Unconsciously perceived information as a basis for decision-making in the classification process

The article contains an analysis of the experimental data, indicating the possibility of the influence of unconscious information on the subsequent cognitive processes (in particular, on the classification process in visual perception). It is a very important problem to find suitable experimental paradigm, that allow scientists to make quantitative measurements of the influence of unconscious information on the cognitive activity. The article deals with the experience of solving this problem using two research models: the masked priming paradigm and the Single-Image Rangdom-Dot Stereogramm (SIRDS).
