The link between musical expertise and linguistic working memory has been well established in the literature. However, new research from the University of Texas at Arlington suggests that musicians may have additional memory advantages, including enhanced visual/pictorial memory and better long-term memory.
In their study, lead author Heekyeong Park, assistant professor of psychology at UT Arlington, and graduate student James Schaeffer measured the electrical activity of neurons in the brains of both musicians and non-musicians using electroencephalography (EEG) technology, noting differences in frontal and parietal lobe responses.
“Musically trained people are known to process linguistic materials a split second faster than those without training, and previous research also has shown musicians have advantages in working memory,” said Park in a recent statement. “What we wanted to know is whether there are differences between pictorial and verbal tasks and whether any advantages extend to long-term memory.”
Study participants included 14 musicians, who had been playing classical music for 15 years or more, as well as 15 non-musicians. To test working memory, participants were shown both pictorial and verbal items and then asked to identify them among a group of similar foils. At the end of the session, long-term memory was tested by asking participants to identify test items they had already encountered versus completely new items.
On the working memory tasks, the musicians outperformed non-musicians in EEG-measured neural responses. In terms of long-term memory, however, musicians performed better in memory for pictorial (nonverbal) items only. Although the study does not establish the reason for this improvement in pictorial memory, the authors speculate that learning to read music may enhance an individual’s ability to process visual cues.
Dr. Park hopes to test more musicians soon to strengthen her findings. “Our work is adding evidence that music training is a good way to improve cognitive abilities,” she says. “If proven, those advantages could represent an intervention option to explore for people with cognitive challenges.”
The researchers presented their initial results last month at Neuroscience 2014, the international meeting of the Society for Neuroscience, in Washington, D.C. To learn more about Dr. Park’s work, visit her Web page on the UT Arlington Web site.
