Fighting Left Handers Promotes Different Visual Perceptual Strategies than Right Handers: The Study of Eye Movements of Foil Fencers in Attack and Defence

Table 2

Comparisons of the means calculated for the eye metrics (dwell time %, average fixation, and fixation count) for the identified AOIs relative to the opponent’s handedness—defensive actions.

AOI—area of interest; G—guard; F—foil (blade and tip); M—mask; AH—armed hand; LT—lower torso; UT—upper torso; FT—front thigh; LH—left-handed; RH—right-handed. #Standard deviation is given in parentheses. Subscript letters stand for the statistically significant differences for significant interaction effects AOI x opponent’s handedness. Subscript numbers stand for the statistically significant differences for significant main effects of AOI. For dwell time (%), —a,c,e,f,g,j,n,4,8, —b,d,h,i,k,l,o,1,2,3,5,6,7, —m.
