This first sense of social cognition is therefore cognition about the social (i.e. persons and social entities) and it should not be confused with two other meanings. Social cognition can also refer to the knowledge obtained via others (i.e. persons or institutions). Social epistemologists tend to call this acquisition process testimony (Chinn, Buckland, & Samarapungavan, 2011; Coady, 1995; Fricker, 1995), a term that is now widely used in developmental psychology since the pioneering work of Paul Harris and colleagues (Clément, 2010; Harris, 2002, 2012; Koenig, Clément, & Harris, 2004). Finally, social cognition can also be understood as the knowledge acquired thanks to a collective process of reasoning in a group (Moshman, 1998).
