Psychophysiological Mechanisms of Two Quantity Systems

Abstract

The study tests hypotheses about the activation of two quantity systems in different conditions of access to stimuli visual parameters. 23 participants (M=26,83 years, SD=9,78 years) performed tasks for non-symbolic comparison of quantities, for perceptual accuracy, for comparison of non-symbolic and symbolic quantities. As a result, new experimental data were obtained to explain the cognitive and psychophysiological mechanisms of the non-symbolic numerosity representation.
