This book explores how the Trajectory Equifinality Approach (TEA), which was introduced in Japan two decades ago by Tatsuya Sato, representsa central milestone for cultural psychology. It involves the use of both real (life events that happened) and imagination-based materials (life events that could have happened, but did not) in psychological data analysis. The potential of TEA is still to be found beyond our current understanding. While the origin of the TEA lies in Japan, where it has grown in popularity over time, today, an extraordinary community of researchers from multiple scientific fields recognises this approach and applies it to their research endeavours. Due to its uniqueness and wide range of application possibilities, this volume enhances the Trajectory Equifinality Approach for new pathways, perspectives and applications in the field. An essential aim of this contribution is to encourage individuals to connect themselves and their endeavours to TEA and thus possibly explore new viewpoints for their work.
