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.'

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.

A team comprising HSE International Laboratory of Statistical and Computational Genomics researchers Aleksei Shmelev and Nikita Chervov, 2025 graduate of the HSE Faculty of Computer Science’s Master’s programme in Data Analysis in Biology and Medicine Ivan Gevorkov, and two students from the United States achieved an outstanding result at the 2026 NeuroGolf international machine learning championship. The team won a gold medal and placed seventh overall.
‘Working with AI Solves a Wide Range of Engineering Problems’
Artificial intelligence is a working tool based on a balanced combination of algorithms and engineering.

‘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.
Advancing Collaboration: HSE Faculty of Computer Science and Harbin Institute of Technology Hold Joint Seminar
From July 13 to 16, 2026, the Faculty of Computer Science hosted the Russian–Sino Research Seminar on Machine Learning Applications, organised by the HSE Laboratory for Cloud and Mobile Technologies in partnership with the Harbin Institute of Technology (China). A delegation comprising seven students and three university representatives travelled to Moscow to take part in an intensive four-day programme.
Physicists Find a Way to Model Ion Parameters in Plasma in Seconds
Researchers from HSE University and the Moscow Institute of Physics and Technology (MIPT) have developed a set of simple analytical methods for calculating the properties of heavy ions in helium under the influence of a strong electric field. The new approach speeds up calculations of ion mobility and ion–molecule reaction rates by thousands of times while maintaining sufficient accuracy for plasma jet modelling. The findings have been published in the journal Physica Scripta.

The 27th IEEE International Conference of Young Professionals in Electron Devices and Materials (EDM) has taken place in the Altai Republic. This year, researchers from HSE University presented the results of their research and were involved in organising a new section on artificial intelligence. A paper by HSE master’s student Rodion Sidorenko was awarded third place in the research paper competition at the conference.
Two Years of Growth or Decline: How to Choose an Investment Strategy
Economists from HSE University, together with colleagues from international universities, have analysed stock market movements over almost a century and proposed an investment strategy that could have delivered returns nearly twice as high as the market average. Their research suggests following a momentum strategy during periods of sustained market growth and switching to a value strategy after prolonged market declines. The study has been published in the Journal of Banking and Finance.
Researchers Reveal Link Between Attention and Communication Difficulties in Autism
Researchers at HSE University have examined how communication difficulties in children with autism are related to brain function. The findings show that not only language networks but also attention networks play an important role. The weaker the connections involved in maintaining focus and switching attention, the more pronounced communication difficulties were. The study has been published in European Child & Adolescent Psychiatry.
