Fig. 3

The group of musicians who primarily used the fingers of their left hand (n = 14) consisted of nine violinists, one violist and four cellists. The group of musicians who used the fingers of both hands equally (n = 11) consisted of five pianists, one flutist, one oboist, one bassoonist, one guitarist, one accordionist and one trombonist. No musicians were found who primarily used the fingers of their right hand (e.g., trumpet players). Two missing values were also reported in the T-FD assessments for the subgroup “both hands used”. Asterisk indicates post hoc significance tests (p < .05, Bonferroni). Error bars: ±1SE. Boxed values indicate the exact number of participants (expressed as a percentage) who showed higher asymmetry toward the right hand (above zero) or toward the left hand (below zero)
