Concepts

Vygotskian scholars don’t use “Ecological Mind” to describe Vygotsky’s ideas. I just use the term to highlight Vygotsky’s three ideas which are highly relevant to ecological approaches of psychology: Zone of Proximal Development (ZPD), Perezhivanie, and Social Situation of Development.

One of Yrjö Engeström’s major theoretical contributions is Developmental Work Research which is based on the concept of Zone or Zone of Proximal Development.

Andy Blunden’s Project-oriented theoretical approach is a major development of Activity Theory in the past decade.

The hierarchical structure of activity was originally conceptualized by A. N. Leontiev (1978). We have to notice that the goal of Leontiev was developing a psychological theory at the individual level with the concept of Activity.

The concept of Mediation is important for Activity Theory. Since the theoretical traditions has different versions, the concept of Mediation also has different versions.
