  • Researchers found a link between childhood deprivation, impulsive behaviour and addictions later in life
  • Behaviours include overeating, taking drugs, smoking cigarettes and gambling
  • A second study found adults living in deprived areas displayed similar impulsive traits


Children who have experienced deprivation are more likely to make more impulsive choices than those who don’t and can lead to addictions in later life - research has shown.


‘Trait impulsivity’, the preference for immediate gratification, has been linked to spending more on food, especially unhealthy, highly calorific food. Studies have shown that children who experience poverty and food insecurity tend to have a higher body-mass index as adults than those who do not.


Researchers from the School of Psychology at Aston University found a link between deprivation in childhood and impulsive behaviour – leading to addictions later in life. The findings, which are a culmination of six years of research, also found a further link between impulsivity, obesity and the cost of living crisis.


Professor Richard Tunney, head of the School of Psychology at Aston University, published a study in Scientific Reports earlier this year where he showed that children who experience deprivation make more impulsive choices than children who don’t.


The research team studied 146 children, with an average age of eight, living in some of the most deprived areas of England and compared them with children living in some of the most affluent neighbourhoods.


Children were given a choice between taking home a small amount of money (for example, £1) or getting £10 a week, or even more a year later. How long a person is willing to wait for the larger amount of money can be used to calculate a ‘discount rate’ that shows how much the waiting time reduces the value of the money.


An impulsive person might prefer £1 now because the value of £10 in six months is ‘discounted’ to less than £1 right now. This means that, for them, the £10, is discounted by £9 over the six-month wait.


A less impulsive person might be willing to wait six months for £10, but not wait for a whole year for £15. This means that, for them, the value of the £15 is discounted by £5 over the additional six-month wait. This discount rate is a measure of how impulsive someone is.


Commenting on the findings, Professor Tunney said: “The results showed that children living in the most deprived areas had significantly higher discount rates than children living in the least deprived areas, regardless of age or intelligence, indicating that deprivation was the causal factor in the children’s choice.


“This preference for immediate outcomes is a stable personality trait that remains constant throughout a person’s life.”


However, in the research team’s most recent study published by the Royal Society, they investigated impulsivity in over 1,000 older adults aged between 50 and 90.


The study found that older adults living in the most deprived areas showed the same preference for smaller-sooner financial outcomes as the children in the first study.


It also found that a person’s job predicted the choices they made. Adults working in technical or routine occupations, such as mechanics or cleaners, chose to receive smaller amounts of money than wait for larger amounts compared with people in professional occupations, such as engineers or scientists.


Professor Tunney added: “These findings are concerning because impulsivity doesn’t just predict obesity. These findings tell us a lot about why people living in poorer areas tend to be unhealthier than people living in wealthy areas.


“People who experience deprivation as children are more likely to choose to do things that, although they might be pleasurable in the short term, are unhealthy in the long run. This includes overeating, taking drugs, smoking cigarettes and gambling.


“We know too, that impulsivity can help to explain why some people go on to become addicts, while other people can avoid some of the more harmful effects of drugs and alcohol.


“Deprivation is one of many factors that can lead to impulsive behaviour throughout a person’s lifetime. Genetics also plays a role in impulsivity. Policymakers can’t do anything about a person’s genes but they can influence the nation’s long-term mental and physical health by minimising child poverty. Failing to do so will have long-term implications for the children living through today’s cost of living crisis.”

Aston University researcher develops new optical technique that could revolutionise medical diagnostics

New light technique could revolutionise non-invasive medical diagnostics Orbital Angular Momentum could be harnessed to improve imaging and data transmission through biological tissues Could eventually have potential to make procedures such as surgery or biopsies unnecessary. An Aston University researcher has developed a new technique using light which could revolutionise non-invasive medical diagnostics and optical communication. The research showcases how a type of light called the Orbital Angular Momentum (OAM) can be harnessed to improve imaging and data transmission through skin and other biological tissues. A team led by Professor Igor Meglinski found that OAM light has unmatched sensitivity and accuracy that could result in making procedures such as surgery or biopsies unnecessary. In addition it could enable doctors to track the progression of diseases and plan appropriate treatment options. OAM is defined as a type of structured light beams, which are light fields which have a tailored spatial structure. Often referred to as vortex beams, they have previously been applied to a number of developments in different applications including astronomy, microscopy, imaging, metrology, sensing, and optical communications. Professor Meglinski in collaboration with researchers from the University of Oulu, Finland conducted the research which is detailed in the paper “Phase preservation of orbital angular momentum of light in multiple scattering environment” which is published in the Nature journal Light Science & Application. The paper has since been named as one of the year’s most exciting pieces of research by international optics and photonics membership organisation, Optica. The study reveals that OAM retains its phase characteristics even when passing through highly scattering media, unlike regular light signals. This means it can detect extremely small changes with an accuracy of up to 0.000001 on the refractive index, far surpassing the capabilities of many current diagnostic technologies. Professor Meglinski who is based at Aston Institute of Photonic Technologies said: “By showing that OAM light can travel through turbid or cloudy and scattering media, the study opens up new possibilities for advanced biomedical applications. “For example, this technology could lead to more accurate and non-invasive ways to monitor blood glucose levels, providing an easier and less painful method for people with diabetes.” The research team conducted a series of controlled experiments, transmitting OAM beams through media with varying levels of turbidity and refractive indices. They used advanced detection techniques, including interferometry and digital holography, to capture and analyse the light's behaviour. They found that the consistency between experimental results and theoretical models highlighted the ability of the OAM-based approach. The researchers believe that their study’s findings pave the way for a range of transformative applications. By adjusting the initial phase of OAM light, they believe that revolutionary advancements in fields such as secure optical communication systems and advanced biomedical imaging will be possible in the future. Professor Meglinski added: "The potential for precise, non-invasive transcutaneous glucose monitoring represents a significant leap forward in medical diagnostics. “My team’s methodological framework and experimental validations provide a comprehensive understanding of how OAM light interacts with complex scattering environments, reinforcing its potential as a versatile technology for future optical sensing and imaging challenges.” ENDS https://www.nature.com/articles/s41377-024-01562-7 Light: Science & Applications volume 13, Article number: 214 (2024) August 2024 https://doi.org/10.1038/s41377-024-01562-7 Authors: Igor Meglinski, Ivan Lopushenko, Anton Sdobnov & Alexander Bykov About Aston University For over a century, Aston University’s enduring purpose has been to make our world a better place through education, research and innovation, by enabling our students to succeed in work and life, and by supporting our communities to thrive economically, socially and culturally.

