This book breaks down barriers between disciplines engaging with flow, by speaking from geography into psychology to establish geographical foundations for this psychological phenomenon. It frames and works with the multiple contradictions within the extant literature as productive rather than prohibitive, thereby encouraging collaboration across discrepancies as well as across disciplines. It incorporates new materials and perspectives to research on flow, including aesthetic theory, new materialism, more-than-human geographies, and critical development geographies to broaden the theoretical and empirical landscape of future flow scholarship. It also digs more deeply into pre-existing areas of interest within flow research than has been done before, for example, with respect to 'dark' flow, 'flowability' and (tele)presence, to facilitate more nuanced engagement with such terms. It takes a step back from the detailed empirical work that characterizes most current flow research to pose questions as to how such divergent, even contradictory, findings can emerge from scholarship on a supposedly universal experience that is purportedly robustly constructed, and whether this contrariness is necessarily problematic or emblematic of flow itself and therefore worthy of conceptual elaboration. Finally, it evokes global scale and long-term critical perspectives on the future evolution of flow to counteract the presentism within existing work that emphasizes immediate gains (e.g., performance, wellbeing, profit), in an attempt to pre-empt the worst ramifications of the progressive commodification and strategization of flow. This innovative book is of interest to scholars from a range of fields, from psychology, to business and human resource management, leisure studies, and critical human geography.
