“…Single refereeing decisions can have major impact on the outcome (Dosseville et al, 2013;Hossner et al, 2019;Raab et al, 2019), and accurate decisionmaking (DM) performance is considered to be one of the most important characteristics that a referee should possess (Bar-Eli et al, 2011;Nabli et al, 2019). Ample research has been conducted to identify sources of referees' bias, and to reveal how accuracy of officiating can be improved (Dohmen and Sauermann, 2016;Morgulev et al, 2018;Schweizer et al, 2013;Spencer et al, 2020). Contributing factors that have been found to assist referees in their DM processes include physical fitness (Helsen and Bultynck, 2004;Leicht, 2008), perceptual ability (Helsen and Bultynck, 2004;Kittel et al, 2019;Cobanoglu et al, 2021), mental ability (Anshel et al, 2014;Castillo et al, 2017), visual attention (Pietraszewski et al, 2014;Spitz et al, 2018), rules knowledge, and game management (Mascarenhas et al, 2002).…”
