“…Four classes were identified in the previous section from a review of the literature: learning (White, 1973;Kazanas and Chawhan, 1975;Gatti-Petito et al, 2013), intelligence (Roberts, 1976;Schwark, 2015;Goksu and Gulcu, 2016;Nkhoma et al, 2017), autonomy (Dorais et al, 1999;Goodrich et al, 2001;Wiest, 2012), and communication (Bateman et al, 1990;Jäger and Rogers, 2012). We have chosen to base the learning subclasses on Gagne's Hierarchical Theory of Learning (Soulsby, 2006), a common hierarchy for learning.…”
