“…However, as these studies focused on declarative metacognitive knowledge, the question about the relation between procedural metacognition (monitoring) and ToM is still unanswered. Some authors have argued, based on findings concerning relatively good uncertainty monitoring skills in non-human primates (Call, 2010;Beran, Smith, & Perdue, 2013;Washburn, Gulledge, Beran, & Smith, 2010); as well as in infants and toddlers (Balcomb & Gerken, 2008), that for monitoring, no meta-representation of one`s performance in the task at hand is necessary. In other words, it has been argued that procedural metacognition may only rely on perceptual inputs and an ambiguity thereof rather than requiring the ability to reflect on one`s certainty or uncertainty (Lyons & Ghetti, 2010.…”
