[Visual perception in normal children and adults II. Correlation between dominance of visual field and dominance of the eye].
To clarify more precisely about the correlation between the dominance of visual field and dominance of the eye, tachistoscopic examination was performed on 48 normal adults; 24 males and 24 females, and 24 right-handed and 24 left-handed subjects. The mean of the time of exposure was less than 4.5 msec. The time of exposure was independent of handedness, dominance of the eye, sex, or the type of stimulus. Four right-handed and four left-handed subjects showed dominance of the left visual field for the A value, suggesting no correlation between handedness and dominance of the visual field. However, six of those eight subjects were found to have dominance of the left eye for the A value, and all seven subjects with dominance of the left visual field for the D value showed dominance of the left eye (chi 2 = 16.39, p less than 0.001). It was concluded that dominance of the eye was significantly correlated with visual field. It is therefore important to examine dominance of the eye as well as dominance of the visual field for evaluation of cerebral dominance with regard to visual perception.
