Research conducted by Dr. Elizabeth Martin of the University of Missouri shows that positive emotions such as joy and pleasure instead reduce the ability to remember for a moment. However, negative emotions did not automatically improve memory.
In the experiments done, Dr Martin involve a number of volunteers who were divided into 2 groups. One group was shown some funny videos, while another group was shown a video tutorial that is sure boring tile installation.
After watching the video, all pastisipan undergo a series of tests to measure memory. The test was a series of numbers given orally through earphones, and participants were asked to name a few number in the sequence.
Compared with participants who watched a video tutorial tile installation, participants who watched more funny videos made a mistake. The difference is significant enough that Dr. Martin concluded that positive emotions can reduce memory.
“But positive emotions do not always bad. Although memory decline, someone who has a positive emotion usually just have a problem solving (problem-solving skills) are more creative,” said Dr. Martin in his report in the journal Cognition and Emotion, as quoted from Medicalnewstoday, Thursday (03/31/2011).
