Scientists: Selective preservation of positive information can affect the memory of the elderly – RIA “VistaNews”

People who selectively remember positive information by selecting it from a neutral or negative, worse performing memory tests. Such conclusions were made by scientists from the University of California. Their results appear in the publication of Learning and Memory.

Scientists: Selective preservation of  positive information can affect the memory of the  elderly <- TEnd ->

For the study, Michael! Yassa, assistant professor of neurobiology and behavior and neurology, and his colleagues have developed and used a test that uses the participants to recall stories with different emotional content to the deficit and reduce the memory index, in particular, in the context of aging and Alzheimer’s disease.

The study involved 32 elderly people (21 women and 11 men, average age 74.8). After each story was read aloud, they were asked to read all the details that they could remember. The problem was repeated after 20 minutes and one week later. This has allowed neuroscientists to observe how people remember different information after the time has passed.
The test also passed the oral examination, the researchers estimated that the overall performance of the memory subsystem. It shows the difference between people, which had high playback performance and those with low (showing subtle memory impairment). Importantly, none of them did not suffer obvious memory problems, serious enough for clinical diagnosis.
In analyzing the results, the researchers found that the poorly performing older people are more “positivity effect” or the tendency to remember positive information. However, this was due to the preservation of the neutral material. On the other hand, high-performance older people could remember more from neutral stories by maintaining the positive parts.
