Most people have had trouble remembering something they just heard. Now, a University of Missouri researcher found that forgetfulness may have something to do with being in a good mood.
Elizabeth Martin, a doctoral student of psychology in the College of Arts and Science, has found that being in a good mood decreases your working memory capacity.
Researchers gauged study participants’ mood before and after showing them a video clip. Some participants were shown a segment of a stand-up comedy routine, while others watched an instructional video on how to instal flooring. Following the videos, those that viewed the comedy routine were in significantly better moods after viewing the video, while the mood of those that viewed the flooring video had not changed.
