“…Furthermore, empirical findings could sufficiently separate L2 selfconcept variables from other subject-specific facets of academic self-concept. They also could demonstrate them to correlate with various performance variables in a domain-specific manner (Marsh, Kong & Hau, 2001;Möller, Streblow, Pohlmann & Köller, 2006;Onwuegbuzie, Bailey & Daley, 2000a;Rost, Sparfeldt & Schilling, 2007). As to that, there was clear evidence for distinguishing L2-related self-concept facets from related self-efficacy variables that represent the least aggregated, therefore the most concrete, level of task-specific competence and control beliefs (Bandura, 1997;Bong & Skaalvik, 2003;Mills, Pajares & Herron, 2007).…”
