Combining electroencephalography, the recording of the brain's electrical activity, with other psychological research techniques allows the link between memory and emotion to be investigated. This study, which is currently in the pilot phase, investigates the effect of emotions on performance in a memory test. Subjects are shown written memory cues with or without accompanying photos of strong facially-expressed emotions and later prompted to recall the written cues. By monitoring brain activity and recall success rate, emotion's effect on memory in this context can be determined, including what brain regions are stimulated by the emotion-memory link and the improvement or impairment of memory skills under the effect of outside emotional cues.