Aston University researchers to explore using AI and fibre-optic networks to monitor natural hazards and infrastructures

Aston University is leading a new £5.5 million EU research project Will focus on converting fibre-optic cables into sensors to detect natural hazards Could identify earthquakes and tsunamis and assess civil infrastructure. Aston University is leading a new £5.5 million EU research project to explore converting existing telecommunication fibre-optic cables into sensors which can detect natural hazards, such as earthquakes and tsunamis, and assess the condition of civil infrastructure. The project is called ECSTATIC (Engineering Combined Sensing and Telecommunications Architectures for Tectonic and Infrastructure Characterisation) and is part of the Horizon Europe Research and Innovation Action (RIA), which aims to tackle global challenges and boost the continent’s industrial competitiveness. Converting telecom fibres into sensors requires new digital signal processing to overcome the limited data storage and processing capabilities of existing communication networks. To address this the project will use localised, high performance digital processing that will integrate artificial intelligence and machine learning. The researchers’ goal is to minimise algorithms’ complexity while providing extremely accurate real-time sensing of events and network condition. The new laser interrogation and signal processing technologies will be tested using existing fibre optic networks, including those underwater, in cities, and along railway infrastructure to assess their potential. Delivered by a consortium of 14 partners across seven countries, from academic and non-academic sectors, the research will start in February 2025 and will last three and a half years. The Europe-wide team will be led by Professor David Webb who is based in the Aston Institute of Photonic Technologies (AIPT). Professor Webb said: “There are more than five billion kilometres of installed data communications optical fibre cable, which provides an opportunity to create a globe-spanning network of fibre sensors, without laying any new fibres. “These traverse the seas and oceans - where conventional sensors are practically non-existent - and major infrastructures, offering the potential for smart structural health monitoring.” Professor Webb will be joined by fellow researchers Professor Sergei Turitsyn, Dr Haris Alexakis and Dr Pedro Freire.

EU-UK Trade Deal continues to stifle trade with 27% drop in exports since 2021

New report shows persistent stifling effects of the impact of the Trade and Cooperation Agreement on UK-EU trade relations Monthly data show a 27% drop in UK exports and a 32% reduction in imports to and from the EU between 2021 and 2023 Recommendations for policy interventions include to negotiate sector-specific deals, engage with individual EU countries, and work on reducing non-tariff barriers A comprehensive analysis by researchers at the Centre for Business Prosperity at Aston University reveals that negative impacts of the UK-EU Trade and Cooperation Agreement (TCA) have intensified over time. The new report, Unbound: UK Trade Post Brexit, also shows a 33% reduction in the variety of goods exported, with the agricultural, textiles, clothing and materials sectors most affected. To assess the impact of the UK-EU TCA, the authors analysed monthly import and export between the UK and the EU, from January 2017 to December 2023 and separated into pre- and post-January 2021 when the agreement came into force. The monthly data shows a 27% drop in UK exports and a 32% decline in imports from the EU. Lead author, Professor Jun Du of Aston University says: “The Trade and Cooperation Agreement introduced substantial barriers and there are ongoing and marked declines in the value and variety of UK exports and imports. Without urgent policy interventions, the UK’s economic position and place in the global market will continue to weaken.” The UK-EU TCA redefined trade and investment rules and market access between the UK and the EU. Since it came into force, the UK government has negotiated several trade agreements, but the EU remains the UK’s largest trade partner. Exports for most sectors have decreased since January 2021, although the impact is varied. Agrifood, textile and clothing and material-based manufacturing have been among the hardest hit, with substantial declines in both export value and the variety of products exported. At the same time, some sectors such as tobacco, railway and aircraft manufacturing have seen modest increases in varieties of products exported. On the import side, most sectors have shrunk in both value and variety, particularly agrifood products, optical, textile and material-based manufacturing. A few sectors, for example, ships and furniture, have demonstrated noticeable increases in import product variety. The large variations across different goods categories and EU trade partners underscore the uneven effects of Brexit and the TCA on UK-EU trade dynamics, highlighting the need to understand the nuances and come up with tailored strategies that address the unique challenges of each sector within the new regulatory environment. The researchers make recommendations, outlining how sector-specific negotiations, streamlining customs procedures with digital technologies and reducing regulatory divergence could mitigate some of the impacts. Dr Oleksandr Shepotylo, the report’s co-author says: “Our findings indicate a decoupling of the UK from key EU final goods markets, accompanied by a shift in UK supply chains toward geographically closer EU trading partners for exports and smaller countries for imports. “This shift raises concerns and underscores the urgent need for a strategic reconfiguration of UK supply chains to maintain competitiveness.” Professor Du continues: “The TCA has introduced considerable barriers to UK-EU trade, particularly through increased Non-tariff measures (NTMs). “Addressing these issues through targeted improvements to the TCA is crucial to ensuring that UK businesses remain competitive in the European market. A structured, multi-faceted approach is necessary.” To find out more about these findings, click here.
