The entire professional life of G.V. Sukhodolsky passed within the walls of the Leningrad-St. Petersburg University: from the time he graduated from the psychology department of the Faculty of Philosophy of Leningrad State University in 1962 until his last Gennady Vladimirovich Sukhodolsky was born on March 3, 1934 in Leningrad into a family of native St. Petersburg residents. Wandering with the parental family, evacuated from St. Petersburg to difficult years blockade, led to the fact that G.V. Sukhodolsky belatedly began studying at high school, after graduating from school he served in the army. G. V. Sukhodolsky became a student at Leningrad State University, being a completely mature person with a rich life experience. Perhaps it is precisely the adult attitude towards professional activity from its very beginning led to further extraordinary successes.
The entire professional life of G. V. Sukhodolsky passed within the walls of the Leningrad-St. Petersburg University: from the time he graduated from the psychology department of the Faculty of Philosophy of Leningrad State University in 1962 and until last days life. He went from a laboratory assistant at the first laboratory of industrial psychology in the USSR, where he worked under the direct supervision of the founder of engineering psychology, Academician B.F. Lomov, to the head of the department of ergonomics and engineering psychology.
Professor G.V. Sukhodolsky became one of Russia's leading experts in the field of labor psychology, engineering psychology and mathematical psychology, and had extensive experience in scientific, applied and pedagogical activities. The monographs and textbooks he wrote allow him to rightfully be called one of the founders of the Leningrad and then St. Petersburg school of engineering psychology.
G. V. Sukhodolsky led a large pedagogical work: he developed the original general courses"Application mathematical methods in psychology”, “Mathematical psychology”, “Engineering psychology”, “Experimental psychology”, “Higher mathematics, measurements in psychology”, as well as special courses “Structural-algorithmic analysis and synthesis of activities”, “Psychological service at the enterprise”, “Engineering -psychological examination of road traffic accidents.”
Participated in the organization and conduct of all all-Union conferences on engineering psychology from 1964 to 1990. Was vice president International conference in ergonomics (L., 1993), organizer and permanent leader of the scientific and practical seminar on psychological services of enterprises (Sevastopol, 1988–1992).
From 1974 to 1996, G. V. Sukhodolsky was the chairman of the methodological commission of the Faculty of Psychology, whose work contributed to the improvement of the training of psychologists. For two official terms, he headed the specialized Academic Council for the defense of dissertations in engineering psychology and labor psychology.
Under the leadership of G.V. Sukhodolsky, dozens of theses, 15 candidate and 1 doctoral dissertations.
G. V. Sukhodolsky, having acquired rich experience in private research various types professional activities (tracking systems, navigation, heavy industry, timber rafting, nuclear energy, etc.), developed the concept of activity as an open system that assimilates and generates mental and non-mental products, based on a systemic synthesis of humanitarian and natural science approaches in psychology. He proved the need for multiple theoretical concepts of complex psychological (and other) objects and developed a methodology for multi-portraiting such objects in empirical research and mutual mathematical-psychological interpretation in psychological theory and practice.
Practical application of the concept developed by G. V. Sukhodolsky in the field vocational training: creation of models of variable stochastic algorithms and algorithmic structures of activity, including algorithms of dangerous (emergency) actions that need to be taught to improve labor safety; development of methods for studying the actions of operating personnel at consoles and posts for various purposes, including in the control room of nuclear power plants; development of a method for optimal layout and ergonomic examination of panels and consoles; Creation psychological methods examination of road accidents. For many years

Over the past 20 years, this book has not only not become outdated, but has acquired new relevance. Because over the past period, no new generalizing monographs on the psychology of activity have appeared, and Russian modernity and the prospect of development in the context of globalization require psychological study and design of new systems of human-technical activities from schooling to production management, international marketing and political life.

I am grateful to the URSS publishing house for the opportunity to reprint this book of mine and hope for interest in it from possible consumers of scientific knowledge.

In Soviet psychology, the so-called “activity” approach developed, according to which the human psyche is formed and studied in activity and through activity. Based on methodological principle the unity of consciousness and activity, the conceptual apparatus and methods of psychology are created, theoretical and practical developments are carried out in psychological fields, as a result of which the activity approach is developed.

The main direction of this development is associated with the transition from explaining the human psyche by its activities to the psychological study and design of the activity itself as mediated by mental, as well as social and biological properties acting people, i.e. "human factor". The leading role here belongs to engineering psychology.

Engineering psychology is a branch of psychology that studies the relationship between man and technology in order to achieve high efficiency, quality and humanity of modern work, by designing it on the basis of the psychological principles of designing equipment, working conditions, professional training and on the basis of engineering principles of taking into account the human factor in people. -technical systems.

