“…Double stimulation is primarily described as a method (Burman, 1996;Krange & Ludvigsen, 2008;Spiridonov, 1997;Valsiner, 2000;Van der Veer, 2001), although some refer to it also as a process (Gillespie & Zittoun, 2010), a theory-method (Muthivhi, 2011;Shotter, 1989) and a principle (Kozulin, 1990;Ritella & Hakkarainen, 2012;Sannino, 2011). While actual descriptions of double stimulation as a method are available, contemporary literature does not explain these other interpretations.…”
