Do Strong Right-Handers Prefer Popular Music?
Why do some people like popular music while others prefer less popular genres? A new study published on the journal Psychology of Music proposes a possible explanation for this, handedness. After examining the musical preferences and the handedness scores of 92 undergraduate students, S.D. Christman identified that the strength of handedness is an important factor in individual differences in musical preferences.
More specifically, strong right-handers compared to mixed-handers reported significantly decreased liking of unpopular music genres and marginally increased liking of popular genres. These differences do not appear to reflect differences in musical training or experience. According to the author of the study handedness is associated with differences in cognitive flexibility. Previous studies suggest that strong right-handedness is associated with decreased interaction between the left and right cerebral hemispheres, which in turn is associated with decreased cognitive flexibility across various domains. The author concludes:
A number of studies report differences between conservatives and liberals in musical preferences (e.g., Glasgow & Cartier, 1985; North & Hargreaves, 2007). For example, Glashow and Cartier (1985) reported that conservatives prefer music that is safe and familiar, presumably reflecting preference for popular, not unpopular, genres. Given evidence that strong right-handedness is associated with increased conservative attitudes (Christman, 2008), this suggests a possible three-way connection between strong right-handedness, conservative views, and a lack of open-earedness. Accordingly, future research on individual differences in musical preferences would be well advised to include strength of handedness as a variable.
Finally, in case you’re curious, here are some of the genres included in each category: (a) popular: modern rock, classic rock, heavy metal, alternative rock, modern pop, 80s pop, R&B, Rap, Hip-hop, country, (b) unpopular: soul, funk, jazz, blues, folk, avant-garde, world, electronica, reggae, ambient, house. The categorisation of popular and unpopular genres was based on record sales (conventional music was defined as popular genres with high numbers of sales, while unconventional music was defined as less popular genres with lower numbers of sales). Even though the proposed idea is interesting, handedness is probably only one of the factors that might explain individual differences in musical preference. For a different approach see a recently published study by Chamorro-Premuzic et al. (2011) who found that individual differences in music consumption are predicted by uses of music and age rather than emotional intelligence, neuroticism, extraversion or openness.
