Childhood musical training helps auditory processing in old age

June, 2011

Another study confirms the cognitive benefits of extensive musical training that begins in childhood, at least for hearing.

A number of studies have demonstrated the cognitive benefits of music training for children. Now research is beginning to explore just how long those benefits last. This is the second study I’ve reported on this month, that points to childhood music training protecting older adults from aspects of cognitive decline. In this study, 37 adults aged 45 to 65, of whom 18 were classified as musicians, were tested on their auditory and visual working memory, and their ability to hear speech in noise.

The musicians performed significantly better than the non-musicians at distinguishing speech in noise, and on the auditory temporal acuity and working memory tasks. There was no difference between the groups on the visual working memory task.

Difficulty hearing speech in noise is among the most common complaints of older adults, but age-related hearing loss only partially accounts for the problem.

The musicians had all begun playing an instrument by age 8 and had consistently played an instrument throughout their lives. Those classified as non-musicians had no musical experience (12 of the 19) or less than three years at any point in their lives. The seven with some musical experience rated their proficiency on an instrument at less than 1.5 on a 10-point scale, compared to at least 8 for the musicians.

Physical activity levels were also assessed. There was no significant difference between the groups.

The finding that visual working memory was not affected supports the idea that musical training helps domain-specific skills (such as auditory and language processing) rather than general ones.
