The processes of perception of time and space are one of the main in human life, they make it possible to navigate in the environment and create an objectively correct idea of it (Elkin D. G., 1962; Tsukanov B. I., 2000). Features of human perception of time and space depend on many factors: sex, age and psychophysiological features, emotional state, physiological state of the brain (sleep, wakefulness, hypnosis) (Fress P., 1961; Dmitriev A. S., 1964; Elkin D. G., 1962; Dmitriev A. S., 1980; Rubinstein S. L., 1989; Lupandin V. I., 1991; Lupandin V. I., Surnina O. E., 1991; Moskvin V. A., Popovich V. V., 2000; Tsukanov B. I., 2000). Therefore, the hypothesis of this study was the assumption about the presence of features of the processes of perception of time and space in girls in different phases of OMC. The identification of these features will reveal the nature of changes in sensations and perceptions of the external world in women during the phases of OMC. A total of 50 girls aged 17 – 22 years were studied in five phases of OMC (menstrual, postmenstrual, ovulatory, postovulatory and premenstrual). Using the developed computer program “the Researcher temporal and spatial properties of the person” (Nopin S. V., Koryagina, Yu., 2003-2004; certificate of official registration no 2004610221 from 19.01.2004) were investigated: the time of simple sensorimotor reaction to light and sound, reaction time to a moving object (WFD), the choice reaction time, the duration of the individual minutes (IM), the accuracy of estimating the angular velocity of the object, playback duration of the time interval to light and sound, the accuracy of estimating and measuring time intervals. The results of the study show that during OMC there are changes in the nature of the processes of perception of time and space in girls. The time of simple sensorimotor reaction was the greatest in the postmenstrual phase, and the least-in the ovulatory and premenstrual phases. The greatest values of RDO time were observed in the menstrual and premenstrual phases. In the analysis of the choice reaction time test, the best results were shown in the menstrual phase and the worst in the premenstrual phase. The greatest duration of MI (close to astronomical time) was observed in the menstrual phase (60, 01 s.), and the smallest-in the premenstrual phase (57, 43 s.). In tests for the reproduction of sound interval, measuring segments, as well as the evaluation of segments and angular velocity of the object, the greatest errors were made in the premenstrual and menstrual phases, and the smallest - in the postmenstrual phase. Thus, the most favorable from the point of view of the processes of perception of time and space in girls is the ovulatory and postmenstrual phases, and the less favorable is the premenstrual phase. A more accurate reflection of the length of a minute of astronomical time is revealed in the menstrual phase.
