The Psychology of Time

by YPU Admin on May 12, 2016, Comments. Tags: psychology, Research, and UoM

Introduction

My name is Emily Williams and I’m currently a first year Psychology PhD student at the University of Manchester (UoM). After completing my A-Levels in 2010 (Psychology, Sociology and Computing), I went on to study Psychology at UoM from 2011 to 2014, and the following year I completed a Psychology Masters at UoM also. During my Masters studies I managed to secure funding for a three year PhD which started in October 2015. As you can tell, I’m a huge fan of Psychology, and also UoM (when I finish my PhD I will have been here seven years!), but my main interest specifically is the Psychology of Time Perception – how people perceive time.

As a Time Perception researcher I believe that people have a type of ‘internal clock’ which is what gives us the ability to sense how time passes. The speed of the internal clock can be altered, which gives us the perception of time dragging when we’re bored, or flying when we’re having fun. Other things have been found to speed up the clock, including high body temperature, certain emotions, and even hearing a series of ‘clicks’ for five seconds. Time seems to pass more quickly in these situations, which makes us overestimate how much ‘real’ time has passed. The first year of my PhD will focus mainly on a certain quirk of the internal clock – people judge sounds to be longer than lights, even when they are both the exact same duration. People are also more sensitive to duration when using their sense of hearing, than touch and vision.

In Depth…

For my first experiment, my participants will be sat in a dim room in front of a computer, with their dominant hand holding a foam block containing a small vibration generator (like the one in your mobile phone) and their non-dominant hand poised to type in answers using a keypad. A green LED is attached to the foam block, and a speaker is behind it. The vibrating plate, LED and speaker will present sounds, lights and vibrations to participants, and in the first task they will have to estimate how long these lasted for.

In the second task they will be given two of these (e.g. a light and a sound, or two vibrations) and have to answer ‘which was longer’, and on the final task ‘which came first?’.

I will then look at people’s answers for these tasks, and check whether the classic overestimations of how long sounds were when compared to lights are present. I will then try to see if there is a relationship between how accurate people are in their estimations, and how well they can answer which was longer and which came first. My guess is that the better people are at estimating time using one sense (e.g. vision, touch or hearing), the better they are at telling whether time in this sense was longer than another sense, and whether this sense came first. What do you think?

Next year, I will be broadening my scope to other things that affect the internal clock. I will also be looking at possible applications for my research. For example, the ‘clicks’ that I mentioned earlier have been found to not only affect how we perceive time, but have the added bonus of increasing the amount of information we can take in, and also speed up how quickly we can react to things! Although these are quite short-lived bonuses, I might be able to invent a way to help people revise for exams, or be better at video games, using a series of simple clicks.

Visit this website if you’d like to know more about the Psychology of Time Perception, including how it may work in the brain. It has a great section on ‘temporal illusions’ where it explains many things which change the speed of the internal clock, making your perception of time seem faster or slower.

Take a look at this article on Time Perception by the BBC, which features an interview with Professor John Wearden, a notable time perception researcher, who also used to be Head of Psychology at UoM!

Collecting Cobalt and Developing a 'Green Energy Economy'

by YPU Admin on April 28, 2016, Comments. Tags: Cobalt, Earth Science, Green Energy, Metal, Research, and UoM

Introduction

My name is Ed Thomas and I am a first year PhD student studying Geomicrobiology. This involves looking at how bacteria and microbes interact with rocks, minerals and metals in natural environments.

Geomicrobiology is relatively new scientific field but is rapidly growing; it has strong applications in answering many of Earth Sciences most pressing issues including: remediation of contaminated land, nuclear waste treatment and disposal, and reducing the environmental impact of mining and metallurgy industries.

My A-levels were in Geography, Chemistry and Maths, and I’ve always had a keen interest in all things Natural Sciences. I went on to do an integrated masters degree in Earth Sciences at the University of Manchester where my thesis was on the geochemistry of soft tissue fossils.

This is where I found my passion for studying the relationships between the biosphere and geosphere and I subsequently made the switch to studying Geomicrobiology. In September 2015 I started my PhD which looks at understanding the bioreduction process of Cobalt with a hope of ensuring a secure and sustainable supply of this crucial metal into the future.

In Depth…

Why Cobalt?

