Store description excerpt
Have you ever noticed how many smiles are started by other smiles? Just like laughing, smiling is contagious. Participate in ground-breaking science to see if looking at smiling faces throughout the day can increase happiness! HOW IT WORKS: Day 1: Pocket Smile shows you images of smiling faces or landscapes for 10 days Day 10: Any changes in mood are tracked and the type of image you see switches for the next 10 days Day 20: You have completed the experiment! You can now choose what image type to see and the data is anonymously sent to UCL. FIND OUT MORE: Visit www.pocketsmile.icn.ucl.ac.uk for more information on this experiment supported by University College London, including news and updates!
