Listening to Music While Studying Impairs Performance
A study found that listening to background music while performing cognitive tasks – yes, kids, such as studying – impairs overall mental performance and ability to do arithmetic or recall information later.
The surprising aspect to the study findings is that the interference with mental ability and ability to recall remained strong even when the music being heard is among a person’s favorite music; same as listening to music the subject hated. Quiet produced the best recall performance.
The researchers stressed that music might have some generally beneficial effect on our health but only when one listens to it prior to – never while – performing mental tasks or memorizing material. This study will be published in the September 2010 issue of the journal, Applied Cognitive Psychology. It is available early to read online at http://bit.ly/aCr5GE.
Vitamin D & Mental Agility
Cognitive performance is much improved among the elderly who are not deficient in vitamin D, and vitamin D deficiency may be common among shut-in seniors due to limited access to sunshine and other factors, according to a new study.
More than 1,000 study participants who were receiving home care were assessed for vitamin D status. Only 35 percent of participants had sufficient vitamin D levels and this group scored higher on cognitive performance tests than those who were deficient or insufficient in vitamin D. Pathways for vitamin D have been identified in the hippocampus and cerebellum areas of the brain; these are regions associated with planning, processing new information and forming new memories, suggesting vitamin D is important to the cognitive process and for independent senior living.
The study was released by the journal titled, Journals of Gerontology, Series A, Biological Sciences and Medical Sciences, in a summary format. But it is available in full-text format at: http://bit.ly/d2FtYY.
