“…In line with Aporta and Higgs (2005), other ethnographic research has cited decreased environment engagement as the main contributor to spatial memory impairment during guided navigation (Girardin & Blat, 2010;Leshed, Velden, Rieger, Kot, & Sengers, 2008). Cognitive research, on the other hand, has implicated lack of active investment in terms of mental effort and control (Parush, Ahuvia, & Erev, 2007;Péruch & Wilson, 2004), lack of spatial decision making (Bakdash, 2010;Bakdash, Linkenauger, & Proffitt, 2008), technological novelty (Ishikawa, Fujiwara, Imai, & Okabe, 2008), and Downloaded by [Florida International University] at 03:38 27 December 2014 divided attention (Fenech, Drews, & Bakdash, 2010). Clearly the debate has not been resolved, but whether this is because the contributing factors interact or because of wide methodological variation is unclear.…”
