The Boundaries of Flow: when the balance between a person’s challenges and capabilities becomes imbalanced, an empirical investigation of the relationship between subjective experience, capabilities and challenge.

The problematic situation this doctoral research project investigates concerns how the quality of a person’s lived subjective experience is affected by differing degrees of challenge: a product of pressures and demands that overwhelm a person’s knowledge, skills and experience (capability). The cost of stress and the ways stress make people vulnerable to illness is well documented. Therefore, the purpose of this doctoral research project is – to identify the thresholds (points) where the balance between challenges and capability moves to imbalance. This study uses Flow Theory and Complex Systems Theory as the foundation for this research. A literature review of flow theory pertaining to the research problem identified deficiencies in the models, methods and practices. As a result, the project is divided into two sections. The first section developed a new synthesised model of experience using an innovative suite of methods. The insights gained from this model were used to inform the second phase of the research project. The second phase utilises a novel multi-paradigmatic design strategy grounded in a realist philosophy of science. This approach facilitated the development of a quasi-experimental protocol and construct elicitation method to investigate the individual participant's subjective experience of varying degrees of challenge in the sensory and affective domains, respectively. This project contributes to the knowledge gap in two distinct yet complementary ways. Firstly, the research identified a relational link between challenge and subjective experience. Secondly, as experienced by the individual, challenge is incremental and cumulative. Moreover, this doctoral research project realises the overarching research objective by developing a codebook and a new synthesised model of experience. When the model and codebook are combined, they can identify when a person’s challenges and capabilities are aligned and misaligned through the various instances and absences of experiential states. This contribution represents a proof of concept. Future work is required to develop the method's applicability in organisational environments to support and enhance people’s lived experience of work.
