Успешность мальчиков и девочек старшего дошкольного возраста в выполнении интеллектуальных тестов достоверно не различается. Параметры фоновой кардиоинтервалометрии (НСК), которая регистрировалась перед выполнением вербальных задач (в форме направленного ассоциативного эксперимента, у мальчиков и девочек достоверно не различаются. Решение интеллектуальных задач приводит к мобилизации адаптационного ресурса как и у испытуемых старших возрастов сокращаются кардиоинтервалы по длительности с одновременным снижением их вариативности, возрастает вклад симпатоадреналового звена вегетативной нервной системы, уменьшается вклад кортикальных полей в управление сердечным ритмом и нарастает хаотизация этих процессов. Выполнение АЭ безэмоционального воздействия на ребенка (АЭ фону девочек сопровождается регистрацией НСК с достоверно более высокими значениями фрактального индекса β по сравнению с мальчиками. У девочек в ситуации максимальной стрессогенности эмоционального воздействия на участников эксперимента в виде штрафов за ошибки значения спектральной плотности на самой низкой частоте спектра (So) и фрактального индекса β имеют достоверно большие значения, чему мальчиков в этой же ситуации. Это позволяет заключить, что у девочек кортикальные механизмы управления кардиоритмом при выполнении когнитивных заданий более зрелые, чему мальчиков этого же возраста

Following J. Piaget, intelligence can be psychologically regarded as a high regulating level of the adaptation system to various changing environmental conditions [4]. Therefore, psychological adaptation covers both organismic and socio-psychological levels of the human functioning. The process of adaptation to the intellectual activity including the learning one is studied in physiological and psychological investigations and is viewed as a complex phenomenon having different time scales of operating mechanisms and characterized by different efficiency and high group variability. Special attention in researches of adaptation to intellectual activity is paid to the investigation of psychophysiological mechanisms of resource mobilization essential for the process of intellectual activity. Peculiarities of the mobilization of the adaptation resource of children and teenagers were studied in the developed psychophysiological model of managed cognitive stress [2, 5] including the creation of emotionally stressful situations by means of the evaluation of activity results. The intellectual activity, when cardiointervals were recorded, consisted of the directed associative experiment (AE) performance. Lists of words (nouns, verbs, adjectives and adverbs) in proportions corresponding to their frequency distribution in the Russian language [2] were used for the neutral set of the associative experiment as well as for the series with a positive and negative reward.
The main differential feature reflecting various efficiency of the intellectual activity in all age groups is the character of the heart rhythm dynamics under conditions of emotionally significant vocabulary load. It was shown that under conditions with a negative reward fractal manifestations of the activity of higher regulation levels were decreased and the increase of the sympathoadrenal activation took place in the majority of the study sample [5].
These dynamic features of providing cognitive activity have become the subject of quantitative assessments in the model of nonlinear stochastic cardiointervalometry (NSC) [6] (N.I. Muzalevskaya and V.M.Uritsky’s method). Continuing the development of R.M.Baevsky’ well-known approaches [1], the NSC method is based on the universal patterns of self-organization of complex interactive systems. These fundamental regularities served as the basis for the concept development of the fractal stochastic self-organization of homeostasis [9] and justification of system criteria of optimum and stability of the homeostatic regulation of adaptation processes [6,9]. Physiological interpretation of integral parameters of homeostasis used in the
NSC method including fractal β index in the process of adaptation to the cognitive task solution is also based on these fundamental regularities.
Thus, the chosen model of intellectual activity and the method of nonlinear stochastic cardiointervalometry can be used to study gender specific peculiarities of the intellectual efficiency and mechanisms of verbal task performance by boys and girls under conditions of various degree of emotional stress. The relevance of the problem is due to the presence of contradictory experimental data concerning the intelligence of men and women, boys and girls as well as psychophysiology of intellectual activity. A wide range of unsolved problems in this field has determined the research objective. It was hypothesized that under various emotional conditions the associative experiment performance by boys and girls would be accompanied by general dynamic peculiarities of NSC parameters and differential characteristics.
Methods of performing similar experimental work are best described in manuscripts [2, 3, 5]. The given research includes differential analysis for groups of boys and girls brought up in the same pre-school establishment with priorities of intensive verbal and logical development of children.
