead, these various parts are stored in different places.
