7. Texting while walking: An expensive switch cost. A SIGNIFICANT COGNITIVE EFFORT IS REQUIRED TO DIVIDE OUR ATTENDING WHEN TEXTING WHILE WALKING. THE MORE THE EFFORT, THE MORE THE ERROR. https://www.sciencedirect.com/science/article/pii/S0001457519302908 Courtemanche, Francois, Elise Labonté-LeMoyne, Pierre-Majorique Léger, Marc Fredette, Sylvain Senecal, Ann-Frances Cameron, Jocelyn Faubert, and François Bellavance. “Texting while walking: an expensive switch cost.” Accident Analysis & Prevention 127 (2019): 1-8.

8. Research questions RESEARCH ON MOBILE MULTITASKING THUS FAR ONLY FOCUSES ON A LIMITED NUMBER OF IT TASKS THAT CAN BE PERFORMED WITH A SMARTPHONE: TALKING, LISTENING TO MUSIC, AND TEXTING Q1: To what extent to which these results generalize to other types of mobile multitasking behaviors such as reading while walking and gaming while walking? Q2: To what extent motor movement through physical space (i.e., walking vs. only standing) affects this phenomena?

9. PHASE 1 STANDING PHASE 2 WALKING A Control (No task) X X B Reading a document X C Writing an email X D Playing Tetris X X E Group Texting X X F Individual Texting X Experimental design 2-FACTOR WITHIN-SUBJECT EXPERIMENT: POSITION (STANDING VS WALKING) AND TASK TYPE

10. Methodology PHASE 1 STANDING: 30 subjects (14 males, 16 females; ages 21-43, M = 25.6 years, SD = 5.9 years) PHASE 2 WALKING: 48 subjects (walking) (20 males, 28 females; ages 18-46, M=25.5 years, SD=5.5 years). Counterbalanced 22 trials per condition Counterbalanced 40 trials per condition A A B F C C D D E E PHASE 1 PHASE 2

14. Next steps ▪▪ Investigate the role of smartphone addiction proneness on the task-switching cost of using a smartphone while walking. ▪▪ Understand the relationship between stress and the usage of smartphone while walking, as well as the impact of stress on the task-switching costs. ▪▪ Investigate the effect of smart watch usage on pedestrian and vehicular behavior.
