HSE Psycholinguists Launch Digital Tool to Spot Dyslexia in Children
Specialists from HSE University's Centre for Language and Brain have introduced LexiMetr, a new digital tool for diagnosing dyslexia in primary school students. This is the first standardised application in Russia that enables fast and reliable assessment of children’s reading skills to identify dyslexia or the risk of developing it. The application is available on the RuStore platform and runs on Android tablets.
Reading is one of the most complex cognitive skills. It depends on phonological and orthographic processing and requires hand–eye coordination, memory, and attention. Dyslexia is a specific reading disorder characterised by impaired reading acquisition despite preserved nonverbal intelligence. According to the International Dyslexia Association, between 15% and 20% of people worldwide experience reading difficulties. Without timely diagnosis and support, children with reading problems may grow into adults who struggle to use written information in their daily lives.
However, if dyslexia is identified at the primary school age, children have the opportunity to compensate for the disorder and learn to read effectively. Psycholinguists at the HSE Centre for Language and Brain have developed LexiMetr, a tool for assessing reading skills and detecting reading disorders (dyslexia) in students across grades one to four. The application is available on RuStore.
Until now in Russia, reading performance has been assessed using a method adapted in the 1990s by Alexander Kornev, which involves reading a text aloud and answering comprehension questions. While this approach remains reliable and widely used, modern speech therapy practice requires more convenient, technology-based solutions, especially for large-scale screening.
LexiMetr, developed by the Centre for Language and Brain, offers an alternative. This digital test allows users to determine within three minutes whether a child’s reading performance meets age norms and indicates the risk or presence of dyslexia. No prior preparation is needed: all instructions are built into the interface, and results can be easily marked up and saved.
A distinctive feature of the test is its detailed age standards. The application includes data for three groups of children: Russian-speaking monolinguals, bilinguals from national republics, and children learning Russian as a foreign language. LexiMetr has also been successfully validated, demonstrating comparable reading performance between texts displayed on a tablet and traditional paper sheets.

'The LexiMetr test is the result of many years of work by a large team at the HSE Centre for Language and Brain. Our development draws on cutting-edge research in dyslexia, psychometrics, speech therapy, psycholinguistics, and UX design. We hope the application will support speech therapists and teachers in their daily practice. Accurate and timely diagnosis highlights a child’s reading difficulties and enables early intervention, giving children the opportunity to successfully master reading and avoid future challenges.'

Scientists Develop Algorithm for More Reliable Processors in Data Centres
Researchers from HSE MIEM and Samara University have developed the LRF-3D algorithm to automatically bypass idle nodes in three-dimensional networks-on-chip. Thanks to its hierarchical architecture, the algorithm outperforms existing solutions in both speed and path accuracy, improving processor reliability for use in data centres, supercomputers, and AI computing. The source code and test results are publicly available.
Researchers Rank Recommendation Algorithms Using Sports Tournament Model
Researchers from the AI and Digital Science Institute at the HSE Faculty of Computer Science have developed an approach for selecting recommendation algorithms more effectively. Their approach uses pairwise comparisons of algorithms to create a tournament table, with the overall ranking based on their performance across all datasets in the tournament. This can reduce the number of algorithms that need to be tested when developing new services, saving both time and money. The study was presented at the 32nd ACM SIGKDD Conference on Knowledge Discovery and Data Mining (KDD 2026).
Researchers Develop Method for Direct Generation of Regulatory DNA
Researchers at HSE University have developed a model for generating promoters and enhancers—DNA sequences that regulate gene activity. The model works directly with DNA nucleotides, without first transforming them into a continuous numerical representation. This solution could be useful for applications in synthetic biology and gene therapy. The study results were presented at the ICLR 2026 Workshop ‘Generative AI in Genomics (Gen^2): Barriers and Frontiers.’

In this interview with the HSE News Service, Laboratory Head Elena Iarskaia-Smirnova discusses the laboratory’s work.
Physicists Discover What Happens Inside a Stable Vortex
Large vortices with characteristic spiral arms are often observed in the atmosphere and the ocean. Physicists from HSE University have explained how these structures form and why they retain their shape. The researchers found that velocities at points located along the same vortex arc remain correlated even over long distances. At the same time, this correlation weakens rapidly with increasing distance from the vortex centre. These differences help explain the formation of spiral arms and may improve models of atmospheric and oceanic currents. The findings have been published in Physical Review Fluids.

‘The Peak of Stupidity’ and ‘The Valley of Despair’: HSE Economists Propose an Explanation for the Dunning–Kruger Effect
The Dunning–Kruger effect, which describes a sharp surge in self-confidence among beginners followed by an equally rapid decline as they gain experience, can be explained by the nature of the learning process and the acquisition of new knowledge. This conclusion was reached by Andrey Vorchik of the HSE Faculty of Economic Sciences together with independent researcher Murat Mamyshev. They developed a mathematical model of learning and demonstrated how subjective confidence is formed and changes as knowledge accumulates, as well as how teachers can reduce the ‘valley of despair’ experienced by learners.
Toffee and Risk: Scientists Discover Why People Who Crave Sweets Make More Impulsive Choices
Having a sweet tooth may be linked not only to eating habits but also to the way people make decisions. Researchers at HSE University have found that people with a preference for sweet foods tend to behave more impulsively—not because they want immediate rewards, but because they are less willing to tolerate uncertainty. These findings may help improve treatments for addiction. The study findings have been published in Frontiers in Psychology.
