“…From this perspective, the information available for metacognitive computations is directly dependent on the quality and quantity of accumulation of sensory evidence (Kiani and Shadlen, 2009;Kiani et al, 2014). In contrast, dissociations between first-and second-order performance (Weiskrantz et al, 1974;Del Cul et al, 2009;Rounis et al, 2010;Harsay et al, 2012;Hebart et al, 2016;King and Dehaene, 2014;Fleming et al, 2015) suggest that metacognition and first-order task performance are supported by differential (though related) sources of information (Cleeremans et al, 2007;Yeung and Summerfield, 2012;Charles et al, 2014;Maniscalco and Lau, 2016). It has been proposed that dissociations between first-and second-order performance are the result of differences in availability of supporting information (Baranski and Petrusic, 1998;Del Cul et al, 2009;Yeung and Summerfield, 2012;Fleming et al, 2015).…”
