Chapter 15: Body, Mind, and Movement: Some Proposals for Constructing a Socially Inclusive Psychology Based on Developmental and Cultural Principles

Zittoun and Gillespie’s (this volume) present an innovative new analytic strategy that further advances a potential methodology for the discipline of cultural psychology. This chapter aims to further advance psychology based cultural and developmental principles, through the construction of a new qualitative research methodology. This methodology has been labeled Trajectory Equifinality Analysis (TEA). In what follows, it will be outlined and then applied to the case of June’s diary writing.

In this section, we will describe Trajectory Equifinality Analysis (TEA) as a promising new analytic tool that is focused on any process within irreversible time. TEA consists of three sub-components, which can all be considered to be working within the perspective of cultural psychology (Sato, Hidaka, & Fukuda, 2009; Sato, Fukuda, Hidaka, Kido, Nishida, & Akasaka, 2012; Sato, Yasuda, Kanzaki & Valsiner, 2014). Figure 15.1 is a triarchic model for presenting the integrated view of Trajectory Equifinality Approach. This scheme explains not only each component, but also the mutual relationships between them. The three sub-components will be described in turn.
