“…It was conceivably for the same reason that he (Vasileva & Balyasnikova, 2019) favored the terms 'cultural psychology' or 'cultural-historical psychology' (Lantolf & Beckett, 2009). Although it was in fact Wertsch (1985) (Robbins, 2007) which alongside Vygotsky's shifting views over the course of time, possibly contributed to the varied Vygotskian and post-Vygotskian interpretations in the SCT field itself (Ohta, 2016). Yet, despite the arguable fertility of "Vygotsky's philosophy" (Liu & Matthews, 2012) it tends to be predominantly identified with, for instance, the Zone of Proximal Development (ZPD) (Barrs, 2017;Chaiklin, 2003;Veresov, 2004) the impact of social interactions on the development of cognition (Lantolf, 2003; Van Compernolle.. 2015) the concept of mediation (Appel & Lantolf, 1994;Kozulin, 2003;Lantof & Thorne, 2006;Lantolf & Beckett, 2009;Lantolf, Thorne, & Poehner, 2015;Wertsch, 2007) and ultimately dynamic assessment (Lantolf & Poehner, 2010).…”
