In a study I conducted with Yonelinas at Davis, we presented volunteers with highly arousing emotional photos (mostly unpleasant photos of mutilated bodies and acts of violence) as well as neutral photos (people reading in a bookstore or employees working in an office). We then tested the volunteers’ memory of half the photos immediately after presenting them; we tested their memories of the rest of the photos twenty-four hours later. At first, it seemed that the volunteers’ memories of the emotional and neutral photos were not different; they remembered them equally well. However, when they came back to the lab a day later, something had changed. Now their recollection of the emotional photos was better than that of the neutral photos. The volunteers’ memories were not always more accurate, but they reported they were more vivid.”
