This study aims to notice the level of development of some specific elements of the perceptual-motor process. We started from the hypothesis that Ist grade students who participate in extra-school physical activities have a high level of perceptual-motor potential. The sample studied consists of 65 children, primary school students, ages between 6-8 years old, divided into two groups. The first group G1 consists of 31 children who take part in other sport activities (athletics, gymnastics, dance), guided by their physical education teachers, 3 times per week. The second group G2 is represented by children who attend physical education classes, 2 times per week in school curricula. They are guided by physical education teachers. Second group G2 consists of 34 children. The research was scientifically proved by specialized literature. The statistics-mathematics method and the main statistics indexes have been used. According to Sidentop, 1984 there is no single validated and reliable standardized test that can assess lags or deviations in perceptual-motor development. So, the control tests applied were original and they studied perceptual-motor elements: body awareness, spatial awareness and temporal awareness. The body awareness test: the subjects were trained to perform four exercises, 2 for the arms and 2 for the legs. Initially, the movements were performed and repeated by children. Then, at command, each subject performed the 4 suggested movements as follows: in four steps in order suggested and in 6 steps in random order led by the teacher. The number of correct executions was recorded. The spatial awareness test: the subjects were required to estimate the number of regular walking steps necessary to cover a distance (10m). The number of steps estimated by the subject was recorded. The subjects was immediately asked to walk that distance and count the steps. After this execution the subjects were reminded the estimated number of steps and the existing difference was discussed. The result was recorded and compared with the estimated one. The temporal awareness test: each subject was given 4 small balls which he had to throw at a mobile target, a swinging wood circle with 1 m diameter, respectively 1.5 m height from 3 m distance. The number of successful throwing was recorded.
