“…Several eye parameters were found to discriminate between internal and external cognition, but findings were not fully consistent across studies (Annerer‐Walcher, Körner, & Benedek, 2018; Benedek, Stoiser, Walcher, & Körner, 2017; Ceh et al., 2020; Franklin, Broadway, Mrazek, Smallwood, & Schooler, 2013; Grandchamp, Braboszcz, & Delorme, 2014; Huang et al., 2019; Johansson, Holsanova, & Holmqvist, 2006; Jubera‐García, Gevers, & Van Opstal, 2020; Konishi et al., 2017; Makovac et al., 2019; Palinko et al., 2010; Pelagatti, Binda, & Vannucci, 2018; Piquado, Isaacowitz, & Wingfield, 2010; Salvi et al., 2015; Smallwood et al., 2011; Smilek, Carriere, & Cheyne, 2010; Unsworth & Robison, 2018; Walcher et al., 2017). One reason for the observed inconsistencies could be that eye parameters are sensitive to specific characteristics of the employed internal and external cognition tasks.…”
