Aim. Identification of variability and connections of the motor and visual tests determined by left or right hemispheres of the brain. Material and Methods. 129 girls of 18.2±0.6 years considering themselves right-handed persons. The examinee suggested to perform tests: «an interlacing of fingers of hands», «crossing of hands» («Napoleon’s pose»), «applauding», «casting leg on a leg» («a leg on a leg»), «visual test» (to look on subject through an opening, alternately closing eyes). Assessment of appeal of photos of the male and female persons made of the left and right half («preference of the photo») was carried out. Results and Discussion. Noted reliable right-hand domination when performing tests «applauding», «a leg on a leg» and «vision of a subject by the right eye» whereas domination of the left hand in tests «an interlacing of fingers of hands» and «Napoleon’s pose» isn’t significant is noted. The test «applauding» showing weak, but reliable positive connections with other motor tests is the most informative in diagnostics of domination of the right or left extremity. In images both men, and women, girls attract the photos made of the right half of the persons reflecting «abstract logic» of the left hemisphere. At the same time in a men’s image girls attract «the abstract logic», in a female image - «emotional figurativeness» of thinking more attracts. Conclusions. Motor tests, visual test and test «preference of the photo» represent independent complexes that are explained by difference of the systems which are responsible for their performance.
