Abstract

According to the rate of sexual maturation girls of 14-17 years (n = 137) were divided into three groups: girls with a normal rate of maturation (n = 90), those with an accelerated one (n = 30) and girls with retarded maturation (n = 17). Girls participated in the experiment on studying the influence of the sexual development rate on speed and qualitative characteristics of the sensory-motor response on visual and acoustic stimuli in a stochastic reflexometric program. Marked peculiarities of the performance of reflexometric tasks having fractal structure of interstimuli intervals were detected both in girls with an accelerated and retarded rate of maturation. More evident and significant differences were revealed in a complex task on visual differentiation. Its less qualitative performance was observed in girls with an accelerated rate of sexual maturation.
