“…Our approach may thus prove useful for measuring the disruptive effects of distractions and interruptions 6 on attention and performance (Altmann, Trafton, & Hambrick, 2014;Monk, Boehm-Davis, Mason, & Trafton, 2004;Trafton & Monk, 2007;Wilson, Farrell, Visser, & Loft, 2018). Distractions (i.e., when attention is partially diverted from the primary task; Graydon & Eysenck, 1989) and interruptions (i.e., when attention is entirely diverted from the primary task; Gillie & Broadbent, 1989) have been linked to negative outcomes in safety-critical contexts including aviation (Dismukes, Young, Sumwalt III, & Null, 1998;Loukopoulos, Dismukes, & Barshi, 2001, 2003, driving (Bowden, Loft, Wilson, Howard, & Visser, 2019;Ratcliff & Strayer, 2014;Strayer et al, 2015), and medicine (Coiera & Tombs, 1998;Tucker & Spear, 2006). For example, a ringing mobile phone can draw cognitive focus away from the road scene, leading to slower braking times and more severe lane deviations (Ratcliff & Strayer, 2014;Waard & Brookhuis, 1997) (see Averty, Collet, Dittmar, Athènes, & Vernet-Maury, 2004;Metzger & Parasuraman, 2001; for examples from air traffic control).…”
