INDIVIDUAL FEATURES OF PERCEPTION OF THE VISUAL SPACE ON THE EXAMPLE OF GEOMETRIC ILLUSIONS AND FIGURES
He article describes the individual characteristics of the perception of the visual space in the process of performing experimental tasks (using the example of geometric illusions and figures). The study involved 50 subjects (students of the Faculty of Psychology) 18-20 years old of both sexes with normal visual acuity. Psychological diagnostics included Strelau's test questionnaire, Eysenck's questionnaire (EPI), Crown and Marlowe's approval motivation scale, Rotter's locus of control questionnaire, Schubert's risk appetite questionnaire (RSK), Taylor's method for determining the level of anxiety, Spielberger's anxiety test. The subjects were presented with optical-geometric illusions of Müller-Lyer, Poggendorf, Wundt-Fick and simple geometric figures (circle, ellipse, line, angle, etc.) using the package of computer techniques "Psychometrics". Quantitative measurements were carried out by the method of multiple equalization. The peculiarities of perception of visual illusions and geometrical figures by psychology students are revealed. The results of the experimental study testify to the susceptibility of the subjects to the presented optical-geometric illusions of Müller-Lyer, Poggendorf, Wundt-Fick. A general tendency towards underestimation of various parameters of illusions and simple geometrical figures (area, shape, length) is shown. The exceptions were the shape of a circle and an ellipse. Correlations were found between the parameters of visual perception and individual psychological characteristics of the personality (properties of the nervous system, level of anxiety and anxiety, propensity to take risks, approval motivation, extraversion / introversion). It is shown that the individual psychological characteristics of subjects affect the accuracy of perception of the visual space (or the magnitude of the distortion error), thereby causing the level of susceptibility to optical-geometric illusions and the degree of adequacy of the assessment of the parameters of geometric figures.
