The author pays attention to the sources of the modern psychology of decision making, which one can find in of personal meanings theory of thinking. It is mentioned in the paper, that O.K. Tikhomirov appealed not only to the methodology of cultural_historical and activity approaches, but also to other methodological conceptions (for instance, K.

The article deals with the semantic theory of thinking worked out by O.K. Tikhomirov which is considered a unique epistemological phenomenon. By means of its development the theory demonstrates the assimilation of three types of scientific rationality beginning with classical type, passing to non- classical and then to post- non- classical. It is stated in the article that the transspective analysis allows the investigator to examine the formation of scientific theory and to reveal the reasons which determine the “paradigm shifts” taking place in psychology and which are connected with the objective tendencies of the development of scientific knowledge. The article shows the real examples of the ways how the theory falsifies itself forcedly producing the facts, which can be explained only by means of the transition to the new level of its system organization. In accordance with the facts mentioned we can observe the rise of the level of professionalpsychological thinking.

In the article is submitted the comparative analysis of the problem of understanding and research of the creative thinking, describing three approaches: the personal meanings theory of thinking (O.K. Tikhomirov), the theory of problem situations (A.M. Matjushkin), approach of Ya.A. Ponomarev.

The studies held within the O.K. Tikhomirov’s school in psychology of thinking pro vide an approach toward solving the following problem: what are the actual positions and the roles the emotions play in human thinking processes, and in general — in the systemic interactions between human beings and the universe.

The correspondence between a human being and the universe is reflected in emotions and in systemic psychological properties, such as meanings, senses, and values. The paper discusses psychological mechanisms of emotional reflection of these properties.

It was shown that motivation determines the various aspects of thinking: the goalsetting strategy, the perspective goalsetting, emotional regulations, the relation between concrete and abstract components, egocentric features. The most important point of motivational influences is connected with the moment of motivational conflict. This conflict may switch the thinking of the subject from cognition to the special personal activity. This kind of thinking activity may be defined as a conceptualization of conflict personality meanings.