The new technical reconstruction of production based on computerization and robotization, the creation of flexible production systems is making significant changes to the existing forms of professional activity. The main functions of a specialist in production are increasingly becoming the programming of machines, their management and control. Labor activity in production, management and management, and with computerization in school and educational activities are increasingly approaching in basic terms the activities of operators. In this regard, engineering psychology becomes a direct productive force and, being organically connected with psychological science as a whole, takes on all complex system relationships between psychology and other sciences and production.

Despite certain achievements, activity design remains one of the central problems of engineering psychology and psychology in general, since the experience of psychological description of activity has not yet been generalized and there are no reliable means of psychological assessment, optimization and design of both old and, especially, new types of activity . For this reason, the problem of activity is recognized as one of the most important problems for theoretical and practical development. In particular, it is necessary to create such a psychological theory labor activity a person who would equip practitioners with clear knowledge of the psychological mechanisms of this activity, the patterns of its development and methods of using the results of psychological research to solve practical problems; it is necessary to create a psychological theory of joint activity, revealing its complex structure and dynamics, and ways to optimize it.

It is believed that the psychological theory of activity, which serves as a methodological basis for all psychological disciplines, is one of the most important achievements of Soviet psychology. However, in this theory there is vagueness and ambiguity in the interpretation of basic terms, the conceptual layer of the concept synthesized on the previous and additional apparatus is not generalized enough, poorly systematized and not brought together. Most general and special psychological concepts reflect the desire to limit the study of activity to narrow psychological patterns of mental functioning. At the same time, the actual professional, material, technical, technological and other non-psychological aspects of activities, from which the psyche of the “working person” turns out to be artificially separated, remain outside the study. Because of this desire in general psychology they try to reduce the subject of study to some kind of “mental”, “meaningful experiences” or “orienting activity”. Social psychology is primarily limited to interpersonal relationships and the phenomena based on them. In labor psychology, professiograms are largely reduced to psychograms, and psychograms are reduced to lists of professionally important properties or qualities that are not very specific to a particular activity. For the same reason, in engineering psychology, interactions between people and machines are reduced mainly to information interactions, which is also a certain result of cybernetic reductionism. In psychology, the study of activity is almost universally limited to its analysis, although this contradicts not only dialectics in general, but also specific psychological methodology and the practical use of results.

Thus, on the one hand, urgent state tasks have been set, in the solution of which psychology as a whole as a science should participate, and on the other hand, this participation is hampered by the shortcomings of psychological views on activity - shortcomings so significant that it is permissible to talk about the absence of a psychological theory of activity . Without at least the foundations (or beginnings) of such a theory, it is obviously impossible to solve the required problems correctly.

It seems that the above considerations sufficiently substantiate the relevance of the goals that we are pursuing and to which the content of the book, the logic and nature of the presentation are subordinated.

First of all, it is necessary to understand the existing psychological and other views on activity, to identify, generalize, clarify and systematize the conceptual apparatus of the psychology of activity. The first section of the book is devoted to this, in which “key” concepts are defined; the conceptual apparatus existing in the psychology of activity is identified and systematized; existing systemic concepts of activity are critically analyzed and evaluated.

The second section of the book sequentially sets out first the premises and theoretical scheme of the generalized psychological material, and then the conceptual structures reflecting the structure, need-value sphere, development and functioning, being and cognition of activities.

In conclusion, the results are summed up and some prospects for the development of activity psychology are outlined.

I consider it my duty to express gratitude to my teachers, staff and students for good attitude, support and assistance.

Gennady Vladimirovich Sukhodolsky was born on March 3, 1934 in Leningrad into a family of native St. Petersburg residents. Wandering with his parental family, evacuated from St. Petersburg during the difficult years of the siege, led to the fact that G. V. Sukhodolsky belatedly began studying at secondary school, and after graduating from school he served in the army. G. V. Sukhodolsky became a student at Leningrad State University, being a completely mature person with rich life experience. Perhaps it was precisely the adult attitude towards professional activity from the very beginning that determined further extraordinary successes.

The entire professional life of G. V. Sukhodolsky passed within the walls of Leningrad - St. Petersburg University: from the time he graduated from the psychology department of the Faculty of Philosophy of Leningrad State University in 1962 until the last days of his life. He went from a laboratory assistant at the first laboratory of industrial psychology in the USSR, where he worked under the direct supervision of the founder of engineering psychology, Academician B.F. Lomov, to the head of the department of ergonomics and engineering psychology.

Professor G.V.

The monographs and textbooks he wrote allow him to rightfully be called one of the founders of the Leningrad and then St. Petersburg school of engineering psychology.

