Dear all, There is new study out for Android and iOS from the Institute of Neurology at University College London that seeks to determine if seeing smiling faces can make you happier. It is based on facial mimicry and we are comparing the effect of seeing smiling faces to landscapes and need many people to participate to see if this could become an effective complementary drug free intervention to battle low mood. Please download the app, participate, and disseminate at will: Website: www.pocketsmile.icn.ucl.ac.uk iPhone <https://itunes.apple.com/gb/app/pocket-smile/id709226955?mt=8> download link and Android <https://play.google.com/store/apps/details?id=uk.ac.ucl.pocketsmile> download link, Best wishes, *Javier Elkin* Doctoral Researcher in Applied Neuroscience | *UCL <http://www.ucl.ac.uk/> Awareness group <http://www.fil.ion.ucl.ac.uk/~grees/index.html>* *E: *javier.elkin.10(a)ucl.ac.uk *T:* +44 (0)7449 303450 *A:* Alexandra House, 17 Queen Square, London, WC1N 3AZ *LinkedIn*: www.linkedin.com/pub/javier-elkin/46/809/642 Download my happiness experiment for iPhone <https://itunes.apple.com/gb/app/pocket-smile/id709226955?mt=8> and Android <https://play.google.com/store/apps/details?id=uk.ac.ucl.pocketsmile>! @Innov8_4health <https://twitter.com/innov8_4health> @PocketSmileApp <https://twitter.com/PocketSmileApp>
