“…These findings closely accord with other results in the adult human (Gick & Holyoak, 1983;Homa & Vosburgh, 1976;Loewenstein, Thompson, & Gentner, 1999) and animal categorization literatures (Castro et al, 2010;Castro, Wasserman, Fagot, & Maugard, 2015;Katz & Wright, 2006;Maugard, Wasserman, Castro, & Fagot, 2014;Truppa et al, 2011; see also Chapter 5, this volume), in which multiple instantiations of a relational concept increase the salience of abstract properties of stimuli (see Chapter 6, this volume).
