Pursuit position gain, fixation duration and saccadic gain with music intervention in eye motion tracking

This study examined the impact of music intervention in tracking eye motion using videonystagmography. It compared the (i) pursuit position gain, (ii) fixation duration and (iii) saccadic gain in slow moving targets and fast moving targets, first without music and then with music. The experiment involved a group of children, 6 males and 12 females, all aged 11 years. They were exposed to smooth pursuit and saccadic moving targets in slow tempo (adagio J = 60) at 5 sec intervals between points and in fast tempo (allegro J = 120) at 2.5 sec between points. The study found differences in outcomes for slow tempo and fast tempo targets. In slow tempo, there was a significant difference in pursuit position and saccadic gain in both conditions of without music and with music. On the other hand, for the fast tempo, significant difference was found in fixation duration and saccadic gain for both conditions of without music and with music. These results point to the positive impact of music intervention on the pre-motor and motor ocular systems suggesting its influence on visual attention in different tempo zones.
