 While the psychological mechanisms underlying social transmission are widely thought to play a foundational role, other cognitive abilities have been put forward as additional candidates for being key difference makers that allow human minds to produce and sustain unique forms of complex cumulative culture. Though the exact character of their respective contributions remains unclear, some prominent candidates include: novel and more powerful forms of memory (Donald 1991, 2007; Carruthers 2015), especially for particular sequences of actions (Ghirlanda, Lind, &amp; Enquist 2017; Milne, Wilson, &amp; Christiansen 2018; Petkov &amp; Cate 2020); imagination and mental time travel (Suddendorf &amp; Corballis 2007; Dor 2015, 2017; Fuentes 2017); analogical thinking (Brand, Mesoudi, &amp; Hewlett 2021); metacognition (Heyes 2016b; Dunstone &amp; Caldwell 2018; also see Heyes, Bang, et al. 2020); mindreading (Carruthers 2013; Heyes &amp; Frith 2014; Moore 2021; cf. McGeer 2007; Zawidzki 2013); social tolerance brought about by self-domestication (J. Henrich 2016; Hare 2017; Wrangham 2019); shared intentionality (Tomasello, Carpenter, et al. 2005; Tomasello &amp; Moll 2010); norm psychology (Chudek &amp; Henrich 2011; R. Boyd 2017; Davis &amp; Kelly 2018; cf. Andrews 2020a; Fitzpatrick 2020; also see Kelly &amp; Setman 2020); resolve (Ainslie 2021; Setman &amp; Kelly 2021); natural language (Ross 2007; Tamariz &amp; Kirby 2016; Dennett 2017: chapter 9; Sterelny 2020); narrative (Scalise Sugiyama 2001, 2017; B. Boyd 2009; Sterelny 2012); reasoning (Pinker 2010; Mercier &amp; Sperber 2011, 2017); and various tool and technological proficiencies (Vaesen 2012; A. Schulz forthcoming; Birch 2021; cf. Osiurak &amp; Reynaud 2020).
