moo-Q is a scientific iPhone application designed by the Hungry Mind Lab team at Goldsmiths, University of London with the aim of measuring mood and brain power. It allows users to see at what time of day their brain works best, and whether being in a good or a bad mood has an effect on brain power. This data is also securely and confidentially gathered by the researchers at Goldsmiths in order to assess whether there is a correlation between mood and cognitive performance. Users will complete a set of exercises, lasting no longer than a few minutes, several times over the course of a few days. Doing so unlocks their moo-Q performance chart. moo-Q is free for users across the world to download. For more information, please visit our website at www.hungrymindlab.com .
