As this digital game involves a group of freely moving people, the experience is filmed using a synchronizing technique that links physiological data with events in the game. Behavior Measuring the Switch Cost of Smartphone Use While Walking Gabrielle Naïmé Mourra1, David Brieugne1, Emma Rucco1, Élise Labonté-Lemoyne1, François Courtemanche1, Sylvain Sénécal1, Marc Fredette1, Ann-Frances Cameron1, Jocelyn Faubert2, Franco Lepore2, François Bellavance1, Pierre-Majorique Léger1 1HEC Montréal, 2Université de Montréal This study design measures the task-switching cost of using a smartphone while walking. Participants undergo two experimental conditions: a control condition (walking) and a multitasking condition (texting while walking). Participants switch between these tasks and a direction determining task. EEG data as well as behavioral measures are recorded.
