In this collection of essays, the four branches of radical cognitive science—embodied, embedded, enactive and ecological—will dialogue with performance, with particular focus on post-cognitivist approaches to understanding the embodied mind-in-society; de-emphasising the computational and representational metaphors; and embracing new conceptualisations grounded on the dynamic interactions of "brain, body and world". In our collection, radical cognitive science reaches out to areas of scholarship also explored in the fields of performance practice and training as we facilitate a new inter- and transdisciplinary discourse in which to jointly share and explore common reactions of embodied approaches to the lived mind. The essays originally published as a special issue in Connection Science.
