A new study has shown that we tend to remember the bad times better than the good. The study, from Boston College psychologist, Elizabeth Kensinger and colleagues, has (36) that we retain and bear in mind events that carry negative emotional burden. Her research shows that whether an event is pleasing or aversive (厌恶的;引起厌恶的)seems to be a (37) determinant of the accuracy with which the event is remembered, with negative events being remembered in greater detail than positive ones. To (38) her theory, Kensinger gives the example of a sight of a man on a street holding a gun. After seeing the man, people remember the gun clearly, but they forget the details of the street. Functional Magnetic Resonance Imaging (FMRI) studies have shown (39) cellular activity in emotion processing regions at the time that a negative event is (40) . The more activity in the orbitofrontal cortex and the amygdala, two emotion-processing regions of the brain, the more likely an individual is to remember details (41) linked to the emotional aspect of the event, such as the exact appearance of the gun. Kensinger argues that recognizing the (42) of negative emotion on memory for detail may, at some point, save our lives by guiding our actions and allowing us to plan for similar future (43) . "These benefits make sense within an (44) framework. It is logical that (45) would be focused on potentially threatening information," says Kensinger.
