Musical engagement may be associated with better listening skills, such as the perception of and working memory for notes, in addition to the appreciation of musical rules. The nature and extent of this association is controversial. In this study we assessed the relationship between musical engagement and both sound perception and working memory.
We developed a task to measure auditory perception and working memory for sound using a behavioural measure for both, precision. We measured the correlation between these tasks and musical sophistication based on a validated measure (the Goldsmiths Musical Sophistication Index) that can be applied to populations of both musicians and non-musicians. The data show that musical sophistication accounts for 21% of the variance in the precision of working memory for frequency in an analysis that accounts for age and non-verbal intelligence. Musical sophistication was not significantly associated with the precision of working memory for amplitude modulation rate or with the precision of perception of either acoustic feature.
The work supports a specific association between musical sophistication and working memory for sound frequency.
