Memory and Eyewitness Testimony
Your memory isn't as reliable as you might think, especially when you're stressed or anxious. Retrieval failure happens when you can't access stored memories, often because the context has changed dramatically from when you first learned something.
Anxiety plays a massive role in how well you remember events. Moderate anxiety can actually help your memory, but high anxiety tends to make it worse. This is crucial for understanding eyewitness testimony - witnesses under extreme stress might not remember crimes accurately.
The weapon focus effect shows that when people see a weapon during a crime, they focus so intensely on it that they remember fewer details about everything else. However, research suggests this isn't just about anxiety - it's also about the weapon being unusual and grabbing attention.
The cognitive interview technique helps police get better information from witnesses by using memory cues and asking them to recall events from different perspectives. It's much more effective than standard questioning methods.
Key Point: Memory models like the multi-store model and working memory model explain how information moves through different storage systems, but real-life memory is far more complex than these simplified theories suggest.
