“…Experimental evidence has shown that the spatial knowledge acquired in VEs transfers successfully to the equivalent real word space (Foreman, Stanton, Wilson, & Duffy, 2003;Foreman, Stanton-Fraser, Wilcox, Duffy, & Parnell, 2005). VEs are increasingly used in experimental research to address questions about spatial processes in typical or atypical populations Jansen-Osmann & Wiedenbauer, 2004). Moreover, active exploration in VEs is thought to enable the acquisition of survey knowledge, especially when the environments depicted have a simple layout or are relatively small (Montello, et al, 2004;Richardson, Montello, & Hegarty, 1999).…”
