PERCEPTUAL, MNEMIC AND SEMANTIC LEVELS OF A SUBJECTIVE REFLECTION

Comparison of different colour stimuli between each other has shown th at the whole quantity of colours is projected onto the surface of a sp here in a four-dimentional space. Geometric distances between the poin ts representing colours are directly proportional to subjective differ ences between the colours. Information on the perceptible colours is r ecorded in the long-term memory. Traces of the colour memory form a mn emic space isomorphous to a perceptive colour space. Traces of the col our memory are connected by means of two-way bonds with symbol represe ntation of colours which form a semantic colour space. Analysis of sub jective differences between the colour names has shown that the terms of colours are represented by points on the surface of a hypersphere i n a four-dimentional space. Colour stimuli being reflected at the perc eptive, mnemic and semantic levels become an act of consciousness with participation of the activating brain systems.
