Biological Sciences and Psychology personal statement example

Personal statement example

In a Biology lesson last year our teacher handed out cards printed with colour words in mismatched inks, the word 'green' in red, 'blue' in yellow, and asked us to name the ink as quickly as we could. Most of us stumbled. What interested me afterwards was not that reading is automatic, which I had half expected, but that the delay could be measured in fractions of a second and that it differed between people. It suggested that something happening in the brain, a biological process, could be studied through simple behaviour. That link between living tissue and observable action is why I want to study biological sciences and psychology together.

My A-level Biology course gave me the cellular side of the picture. I enjoyed the topic on nerve impulses, particularly how the sodium-potassium pump restores resting potential and why myelination speeds conduction. Chemistry helped me understand why neurotransmitters bind to particular receptors, and Maths has been more useful than I predicted, especially statistics. When we learnt the t-test, I finally had a way to ask whether a difference was real or just noise.

That led to a small project of my own. With my teacher's permission I timed twenty classmates on an online reaction-time task, once on a morning after their usual drink and once after a caffeinated one, swapping the order for half of them. The averages were slightly faster after caffeine, but the difference was not significant with such a small group. I was not disappointed. Writing it up taught me more than a neat result would have: I noticed that people improved simply by practising the task, that I had no control over how much sleep anyone had had, and that relying on volunteers who drink coffee was itself a bias. I later read about how psychology has wrestled with studies that fail to replicate, and my project made that debate feel concrete rather than abstract.

Reading has widened what I understand by the subject. Oliver Sacks's The Man Who Mistook His Wife for a Hat showed me how damage to specific brain regions can alter perception in ways that patients themselves struggle to describe. It made me realise that biology alone cannot explain an experience, and that careful observation of behaviour and of what people report matters just as much. I am keen to learn how researchers connect these levels, from genes and synapses to memory and decision-making.

Outside school I work weekends at a garden centre. Most of the job is watering, restocking and answering questions at the till, but I have become the person colleagues ask about why seedlings in the far greenhouse wilt sooner. Checking the temperature at different benches showed that one corner caught the afternoon sun, and we moved the most delicate trays. It was a small piece of practical problem-solving, and I liked doing it. The job has also made me comfortable talking to customers of every age, often explaining things simply without being patronising.

On Wednesday evenings I help my younger cousin with his homework. He finds reading slow, and I have noticed that he concentrates far better in short bursts with a break than in one long session. I cannot claim to know why, but it has made me curious about attention and learning, and it has taught me patience.

I also play badminton for a local club. Matches have reminded me how much reaction time depends on anticipation rather than raw speed, which brings me back to those coloured cards.

I want a degree where I can study the nervous system in the laboratory and also design experiments on behaviour, using statistics properly from the start. I am methodical, I enjoy working out what a result does and does not show, and I am ready to build on the modest foundations I have laid so far.
