The semiotic approach to the analysis of cognition Daniil Berezhnoy Kira Nikolskaya Dep. of Higher Nervous Activity, Moscow State University, Russia
C. Darwin ( ) I. Sechenov ( ) W. Kohler ( ) E. Tolman ( ) "the difference in mind between man and the higher animals, great as it is, certainly is one of degree and not of kind" (Darwin, 1871, p. 128) Animal cognition – the key to the human mind In the phylogeny of thought and speech, we can certainty distinguish the pre-speech phase of the intelligence development and pre-intellectual phase in the development of speech. (Vygotsky, 1929)
Modern cognitive science Concentrated on the study of human cognitive processes. Evolutionary approach disappears. Animals are used only as a convenient material for the neurophysiological experiments. Theoretical basis - human psychology. Behavioristic approach to the animal studies: no mind, only behavioral realisation.

(semantics) Alphabet - 7 units number of 4-link semantic sequences is equal 7 4 if you leave the maze after getting food and come back there again, then food would always be available in food feeders. Exit from the food- area Cause: no more food Cause: possibility of multiple reinforcement Entrance to the food- area (maze) Feeders true false full empty Non-food area Cause: fear (high uncertainty)

Learning as creation of language: letters to sentences. During learning, the information is being re-coded, in such a way that amount of information contained by elementary information unit increases while the total number of these units (7±2) does not change. Levels of re-coding 2-n; segments as letters syntactic level 4-n; links as single words semantic level n; solution routes as sentences pragmatic level

Invitation to cooperate Possible ways of model development: 1) Comparison of the revealed cognitive patterns with the data in the field of human problem solving and linguistic activity. 2) The software simulation of the derived patterns and their appliance in artificial intelligence research. Comparison with existing solution finding algorithms (genetic, evolutionary algorithms in programming). 3) The use of symbolisation and semiotic approach as a method to formally describe and identify significant patterns in the dynamics of other systems (e.g. analysis of neurophysiological data). 4) Involvement of methodological approaches from the field of structural linguistics, cryptography, theory of artificial languages to extend the capabilities of symbolic data analysis (revealing the internal rules).
