Khokhlov N.A., Kovyazina M.S. (2016). The role of crossmodal interaction in psychological and brain organization of mathematical abilities. National Psychological Journal. 4, 59-70.

The paper analyzes the work of Russian and foreign scholars devoted to the role of cross analyzer cooperation in developing and implementing mathematical abilities. Crossmodal interaction is considered as an additional category of neuropsychological analysis that allows to extend the existing ideas about the psychological structure and brain providing the mathematical ability. There are data that confirm the relevance of studying the interaction of the senses. Many of the research on this issue are carried out using the synesthesia which is considered a rare phenomenon. However, both Russian and foreign works suggest that the interaction of analyzers is not characteristic only to those whose brain is synesthetic. The joint work of the senses is characteristic of every person since his/her childhood, and is an obligatory condition for cognitive processes.

Cross analyzer synthesis is assumed to play an important role in producing spatial representations and the ability to intuitively perceive the notion of quantity (evolutionary foundations of mathematical ability). On the brain level, these processes are provided primarily by functioning of parietal and tertiary cortical areas located at the junction of cortical analyzer areas and also temporal areas that border on the parahippocampal brain area.

When dealing with school mathematics the structure of mathematical abilities is changing due to verbal and symbolic representations of numerical coding. Dealing with symbols opens up new opportunities, but it also narrows the spectrum of modalities involved in doing mathematical sums. Thus, the ability to re-encode information from one modality to another after school mathematics is perceived has an impact on the efficacy of mathematical activity. Doing mathematical sums is accompanied by crossmodal interaction that occurs on the unconscious level.

Some problem conditions may be efficiently processed in one modality, others may be solved in other modality.

Apparently, the ability to various crossmodal re-encoding patterns varies considerably from person to person. The effectiveness of crossmodal interactions may determine the severity of certain components of mathematical abilities and influence successful solutions of the corresponding types of mathematical problems.