G. V. Sukhodolsky did a lot of pedagogical work: he developed original general courses “Application of mathematical methods in psychology”, “Mathematical psychology”, “Engineering psychology”, “Experimental psychology”, “Higher mathematics, measurements in psychology”, as well as special courses “Structural-algorithmic analysis and synthesis of activities”, “Psychological service at the enterprise”, “Engineering-psychological examination of road accidents”.

Participated in the organization and conduct of all all-Union conferences on engineering psychology from 1964 to 1990. He was vice-president of the International Conference on Ergonomics (L., 1993), organizer and permanent leader of the scientific and practical seminar on psychological services of enterprises (Sevastopol, 1988–1992).

From 1974 to 1996, G. V. Sukhodolsky was the chairman of the methodological commission of the Faculty of Psychology, whose work contributed to the improvement of the training of psychologists. For two official terms, he headed the specialized Academic Council for the defense of dissertations in engineering psychology and labor psychology. Under the leadership of G.V. Sukhodolsky, dozens of theses, 15 candidate's dissertations and one doctoral dissertation were defended.

G.V. Sukhodolsky, having acquired rich experience in private research of various types of professional activities (tracking systems, navigation, heavy industry, timber rafting, nuclear energy, etc.), developed the concept of activity as an open system that assimilates and generates mental and non-mental products, based on a systematic synthesis of humanitarian and natural science approaches in psychology. He proved the need for multiple theoretical concepts of complex psychological (and other) objects and developed a methodology for multi-portraiting such objects in empirical research and mutual mathematical-psychological interpretation in psychological theory and practice.

Practical application of the concept developed by G. V. Sukhodolsky in the field of professional training: creation of models of variable stochastic algorithms and algorithmic structures of activity, including algorithms of dangerous (emergency) actions that need to be taught to improve labor safety; development of methods for studying the actions of operating personnel at consoles and posts for various purposes, including in the control room of nuclear power plants; development of a method for optimal layout and ergonomic examination of panels and consoles; creation of psychological methods for the examination of road accidents. For many years, G.V. Sukhodolsky was a member of the expert council on the problem of human factors at the Ministry of Medium Engineering of the USSR.

G. V. Sukhodolsky studied problems of mathematical psychology for many years. Among the ones he developed original methods include: the method of multidimensional labeled stochastic matrices for treating complex objects; a method for visualizing finite-dimensional objects in the form of a profile in parallel coordinates; method of using multisets, generalization operations, mixed multiplication and division of multisets and data matrices; new method assessing the significance of correlation coefficients using the Snedecor-Fisher F-test and the significance of the similarity - differences of correlation matrices using the Cochran G-test; method of normalizing distributions through the integral function.

The scientific developments of G. V. Sukhodolsky in the field of psychology of professional activity find their application and continuation in solving two of the most important problems of modern labor psychology and engineering psychology. The first task is to continue developing the theory of professional activity, methods of its description and analysis. This is a key direction in modern applied psychology, since the methodology, theory and tools for describing and analyzing activity are the basis for the development of all other areas of organizational psychology and solving applied problems: psychological support for business process reengineering, performance management, job specification, organization of group work etc. The work of G.V. Sukhodolsky in this direction is continued by S.A. Manichev (competency-based modeling of professional activity) and P.K. Vlasov (psychological aspects of organizational design). Second task - further development traditions of the activity approach in the context of modern cognitive ergonomics (design and evaluation of interfaces based on the study of human activity), as well as knowledge engineering. Usability, a scientific and applied discipline that studies the efficiency, productivity and ease of use of business tools, is gaining particular relevance and development prospects. The concept of analysis and synthesis of algorithmic structures of activity by G. V. Sukhodolsky has clear prospects for maintaining its importance in ensuring the ergonomic quality of interfaces. The multi-portrait methodology is used by V. N. Andreev (author of developments in interface optimization, now working in Vancouver, Canada) and A. V. Morozov (ergonomic assessment of interfaces).

IN recent years life, despite a serious illness, Gennady Vladimirovich continued to be active scientific activity, wrote books, supervised graduate students. Gennady Vladimirovich was awarded prizes from St. Petersburg State University for pedagogical excellence, for a series of monographs on the application of mathematical methods in psychology. In 1999 he was awarded the title “Honored Worker of Higher School of the Russian Federation”, in 2003 - “Honorary Professor of St. Petersburg State University”. The merits of G.V. Sukhodolsky have received wide recognition. He was elected a full member of the New York Academy of Sciences.

He is the author of more than 250 publications, including five monographs and four textbooks and teaching aids.
