“…A positive impact of AR on emotions would improve students' cognitive processes and performance (Csikszentmihalyi, 1990;Efklides, Kuhl, & Sorrentino, 2001;Keller, 1979;Linnenbrink & Pintrich, 2002). Psychological states such as motivation, flow, cognitive benefits, reflection, and sense of presence are positively related to learning outcomes (Antonietti, Rasi, Imperio, & Sacco, 2000;Conole & Dyke, 2004;Dalgarno & Lee, 2010;Dunleavy et al, 2009;Lee et al, 2010). Due to the limited scope of this work, we concentrate our efforts on the observation of the psy-chological state in which an individual feels cognitively efficient, motivated, and happy, known as flow (Csikszentmihalyi, 1990), that has been widely recognized by many researchers as supportive of students' learning (Choi & Baek, 2011;Kye & Kim, 2008;Pearce et al, 2005).…”
