If you are resident of New Orleans, how would you describe personal events that occurred shortly before August 2005? Would you refer to them as happening "back in July of 2005" or would you describe them as happening "just before Hurricane Katrina"? If you live in Oregon, would you make reference to Hurricane Katrina? A team of researchers, led by psychologist Norman R. Brown from the University of Alberta, investigated how public events (e.g., war, natural disaster, terrorism) shape our personal memories.
