Do mental speed and musical abilities interact?

The relation between mental speed and musical ability was investigated. Seventeen subjects aged 3-7 years were divided into two subgroups: one (G1; n = 9) consisted of children who participated in an early childhood music program and who received informal musical guidance, but no special training; the other (G2; n = 8) consisted of highly talented young violin players who received intensive parental support and special training by daily deliberate practice. Mental and musical abilities of both groups were controlled by standardized tests (Kaufman's ABC and Gordon's PMMA) and compared with data taken from recordings of saccadic eye movement using online identification from an electrooculogram (EOG).
