The Effect of Perceptual-Semantic Blindness in Solving Semantic Problems with Visual Means Containing the Solution

Abstract

In the light of the Cultural-Historical Theory (L.S. Vygotsky) and the Theory of Transcendental Psychology of Perception (A.I. Mirakyan), the author considers the position and functional role of the perceptual process in the development of the mind of an adult. The hypothesis is that the functional role of perception in the mind of the person at the end of its period of maturation is subordinate to the higher mental functions, in particular, the process of thinking, which is based on the search for a person available memory capacity and the possibility of finding knowledge in the relevant external sources. Therefore, in semantic terms, visual perception can be excluded from a conscious process of finding semantic solutions. This suggests the subordinate function of visual perception in cognitive adult life and the virtually automatic nature of the process that serves the knowledge-based development opportunities. In this context, we presented and experimentally tested on 30 students the effect of perceptual-semantic blindness, which shows that the mental process of solving semantic tasks is in the main ignoring additional visual stimuli containing the solution in the general visual field. In contrast to inattentional blindness, these stimuli are constantly presented in the field of vision and perceptual blindness was due not so much to inattention, but semantic processes. The presented effect of perceptual-semantic blindness is clearly expressed in more than 60% of cases (up to 100% for graphical variants). This situation can be regarded as the result of a kind of sociocultural development, formed in the conditions of modern information technology society. It also points to the need for special and purposeful perceptual-cognitive training as one of the effective means of using unclaimed perceptual possibilities to avoid the phenomena of perceptual-semantic blindness. These means are especially important for the educational process.
