(Press-News.org) Using eye-tracking — a technique for recording and analysing eye movements — a team from the University of Geneva (UNIGE) has shown that individuals with multiple disabilities can improve their social and emotional skills. Although these patients are often considered ‘‘untestable’’, nine young people have undergone personalised training over a period of one year, with promising results in terms of their ability to socialise. This work opens the way to new methods of assessment and support. It is published in Acta Psychologica.
Multiple disabilities involve a combination of severe intellectual and motor impairments, resulting in profound dependence. Often unable to express themselves verbally or through gestures, individuals in this population primarily communicate through muscle tone, eye movements, or facial expressions — signals that are sometimes difficult to interpret. As a result, they are often considered challenging to assess and support.
In 2022, using an eye-tracking device that records eye movements in response to specific images, a UNIGE team demonstrated that individuals with multiple disabilities can exhibit visual preferences. These findings paved the way for improved communication with such patients. Today, the same team, in collaboration with the University of Lille, is highlighting the benefits of personalised training using targeted eye-tracking tools.
“We have provided preliminary evidence that, with customised and adapted training, certain socio-emotional skills can be strengthened in children and adolescents with multiple disabilities. This suggests that they possess previously unsuspected learning abilities,” explains Thalia Cavadini, a doctoral research assistant at the UNIGE Faculty of Psychology and Educational Sciences, first author of the study and recipient of a research grant from the Swiss National Science Foundation (SNSF) for this project.
Eye-controlled video games
The originality of this training lies in the use of eye-controlled educational video games, developed using three specific software programmes. The first is Gazeplay, an open-source platform featuring a wide range of eye-controlled games, several of which were customised for the study. The second is Attention Eye, created by a group of master’s students at UNIGE to train key socio-emotional skills such as social orientation, emotion recognition, joint attention, and moral judgement. Finally, a game called Climb the hill, developed by an independent creator, was designed to train social and moral skills not addressed by the first two programmes.
Nine children, adolescents, and teenagers, aged between 7 and 18, were monitored over the course of one year, with 40 to 100 individual sessions. The results are promising: all participants showed improvement in their visual exploration by the end of the study. Furthermore, they made progress in at least one of the six socio-emotional skills tested: preferential attention to biological movement, social orientation, face exploration, emotional expression discrimination, joint attention, and socio-moral judgement.
New communication possibilities
“These results provide preliminary evidence that, with personalised training using eye-tracking tools, certain socio-emotional skills can be strengthened in these young people. They therefore possess previously unsuspected learning abilities,” enthuses Thalia Cavadini. This pioneering study opens up new avenues for the assessment and support of individuals with multiple disabilities, highlighting the critical role of assistive technologies in enhancing their communication and socialisation.

How to protect bumblebee colonies safe from killer moths? Keep honeybee hives away from them
2025-04-10
Since the pandemic, we are very aware of the power of social distancing to protect against infectious disease. But can social distancing be effective if the infectious agent isn’t a virus or bacterium, but an insect powered by a brain and wings, and with the instinct to seek out new hosts?
Now, a study published to Frontiers in Bee Science has shown that physical distance does play a leading role in protecting bumblebees against a flying insect parasite, the bumblebee wax moth Aphomia sociella. The source of the potentially lethal infection was another species, namely nearby hives of domestic honeybees.
“Here we show that infestation with bumblebee wax moths is much greater ...
Rolling particles make suspensions more fluid
2025-04-10
Lacquers, paint, concrete—and even ketchup or orange juice: Suspensions are widespread in industry and everyday life. By a suspension, materials scientists mean a liquid in which tiny, insoluble solid particles are evenly distributed. If the concentration of particles in such a mixture is very high, phenomena can be observed that contradict our everyday understanding of a liquid. For example, these so-called non-Newtonian fluids suddenly become more viscous when a strong force acts upon them. For a brief moment, the liquid behaves like a solid.
This sudden thickening is caused by the particles present ...
Research fine tunes tools used to search for genetic causes of asthma
2025-04-10
Genome wide association studies (GWAS) have identified hundreds of genome regions containing thousands of genetic variants associated with asthma, but it’s still not clear which variants have an actual causal link to the disease. This “variant-to-function” gap is one of the biggest challenges to the usefulness of these genomic studies and has motivated researchers to develop new tools to make sense of GWAS results.
