Jelen dolgozat az éntudattal rendelkező élőlények tudatának fejlődését vizsgálja. Az első rész főemlősök és csecsemők tükörképükre adott viselkedéses reakcióit elemzi, a hangsúlyt az éntudat jelenlétére utaló viselkedésformák fokozatosan fejlődő jellegére helyezve. Áttekintést nyújt a különböző modalitásokhoz tartozó testsémák eltérő reprezentációiról és magyarázatot kíván nyújtani az éntudat önszervező kialakulására. A második rész a testsémák és az éntudat önszervező folyamatait a matematikai csoportelmélet és az eltérő logikai szintek elméletével írja le, valamint a környezet és az éntudat közti információáramlás többszintű, komplex modelljét mutatja be.Present paper investigates the development of mind in living creatures showing the signs of having self-awareness. Behavioral phenomena of primates and human infants appearing to their mirror image are analised in the first part of the paper, laying the emphasis on the gradual quality of development of self-awareness. A survey of different representations belonging to variant sense modalities is provided in order to explain the self-organizing emergence of self-awareness. The second part describes the self-modifying process of body-schemes and self-awareness using mathematical group-theory and the theory of sets as metaphorical devices. A multi-level complex model of information-flow between the mind and environment is outlined. The main purpose of the paper is to provide a better understanding of the phenomenon of downward causation and to fill the gap of the ancient question of the body-mind (brain-mind) problem. This rather ambitious contribution to mind research also implies vague hints for the ones that are concerned about the research of artificial intelligence.

The auditory two-tone streaming paradigm has been used extensively to study the mechanisms that underlie the decomposition of the auditory input into coherent sound sequences. Using longer tone sequences than usual in the literature, we show that listeners hold their first percept of the sound sequence for a relatively long period, after which perception switches between two or more alternative sound organizations, each held on average for a much shorter duration. The first percept also differs from subsequent ones in that stimulus parameters influence its quality and duration to a far greater degree than the subsequent ones. We propose an account of auditory streaming in terms of rivalry between competing temporal associations based on two sets of processes. The formation of associations (discovery of alternative interpretations) mainly affects the first percept by determining which sound group is discovered first and how long it takes for alternative groups to be established. In contrast, subsequent percepts arise from stochastic switching between the alternatives, the dynamics of which are determined by competitive interactions between the set of coexisting interpretations.
