One study has demonstrated this effect on older adults for the first time. Professor Ellen Peters, who co-conducted the study on this: “There have been many studies showing that young adults are more creative and have greater cognitive flexibility if they are in a good mood. However, the cognitive decline as a result of ageing meant that scientists were not sure whether this effect also applies to older adults. This research demonstrates that this is the case and that the ageing brain can be stimulated.”
The experiment
In one experiment, one group got two bags of sweets, and a thank you for taking part. The other group received nothing for their participation. Then, tests were carried out to see their memory and decision making.
“When you meet someone for the first time you have to find out if this is someone you can trust,” said Professor Peters. “People who are in a good mood learn faster and make better decisions.”
The working memory was tested by giving a range of numbers and letters to remember. The working memory plays an important role in making decisions. If several options oppose each other, how then can you remember of each option? Can you compare options and confront them simutaneously in your head? This is important to make a good decision.
The effects of mood
Professor Peters: “These results are good news in the context of the ageing workforce. The research findings show that being positive, and influencing the mood of people in a very simple manner will have a massive impact on the functioning of the brain.”
