Berstein's anti-reductionistic materialism: On the road towards a biology of activity (1965).

Bernstein's paper, "On the Road Towards a Biology of Activity," appeared the year before his death.2 With this paper, Bernstein closed several lines of argument that he had been developing from the onset of his career in the early 1920s. The paper converges on the notion of activity. In accordance with his own shifting focus heuristic (cf. Bongaardt, 1996), Bernstein challenged future researchers of movement to integrate models of the movement functions that constitute activity. He suggested that these functions are: the coordination of movement, the planning of movement, and the exploration of better, optimal ways to move. In the 1920s, Bernstein had collaborated with his friend and colleague L.S. Vygotsky at the Moscow Institute of Experimental Psychology. Vygotsky (cf. 1926/1994) was the first to place activity at the core of Soviet psychology. According to Vygotsky, reflexology and behaviorism, then dominant approaches in psychology, were fundamentally wrong; they focus on building-blocks of behavior without addressing phenomena that stand out as typically human, most importantly, consciousness. Rather than starting with building blocks, psychology should start with the daily activity of human beings in their environment and show how this activity relates to consciousness. Forty years later, in his 1965 paper, Bernstein stressed a point that mirrors Vygotsky's: Reflexes are not building blocks of movement. The general characteristics of any movement precede the specificity of such units, whether reflexes or synergies, and this primacy pertains to the actual organization of movements as well as to the study of movement. The development and relevance of the activity concept in Bernstein's work in the period from 1925 to 1965 deserves a study of its own; here, a brief historical sketch of Bernstein's activity concept is offered, along with a few theoretical considerations concerning activity's constituent functions.

Exploratory Behavior↗

[Definition of the stress concept and its use in various areas of medicine].

The triphasic adaptation reaction of the organism to every kind of demand, originally described by Selye, is a normal adaptation phenomenon which does not evoke any pathologic appearances in the healthy man, but on the contrary fulfills functions furthering the functional capacity. In man not biological, but frequently repeated, long-lasting psychosocial loads stand in the foreground, which may lead to gradually increasing phenomena, when a stress sensitivity and unfavourable social conditions are present. Hereby the changes in the biological field have secondary character. Far more decisive are disturbances of the behaviour which appear in psychosocial permanent loads which may lead to an increase of the risk factors for numerous diseases. When demands are insufficiently managed and a stress sensitivity is present a pathogenic stress may develop and evoke a chronic pathological process.

Adaptation, Psychological↗

[Trends and problems in psychophysiologic research].

Considering the increasing importance of psychophysiological investigations, the peculiar quality of psychological control functions in human organism is stressed. For this reason, specific definition of the initial conditions for psychophysiological experiments is necessary. If we use complex experimental schedules including electrophysiological parameters more and more differentiated results can be obtained. The different ways of information storage within the two hemispheres are considered as very conclusive. By means of a model of motor system the significance of internal feedback circuits is demonstrated. A statement concerning the mutual connections between biological and psychological events is given.

[Classification of mental phenomena as the highest integration level of man's relationship to the environment (with remarks on the phenomenon of altered states of consciousness)].

In recent years mystical ideas have been spreading concerning "altered states of consciousness" as "new dimensions of experience and transpersonal communication". An analysis is given of the class-conditioned character of these concepts deriving from the insecure social conditions existing under moribund imperialism. This is contrasted with the dialectical materialist concept of psychic phenomena as the highest integration level of man's relationship to the environment. Psychic phenomena are interpreted not as epiphenomena but as an expression of the new quality attained in the evolution of man as a social being in the central control of all functions of man's organism.