Cobalt is one of only 4 elements classed as an ‘Energy Critical Element’ by the U.S. Department of Energy, the American Physical Society's Panel on Public Affairs and the Materials Research Society, and the European Union.

Due to its uses in the blades and magnets of wind turbines, in photovoltaic solar cells, and in rechargeable batteries for electric vehicles, ensuring a continuous and sustainable supply of cobalt is crucial to developing a ‘Green Energy Economy’ in the future.

What’s the problem?

Almost all of the cobalt mined in the world is as a secondary product, this means that we only find ores coexisting with other metals, usually copper or nickel.

In order to separate out and concentrate the different metals from the ore metallurgic processes often run at high pressure or very low pH. Then the metal compounds are reduced to obtain the pure metallic form.

These processes of acid leaching, froth floatation, and reduction often create hazardous and toxic products which are harmful to the environment and difficult to dispose of safely, as well as using lots of energy and electricity.

How is Geomicrobiology the solution?

Microbes and bacteria are constantly reducing and oxidising metals in the environment. Often these are very complex systems involving many species of bacteria and multiple metals and redox reactions.

If we can isolate individual species of bacteria that reduce certain metals in specific ways, then we can design reaction series to maximise the efficiency of the metal recovery process. By recreating and scaling up these naturally occurring reactions that have been perfected over millions of years of evolution, we will drastically be able to reduce the environmental impacts of the mining industry.

Additionally, there are certain unique reduction pathways that result in specialised end products such as nanoparticles which have a variety of uses. For instance, cobalt nanoparticles have potential uses in hydrogen fuel cells, medical sensors and imaging, cancer treatments, and high performance magnets.

Belly and the Brain: Research into nerve endings and the gut

by YPU Admin on April 14, 2016, Comments. Tags: Digestion, Digestive Tract, Guts, Life Sciences, Research, and UoM

Introduction

Hi, my name is Victoria Kinsley and I am just starting my third year as a PhD student in Neurosciences here at the University of Manchester.  I finished my Masters in Immunology and Immunogenetics in 2012 and started my PhD in 2013.  My PhD involves studying the nervous system in the gut and investigating a possible link between nerves and the immune response.  Hopefully this will help us to better understand how and why diseases of the digestive system occur and why some people are more susceptible than others. 

In Depth

The gut, or gastro-intestinal tract, is responsible for taking nutrients from food, and also for making sure any bugs we inadvertently digest are recognised by our immune system and eliminated quickly.  However, we all have naturally occurring (commensal) bacteria in there too that we need to tolerate in order to be healthy.

The gut is full of nerves, so many in fact that it is known as the ‘mini-brain’.  It is controlled by these nerves along with input from the brain; however the mini brain is capable of working alone. Nerves are important to keep the gut moving and push through the contents, but it appears they may have another role as well; we know that there is a cross talk between this ‘mini-brain’ and the immune system to maintain a healthy gut environment, but this is not yet fully understood.  Some receptors and soluble factors are shared by both nerves and immune cells and these may work together to keep the gut healthy, but we don’t know yet how this impacts the progression of disease and recovery from illness.  Many people suffer from diseases and disorders of the gastro-intestinal tract and some, such as Crohn’s Disease and Ulcerative Colitis, have no known cure.  These patients seem to have slightly different gut nerves than those who are unaffected, and it may be that the nervous system in the gut plays an important role in driving the disease.  The gut is also affected in conditions such as diabetes, and changes in gut commensal bacteria have been linked with autism and depression, but further research is needed.

My research

My research aims to look at the nerves in the gut and investigate what is happening during and after infection to see if there is a long term impact on the nerve ‘maps’ that may then affect the way our guts respond to future infection or disease.  During the course of ordinary life our gastro intestinal tract works hard; we all encounter the odd bout of gut infection. Might this change our gut nerves and then affect our immune responses in the future? Might this be why some people get chronic gut disease and some people don’t? If we can understand the nervous system of the gut a little better we may get closer to being able to answer some of these important questions, and we may be able to help people suffering from gut disease.