A new study by researchers from the University of Chicago combines genetic data and improved computational tools to look more closely ...
Meditation and critical thinking are the ‘key to meaningful AI use’
2025-04-10
People should learn to meditate and hone their critical thinking skills as AI becomes more integrated into daily lives, an expert suggests.
Digital strategy expert Giulio Toscani has spoken with 150 AI experts across 50 countries to understand the challenges and opportunities around human interactions with artificial intelligence.
He argues in his new book, Augmented: prAIority to Enhance Human Judgment through Data and AI, that as humans operate largely unconsciously by design, they are inclined toward immediacy and instant rewards, often overlooking potential ...
Studies shows new class of antibiotic is effective in tackling MRSA
2025-04-10
The development of new antibiotics to treat superbugs and other bacterial infections is a global priority, with the rate of infections that cannot be treated with current antibiotics rising and presenting one of the biggest threats to human health.
In line with that, new research has shown a daily dose of epidermicin NI01 – an antibiotic compound developed by University of Plymouth spinout company Amprologix – is as effective at removing Methicillin-resistant Staphylococcus aureus (MRSA) as the current standard of care.
The results were achieved through a robust skin MRSA infection model, and those behind the research say it justifies ...
Certain nasal bacteria may boost the risk for COVID-19 infection, study finds
2025-04-10
WASHINGTON (April 9, 2025) — A new study from researchers at the George Washington University has found that certain bacteria living in the nose may influence how likely someone is to get a COVID-19 infection. Published in EBioMedicine, the research reveals that certain types of nasal bacteria can affect the levels of key proteins the virus needs to enter human cells, offering new insight into why some people are more vulnerable to COVID-19 than others.
“We’ve known that the virus SARS-CoV-2 enters the body through the respiratory tract, with the nose being a key entry point. What’s new—and surprising—is that bacteria in our noses ...
Europe's population is adapting better to cold than to heat
2025-04-09
A study led by the Barcelona Institute for Global Health (ISGlobal), a centre supported by the "la Caixa" Foundation, has shown that Europe has adapted better to low temperatures than to high temperatures over the last two decades. The research, carried out in collaboration with the Barcelona Supercomputing Centre (BSC) and published in The Lancet Planetary Health, shows that there has been a significant decrease in cold-related mortality risk in recent years compared to the first decade of the 2000s. There has also been a reduction in the risk of heat-related ...
Ancient tools from a South African cave reveal connections between prehistoric people
2025-04-09
In a cave overlooking the ocean on the southern coast of South Africa, archaeologists discovered thousands of stone tools, created by ancient humans roughly 20,000 years ago. By examining tiny details in the chipped edges of the blades and stones, archaeologists are able to tell how the tools were made. In a new study published in the Journal of Paleolithic Archaeology, researchers analyzed these stone tools and discussed how the different techniques used to make them hint at the ways that prehistoric people traveled, interacted, and shared their craft.
“This is an important insight into how people who lived in this region ...
World’s first birth following conception with a fully automated remotely operated ICSI system
2025-04-09
10 April 2025: The world’s first baby has been born following conception with a fully automated, digitally controlled intracytoplasmic sperm injection (ICSI) system. ICSI, developed and adopted into widespread use in the 1990s and now a routine method of assisted conception, achieves fertilisation by injecting a single sperm cell into the centre of a mature egg.
The details are reported today in the peer-review medical journal Reproductive Biomedicine Online.(1) The automated system was described and developed by a multidisciplinary team of specialists from Conceivable ...
Girls’ education projects succeed when whole communities ‘live the change’ and carry it forward
2025-04-09
Education projects supporting marginalised girls in lower-income countries are more likely to achieve lasting transformations when they mobilise young women and their communities as “agents of change”, a new report indicates.
The recommendation comes from the latest evaluation of the Girls’ Education Challenge: a UK Government-supported initiative which has funded projects reaching more than 1.6 million girls. The University of Cambridge-led study finds that these projects initiated “virtuous cycles” of change – particularly by rooting themselves in communities and empowering young women to lead the way.
In ...
