If someone was killed in front of you would you remember what happened? Many experts are challenging the view that eyewitnesses recounting what they saw is the best way of tapping their memory. Some think brain scans could be the way forward.
So can you remember whom you sat next to? Can you remember what the weather was like? Who was in front of you in the petrol queue? Was it a man or a woman?
Naturally, most of the time we don't remember these details. But what if someone got knifed in the petrol station? Then we become witnesses to a crime. And our ability to recall these minor details may have a significant role in authenticating our memory of the offence.
Some researchers suggest that we shouldn't need to remember these details. They are increasingly questioning the way that the police, lawyers and the courts think about memory. They argue that this conventional model of memory – like a detailed photograph or video film – is fundamentally flawed
