We are looking at how memory is involved in processing numbers. You will be asked to remember some sequences of letters or coloured squares, while also completing some other computer based tasks. Tasks will be completed across 2 sessions. Each should take no more than 1 hour and will take place on campus (Schofield building 0.33 or 0.27). A £16 Amazon voucher will be provided for participating. Anyone who is over the age of 18, speaks English as their first language and has normal (or corrected to normal) vision and hearing can take part.
