Effects of Certain Lateral Dominance Traits, Music Aptitude, and Sex Differences with Instrumental Music Achievement

The effects of music aptitude, sex, handedness, eyedness, and footedness on music achievement and executive skills of elementary instrumental music students was explored. Handedness was defined for the present study as the observed preferred hand used for a specific set of familiar tasks; eyedness refers to sighting dominance; and footedness was defined as the observed foot preferred to perform selected familiar tasks. A five-way multivariate analysis (2×2×3×2×3) was employed to analyze the data. No conclusive evidence was found to show that combinations of eye and limb dominance, sex differences, and music aptitude variables affect music achievement or executive skill variables. Only music aptitude levels when considered alone strongly affected tonal, rhythmic, and performance achievement
