Leading questions, which are phrased to suggest a specific answer, can significantly distort memory. This influence can alter recollections of an event's details, such as making an accident seem more severe, and can also lead to the creation of entirely false memories for things that never occurred, as demonstrated in studies where participants recall seeing non-existent broken glass after hearing suggestive language.

Leading Questions and Memory Distortion

In a foundational 1974 study, Elizabeth Loftus and John Palmer explored how leading questions could influence memory. They presented films of car accidents to 45 college students and asked them to estimate the speed of the vehicles. The critical manipulation was the verb used in the question, 'About how fast were the cars going when they ___ each other?' The verb was varied with words like 'smashed,' 'collided,' 'bumped,' 'hit,' or 'contacted.' The results showed a clear correlation between the intensity of the verb and the speed estimate: 'smashed' yielded an average estimate of about 41 mph, 'collided' 39 mph, 'bumped' 37 mph, 'hit' 34 mph, and 'contacted' 32 mph. In a follow-up a week later, participants in the 'smashed' group were also more than twice as likely to falsely recall seeing broken glass, demonstrating that post-event information can distort memories and even create false ones.

Analyze the investigator's question in the scenario below. Identify the specific element that could distort the witness's memory and describe two potential distortions that might occur in their recollection of the event as a result.

Eyewitness Memory Analysis

An eyewitness saw a person quickly leave a store carrying a backpack, just before a fire alarm sounded. Later, an investigator asks the witness, 'What color was the weapon the person was holding?' Even though no weapon was initially reported, what is the most likely effect of this question on the witness's memory?