Money Money Money: How do banks do it?

by YPU Admin on March 31, 2016, Comments. Tags: Banking, finance, Humanities, Law, Money, PhD, Research, and UoM

Introduction

Hi, my name is Max and I am a PhD student at the University of Manchester School of Law. I have been a university student for the past 6 years now and I have really enjoyed my experience. University provides you with the opportunity of learning new things, meeting new people, experiencing a new environment, and finding what it is you want to do in life. For me, particularly the last question has always been difficult: it took me a long time to realise what I wanted to do in life, but pursuing a masters degree after my undergraduate degree gave me an idea. I decided to do research in financial services regulation. I will give you an idea of what this entails. It’s all about money.



In Depth

Financial services significantly affect all members of society. You all use money to pay for different things, such as clothes, shoes, sweets, books etc. If it wasn’t for the financial services industry, money wouldn’t be readily available in the form that we use it today. Let me give you an example:

I imagine that some of you have bank accounts in which you can place your money. You can save money in your bank account and later withdraw it if you decide to spend it. This is referred to as a ‘deposit’, as you deposit your money in your bank account. Your bank can then use this money to create loans to give out to different people. A loan is simply an agreement between a bank and an individual or a company. The bank gives the individual a sum of money and the individual agrees to pay the money back over a certain period of time. For the bank to benefit from this transaction, the individual is required to pay an additional sum of money over the time period. It is up to the individual to decide what to do with the money they receive. They can spend it on clothes, shoes, sweets, books, or something substantially bigger like a car or a house. This bank, therefore, made money readily available to the individual. The money that you deposited is also still available to you. You can withdraw it at any time. All banks put together make up the financial services industry. They are an important part of the money available to us. They significantly influence how money is readily available to all members of society.


This seems like a good thing doesn’t it? Sadly, however, this system comes with its problems. Consider this: what if the individual is unable to repay their loan within the time period agreed upon? What if the bank gives out so many loans that there is no money left for you to withdraw when you want to? How does the bank decide who is suitable to receive a loan? Does the bank use any other means to finance its loans? All of these questions are addressed in financial services regulation. Research in this area essentially tries to make the financial services industry reliable and stable so that money is as readily available as described above. Many of the issues get very complex. It can be very difficult for researchers to keep up with everything that happens in the financial services industry. This is precisely why I believe this to be an interesting research area. New developments arise constantly that require addressing. Different researchers come up with different ways of addressing these issues. I have found myself able to add my own thoughts to this interesting area. It is a very rewarding experience.

The Brain in Pain

by YPU Admin on March 17, 2016, Comments. Tags: brain, Chronic Pain, Medic, Nerves, pain, PhD, Research, and UoM

Introduction

My name is Javin Sandhu. I am currently a medical student intercalating between years 4 and 5 of medical school to perform an MRes in Medical Sciences. This MRes course provides you with an opportunity to take on a research project that grabs your interest with a supportive supervisor who guides you through the process.

I was fortunate to do my research project in the processing of pain in the brain thereby combining my two core interests: neurology (study of the nervous system) and anaesthetics (drugs that work on the nervous system to put people to sleep). In addition, I have been fortunate to receive the John Snow for Anaesthetic Research funded by the BJA/RCoA to help support me during the master’s degree (please see http://www.niaa.org.uk/article.php?newsid=1454). 

In Depth…

When we experience pain, certain regions of the brain are activated. All these regions make up a “pain matrix”.  The pain matrix is divided into areas which process the location of pain and the emotional effect of that pain. Chronic pain and acute pain activate the same regions of the pain matrix but to different extents. These differences suggest that we should be aiming to develop ways of imaging ongoing clinical pain. Previous research from the Human Pain Research Group (see below for link), has shown success for treatment approaches such as meditation and placebo. This previous research has also shown an increase in a certain pattern of brain activity (known as alpha activity). There are various methods on how to image the brain’s functions. These approaches depend on how the brain uses oxygen (showing brain activity) or the electrical activity of the brain (which shows which brain cells are transferring information).

What do I investigate?

My research is based upon trying to find a unique pattern of brain activity for chronic pain by measuring the brain’s electrical activity in patients with chronic pain caused by rheumatoid and osteoarthritis.  I will be using EEG to pick up the brain’s electrical activity and analysing this data to figure out which areas of the brain are activated. We hope to find a unique pattern of brain activity which can be used in the future to test patients with chronic pain. This would help figure out how much pain these patients are in and to prevent patients which are addicted to painkillers “faking their chronic pain”.
