Older drivers who lack confidence on the road could benefit from a new training plan being developed by researchers at Aston University.
The project will target older drivers’ ability to pay attention to different locations when moving at speed – known as their ‘attentional switching flexibility’. As people age, this ability, essential for safe driving, can slow down, with serious implications for drivers and others on the road.
Although older drivers are reported to have fewer collisions and pose a lower safety risk to other road users than other age groups, it is known they are much more likely to suffer from a lack of attentional switching flexibility, which can severely affect their confidence. Aston researchers believe the extra time it takes older people to shift their attention from one thing to another may be a major source of this problem, and have developed a new training plan to tackle the issue.
A team, led by Dr Carol Holland, Director of the Aston Research Centre for Healthy Ageing at Aston University’s School of Life and Health Sciences, will test participants with a series of visual prompts designed to gradually increase the speed at which they can focus their attention. They will then be placed in a driving simulator and asked to tackle difficult traffic situations such as at virtual roundabouts and road intersections.
Their performance on the simulator will be measured over a period of time to assess the degree of their improvement.
Dr Holland said: “Many older drivers give up driving because of concerns about their safety and a general loss of confidence on the road. We hope to be able to keep them on the road for longer because they tend not to be bad drivers at all – far from it. The issue is one of confidence; if this can be built up through a specifically-designed training programme such as the one we are developing, it will improve the safety not only of older drivers, but of other road users as well.
“No one has studied the impact of attentional switching costs on the proficiency of older drivers before. We want to change the untrue stereotype of older drivers as unsafe and help enable them to feel more confident and competent on the road.”
Delaying the point when people give up driving could have significant general health benefits. Early driver cessation is often a precursor of depression and isolation. Loss of independent mobility is also associated with ‘life space constriction’, which is linked to frailty and loss of independence.
It is also known that maintaining or increasing the proportion of older drivers on the roads in any area or region has a positive influence on the road transport environment and overall incident frequency.
A recent RAC study estimated that of the 500,000 drivers who turned 70 in 2013 in the UK, 170,000 of them will give up driving before they need to.
The project is part funded by the Rees Jeffreys road fund as a PhD studentship and will be conducted in collaboration with Professor Klaus Kessler of the Aston Brain Centre.

Paper published in the Journal of Materials Chemistry B
Bioactive Organic-Inorganic Hybrids with Improved Mechanical Performance
Human tissue including both soft tissue (e.g. skin) and hard tissue (e.g. bones) are continuously remodelled and regenerated throughout our lifetime. However, as we age our bodies’ ability to repair and regenerate significantly reduces. Healing in older adults can be particularly slow due to reduced cellular activity. As we age our bones become brittle and weaker and reduced bone density can be problematic for post-menopausal women. Consequently bone is the most widely transplanted material with the exception of blood. It is therefore very important to develop new and improved biomaterials for bone regeneration. Effective implant biomaterials can help tissue regenerate and significantly improve the quality of life of older adults in later life. Recently there has been a change in philosophy moving away from traditional materials (e.g. large metal plates that are inserted for life) towards developing new smart biomaterials that can help the body self-heal and eventually become absorbed and replaced by the body. Solid glass particles containing calcium and phosphorous (the main building blocks of bone) are now used widely clinically to treat small bone defects (e.g. orthopaedic bone grafting in non-load bearing sites, ossicular replacement, head and neck surgery, tooth root implants). The latest drive is to mimic nature by developing highly porous scaffolds which enhance blood flow and cell ingrowth to increase the rate of healing. However these materials are usually mechanically weak. Dr Richard Martin (ARCHA & EAS) in collaboration with colleagues at the Chinese Academy of Science have developed novel sol-gel polymer hybrids for bone replacement applications with vastly improved mechanical properties whilst still maintaining this porosity. A key feature of this work was ensuring that the organic and inorganic phases are strongly bonded together to stop the polymer from rapidly washing out from the hybrid which would reduce the strength. The work was recently published in the Journal of Materials Chemistry B; full details can be found at http://pubs.rsc.org/en/content/articlelanding/2014/tb/c4tb01776e#!divAbstract

Aston University Challenging Perceptions of Ageing
Aston University hosted a photograph exhibition of veteran athletes who still compete at an international level.
Photographer, Alex Rotas, showcased her work at Aston University from 31st October, which featured photographs of competitive pole-vaulters, long jumpers and hurdlers in their 60s, 70s and 80s. The exhibition was designed to challenge potential stereotypes of older men and women within the UK.
The exhibition featured as part of Aston University’s Well-Being Week an initiative for staff which aimed to encourage healthier lifestyles at work. Aston Research Centre for Healthy Ageing (ARCHA) at Aston University, whose research focuses on older people’s wellbeing, also showcased their research at the event.
Dr Carol Holland, Director of ARCHA, said; “Alex’s work not only challenges perceptions of older people but also raises awareness of there are still very much abled older people in our society. Aston’s well-being week encourages staff to keep active and lead healthier working lives, we are happy that ARCHA can be involved with upcoming events. Alongside ARCHA’s focus on scientific research into Ageing we also explore the impact of changes in political and social environment on older people. ARCHA’s Ageing Lives cluster not only looks at impact of health and care policies, but also attitudes and beliefs towards ageing such as managing medicines and keeping active”.

European Year for Active Ageing
Fibre-optic implant could monitor wounds for infection
Fibre-optic implants could be used to monitor healing wounds for signs of infection if research by Aston University scientists is successful.
A team of researchers plans to study how to turn fibre-optic technology that can measure temperature and detect biological signs of disease into a device for implanting into a wound at surgery.
Doctors currently tend to check for infection by monitoring a patient’s temperature, but catching the problem before it has had a chance to affect the whole body could stop it becoming more serious.
