In the August issue of Current Directions in Psychological Science, a journal of the Association for Psychological Science, Boston College psychologist, Elizabeth Kensinger and colleagues, explain when emotion is likely to reduce our memory inconsistencies.
Her research shows that whether an event is pleasurable or aversive seems to be a critical determinant of the accuracy with which the event is remembered, with negative events being remembered in greater detail than positive ones.
For example, after seeing a man on a street holding a gun, people remember the gun vividly, but they forget the details of the street. Functional Magnetic Resonance Imaging (fMRI), studies have shown increased cellular activity in emotion-processing regions at the time that a negative event is experienced.
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 intrinsically linked to the emotional aspect of the event, such as the exact appearance of the gun.
Kensinger argues that recognizing the effects 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 occurrences. “These benefits make sense within an evolutionary framework,” writes Kensinger. “It is logical that attention would be focused on potentially threatening information.”
This line of research has far-reaching implications in understanding autobiographical memory and assessing the validity of eyewitness testimony. Kensinger also believes that this research may end insight into the symptoms of posttraumatic stress disorder.

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.
Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
