“…This may have occurred because the animacy effect on JOLs is mediated by differential processing fluency. In Experiment 2a, we investigated the possibility that processing fluency, as measured by study time (e.g., Castel et al, 2007;Koriat, 2008;Koriat & Ma'ayan, 2005;Koriat, Ma'ayan, & Nussinson, 2006;Miele, Finn, & Molden, 2011;Mueller et al, 2014;Undorf & Erdfelder, 2015), mediates the relationship between animacy and JOLs. Study time is inversely related to JOLs (e.g., Castel et al, 2007;Koriat, 2008;Undorf & Erdfelder, 2011), and hence is arguably a candidate for mediating the animacy effect on JOLs.…”
