The purpose of our research is to better understand how ageing affects cognitive processes, such as memory and attention. We are using computer-based tasks to study these cognitive processes.

We are currently looking for participants aged 18-35, who often experience feelings such as worry and nervousness. The study involves completing some computer tasks and a set of questionnaires. The study takes place over the course of two consecutive days. The first day will last approximately 2 hours and the second day will last roughly 1.5 hours. Participants will be paid £35 in total.

How do our experiences consolidate during sleep to form lasting memories and can sleep alter cognitive processes such as attention and memory? To answer these questions we are using computer-based behavioural tasks and polysomnography, an electrophysiological measurement of brain activity during sleep.

Participants (aged 18-30) will meet the researcher around 10am to complete some computer tasks, followed by an after-lunch nap for 90 minutes. There will be a second session in the evening of the same day to complete a second short set of computer tasks. Overall, including sleep and lunchtime, the experiment will take 5 hours and 45 minutes and participants will be compensated for their time (£58 in total).

We are looking for healthy volunteers aged 40 to 80 years and fluent in written and spoken English to take part in a study investigating the relationship between attention and memory, and how it influences behaviour across normal healthy aging.

The study will involve simple computer-based visual tasks. We will also ask you to complete some questionnaires about attention, memory, handedness, mood, personality, family history of dementia and general health. The study will take no longer than two hours to complete and you will be reimbursed for your time and reasonable travel expenses.
