The Phenomenon of Indirect Learning: Brain Mechanisms and Models

We studied an artificially constructed isomorphism between denotative (color) and lexical (geometric shapes) spaces and revealed the dynamics of formation of color-semantic representations in the process of indirect learning. We have detected the component of evoked potential (EP), which describes its changes from trial to trial in the process of learning; it significantly correlates with the value and direction of the errors. The results confirm the role of the brain structures that control movement (globus pallidus, caudate nucleus) in problems reconfiguring the system of relations between the sensory attributes of the reception of sign (visual cortex), and attributes of denotatum stored in memory (frontal cortex and parahippocampal gyrus) that occur during the formation of concepts.
